HMS Manchester was a Town-class light cruiser built for the Royal Navy in the late 1930s, one of three ships in the Gloucester subclass. Completed in 1938, she was initially deployed with the East Indies Station and had a relatively short but active career. When World War II began in September 1939, the cruiser began escorting convoys in the Indian Ocean until she was ordered home two months later. In late December Manchester began conducting patrols in the Norwegian Sea enforcing the blockade of Germany. Beginning in April 1940 the ship played a minor role in the Norwegian Campaign, mostly escorting convoys. She was assigned to anti-invasion duties in May–November in between refits.
In November the cruiser was tasked to escort a convoy through the Mediterranean and participated in the Battle of Cape Spartivento. Manchester was refitting during most of early 1941, but began patrolling the southern reaches of the Arctic Ocean in May. The cruiser was detached to escort a convoy to Malta in July and she was badly damaged by an aerial torpedo en route. Repairs were not completed until April 1942 and the ship spent the next several months working up and escorting convoys.
Manchester participated in Operation Pedestal, another Malta convoy, in mid-1942; she was torpedoed by two Italian motor torpedo boats and subsequently scuttled by her crew. Casualties were limited to 10 men killed by the torpedo and 1 who drowned as the crew abandoned ship.[Note 1] Most of the crew were interned by the Vichy French when they drifted ashore. After their return in November, the ship's leadership was court martialled; the captain and four other officers were convicted for prematurely scuttling their ship.
Design and description
The Town-class light cruisers were designed as counters to the Japanese Mogami-class cruisers built during the early 1930s and the last batch of three ships was enlarged to accommodate more fire-control equipment and thicker armour.[2] The Gloucester group of ships were a little larger than the earlier ships of the class and received additional armour.[3] They displaced 9,400 long tons (9,551 t) at standard load and 11,650 long tons (11,837 t) at deep load. The cruisers had an overall length of 591 feet 6 inches (180.3 m), a beam of 62 feet 4 inches (19 m) and a draught of 20 feet 7 inches (6.3 m).[4] They were powered by four Parsons geared steam turbine sets, each driving one shaft using steam provided by four Admiralty 3-drum boilers. The turbines developed a total of 82,500 shaft horsepower (61,500 kW) and were designed to give a maximum speed of 32 knots (59 km/h; 37 mph).[5] During her sea trials on 28 March – 7 April 1938, Manchester achieved an average speed of 32.6 knots (60.4 km/h; 37.5 mph) from 84,461 shp (62,983 kW).[6] The ships carried enough fuel oil to give them a range of 6,000 nautical miles (11,000 km; 6,900 mi) at 14 knots (26 km/h; 16 mph). The ship's complement was 800–815 officers and ratings.[5]
The Town-class ships mounted twelve BL six-inch (152 mm) Mk XXIII guns in four triple-gun turrets, one superfiring pair each fore and aft of the superstructure. The turrets were designated 'A', 'B', 'X' and 'Y' from front to rear. Their secondary armament consisted of eight QF four-inch (102 mm) Mk XVI dual-purpose guns in twin mounts. Their light anti-aircraft armament consisted of a pair of quadruple mounts for the two-pounder (40-millimetre (1.6 in)) ("pom-pom") anti-aircraft (AA) guns and two quadruple mounts for 0.5-inch (12.7 mm) Vickers AA machine guns. The ships carried two above-water, triple mounts for 21-inch (533 mm) torpedoes.[7] The Towns lacked a full-length waterline armour belt, although the sides of the Gloucester group's boiler and engine rooms and the sides of the magazines were protected by 4.5 inches (114 mm) of armour.[7] The top of the magazines and the machinery spaces were protected by 1.25–2 inches (32–51 mm) of armour. The armour plates on the main-gun turrets had a thickness of 2–4 inches.[3]
The cruisers were designed to handle three Supermarine Walrus amphibious reconnaissance aircraft, one on the fixed D1H catapult and the others in the two hangars abreast the forward funnel, but only two were ever carried in service. A pair of 15,000-pound (6,800 kg) cranes were fitted to handle the aircraft and the ships' boats.[8]
Modifications
When Manchester returned home in November 1939, she was refitted with degaussing equipment and probably had her aft high-angle director-control tower (DCT) fitted. During a brief refit in November 1940, the ship was probably equipped with a Type 286 search radar. During a longer refit in January–March 1941, Manchester's hull was reinforced and her Vickers machine guns were exchanged for an ex-Army 40-millimeter Bofors AA gun atop 'B' turret and five 20-millimetre (0.8 in) Oerlikon AA guns. A Type 284 gunnery radar was installed on the roof of the main armament DCT atop the bridge during this refit. Additional splinter plating to protect the secondary armament and torpedo tubes was probably added at this time, as was an ASDIC sonar system.[9]
Two additional ex-Army Bofors guns reinforced the ship's anti-aircraft suite before she participated in Operation Substance in June 1941. Manchester was torpedoed during this convoy escort mission and while she was being repaired in the United States and Britain, she received three more Oerlikon guns for a total of eight weapons, six of which were positioned in the superstructure, one on the roof of 'X' turret and one on the quarterdeck. Two more ex-Army Bofors guns were added amidships before the ship participated in Operation Pedestal in August 1942. When the repairs were completed in April 1942, her radar suite consisted of a Type 279 early-warning radar, the Type 284 system for her main armament, two Type 285 gunnery radars for the four-inch guns, a Type 273 surface-search radar to replace the Type 286 and probably a pair of Type 282 gunnery radars for the "pom-pom" directors.[10]
Construction and career
Manchester, the first ship of her name to serve in the Royal Navy,[11] was ordered on 23 October 1935 from Hawthorn Leslie and Company. The ship was laid down at their Hebburn shipyard on 28 March 1936 and was launched on 12 April 1937 by the wife of Joseph Toole, the Lord Mayor of Manchester. She was commissioned on 4 August 1938 and departed for her first duty assignment with the 4th Cruiser Squadron in the East Indies on 24 September.[12]
After arriving in the British Colony of Aden, Yemen, on 12 October, Manchester was met by the heavy cruiser Norfolk, the station flagship, and the two ships proceeded to Bombay, British India, and then to Trincomalee, British Ceylon by the end of the month where they spent the next month working up. They spent the next month making port visits on the western coast of British India before returning to Ceylon for a maintenance period in Colombo's dockyard. Ports along the Bay of Bengal were visited in February–March 1939, before the two cruisers arrived in Singapore in the British Straits Settlements on 13 March. They conducted exercises with the aircraft carrier Eagle, the heavy cruiser Kent and the submarine depot ship Medway off the eastern coast of Malaya for the next several weeks.[13]
Visiting Port Blair in the Andaman Islands en route on 28 March, Manchester arrived at Trincomalee to prepare for a refit in Colombo. Rising tensions in Europe caused the refit to be delayed for a week and her refit was completed in early June. She began a tour of Indian Ocean ports on 6 June, supporting an aeronautical survey in Diego Garcia three days later with fuel and supplies before arriving in the British Protectorate of Zanzibar on 20 June. The ship began moving up the African coast until she rendezvoused with her sister ship Gloucester, the new station flagship, at Kilindini Harbour in British Kenya on 14 July. The sisters sailed to Aden when they met the sloops Egret and Fleetwood later that month to practice convoy escort tactics in light of the potential threat posed by Italian colonies on the Red Sea.[14]
Early war service
Manchester had just returned from a patrol in the Red Sea and the Gulf of Aden when Britain declared war on Nazi Germany on 3 September 1939. Together with Gloucester, she sailed for Colombo after refuelling. On 25 September, the ship rendezvoused with the sloop Rochester to help escort an Indian troop convoy through the Red Sea. Manchester escorted an Anglo-French convoy there before rendezvousing with the ocean liner RMS Empress of Australia in the Gulf of Suez to escort her to Colombo. The cruiser was ordered home on 10 November and arrived at Malta eight days later, where Vice-Admiral Geoffrey Layton hoisted his flag as commander of the 18th Cruiser Squadron (CS). The ship arrived in HM Dockyard, Portsmouth on the 25th and was docked to have storm damage and some other defects repaired.[15]
Her refit was completed on 22 December and she joined the Home Fleet at Scapa Flow two days later. Later that month, Manchester was attached to the Northern Patrol, where she was tasked to enforce the blockade of Germany, searching for German blockade runners and contraband material. On 21 February 1940 the ship helped to capture the 4,709-gross register ton (GRT) German merchantman Wahehe.[16] She remained on this duty until early April, although the cruiser was in Scapa Flow when it was attacked by German aircraft on 16 March. Manchester's gunners were unprepared for the attack and her shells were ineffectual.[17]
Norwegian campaign
Main article: Norwegian campaign
The 18th CS was relieved of its attachment to the Northern Patrol and was assigned to escort convoys to and from Norway. On 7 April Manchester, her half-sister Southampton, the anti-aircraft cruiser Calcutta and four destroyers were escorting the 43 ships of Convoy ON-25 bound for Norway. After the Royal Air Force (RAF) reported German ships in the North Sea, the convoy was ordered to turn back and the two light cruisers were to rendezvous with the Home Fleet in the Norwegian Sea. Their orders were later modified to patrol the southern part of the sea. Late on the 8th, the Admiralty ordered the ships to rendezvous with the Home Fleet lest they be caught between the two groups of German ships believed to be at sea; this was accomplished early on the morning of 9 April.[18]
Reinforced by their sisters Sheffield and Glasgow and seven destroyers of the 4th Destroyer Flotilla, the 18th CS was ordered to attack the Königsberg-class cruiser believed to be in Bergen, Norway, later that morning. That afternoon the RAF reported two cruisers in Bergen and the Admiralty cancelled the operation. The Luftwaffe had been tracking the squadron as it approached Bergen and bombers from KG 26 and KG 30 began attacking shortly afterwards. They sank the destroyer Gurkha and near misses damaged Southampton and Glasgow. That night Manchester, Southampton and the 6th Destroyer Flotilla patrolled off Fedjeosen to observe German forces in Bergen and prevent any resupply. The only incident that night was when Manchester spotted a submarine crossing between the two cruisers on the surface; the ship attempted to ram, but only managed a glancing blow. The next morning, the ships were recalled and the cruisers arrived in Scapa Flow that evening to refuel and replenish ammunition.[19]
On 12 April, Captain Herbert Packer assumed command and the ship departed Scapa to rendezvous with the escort for Convoy NP-1 which was loaded with two infantry brigades bound for Narvik, Norway. Prime Minister Winston Churchill decided to take advantage of the unopposed occupation of Namsos on the 14th and ordered that the 146th Infantry Brigade should arrive offshore at dusk on the 15th to reinforce the initial landing force. Layton chose to escort the troopships Empress of Australia and MS Chrobry with Manchester, her half-sister HMS Birmingham (C19), the anti-aircraft cruiser Cairo and three destroyers. The threat of air attack and poor port facilities at Namsos caused the Admiralty to change the destination, but the troops and most of their equipment completed unloading on the 19th. That day the Admiralty ordered most of the ships off Norway home to prepare for further operations so the cruiser headed for Rosyth, Scotland.[20]
Later that day, Manchester was ordered back to the Namsos area to escort Convoy FP-1 back to Britain. On 22 April she returned to Rosyth to begin loading about half of the 15th Infantry Brigade, together with Birmingham and the heavy cruiser York, to be ferried to Åndalsnes and Molde. Manchester disembarked her passengers at the latter town on the 25th and then joined Birmingham to cover three destroyers laying mines near Trondheim. The sisters returned to Scapa Flow on 28 April to refuel. Three days later they arrived at Åndalsnes to evacuate the remaining troops still ashore. Manchester was slightly damaged by splinters from near misses made by the Luftwaffe that were otherwise ineffectual.[21]
On 10 May Manchester and Sheffield were ordered to sea to protect the crippled destroyer Kelly which was being towed home after having been torpedoed by an E-boat. The cruisers engaged Luftwaffe aircraft when they unsuccessfully attacked the next day and then were ordered to return to Rosyth in light of the submarine threat where she began a brief refit. On 26 May, the 18th CS, consisting of Manchester, Birmingham and Sheffield, was transferred to the Humber for anti-invasion duties. They returned to Rosyth on 10 June after the vulnerabilities of Immingham were realised. Layton was relieved by Vice-Admiral Frederick Edward-Collins on 15 June and the ships returned to Immingham on 1 July. Edward-Collins transferred his flag to Birmingham on 4 July after which Manchester sailed to Portsmouth to begin a brief refit. She arrived back in Scapa Flow on 22 August and Edward-Collins immediately returned his flag to the ship. Her stay there was brief as the squadron immediately sailed for Rosyth to resume anti-invasion duties. The squadron returned to Immingham on 3 September as fears of invasion rose. Edward-Collins was relieved by Vice-Admiral Lancelot Holland on 12 November.[22]
On 15 November the ship departed Scapa Flow to rendezvous with a convoy that conveying RAF personnel and equipment to Alexandria, Egypt. After their arrival in Gibraltar on 21 November, Manchester and Southampton loaded roughly 1,400 men and many tons of supplies and departed on the 25th, escorted by Force H. They were to be met by ships of the Mediterranean Fleet south of Sardinia, Italy, the whole affair codenamed Operation Collar. The Italians spotted the convoy and attempted to intercept it on 27 November in the Battle of Cape Spartivento. The British concentrated their cruisers, even though the efficiency of Manchester and Southampton was reduced by their passengers, and engaged their Italian counterparts at long range with little effect. The Italians attempted to disengage, but the British pursued until they risked leaving the convoy unprotected. The subsequent aerial attacks by the Regia Aeronautica (Royal Italian Airforce) failed to damage any British ships. During the battle, Manchester fired 912 shells from her main guns without making a single hit. But she was hit by the Italian battleship Vittorio Veneto causing splinter damage.[23] The ship arrived at Alexandria without further incident on 30 November. She passed through the Mediterranean at high speed without being spotted and arrived at Scapa Flow on 13 December. Holland transferred his flag to her half-sister Edinburgh on 8 January 1941. The cruiser began a lengthy refit at Jarrow on 11 January that lasted until 17 April.[24]
1941
Manchester rejoined the 18th CS at Scapa Flow the following day and spent the rest of the month working up. On 18 May the cruiser and Birmingham were ordered to patrol the Iceland-Faroe Islands gap, but they played no part in the search for the Bismarck as they were repositioned north of Iceland in case the German ships attempted to return to Germany through the Denmark Strait after the battlecruiser Hood was sunk on 24 May. The ships returned to Scapa Flow on 3 June and Packer was relieved by Captain Harold Drew. Manchester sailed on 9 June to Hvalfjord, Iceland, to patrol the Denmark Strait for the rest of the month, returning to Scapa on 3 July.[25]
The ship joined the escort force for Convoy WS-9C bound for Gibraltar on 12 July and arrived there eight days later where she loaded troops and supplies from the convoy to be conveyed to Malta in Operation Substance. The convoy came together on 23 July and the Italians determined that it was bound for Malta. The ships of the Regia Marina (Royal Italian Navy) were not prepared to attack so that was left to the bombers of the Regia Aeronautica. During the first attack that morning Manchester was hit by an Italian aerial torpedo that struck abreast 'X' turret. It blew a 60-foot-long (18.3 m) hole in the hull, disabled both portside propeller shafts, and allowed heavy flooding that caused a 12.5-degree list. The estimated 2,000 long tons (2,032 t) of water also caused the ship to trim down at the stern by 7 feet 6 inches (2.3 m) and filled the aft engine room which meant that only a single propeller shaft was operable. The detonation killed 3 officers and 23 ratings from Manchester's crew and 5 officers and 7 other ranks from the embarked troops. The list was corrected less than three hours after the attack and the cruiser was ordered to return to Gibraltar, escorted by a destroyer. The two ships were unsuccessfully attacked by more Italian bombers later that day and reached their destination on the 26th.[26]
Temporary repairs took until 15 September when the ship then sailed for the Philadelphia Navy Yard in the United States for permanent repairs. This was finished on 27 February 1942, after which she returned to Portsmouth, where final work was completed by the end of April. On her return to service she rejoined the Home Fleet at Scapa Flow on 4 May, spending most of the rest of the month working up. Manchester covered a minelaying operation in the Denmark Strait on 29 May–1 June before returning to Scapa on 4 June. Two days later, King George VI visited the ship during his visit to Scapa. The cruiser spent most of the next two weeks exercising with the other ships of the Home Fleet. On 19 June, Vice-Admiral Stuart Bonham Carter, commander of the 18th CS, hoisted his flag aboard Manchester. On 30 June–2 July, the ship ferried supplies and reinforcements to Spitzbergen Island in the Arctic Ocean. Immediately thereafter, she helped to provide distant cover for Convoy PQ 17 for the next two days. Upon her return to Scapa, she became a private ship when Bonham Carter struck his flag.[27]
Operation Pedestal
Main article: Operation Pedestal
Operation Pedestal, 11 August: A general view of the convoy under air attack showing the intense anti-aircraft barrage put up by the escorts. The battleship Rodney is on the left and Manchester is on the right.
Manchester was transferred to the 10th CS in preparation for Operation Pedestal, another convoy to resupply the besieged island of Malta. She departed Greenock on 4 August, part of the escort for the aircraft carrier Furious. They joined the main body of the convoy on the 7th off the coast of Portugal. The cruiser refuelled at Gibraltar and rejoined Force X, the convoy's close escort, on 10 August. Later that day, Eagle was sunk by a German submarine, the first casualty of many suffered by the convoy. By the night of 13/14 August, Force X was passing through the mine-free channel close off the Tunisian coast. At 00:40 the convoy was attacked by a pair of German S-boats, but they were driven off, with one boat damaged by British fire. About 20 minutes later Manchester was attacked near Kelibia by a pair of Italian MS boats (MTBs), MS 16 and MS 22, which each fired one torpedo, one of which struck the cruiser in the aft engine room, despite her efforts to evade the torpedoes, and jamming her rudder hard to starboard. The hit killed one officer and nine ratings and knocked out electrical power to the aft end of the ship. She slowed to a stop as both starboard propeller shafts were damaged and flooding of the aft engine room disabled both inner shafts. Only the port outer shaft was operable, but its turbine had temporarily lost steam due to the explosion.[28]
The flooding quickly caused Manchester to take on an 11-degree list and both the main radio room and the four-inch magazine to fill with water. At about 01:40 Drew ordered "Emergency Stations" which was a standing order when not already at action stations that required all crewmen not required to operate or supply the anti-aircraft guns to proceed to their abandon ship positions. Transferring oil from the starboard fuel tanks to port and jettisoning the starboard torpedoes reduced the list to about 4.5 degrees by 02:45. Drew felt that the ship's tactical situation was dire due to the threat of other motor torpedo boats as the ship's working armament was limited to the four-inch guns and the anti-aircraft weapons. He also felt it imperative that she had to reach deep water by the island of Zembra by dawn (05:30) which he estimated would take about three hours of steaming. The initial damage reports included a two- to three-hour estimate of restoring steam power as the extent of the damage had not yet been fully assessed, although that was repaired much more quickly than the initial estimate. Focused on the tactical situation, Drew was unaware that steam had been restored to the port outer turbine, the rudder unjammed and electrical power had been restored to the steering gear at about 02:02 before he decided to abandon ship 45 minutes later. Earlier, the destroyer Pathfinder had stopped to render assistance at 01:54 and Drew had transferred 172 wounded and superfluous crewmen before she had to depart to rejoin the convoy.[29]
About 02:30 Drew inquired about the necessary preparations for scuttling by her own crew with explosive charges during a conversation with his chief engineer. About 15 minutes later he addressed the crew informing them of his decision to scuttle the cruiser and to prepare to abandon ship. The order to scuttle was given at 02:50 and it was impossible to rescind when the chief engineer informed him that power had been restored to one turbine and the steering gear five minutes later. Manchester finally sank at 06:47. Drew ordered his crew to abandon ship at 03:45; one man drowned as he attempted to swim ashore, but the rest of his men survived. Most made it ashore, but an estimated 60 to 90 men were rescued by the destroyers Somali and Eskimo when they were dispatched at 07:13 to render assistance to the cruiser after Pathfinder met up the rest of the 10th CS. Two other men were rescued by an Italian MTB, but they were ultimately turned over to the French and joined the rest of the crew in the Laghouat prison camp.[30]
Aftermath
The Admiralty convened a Board of Enquiry on 16 September to establish the facts of the cruiser's loss using testimony provided by available witnesses. Rear-Admiral Bernard Rawlings, Assistant Chief of the Naval Staff (Foreign), and the First Sea Lord, Admiral Dudley Pound reviewed the board's findings and believed that Drew's actions showed a lack of determination to fight his ship. Pound further believed that this disqualified Drew from ever again commanding a ship unless further inquiry proved otherwise. First Lord of the Admiralty A. V. Alexander concurred with Pound's comments on 9 October.[31]
The interned crew was released after French North Africa joined Free France and all had arrived back in Britain by 25 November. Drew was ordered to write a report on the loss of his ship five days later by the Admiralty and forwarded his report on 7 December. A week later the Admiralty ordered that a court martial be convened for the loss of Manchester under article 92 of the Naval Discipline Act 1866 (29 & 30 Vict. c. 109) and it began on 2 March 1943.[32]
Drew's written evidence focused on the tactical situation in which he found himself: adrift in a narrow passage between the coast of Tunisia and an off-shore minefield, with the turret ammunition hoists disabled and little four-inch ammunition available and a high expectation of further attacks by MTBs and aircraft if still near the coast by dawn. He believed that any such successful attack would have a high chance of causing Manchester to run aground and fall into enemy hands. The initial damage control report given to him after the torpedo hit estimated three hours to get steam power restored which allowed him only a narrow window to get clear of the coast. His evidence made little mention of "Emergency Stations" and his reasoning behind evacuating unwounded crewmen aboard Pathfinder before ascertaining the full extent of the damage.[33]
After the modern Royal Navy's longest-ever court martial, the court determined that Manchester's damage was remarkably similar to that suffered on 23 July 1941 whilst under his command; that the cruiser was capable of steaming at 10–13 knots (19–24 km/h; 12–15 mph) on her port outer propeller shaft, that her main and secondary armament was largely intact, and that the initial list of 10–11 degrees had been considerably reduced via counter-flooding, jettisoning her torpedoes, and transfers of fuel oil. Drew was "dismissed his ship", severely reprimanded, and was prohibited from further command at sea; four other officers and a petty officer were also punished.[34]
A diving expedition visited the wreck at a depth of about 80 m (260 ft) in 2002 and footage taken by the divers was used in a TV documentary entitled Running the Gauntlet produced by Crispin Sadler. They discovered that the ship was largely intact, lying on her starboard side. Two of the ship's survivors accompanied the expedition and reminisced about their experiences.[35] Another diving expedition to view Manchester was undertaken in 2009.[36]

HMS Manchester was a Town-class light cruiser built for the Royal Navy in the late 1930s, one of three ships in the Gloucester subclass. Completed in 1938, she was initially deployed with the East Indies Station and had a relatively short but active career. When World War II began in September 1939, the cruiser began escorting convoys in the Indian Ocean until she was ordered home two months later. In late December Manchester began conducting patrols in the Norwegian Sea enforcing the blockade of Germany. Beginning in April 1940 the ship played a minor role in the Norwegian Campaign, mostly escorting convoys. She was assigned to anti-invasion duties in May–November in between refits.
In November the cruiser was tasked to escort a convoy through the Mediterranean and participated in the Battle of Cape Spartivento. Manchester was refitting during most of early 1941, but began patrolling the southern reaches of the Arctic Ocean in May. The cruiser was detached to escort a convoy to Malta in July and she was badly damaged by an aerial torpedo en route. Repairs were not completed until April 1942 and the ship spent the next several months working up and escorting convoys.
Manchester participated in Operation Pedestal, another Malta convoy, in mid-1942; she was torpedoed by two Italian motor torpedo boats and subsequently scuttled by her crew. Casualties were limited to 10 men killed by the torpedo and 1 who drowned as the crew abandoned ship.[Note 1] Most of the crew were interned by the Vichy French when they drifted ashore.

Design and description
The Town-class light cruisers were designed as counters to the Japanese Mogami-class cruisers built during the early 1930s and the last batch of three ships was enlarged to accommodate more fire-control equipment and thicker armour.[2] The Gloucester group of ships were a little larger than the earlier ships of the class and received additional armour.[3] They displaced 9,400 long tons (9,551 t) at standard load and 11,650 long tons (11,837 t) at deep load. The cruisers had an overall length of 591 feet 6 inches (180.3 m), a beam of 62 feet 4 inches (19 m) and a draught of 20 feet 7 inches (6.3 m).[4] They were powered by four Parsons geared steam turbine sets, each driving one shaft using steam provided by four Admiralty 3-drum boilers. The turbines developed a total of 82,500 shaft horsepower (61,500 kW) and were designed to give a maximum speed of 32 knots (59 km/h; 37 mph).[5] During her sea trials on 28 March – 7 April 1938, Manchester achieved an average speed of 32.6 knots (60.4 km/h; 37.5 mph) from 84,461 shp (62,983 kW).[6] The ships carried enough fuel oil to give them a range of 6,000 nautical miles (11,000 km; 6,900 mi) at 14 knots (26 km/h; 16 mph). The ship's complement was 800–815 officers and ratings.[5]
The Town-class ships mounted twelve BL six-inch (152 mm) Mk XXIII guns in four triple-gun turrets, one superfiring pair each fore and aft of the superstructure. The turrets were designated 'A', 'B', 'X' and 'Y' from front to rear. Their secondary armament consisted of eight QF four-inch (102 mm) Mk XVI dual-purpose guns in twin mounts. Their light anti-aircraft armament consisted of a pair of quadruple mounts for the two-pounder (40-millimetre (1.6 in)) ("pom-pom") anti-aircraft (AA) guns and two quadruple mounts for 0.5-inch (12.7 mm) Vickers AA machine guns. The ships carried two above-water, triple mounts for 21-inch (533 mm) torpedoes.[7] The Towns lacked a full-length waterline armour belt, although the sides of the Gloucester group's boiler and engine rooms and the sides of the magazines were protected by 4.5 inches (114 mm) of armour.[7] The top of the magazines and the machinery spaces were protected by 1.25–2 inches (32–51 mm) of armour. The armour plates on the main-gun turrets had a thickness of 2–4 inches.[3]
The cruisers were designed to handle three Supermarine Walrus amphibious reconnaissance aircraft, one on the fixed D1H catapult and the others in the two hangars abreast the forward funnel, but only two were ever carried in service. A pair of 15,000-pound (6,800 kg) cranes were fitted to handle the aircraft and the ships' boats.[8]
Modifications
When Manchester returned home in November 1939, she was refitted with degaussing equipment and probably had her aft high-angle director-control tower (DCT) fitted. During a brief refit in November 1940, the ship was probably equipped with a Type 286 search radar. During a longer refit in January–March 1941, Manchester's hull was reinforced and her Vickers machine guns were exchanged for an ex-Army 40-millimeter Bofors AA gun atop 'B' turret and five 20-millimetre (0.8 in) Oerlikon AA guns. A Type 284 gunnery radar was installed on the roof of the main armament DCT atop the bridge during this refit. Additional splinter plating to protect the secondary armament and torpedo tubes was probably added at this time, as was an ASDIC sonar system.[9]
Two additional ex-Army Bofors guns reinforced the ship's anti-aircraft suite before she participated in Operation Substance in June 1941. Manchester was torpedoed during this convoy escort mission and while she was being repaired in the United States and Britain, she received three more Oerlikon guns for a total of eight weapons, six of which were positioned in the superstructure, one on the roof of 'X' turret and one on the quarterdeck. Two more ex-Army Bofors guns were added amidships before the ship participated in Operation Pedestal in August 1942. When the repairs were completed in April 1942, her radar suite consisted of a Type 279 early-warning radar, the Type 284 system for her main armament, two Type 285 gunnery radars for the four-inch guns, a Type 273 surface-search radar to replace the Type 286 and probably a pair of Type 282 gunnery radars for the "pom-pom" directors.[10]
Construction and career
Manchester, the first ship of her name to serve in the Royal Navy,[11] was ordered on 23 October 1935 from Hawthorn Leslie and Company. The ship was laid down at their Hebburn shipyard on 28 March 1936 and was launched on 12 April 1937 by the wife of Joseph Toole, the Lord Mayor of Manchester. She was commissioned on 4 August 1938 and departed for her first duty assignment with the 4th Cruiser Squadron in the East Indies on 24 September.[12]
After arriving in the British Colony of Aden, Yemen, on 12 October, Manchester was met by the heavy cruiser Norfolk, the station flagship, and the two ships proceeded to Bombay, British India, and then to Trincomalee, British Ceylon by the end of the month where they spent the next month working up. They spent the next month making port visits on the western coast of British India before returning to Ceylon for a maintenance period in Colombo's dockyard. Ports along the Bay of Bengal were visited in February–March 1939, before the two cruisers arrived in Singapore in the British Straits Settlements on 13 March. They conducted exercises with the aircraft carrier Eagle, the heavy cruiser Kent and the submarine depot ship Medway off the eastern coast of Malaya for the next several weeks.[13]
Visiting Port Blair in the Andaman Islands en route on 28 March, Manchester arrived at Trincomalee to prepare for a refit in Colombo. Rising tensions in Europe caused the refit to be delayed for a week and her refit was completed in early June. She began a tour of Indian Ocean ports on 6 June, supporting an aeronautical survey in Diego Garcia three days later with fuel and supplies before arriving in the British Protectorate of Zanzibar on 20 June. The ship began moving up the African coast until she rendezvoused with her sister ship Gloucester, the new station flagship, at Kilindini Harbour in British Kenya on 14 July. The sisters sailed to Aden when they met the sloops Egret and Fleetwood later that month to practice convoy escort tactics in light of the potential threat posed by Italian colonies on the Red Sea.[14]
Early war service
Manchester had just returned from a patrol in the Red Sea and the Gulf of Aden when Britain declared war on Nazi Germany on 3 September 1939. Together with Gloucester, she sailed for Colombo after refuelling. On 25 September, the ship rendezvoused with the sloop Rochester to help escort an Indian troop convoy through the Red Sea. Manchester escorted an Anglo-French convoy there before rendezvousing with the ocean liner RMS Empress of Australia in the Gulf of Suez to escort her to Colombo. The cruiser was ordered home on 10 November and arrived at Malta eight days later, where Vice-Admiral Geoffrey Layton hoisted his flag as commander of the 18th Cruiser Squadron (CS). The ship arrived in HM Dockyard, Portsmouth on the 25th and was docked to have storm damage and some other defects repaired.[15]
Her refit was completed on 22 December and she joined the Home Fleet at Scapa Flow two days later. Later that month, Manchester was attached to the Northern Patrol, where she was tasked to enforce the blockade of Germany, searching for German blockade runners and contraband material. On 21 February 1940 the ship helped to capture the 4,709-gross register ton (GRT) German merchantman Wahehe.[16] She remained on this duty until early April, although the cruiser was in Scapa Flow when it was attacked by German aircraft on 16 March. Manchester's gunners were unprepared for the attack and her shells were ineffectual.[17]
Norwegian campaign
Main article: Norwegian campaign
The 18th CS was relieved of its attachment to the Northern Patrol and was assigned to escort convoys to and from Norway. On 7 April Manchester, her half-sister Southampton, the anti-aircraft cruiser Calcutta and four destroyers were escorting the 43 ships of Convoy ON-25 bound for Norway. After the Royal Air Force (RAF) reported German ships in the North Sea, the convoy was ordered to turn back and the two light cruisers were to rendezvous with the Home Fleet in the Norwegian Sea. Their orders were later modified to patrol the southern part of the sea. Late on the 8th, the Admiralty ordered the ships to rendezvous with the Home Fleet lest they be caught between the two groups of German ships believed to be at sea; this was accomplished early on the morning of 9 April.[18]
Reinforced by their sisters Sheffield and Glasgow and seven destroyers of the 4th Destroyer Flotilla, the 18th CS was ordered to attack the Königsberg-class cruiser believed to be in Bergen, Norway, later that morning. That afternoon the RAF reported two cruisers in Bergen and the Admiralty cancelled the operation. The Luftwaffe had been tracking the squadron as it approached Bergen and bombers from KG 26 and KG 30 began attacking shortly afterwards. They sank the destroyer Gurkha and near misses damaged Southampton and Glasgow. That night Manchester, Southampton and the 6th Destroyer Flotilla patrolled off Fedjeosen to observe German forces in Bergen and prevent any resupply. The only incident that night was when Manchester spotted a submarine crossing between the two cruisers on the surface; the ship attempted to ram, but only managed a glancing blow. The next morning, the ships were recalled and the cruisers arrived in Scapa Flow that evening to refuel and replenish ammunition.[19]
On 12 April, Captain Herbert Packer assumed command and the ship departed Scapa to rendezvous with the escort for Convoy NP-1 which was loaded with two infantry brigades bound for Narvik, Norway. Prime Minister Winston Churchill decided to take advantage of the unopposed occupation of Namsos on the 14th and ordered that the 146th Infantry Brigade should arrive offshore at dusk on the 15th to reinforce the initial landing force. Layton chose to escort the troopships Empress of Australia and MS Chrobry with Manchester, her half-sister HMS Birmingham (C19), the anti-aircraft cruiser Cairo and three destroyers. The threat of air attack and poor port facilities at Namsos caused the Admiralty to change the destination, but the troops and most of their equipment completed unloading on the 19th. That day the Admiralty ordered most of the ships off Norway home to prepare for further operations so the cruiser headed for Rosyth, Scotland.[20]
Later that day, Manchester was ordered back to the Namsos area to escort Convoy FP-1 back to Britain. On 22 April she returned to Rosyth to begin loading about half of the 15th Infantry Brigade, together with Birmingham and the heavy cruiser York, to be ferried to Åndalsnes and Molde. Manchester disembarked her passengers at the latter town on the 25th and then joined Birmingham to cover three destroyers laying mines near Trondheim. The sisters returned to Scapa Flow on 28 April to refuel. Three days later they arrived at Åndalsnes to evacuate the remaining troops still ashore. Manchester was slightly damaged by splinters from near misses made by the Luftwaffe that were otherwise ineffectual.[21]
On 10 May Manchester and Sheffield were ordered to sea to protect the crippled destroyer Kelly which was being towed home after having been torpedoed by an E-boat. The cruisers engaged Luftwaffe aircraft when they unsuccessfully attacked the next day and then were ordered to return to Rosyth in light of the submarine threat where she began a brief refit. On 26 May, the 18th CS, consisting of Manchester, Birmingham and Sheffield, was transferred to the Humber for anti-invasion duties. They returned to Rosyth on 10 June after the vulnerabilities of Immingham were realised. Layton was relieved by Vice-Admiral Frederick Edward-Collins on 15 June and the ships returned to Immingham on 1 July. Edward-Collins transferred his flag to Birmingham on 4 July after which Manchester sailed to Portsmouth to begin a brief refit. She arrived back in Scapa Flow on 22 August and Edward-Collins immediately returned his flag to the ship. Her stay there was brief as the squadron immediately sailed for Rosyth to resume anti-invasion duties. The squadron returned to Immingham on 3 September as fears of invasion rose. Edward-Collins was relieved by Vice-Admiral Lancelot Holland on 12 November.[22]
On 15 November the ship departed Scapa Flow to rendezvous with a convoy that conveying RAF personnel and equipment to Alexandria, Egypt. After their arrival in Gibraltar on 21 November, Manchester and Southampton loaded roughly 1,400 men and many tons of supplies and departed on the 25th, escorted by Force H. They were to be met by ships of the Mediterranean Fleet south of Sardinia, Italy, the whole affair codenamed Operation Collar. The Italians spotted the convoy and attempted to intercept it on 27 November in the Battle of Cape Spartivento. The British concentrated their cruisers, even though the efficiency of Manchester and Southampton was reduced by their passengers, and engaged their Italian counterparts at long range with little effect. The Italians attempted to disengage, but the British pursued until they risked leaving the convoy unprotected. The subsequent aerial attacks by the Regia Aeronautica (Royal Italian Airforce) failed to damage any British ships. During the battle, Manchester fired 912 shells from her main guns without making a single hit. But she was hit by the Italian battleship Vittorio Veneto causing splinter damage.[23] The ship arrived at Alexandria without further incident on 30 November. She passed through the Mediterranean at high speed without being spotted and arrived at Scapa Flow on 13 December. Holland transferred his flag to her half-sister Edinburgh on 8 January 1941. The cruiser began a lengthy refit at Jarrow on 11 January that lasted until 17 April.[24]
1941
Manchester rejoined the 18th CS at Scapa Flow the following day and spent the rest of the month working up. On 18 May the cruiser and Birmingham were ordered to patrol the Iceland-Faroe Islands gap, but they played no part in the search for the Bismarck as they were repositioned north of Iceland in case the German ships attempted to return to Germany through the Denmark Strait after the battlecruiser Hood was sunk on 24 May. The ships returned to Scapa Flow on 3 June and Packer was relieved by Captain Harold Drew. Manchester sailed on 9 June to Hvalfjord, Iceland, to patrol the Denmark Strait for the rest of the month, returning to Scapa on 3 July.[25]
The ship joined the escort force for Convoy WS-9C bound for Gibraltar on 12 July and arrived there eight days later where she loaded troops and supplies from the convoy to be conveyed to Malta in Operation Substance. The convoy came together on 23 July and the Italians determined that it was bound for Malta. The ships of the Regia Marina (Royal Italian Navy) were not prepared to attack so that was left to the bombers of the Regia Aeronautica. During the first attack that morning Manchester was hit by an Italian aerial torpedo that struck abreast 'X' turret. It blew a 60-foot-long (18.3 m) hole in the hull, disabled both portside propeller shafts, and allowed heavy flooding that caused a 12.5-degree list. The estimated 2,000 long tons (2,032 t) of water also caused the ship to trim down at the stern by 7 feet 6 inches (2.3 m) and filled the aft engine room which meant that only a single propeller shaft was operable. The detonation killed 3 officers and 23 ratings from Manchester's crew and 5 officers and 7 other ranks from the embarked troops. The list was corrected less than three hours after the attack and the cruiser was ordered to return to Gibraltar, escorted by a destroyer. The two ships were unsuccessfully attacked by more Italian bombers later that day and reached their destination on the 26th.[26]
Temporary repairs took until 15 September when the ship then sailed for the Philadelphia Navy Yard in the United States for permanent repairs. This was finished on 27 February 1942, after which she returned to Portsmouth, where final work was completed by the end of April. On her return to service she rejoined the Home Fleet at Scapa Flow on 4 May, spending most of the rest of the month working up. Manchester covered a minelaying operation in the Denmark Strait on 29 May–1 June before returning to Scapa on 4 June. Two days later, King George VI visited the ship during his visit to Scapa. The cruiser spent most of the next two weeks exercising with the other ships of the Home Fleet. On 19 June, Vice-Admiral Stuart Bonham Carter, commander of the 18th CS, hoisted his flag aboard Manchester. On 30 June–2 July, the ship ferried supplies and reinforcements to Spitzbergen Island in the Arctic Ocean. Immediately thereafter, she helped to provide distant cover for Convoy PQ 17 for the next two days. Upon her return to Scapa, she became a private ship when Bonham Carter struck his flag.[27]
Operation Pedestal
Main article: Operation Pedestal
Operation Pedestal, 11 August: A general view of the convoy under air attack showing the intense anti-aircraft barrage put up by the escorts. The battleship Rodney is on the left and Manchester is on the right.
Manchester was transferred to the 10th CS in preparation for Operation Pedestal, another convoy to resupply the besieged island of Malta. She departed Greenock on 4 August, part of the escort for the aircraft carrier Furious. They joined the main body of the convoy on the 7th off the coast of Portugal. The cruiser refuelled at Gibraltar and rejoined Force X, the convoy's close escort, on 10 August. Later that day, Eagle was sunk by a German submarine, the first casualty of many suffered by the convoy. By the night of 13/14 August, Force X was passing through the mine-free channel close off the Tunisian coast. At 00:40 the convoy was attacked by a pair of German S-boats, but they were driven off, with one boat damaged by British fire. About 20 minutes later Manchester was attacked near Kelibia by a pair of Italian MS boats (MTBs), MS 16 and MS 22, which each fired one torpedo, one of which struck the cruiser in the aft engine room, despite her efforts to evade the torpedoes, and jamming her rudder hard to starboard. The hit killed one officer and nine ratings and knocked out electrical power to the aft end of the ship. She slowed to a stop as both starboard propeller shafts were damaged and flooding of the aft engine room disabled both inner shafts. Only the port outer shaft was operable, but its turbine had temporarily lost steam due to the explosion.[28]
The flooding quickly caused Manchester to take on an 11-degree list and both the main radio room and the four-inch magazine to fill with water. At about 01:40 Drew ordered "Emergency Stations" which was a standing order when not already at action stations that required all crewmen not required to operate or supply the anti-aircraft guns to proceed to their abandon ship positions. Transferring oil from the starboard fuel tanks to port and jettisoning the starboard torpedoes reduced the list to about 4.5 degrees by 02:45. Drew felt that the ship's tactical situation was dire due to the threat of other motor torpedo boats as the ship's working armament was limited to the four-inch guns and the anti-aircraft weapons. He also felt it imperative that she had to reach deep water by the island of Zembra by dawn (05:30) which he estimated would take about three hours of steaming. The initial damage reports included a two- to three-hour estimate of restoring steam power as the extent of the damage had not yet been fully assessed, although that was repaired much more quickly than the initial estimate. Focused on the tactical situation, Drew was unaware that steam had been restored to the port outer turbine, the rudder unjammed and electrical power had been restored to the steering gear at about 02:02 before he decided to abandon ship 45 minutes later. Earlier, the destroyer Pathfinder had stopped to render assistance at 01:54 and Drew had transferred 172 wounded and superfluous crewmen before she had to depart to rejoin the convoy.[29]
About 02:30 Drew inquired about the necessary preparations for scuttling by her own crew with explosive charges during a conversation with his chief engineer. About 15 minutes later he addressed the crew informing them of his decision to scuttle the cruiser and to prepare to abandon ship. The order to scuttle was given at 02:50 and it was impossible to rescind when the chief engineer informed him that power had been restored to one turbine and the steering gear five minutes later. Manchester finally sank at 06:47. Drew ordered his crew to abandon ship at 03:45; one man drowned as he attempted to swim ashore, but the rest of his men survived. Most made it ashore, but an estimated 60 to 90 men were rescued by the destroyers Somali and Eskimo when they were dispatched at 07:13 to render assistance to the cruiser after Pathfinder met up the rest of the 10th CS. Two other men were rescued by an Italian MTB, but they were ultimately turned over to the French and joined the rest of the crew in the Laghouat prison camp.[30]
Aftermath
The Admiralty convened a Board of Enquiry on 16 September to establish the facts of the cruiser's loss using testimony provided by available witnesses. Rear-Admiral Bernard Rawlings, Assistant Chief of the Naval Staff (Foreign), and the First Sea Lord, Admiral Dudley Pound reviewed the board's findings and believed that Drew's actions showed a lack of determination to fight his ship. Pound further believed that this disqualified Drew from ever again commanding a ship unless further inquiry proved otherwise. First Lord of the Admiralty A. V. Alexander concurred with Pound's comments on 9 October.[31]
The interned crew was released after French North Africa joined Free France and all had arrived back in Britain by 25 November. Drew was ordered to write a report on the loss of his ship five days later by the Admiralty and forwarded his report on 7 December. A week later the Admiralty ordered that a court martial be convened for the loss of Manchester under article 92 of the Naval Discipline Act 1866 (29 & 30 Vict. c. 109) and it began on 2 March 1943.[32]
Drew's written evidence focused on the tactical situation in which he found himself: adrift in a narrow passage between the coast of Tunisia and an off-shore minefield, with the turret ammunition hoists disabled and little four-inch ammunition available and a high expectation of further attacks by MTBs and aircraft if still near the coast by dawn. He believed that any such successful attack would have a high chance of causing Manchester to run aground and fall into enemy hands. The initial damage control report given to him after the torpedo hit estimated three hours to get steam power restored which allowed him only a narrow window to get clear of the coast. His evidence made little mention of "Emergency Stations" and his reasoning behind evacuating unwounded crewmen aboard Pathfinder before ascertaining the full extent of the damage.[33]
After the modern Royal Navy's longest-ever court martial, the court determined that Manchester's damage was remarkably similar to that suffered on 23 July 1941 whilst under his command; that the cruiser was capable of steaming at 10–13 knots (19–24 km/h; 12–15 mph) on her port outer propeller shaft, that her main and secondary armament was largely intact, and that the initial list of 10–11 degrees had been considerably reduced via counter-flooding, jettisoning her torpedoes, and transfers of fuel oil. Drew was "dismissed his ship", severely reprimanded, and was prohibited from further command at sea; four other officers and a petty officer were also punished.[34]
A diving expedition visited the wreck at a depth of about 80 m (260 ft) in 2002 and footage taken by the divers was used in a TV documentary entitled Running the Gauntlet produced by Crispin Sadler. They discovered that the ship was largely intact, lying on her starboard side. Two of the ship's survivors accompanied the expedition and reminisced about their experiences.[35] Another diving expedition to view Manchester was undertaken in 2009.[36]

Did a show Sunday ran Zwarte Zee it's rather short as a member wanted to run his high speed boat.

Just a simple model I built for my son about 14yrs ago. He wasn't interested (more into computers) so I use it for the salt water. Just a brass shaft and 12v high speed 380 motor, runs quite well. Ran it to try out the new 4K camera, (set on 1920x1080) but had to convert the vid from MOV to MP4 to edit it, so it reduced the clarity a bit. At least it doesn't have a blurry bit in the middle of the lens like my 10yr old one. have to figure out a better way, (or get a better editor)

This might be clearer

I wanted to try the driveshaft brake I'd recently fitted and thought I might as well do it on an actual ramp. This ramp has around a 30deg slope so it was a good spot for a test. Tried it with just the trailer first, (don't want my boat model disappearing down the ramp at high speed) and it worked well. I've done another vid where I but a 3kg water bottle on the trailer to simulate the weight of the boat, and that also worked well (although it's a bit scary when 13lbs starts rolling down the ramp backwards.

Lost the trailer a few times going over a big join in the ramp ( forgot the tow ball lock nut) so had a few goes to get it right. I was surprised how well a piece of string round the driveshaft could hold that weight so easily. Only negative is that it's not as good in forward, (would need another wound the opposite hand on the shaft) but that's not as important as reverse control. Still waiting for the weather and tides so I can try another launch. This ramp's not bad, but a little rough !

Made a few adjustments, including alloy braces for the motor pylon (was a bit flexible and I think it was twisting slightly under power. Rudder linkages still need tightening up (crappy HK clevises,-probably will fit ball links) but it was a bit better this time (apart from a high speed excursion into the rushes at the end,-no damage, got in the shadow and brain couldn't calculate time, angle and distance😁) Battery was down to 7.5v/cell after all this (4000mAh 3s) so not a bad run time. Only had full throttle for about 3 secs total, -too hairy!😁 Put in expo and dual rates but that didn't do much (too much rudder slop to be accurate). Back to the mod shop.

💡Scratch built from plans. Plank on frame. Large brushless motor,150 amp esc,length is54 inches custom made propshaft ballraced at each end and middle. Has running lights,and large very bright searchlight. Flack Mats were made by better Half. Everything else was scratch built by myself.

Boat is Scratch built 36" British Power Boat 64ft High Speed ASR Launch which belonged to the RNZAF. The launch was one of the 22 built and was shipped to NZ in 1940. it was the only one of its type in the Southern Hemisphere. Model has twin motors, ESCs, sound units etc. Has remotely switched water pump for water cooled brushless 2000kv in runner motors and remotely switched lighting. Uses 2x 2200mah 2s LiPos for drive and 1 1800mah LiPo for the pump (also a separate battery for the LED lights. Boat is built with strip planked balsa on ply frame and fiber glassed. Deck is ply, wheelhouse is varnished balsa. The colour is as it was for most of its time in the RNZAF . Took about 5 years on and off to build and finished it last year. (please ignore the time date - can't get rid of it .

Been flying planes for many years and never thought to try boats until very recently. Just tried out the Feilun FT-011 and thought it was awesome for a first time single hull boat. Fairly quick, good run time and the fact that it will self right if it flips is a big bonus. Could not flip it myself despite some full speed tight turns but think it probably would if jumped some waves. You would expect for a relatively cheap outfit that the seals might not be perfect but after the first run there was virtually no water inside. 5.5 minute running time as well which seems decent for a 4S2200 pack. Really enjoyed it and looking forward to taking it out on the water again soon. Filmed with the Panasonic AG-UX180 4K Pro camcorder.

Having reviewed many planes, quads and cars over the last 3 years so it was refreshing to get a boat in the water. Why didn't I do this a long time ago? Bit addictive to say the least. Was surprised how quick this thing was on 3 cells. Lots of tight turns and no hint of it tipping. And a good run time not far off the manufacturers stated 8 minutes. Balance seemed to be quite critical though. The stock 3S2500 in the battery holder had it on step from the go. I dropped in a 3S2200 and despite pushing it to the furthest forward point it would bog down when it lost momentum. Easily solved with a little lead on some velcro next time out. Otherwise really impressed. Zero time to set it up. Nice it has rates dial for steering on the transmitter so can go between hooligan style tight turns and smooth high speed turns. Looking forward to taking it out again.

Standard wood drills (as in this photograph) work well for cutting neat, point centralised plastic-card port holes, as good as they do for wood or MFD etc. (instead of high-speed steel drills, which can end up a mess).

For clear plastic glazing to match these ports. I use circular punch's which cut neat clear round plastic glazing to fit, also for cutting round plastic-card for circular objects etc. I have found that it works better if punched with a hard hammer tap onto a flat hard-wood backing.
