German cruiser Admiral Graf Spee

Admiral Graf Spee was a Deutschland-class heavy cruiser (originally termed Panzerschiff or armoured ship, sometimes referred to as "pocket battleship") which served with the Kriegsmarine of Nazi Germany during World War II. The vessel was named after Admiral Maximilian von Spee, commander of the East Asia Squadron that fought the battles of Coronel and Falkland Islands in World War I. She was laid down at the  Reichsmarinewerft  shipyard in Wilhelmshaven in October 1932 and completed by January 1936. The ship was nominally under the 10,000 long tons (10,000 t) limitation on warship size imposed by the Treaty of Versailles, though with a full load displacement of 16,020 long tons (16,280 t), she significantly exceeded it. Armed with six 28 cm (11 in) guns in two triple gun turrets, Admiral Graf Spee and her sisters were designed to outgun any cruiser fast enough to catch them. Their top speed of 28 kn (52 km/h; 32 mph) left only a handful of ships in the Anglo-French navies able to catch them and powerful enough to sink them.[1]

The ship conducted five non-intervention patrols during the Spanish Civil War in 1936–1938, and participated in the Coronation Review for King George VI in May 1937. Admiral Graf Spee was deployed to the South Atlantic in the weeks before the outbreak of World War II, to be positioned in merchant sea lanes once war was declared. Between September and December 1939, the ship sank nine ships totaling 50,089 gross register tons (GRT), before being confronted by three British cruisers at the Battle of the River Plate on 13 December. Admiral Graf Spee inflicted heavy damage on the British ships, but she too was damaged, and was forced to put into port at Montevideo. Convinced by false reports of superior British naval forces approaching his ship, Hans Langsdorff, the commander of the ship, ordered the vessel to be scuttled. The ship was partially broken up in situ, though part of the ship remains visible above the surface of the water. {| class="toc" id="toc"

Construction
Main article: Deutschland class cruiserAdmiral Graf Spee was ordered by the Reichsmarine from the  Reichsmarinewerft  shipyard in Wilhelmshaven.[2] Ordered as Ersatz Braunschweig, Admiral Graf Spee replaced the reserve battleship  Braunschweig . Her keel was laid on 1 October 1932,[3] under construction number 125.[2] The ship was launched on 30 June 1934; at her launching, she was christened by the daughter of Admiral Maximilian von Spee, the ship's namesake.[4] She was completed slightly over a year and a half later on 6 January 1936, the day she was commissioned into the German fleet.[5] Recognition drawing of a Deutschland class cruiserAdmiral Graf Spee was 186 meters (610 ft) long overall and had a beam of 21.65 m (71.0 ft) and a maximum draft of 7.34 m (24.1 ft). The ship had a design displacement of 14,890 t (14,650 long tons; 16,410 short tons) and a full load displacement of 16,020 long tons (16,280 t),[2] though the ship was officially stated to be within the 10,000 long tons (10,000 t) limit of the Treaty of Versailles.[6] Admiral Graf Spee was powered by four sets of MAN 9-cylinder double-acting two-stroke diesel engines. The ship's top speed was 29.5 knots (54.6 km/h; 33.9 mph), at 54,000 shaft horsepower (40,000 kW). At a cruising speed of 20 kn (37 km/h; 23 mph), the ship could steam for 8,900 nautical miles (16,500 km; 10,200 mi). As designed, her standard complement consisted of 33 officers and 586 enlisted men, though after 1935 this was significantly increased to 30 officers and 921–1,040 sailors.[2]

Admiral Graf Spee ' s primary armament was six 28 cm (11.0 in) SK C/28 guns mounted in two triple gun turrets, one forward and one aft of the superstructure. The ship carried a secondary battery of eight 15 cm (5.9 in) SK C/28 guns in single turrets grouped amidships. Her anti-aircraft battery originally consisted of three 8.8 cm (3.5 in) L/45 guns, though in 1935 these were replaced with six 8.8 cm L/78 guns. In 1938, the 8.8 cm guns were removed, and six 10.5 cm (4.1 in) L/65 guns, four 3.7 cm (1.5 in) guns, and ten 2 cm (0.79 in) guns were installed in their place.[2] The ship also carried a pair of quadruple 53.3 cm (21.0 in) deck-mounted torpedo launchers placed on her stern. The ship was equipped with two Arado Ar 196 seaplanes and one catapult. Admiral Graf Spee ' s armored belt was 60 to 80 mm (2.4 to 3.1 in) thick; her upper deck was 17 mm (0.67 in) thick while the main armored deck was 17 to 45 mm (0.67 to 1.8 in) thick. The main battery turrets had 140 mm (5.5 in) thick faces and 80 mm thick sides.[2] Radar consisted of a FMG G(gO) "Seetakt" set;[7] [a] Admiral Graf Spee was the first German warship to be equipped with radar equipment.[8]

Service history
Admiral Graf Spee at Spithead in 1937; HMS Hood and  Resolution  lie in the backgroundAdmiral Graf Spee spent the first three months of her career conducting extensive sea trials to ready the ship for service. The ship's first commander was Kapitän zur See (KzS) Conrad Patzig; he was replaced in 1937 by KzS Walter Warzecha.[4] After joining the fleet, Admiral Graf Spee became the flagship of the German Navy.[9] In the summer of 1936, following the outbreak of the Spanish Civil War, she deployed to the Atlantic to participate in non-intervention patrols off the Republican-held coast of Spain. Between August 1936 and May 1937, the ship conducted three patrols off Spain.<sup class="reference" id="cite_ref-FOOTNOTEWilliamson40_10-0">[10] On the return voyage from Spain, Admiral Graf Spee stopped in Great Britain to represent Germany in the Coronation Review at Spithead for King George VI on 20 May.<sup class="reference" id="cite_ref-FOOTNOTEBidlingmaier73_9-1">[9]

After the conclusion of the Review, Admiral Graf Spee returned to Spain for a fourth non-intervention patrol. Following fleet manoeuvres and a brief visit to Sweden, the ship conducted a fifth and final patrol in February 1938.<sup class="reference" id="cite_ref-FOOTNOTEWilliamson40_10-1">[10] In 1938, KzS Hans Langsdorff took command of the vessel;<sup class="reference" id="cite_ref-FOOTNOTEWilliamson39_3-2">[4] she conducted a series of goodwill visits to various foreign ports throughout the year.<sup class="reference" id="cite_ref-FOOTNOTEWilliamson40_10-2">[10] These included cruises into the Atlantic, where she stopped in Tangier and Vigo.<sup class="reference" id="cite_ref-FOOTNOTEWhitley72_11-0">[11] She also participated in extensive fleet manoeuvres in German waters. She was part of the celebrations for the reintegration of the port of Memel into Germany,<sup class="reference" id="cite_ref-FOOTNOTEWilliamson40_10-3">[10] and a fleet review in honour of Admiral Miklós Horthy, the Regent of Hungary. Between 18 April and 17 May 1939, she conducted another cruise into the Atlantic, stopping in the ports of Ceuta and Lisbon.<sup class="reference" id="cite_ref-FOOTNOTEWhitley72_11-1">[11] On 21 August 1939, Admiral Graf Spee steamed out of Wilhelmshaven, bound for the South Atlantic.<sup class="reference" id="cite_ref-FOOTNOTEBidlingmaier73_9-2">[9]

Following the outbreak of war between Germany and the Allies in September 1939, Adolf Hitler ordered the German Navy to begin commerce raiding against Allied merchant traffic. Hitler nevertheless delayed issuing the order until it became clear that Britain would not countenance a peace treaty following the conquest of Poland. The Admiral Graf Spee was instructed to strictly adhere to prize rules, which required raiders to stop and search ships for contraband before sinking them, and to ensure that their crews are safely evacuated. Langsdorff was ordered to avoid combat, even with inferior opponents, and to frequently change position.<sup class="reference" id="cite_ref-FOOTNOTEBidlingmaier76.E2.80.9377_12-0">[12] On 1 September, the cruiser rendezvoused with her supply ship  Altmark  southwest of the Canary Islands. While replenishing his fuel supplies, Langsdorff ordered superfluous equipment transferred to the Altmark; this included several of the ship's boats, flammable paint, and two of her ten 2 cm anti-aircraft guns, which were installed on the tanker.<sup class="reference" id="cite_ref-FOOTNOTEBidlingmaier77_13-0">[13] Map of the cruises of Admiral Graf Spee and DeutschlandOn 11 September, while still transferring supplies from Altmark, Admiral Graf Spee ' s Arado floatplane spotted the British heavy cruiser HMS Cumberland approaching the two German ships. Langsdorff ordered the two ships to steam off at high speed, successfully evading the British cruiser.<sup class="reference" id="cite_ref-FOOTNOTEBidlingmaier77_13-1">[13] On 26 September, the ship finally received orders authorizing attacks on Allied merchant shipping. Four days later, Admiral Graf Spee ' s Arado located and sank a merchant ship, the steamer Clement; Langsdorff ordered a distress signal sent to the naval station in Pernambuco to ensure the rescue of the ship's crew, which had gone into lifeboats. The British Admiralty immediately issued a warning to merchant shipping that a German surface raider was in the area.<sup class="reference" id="cite_ref-FOOTNOTEBidlingmaier78_14-0">[14]

On 5 October, the British and French navies formed eight groups to hunt down Admiral Graf Spee in the South Atlantic. The British aircraft carriers HMS Hermes,  Eagle , and  Ark Royal  and the French carrier  Béarn , the British battlecruiser  Renown , and French battleships  Dunkerque  and  Strasbourg , and sixteen cruisers were committed to the hunt.<sup class="reference" id="cite_ref-FOOTNOTERohwer6_15-0">[15] Force G, commanded by Commodore Henry Harwood and assigned to the eastern coast of South America, comprised the cruisers Cumberland and  Exeter . Force G was reinforced by the light cruisers  Ajax  and  Achilles ; Harwood detached Cumberland to patrol the area off the Falkland Islands while his other three cruisers patrolled off the River Plate.<sup class="reference" id="cite_ref-FOOTNOTEJackson61.E2.80.9363_16-0">[16]

On the same day as the formation of the Anglo-French hunter groups, Admiral Graf Spee captured the steamer Newton Beech. Two days later, she encountered and sank the merchant ship Ashlea. On 8 October, the following day, she sank Newton Beech,<sup class="reference" id="cite_ref-FOOTNOTEWilliamson40.E2.80.9341_17-0">[17] which Langsdorff had been using to house prisoners.<sup class="reference" id="cite_ref-FOOTNOTEBidlingmaier79_18-0">[18] Newton Beech was too slow to keep up with Admiral Graf Spee, and so the prisoners were transferred to the cruiser. On 10 October, she captured the steamer Huntsman, the captain of which had not sent a distress signal until the last minute, as he had mistakenly identified Admiral Graf Spee as a French warship. Unable to accommodate the crew from Huntsman, Admiral Graf Spee sent the ship to a rendezvous location with a prize crew. On 15 October, Admiral Graf Spee rendezvoused with Altmark to refuel and transfer prisoners; the following morning, the prize Huntsman joined the two ships. The prisoners aboard Huntsman were transferred to Altmark and Langsdorff then sank Huntsman on the night of 17 October.<sup class="reference" id="cite_ref-FOOTNOTEBidlingmaier80_19-0">[19]

On 22 October, Admiral Graf Spee encountered and sank the steamer Trevanion.<sup class="reference" id="cite_ref-FOOTNOTEBidlingmaier41_20-0">[20] At the end of October, Langsdorff sailed his ship into the Indian Ocean south of Madagascar. The purpose of that foray was to divert Allied warships away from the South Atlantic, and to confuse the Allies about his intentions. By this time, Admiral Graf Spee had steamed for almost 30,000 nautical miles (56,000 km; 35,000 mi) and was in dire need of an engine overhaul.<sup class="reference" id="cite_ref-FOOTNOTEBidlingmaier81_21-0">[21] On 15 November, the ship sank the tanker Africa Shell, and the following day, she stopped a Dutch steamer (unnamed), though did not sink her. Admiral Graf Spee returned to the Atlantic between 17 and 26 November to refuel from Altmark.<sup class="reference" id="cite_ref-FOOTNOTERohwer8_22-0">[22] While replenishing supplies, the crew from Admiral Graf Spee built a dummy gun turret on her forecastle and erected a second funnel to alter her silhouette significantly in a bid to confuse allied shipping as to her true identity.<sup class="reference" id="cite_ref-FOOTNOTEBidlingmaier82_23-0">[23]

Admiral Graf Spee ' s Arado floatplane located the merchant ship Doric Star: Langsdorff fired a shot across her bow to stop the ship.<sup class="reference" id="cite_ref-FOOTNOTEBidlingmaier83_24-0">[24] Doric Star was able to send out a distress signal before she was sunk, which prompted Harwood to take his three cruisers to the mouth of the River Plate, which he estimated would be Langsdorff's next target. On the night of 5 December, Admiral Graf Spee sank the steamer Tairoa. The next day, she met with Altmark and transferred 140 prisoners from Doric Star and Tairoa. Admiral Graf Spee encountered her last victim on the evening of 7 December: the freighter Streonshalh. The prize crew recovered secret documents containing shipping route information.<sup class="reference" id="cite_ref-FOOTNOTEBidlingmaier86_25-0">[25] Based on that information, Langsdorff decided to head for the seas off Montevideo. On 11 December, the ship's Arado broke down and could not be repaired, and so it was discarded overboard. The ship's disguise was also removed, in the event that it might hinder the ship in battle.<sup class="reference" id="cite_ref-FOOTNOTEBidlingmaier88_26-0">[26]

Battle of the River Plate
Main article: Battle of the River PlateMap of the manoeuvres of Admiral Graf Spee and the British Royal Navy squadronAt 05:30 on the morning of 13 December 1939, lookouts spotted a pair of masts off the ship's starboard bow. Langsdorff assumed this to be the escort for a convoy mentioned in the documents recovered from Tairoa. At 05:52, however, the ship was identified as HMS Exeter; she was accompanied by a pair of smaller warships, initially thought to be destroyers but quickly identified as Leander class cruisers. Langsdorff decided not to flee from the British ships, and so ordered his ship to battle stations and to steam at maximum speed.<sup class="reference" id="cite_ref-FOOTNOTEBidlingmaier88_26-1">[26] At 06:08, the British spotted Admiral Graf Spee; the force commander, Cmde Henry Harwood, R.N., divided his forces up to split the fire of Admiral Graf Spee ' s 28 cm guns.<sup class="reference" id="cite_ref-FOOTNOTEJackson64_27-0">[27] The German ship opened fire with her main battery at Exeter and her secondary guns at the flagship  Ajax  at 06:17. At 06:20, Exeter returned fire, followed by Ajax at 06:21 and  Achilles  at 06:24. In the span of thirty minutes, Admiral Graf Spee had hit Exeter three times, disabling her two forward turrets, destroying her bridge and her aircraft catapult, and starting major fires. Ajax and Achilles moved closer to Admiral Graf Spee to relieve the pressure on Exeter.<sup class="reference" id="cite_ref-FOOTNOTEBidlingmaier91_28-0">[28]

Langsdorff believed the two light cruisers to be making a torpedo attack, and so he turned away under a smokescreen.<sup class="reference" id="cite_ref-FOOTNOTEBidlingmaier91_28-1">[28] The respite allowed Exeter to withdraw from the action; by now, only one of her gun turrets was still in action, and she had suffered 61 dead and 23 wounded crew members.<sup class="reference" id="cite_ref-FOOTNOTEJackson64_27-1">[27] At around 07:00, Exeter returned to the engagement, firing from her stern turret. Admiral Graf Spee fired on her again, and after scoring more hits, forced Exeter to again withdraw, this time with a list to port. At 07:25, Admiral Graf Spee scored a hit on Ajax that disabled her aft turrets.<sup class="reference" id="cite_ref-FOOTNOTEBidlingmaier91_28-2">[28] Both sides broke off the action, Admiral Graf Spee steaming into the River Plate estuary, while Harwood's battered cruisers remained outside to observe any possible breakout attempts. In the course of the engagement, Admiral Graf Spee had been hit approximately 70 times; 36 men were killed and 60 more were wounded,<sup class="reference" id="cite_ref-FOOTNOTEJackson67_29-0">[29] including Langsdorff, who had been wounded twice by splinters while standing on the open bridge.<sup class="reference" id="cite_ref-FOOTNOTEBidlingmaier91_28-3">[28]

Scuttling
The wreck of Admiral Graf Spee in 1940As a result of battle damage and casualties, Langsdorff decided to put into Montevideo, where repairs could be effected and the wounded men could be evacuated from the ship.<sup class="reference" id="cite_ref-FOOTNOTEJackson67_29-1">[29] Most of the hits scored by the British cruisers caused only minor structural and superficial damage, but the oil purification plant, which was required to prepare the diesel fuel for the engines, was destroyed. Her desalination plant and kitchen were also destroyed, which would have increased the difficulty of a return to Germany. A hit in the bow would also have negatively affected her seaworthiness in the heavy seas of the North Atlantic. In addition, she had significantly depleted her ammunition stocks in the engagement with Harwood's cruisers.<sup class="reference" id="cite_ref-FOOTNOTEWilliamson42_30-0">[30]

After arriving in port, the wounded men were taken to local hospitals and the dead were buried with full military honours. Captive Allied seamen still aboard the ship were released. Repairs necessary to make the ship seaworthy were expected to take up to two weeks.<sup class="reference" id="cite_ref-FOOTNOTEBidlingmaier92_31-0">[31] British naval intelligence worked to convince Langsdorff that vastly superior forces were concentrating to destroy his ship if he attempted to break out of the harbour. The Admiralty broadcast a series of signals on frequencies known to be intercepted by German intelligence. The closest heavy units—the carrier HMS Ark Royal and battlecruiser HMS Renown, were in fact some 2,500 nmi (4,600 km; 2,900 mi) away, much too far to intervene in the situation. Believing the British reports, Langsdorff discussed his options with commanders in Berlin, which were to either break out and seek refuge in Buenos Aires, where the pro-Nazi Argentine government would intern the ship, or to scuttle the ship in the Plate estuary.<sup class="reference" id="cite_ref-FOOTNOTEJackson67_29-2">[29]

Langsdorff was unwilling to risk the lives of his crew, so he therefore decided to scuttle the ship. He was aware that although Uruguay was neutral, the government was on friendly terms with Britain, and if he allowed his ship to be interned, the Uruguayan Navy would allow British intelligence officers access to the ship.<sup class="reference" id="cite_ref-FOOTNOTEWilliamson42_30-1">[30] Neutrality restrictions limited Admiral Graf Spee to a period of 72 hours in Montevideo before she would be interned for the duration of the war.<sup class="reference" id="cite_ref-FOOTNOTEBonner56_32-0">[32] On 17 December 1939, Langsdorff ordered the destruction of all important equipment aboard the ship. The ship's remaining ammunition supply was dispersed throughout the ship in preparation for scuttling. On 18 December, the ship, with only Langsdorff and 40 other men aboard, steamed into the outer roadstead to be scuttled.<sup class="reference" id="cite_ref-FOOTNOTEBidlingmaier93_33-0">[33] A crowd of 20,000 watched as the scuttling charges were set;<sup class="reference" id="cite_ref-FOOTNOTEBonner56_32-1">[32] the crew was taken off by an Argentine tug and the ship was sunk at 20:55.<sup class="reference" id="cite_ref-FOOTNOTEWilliamson43_34-0">[34] The explosions from the munitions sent jets of flame high into the air and created a large cloud of smoke that obscured the ship.<sup class="reference" id="cite_ref-FOOTNOTEBidlingmaier93_33-1">[33] Graf Spee ' s salvaged telemeterOn 20 December, Langsdorff, dressed in full dress uniform and lying on the ship's battle ensign, shot himself.<sup class="reference" id="cite_ref-FOOTNOTEBidlingmaier93_33-2">[33] In late January 1940, the still-neutral American cruiser USS Helena arrived in Montevideo. Her crew was permitted to visit the wreck of Admiral Graf Spee. The Americans met the German crewmen, who were still in Montevideo.<sup class="reference" id="cite_ref-FOOTNOTEBonner56_32-2">[32] In the aftermath of the scuttling, the ship's crew were taken to Argentina, where they were interned for the remainder of the war.<sup class="reference" id="cite_ref-FOOTNOTEBidlingmaier93_33-3">[33] The wreck was partially broken up in situ in 1942–1943, though parts of the ship are still visible to the present;<sup class="reference" id="cite_ref-FOOTNOTEGr.C3.B6ner62_4-1">[5] the wreck lies at a depth of only 11 m (36 ft). In February 2004, a salvage team began work raising the wreck of Admiral Graf Spee. The operation is in part being funded by the government of Uruguay, in part by the private sector, as the wreck is now a hazard to navigation. The first major section—a 27 metric tons (27 long tons; 30 short tons) gunnery range-finding telemeter—was raised on 25 February.<sup class="reference" id="cite_ref-FOOTNOTEBBC_2004-02-26_35-0">[35] On 10 February 2006, the 2 m (6 ft 7 in) eagle figurehead of Admiral Graf Spee was recovered from the stern of the ship.<sup class="reference" id="cite_ref-FOOTNOTEBBC_2006-02-10_36-0">[36]
