The Mozambique Channel is an arm of the Indian Ocean located between the Southeast African countries of Madagascar and Mozambique. The channel is about 1,700 km long and 419 km across at its narrowest point, and reaches a depth of 3,292 m (10,801 ft) about 230 km off the coast of Mozambique. A warm current, the Mozambique Current, flows in a southward direction in the channel, leading into the Agulhas Current off the east coast of Southern Africa.
The Battle of the River Plate was fought in the South Atlantic on 13 December 1939 as the first naval battle of the Second World War. The Kriegsmarine heavy cruiser Admiral Graf Spee, commanded by Captain Hans Langsdorff, engaged a Royal Navy squadron, commanded by Commodore Henry Harwood, comprising the light cruisers HMS Ajax, HMS Achilles and the heavy cruiser HMS Exeter.
HMNZS Achilles was a Leander-class light cruiser, the second of five in the class. She served in the Royal New Zealand Navy in the Second World War. She was launched in 1931 for the Royal Navy, loaned to New Zealand in 1936 and transferred to the new Royal New Zealand Navy in 1941. She became famous for her part in the Battle of the River Plate, alongside HMS Ajax and HMS Exeter and notable for being the first Royal Navy cruiser to have fire control radar, with the installation of the New Zealand-made SS1 fire-control radar in June 1940.
The Battle of the River Plate is a 1956 British war film in Technicolor and VistaVision by the writer-director-producer team of Michael Powell and Emeric Pressburger. The film stars John Gregson, Anthony Quayle, Bernard Lee and Peter Finch. It was distributed worldwide by Rank Film Distributors Ltd.
Hans Wilhelm Langsdorff was a German naval officer, most famous for his command of the German pocket battleship Admiral Graf Spee before and during the Battle of the River Plate off the coast of Uruguay in 1939. After the Panzerschiff was unable to escape a pursuing squadron of Royal Navy ships, Langsdorff scuttled his ship. Three days later he died by suicide in his hotel room in Buenos Aires, Argentina.
The Altmark incident was a naval incident of World War II between British destroyers and the German tanker Altmark, which happened on 16–17 February 1940. It took place in what were neutral Norwegian waters. On board the Altmark were roughly 300 Allied prisoners, whose ships had been sunk by the pocket battleship Graf Spee in the Southern Atlantic Ocean.
HMS Exeter was the second and last York-class heavy cruiser built for the Royal Navy during the late 1920s. Aside from a temporary deployment with the Mediterranean Fleet during the Abyssinia Crisis of 1935–1936, she spent the bulk of the 1930s assigned to the Atlantic Fleet or the North America and West Indies Station. When World War II began in September 1939, the cruiser was assigned to patrol South American waters against German commerce raiders. Exeter was one of three British cruisers that fought the German heavy cruiser Admiral Graf Spee, later that year in the Battle of the River Plate. She was severely damaged during the battle, and she was under repair for over a year.
Altmark was a German oil tanker and supply vessel, one of five of a class built between 1937 and 1939. She is best known for her support of the German commerce raider, the "pocket battleship" Admiral Graf Spee and her subsequent involvement in the "Altmark Incident". In 1940 she was renamed Uckermark and used as supply tanker for the battleships Scharnhorst and Gneisenau during Operation Berlin before sailing to Japan on September 1942 as a blockade breaker.
Thor was an auxiliary cruiser of Nazi Germany's Kriegsmarine in World War II, intended for service as a commerce raider. Also known to the Kriegsmarine as Schiff 10; to the Royal Navy she was Raider E. She was named after the Germanic deity Thor.
The Deutschland class was a series of three Panzerschiffe, a form of heavily armed cruiser, built by the Reichsmarine officially in accordance with restrictions imposed by the Treaty of Versailles. The ships of the class, Deutschland, Admiral Scheer, and Admiral Graf Spee, were all stated to displace 10,000 long tons (10,160 t) in accordance with the Treaty, though they actually displaced 10,600 to 12,340 long tons at standard displacement. The design for the ships incorporated several radical innovations, including the first major use of welding in a warship and all-diesel propulsion. Due to their heavy armament of six 28 cm (11 in) guns and lighter weight, the British began referring to the vessels as "pocket battleships". The Deutschland-class ships were initially classified as Panzerschiffe, but the Kriegsmarine reclassified them as heavy cruisers in February 1940.
MV Dunedin Star was a British refrigerated cargo liner. She was built by Cammell Laird and Co in 1935–36 as one of Blue Star Line's Imperial Star-class ships, designed to ship frozen meat from Australia and New Zealand to the UK. The ship served in the Second World War and is distinguished for her role in Operation Halberd to relieve the siege of Malta in September 1941.
SMS Möwe was a merchant raider of the Imperial German Navy which operated against Allied shipping during World War I.
SS Uhenfels was a German-built heavy-lift ship that was launched in 1931 for DDG Hansa. She was captured by the Royal Navy in 1939, two months after the start of the Second World War. The UK Ministry of Shipping renamed her Empire Ability and contracted Elder Dempster Lines to operate her. In 1941 a German U-boat sank her by torpedo.
Jürgen Wattenberg was a German naval officer and U-boat commander during the Second World War. In a successful career spanning just under a year, he sank 14 ships, a total of 82,027 gross register tons (GRT).
Admiral Graf Spee was a Deutschland-class "Panzerschiff", nicknamed a "pocket battleship" by the British, which served with the Kriegsmarine of Nazi Germany during World War II. The vessel was named after World War I Admiral Maximilian von Spee, commander of the East Asia Squadron who fought the battles of Coronel and the Falkland Islands, where he was killed in action. 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 (10,160 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 knots left only a few capital ships in the Anglo-French navies fast enough and powerful enough to sink them.
SS Clement was a British turbine steamship operated by the Alfred Booth and Company from 1934 to 1939 until she was intercepted and sunk by the German pocket battleship Admiral Graf Spee off the east coast of Brazil becoming the first victim of Graf Spee's commerce raiding sortie
MS Africa Shell, was a British coastal oil tanker operated by the Shell Company of East Africa Ltd. The ship's life was short, lasting only a matter of months from her introduction into service in 1939, until she was intercepted and sunk by the German pocket battleship Admiral Graf Spee in the Mozambique Channel, off the coast of Portuguese East Africa, becoming the sixth victim of Graf Spee's commerce raiding sortie.

(Paddy) Dove (1896–1957) was a British merchant navy officer who served as commanding officer of the MV Africa Shell when she was intercepted and sunk by the German pocket battleship Admiral Graf Spee in the Mozambique Channel, off the coast of Portuguese East Africa, becoming the sixth victim of Graf Spee's commerce raiding sortie.
SS Tairoa was a British cargo liner and refrigerated freight ship, operated by the Shaw, Savill & Albion Line from 1920 to 1939, until she was intercepted and sunk by the German pocket battleship, Admiral Graf Spee, off South West Africa, becoming the penultimate victim of Graf Spee's commerce raiding sortie.
SS Mopan was a British steam cargo liner operated by the Fyffes Line from 1929 to 1940 until she was intercepted in mid-Atlantic and sunk by the German pocket battleship Admiral Scheer, becoming the first victim of Admiral Scheer's commerce raiding sortie.
