Battle of DunkirkThe Battle of Dunkirk (Bataille de Dunkerque) was fought around the French port of Dunkirk (Dunkerque) during the Second World War, between the Allies and Nazi Germany. As the Allies were losing the Battle of France on the Western Front, the Battle of Dunkirk was the defence and evacuation of British and other Allied forces to Britain from 26 May to 4 June 1940. After the Phoney War, the Battle of France began in earnest on 10 May 1940. To the east, the German Army Group B invaded the Netherlands and advanced westward.
Naval mineA naval mine is a self-contained explosive device placed in water to damage or destroy surface ships or submarines. Unlike depth charges, mines are deposited and left to wait until they are triggered by the approach of, or contact with, any vessel or a particular vessel type, akin to anti-infantry or anti-vehicle mines. Naval mines can be used offensively, to hamper enemy shipping movements or lock vessels into a harbour; or defensively, to protect friendly vessels and create "safe" zones.
Bay of BiscayThe Bay of Biscay (ˈbɪskeɪ,_ˈbɪski ), known in Spain as the Gulf of Biscay (Golfo de Vizcaya; Bizkaiko Golkoa), and in France and some border regions as the Gulf of Gascony (Golfe de Gascogne; Golf de Gasconha; Pleg-mor Gwaskogn), is a gulf of the northeast Atlantic Ocean located south of the Celtic Sea. It lies along the western coast of France from Point Penmarc'h to the Spanish border, and along the northern coast of Spain, extending westward to Cape Ortegal.
Deutschland-class cruiserThe Deutschland class was a series of three Panzerschiffe (armored ships), 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, , , and , were all stated to displace in accordance with the Treaty, though they actually displaced 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.
Battle of the Barents SeaThe Battle of the Barents Sea was a World War II naval engagement on 31 December 1942 between warships of the German Navy (Kriegsmarine) and British ships escorting convoy JW 51B to Kola Inlet in the USSR. The action took place in the Barents Sea north of North Cape, Norway. The German raiders' failure to inflict significant losses on the convoy infuriated Hitler, who ordered that German naval strategy would henceforth concentrate on the U-boat fleet rather than surface ships.
High-frequency direction findingHigh-frequency direction finding, usually known by its abbreviation HF/DF or nickname huff-duff, is a type of radio direction finder (RDF) introduced in World War II. High frequency (HF) refers to a radio band that can effectively communicate over long distances; for example, between U-boats and their land-based headquarters. HF/DF was primarily used to catch enemy radios while they transmitted, although it was also used to locate friendly aircraft as a navigation aid.
Canadian Armed ForcesThe Canadian Armed Forces (CAF; Forces armées canadiennes, FAC) are the unified military forces of Canada, including sea, land, and air elements referred to as the Royal Canadian Navy, Canadian Army, and Royal Canadian Air Force. Personnel may belong to either the Regular Force or the Reserve Force, which has four sub-components: the Primary Reserve, Supplementary Reserve, Cadet Organizations Administration and Training Service, and the Canadian Rangers.
Belgian government in exileThe Belgian Government in London (Gouvernement belge à Londres, Belgische regering in Londen), also known as the Pierlot IV Government, was the government in exile of Belgium between October 1940 and September 1944 during World War II. The government was tripartite, involving ministers from the Catholic, Liberal and Labour Parties. After the invasion of Belgium by Nazi Germany in May 1940, the Belgian government, under Prime Minister Hubert Pierlot, fled first to Bordeaux in France and then to London, where it established itself as the only legitimate representation of Belgium to the Allies.
Mark 24 mineThe Mark 24 mine (also known as FIDO or Fido) is an air-dropped anti-submarine weapon (ASW) incorporating passive acoustic homing system and torpedo integration. It was used by the United States, the British and Canadian forces during the Second World War and entered service in March 1943 and remained in use with the US Navy until 1948. Approximately 4,000 torpedoes were produced, with 340 ultimately being deployed during the war. Two-hundred and four torpedoes were launched against submarine targets, with 37 Axis submarines being sunk and a further 18 damaged.
Atlantic pocketsIn World War II, the Atlantic pockets were locations along the coasts of the Netherlands, Belgium and France chosen as strongholds by the occupying German forces, to be defended as long as possible against land attack by the Allies. The locations are known in German as Atlantikfestungen (lit. "Atlantic strongholds") but are known in English as "Atlantic pockets". Six of the Atlantic pockets were captured by the Allies between June and October 1944. Others were placed under siege.
