Newfoundland Escort Force
Newfoundland Escort Force (NEF) was a Second World War naval command created on 20 May 1941 as part of the Allied convoy system in the Battle of the Atlantic. Created in response to the movement of German U-boats into the western Atlantic Ocean, the Newfoundland Escort Force (NEF) was instituted to cover the convoy escort gap that existed between the local convoy escort in Canada and the United Kingdom. The Royal Canadian Navy provided the majority of naval vessels to the NEF along with its commander Commodore Leonard W. Murray, with units from the British, Norwegian, Polish, French and Dutch navies also assigned. The NEF was reconstituted as part of the Mid-Ocean Escort Force in 1942. Background The adoption of wolfpack and motor torpedo boat tactics solved two problems the U-boat fleet had against the convoy system the Allies had adopted. Locating the convoy and then setting up a concerted attack. The German adoption of these tactics forced the Allies to alter thei ...

Naval Fleet
A fleet or naval fleet is a large formation of warships – the largest formation in any navy – controlled by one leader. A fleet at sea is the direct equivalent of an army on land. Purpose In the modern sense, fleets are usually, but not necessarily, permanent formations and are generally assigned to a particular ocean or sea. Most fleets are named after that ocean or sea, but the convention in the United States Navy is to use numbers. A fleet is typically commanded by an admiral, who is often also a commander in chief. Still, many fleets have been or are commanded by vice admirals or rear admirals. Most fleets are divided into several squadrons, each under a subordinate admiral. Those squadrons, in turn, are often divided into divisions. In the Age of Sail, Royal Navy fleets were divided into van, center, and rear squadrons, named after each squadron's place in the line of battle. In more modern times, the squadrons are typically composed of homogeneous groups of t ...

Wolfpack (naval Tactic)
The wolfpack was a convoy attack tactic employed in the Second World War. It was used principally by the U-boats of the during the Battle of the Atlantic, and by the submarines of the United States Navy in the Pacific War. The idea of a co-ordinated submarine attack on convoys had been proposed during the First World War but had had no success. In the Atlantic during the Second World War, the Germans had considerable successes with their wolfpack attacks but were ultimately defeated by the Allies. In the Pacific, the American submarine force was able to devastate Japan’s merchant marine, though this was not solely due to the wolfpack tactic. Wolfpacks fell out of use during the Cold War as the role of the submarine changed and as convoys became rare. World War I During the (German war on trade) Allies of World War I, Allied ships travelled independently prior to the introduction of the convoy system and were vulnerable to attacks by U-boats operating as 'lone wolves'.

HX Convoys
HX convoys were transatlantic convoys in the North Atlantic during the First World War and in the Battle of the Atlantic in the Second World War. HX convoys sailed eastwards from Halifax, Nova Scotia in Canada, to Liverpool and other ports in Britain. They rendezvoused with BHX convoys from Bermuda ''en route''. After the United States entered the war, HX convoys began at New York. The HX series consisted of 377 convoys, with 17,744 ships. Thirty-eight convoys were attacked (about 10 per cent), with the loss of 110 ships in convoy; sixty stragglers were sunk and 36 lost while detached or after dispersal, with losses from marine accident and other causes, for a total loss of 206 ships or about 1 per cent of the total. Background An HX series had run in the Atlantic Campaign of the First World War in 1917 and 1918. HX convoys were revived in 1939 at the beginning of the Battle of the Atlantic and were run until the end, the longest continuous series of the war. HX 1 sailed on 16 ...

ON Convoys
The ON and later ONS convoys were a series of North Atlantic trade convoys running Outbound from the British Isles to North America during the Atlantic campaign of the Second World War. The ON convoys replaced the earlier OA/OB series of outbound convoys in July 1941 and ran until the end of the campaign in May 1945. They were organized as alternating fast and slow convoys until March 1943, when the ONS series was begun to take over the slow trans-Atlantic traffic, after which all in the ON series were fast. ON convoys From 7 September 1939, shortly after the outbreak of the Second World War, all traffic outbound from Britain was organized into the OA and OB series, sailing from London via the English Channel (OA) and from Liverpool via St Georges Channel (OB) into the South-Western Approaches. These would be escorted until beyond the range of U-boat patrols before the ships dispersed to reach their destinations. After the fall of France in June 1940 these were successively reor ...

Sloop-of-war
During the 18th and 19th centuries, a sloop-of-war was a warship of the Royal Navy with a single gun deck that carried up to 18 guns. The rating system of the Royal Navy covered all vessels with 20 or more guns; thus, the term encompassed all unrated warships, including List of gun-brigs of the Royal Navy, gun-brigs and Cutter (boat), cutters. In technical terms, even the more specialised bomb vessels and fire ships were classed by the Royal Navy as sloops-of-war, and in practice these were employed in the role of a sloop-of-war when not carrying out their specialised functions. In World War I and World War II, the Royal Navy reused the term "sloop" for specialised convoy-defence vessels, including the of the First World War and the highly successful of the Second World War, with anti-aircraft and anti-submarine capabilities. They performed similar duties to the destroyer escorts of the United States Navy, and also performed similar duties to the smaller corvettes of the Royal ...

Destroyer
In naval terminology, a destroyer is a fast, maneuverable, long-endurance warship intended to escort larger vessels in a fleet, convoy, or carrier battle group and defend them against a wide range of general threats. They were conceived in 1885 by Fernando Villaamil for the Spanish NavySmith, Charles Edgar: ''A short history of naval and marine engineering.'' Babcock & Wilcox, ltd. at the University Press, 1937, page 263 as a defense against torpedo boats, and by the time of the Russo-Japanese War in 1904, these "torpedo boat destroyers" (TBDs) were "large, swift, and powerfully armed torpedo boats designed to destroy other torpedo boats". Although the term "destroyer" had been used interchangeably with "TBD" and "torpedo boat destroyer" by navies since 1892, the term "torpedo boat destroyer" had been generally shortened to simply "destroyer" by nearly all navies by the First World War. Before World War II, destroyers were light vessels with little endurance for unatte ...

Grand Banks Of Newfoundland
The Grand Banks of Newfoundland are a series of underwater plateaus south-east of the island of Newfoundland on the North American continental shelf. The Grand Banks are one of the world's richest fishing grounds, supporting Atlantic cod, swordfish, haddock and capelin, as well as shellfish, seabirds and sea mammals. Significance The Grand Banks of Newfoundland are a group of underwater plateaus south-east of Newfoundland on the North American continental shelf. These areas are relatively shallow, ranging from in depth. The cold Labrador Current mixes with the warm waters of the Gulf Stream here, often causing extreme foggy conditions. The mixing of these waters and the shape of the ocean bottom lifts nutrients to the surface. These conditions helped to create one of the richest fishing grounds in the world. Fish species include Atlantic cod, swordfish, haddock and capelin; shellfish include scallop and lobster. The area also supports large colonies of seabirds such ...
