The ships departed from Liverpool on 14 February 1942 with convoy rescue ship ''Toward'', and were escorted to the Mid-Ocean Meeting Point by escort group B4.

Murdaugh, USN, was the senior officer of the escort group. The escort group had never operated together before. ''Bernadou'' had been modified for long range escort work by replacing the fourth boiler and stack with an extra fuel tank. ''Nicholson'' had the only functional radar, though the merchant ship ''Toward'' could provide support with its High-frequency direction finding (HF/DF) set. ''Lea'' carried a British ASV aircra ...

Battle Of The Atlantic
The Battle of the Atlantic, the longest continuous military campaign in World War II, ran from 1939 to the defeat of Nazi Germany in 1945, covering a major part of the naval history of World War II. At its core was the Allies of World War II, Allied naval Blockade of Germany (1939–1945), blockade of Germany, announced the day after the declaration of war, and Germany's subsequent counter-blockade. The campaign peaked from mid-1940 through to the end of 1943. The Battle of the Atlantic pitted U-boats and other warships of the German ''Kriegsmarine'' (Navy) and aircraft of the ''Luftwaffe'' (Air Force) against the Royal Navy, Royal Canadian Navy, United States Navy, and World War II United States Merchant Navy, Allied merchant shipping. Convoys, coming mainly from North America and predominantly going to the United Kingdom and the Soviet Union, were protected for the most part by the British and Canadian navies and air forces. These forces were aided by ships and aircraft of th ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Radar
Radar is a detection system that uses radio waves to determine the distance ('' ranging''), angle, and radial velocity of objects relative to the site. It can be used to detect aircraft, ships, spacecraft, guided missiles, motor vehicles, weather formations, and terrain. A radar system consists of a transmitter producing electromagnetic waves in the radio or microwaves domain, a transmitting antenna, a receiving antenna (often the same antenna is used for transmitting and receiving) and a receiver and processor to determine properties of the objects. Radio waves (pulsed or continuous) from the transmitter reflect off the objects and return to the receiver, giving information about the objects' locations and speeds. Radar was developed secretly for military use by several countries in the period before and during World War II. A key development was the cavity magnetron in the United Kingdom, which allowed the creation of relatively small systems with sub-meter resolution. Th ...

Order Of The British Empire
The Most Excellent Order of the British Empire is a British order of chivalry, rewarding contributions to the arts and sciences, work with charitable and welfare organisations, and public service outside the civil service.

There is also the related British Empire Medal, whose recipients are affiliated with, but not members of, the order. Recommendations for appointments to the Order of the British Empire were originally made on the nomination of the United Kingdom, the self-governing Dominions of the Empire (later Commonwealth) and the Viceroy of India. Nominations continue today from Commonwealth countries that participate in recommending British honours. Most Commonwealth countries ceas ...

City Of Halifax
A city is a human settlement of notable size.Goodall, B. (1987) ''The Penguin Dictionary of Human Geography''. London: Penguin.Kuper, A. and Kuper, J., eds (1996) ''The Social Science Encyclopedia''. 2nd edition. London: Routledge. It can be defined as a permanent and densely settled place with administratively defined boundaries whose members work primarily on non-agricultural tasks. Cities generally have extensive systems for housing, transportation, sanitation, utilities, land use, production of goods, and communication. Their density facilitates interaction between people, government organisations and businesses, sometimes benefiting different parties in the process, such as improving efficiency of goods and service distribution. Historically, city-dwellers have been a small proportion of humanity overall, but following two centuries of unprecedented and rapid urbanization, more than half of the world population now lives in cities, which has had profound consequences for ...

Dominion Of Newfoundland
Newfoundland was a British dominion in eastern North America, today the modern Canadian province of Newfoundland and Labrador. It was established on 26 September 1907, and confirmed by the Balfour Declaration of 1926 and the Statute of Westminster of 1931. It included the island of Newfoundland, and Labrador on the continental mainland. Newfoundland was one of the original dominions within the meaning of the Balfour Declaration and accordingly enjoyed a constitutional status equivalent to the other dominions of the time. In 1934, Newfoundland became the only dominion to give up its self-governing status, which ended 79 years of self-government. The abolition of self-government came about because of a crisis in Newfoundland's public finances in 1932. Newfoundland had accumulated a significant amount of debt by building a railway across the island, which was completed in the 1890s, and by raising its own regiment during World War I. In November 1932, the government warned th ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Tugboat
A tugboat or tug is a marine vessel that manoeuvres other vessels by pushing or pulling them, with direct contact or a tow line. These boats typically tug ships in circumstances where they cannot or should not move under their own power, such as in crowded harbour or narrow canals, or cannot move at all, such as barges, disabled ships, log rafts, or oil platforms. Some are ocean-going, some are icebreakers or salvage tugs. Early models were powered by steam engines, long ago superseded by diesel engines. Many have deluge gun water jets, which help in firefighting, especially in harbours. Types Seagoing Seagoing tugs (deep-sea tugs or ocean tugboats) fall into four basic categories: #The standard seagoing tug with model bow that tows almost exclusively by way of a wire cable. In some rare cases, such as some USN fleet tugs, a synthetic rope hawser may be used for the tow in the belief that the line can be pulled aboard a disabled ship by the crew owing to its lightn ...

Torpedo Net
Torpedo nets were a passive ship defensive device against torpedoes. They were in common use from the 1890s until the Second World War. They were superseded by the anti-torpedo bulge and torpedo belts. Origins With the introduction of the Whitehead torpedo in 1873, and the subsequent development of the torpedo boat, new means were sought to protect capital ships against underwater attacks. In 1876 the British Admiralty Torpedo Committee came up with a number of recommendations for combating torpedoes, which included "... nets of galvanised iron hung around each battleship from projecting 40 ft spars". Experiments were conducted in 1877, with becoming the first operational ship to be fitted with the nets. Design and use Torpedo nets could be hung out from the defending ship, when moored or otherwise stationary in the water, on multiple horizontal booms. Each boom was fixed to the ship at one end at or below the edge of the main deck, by a steel pin that permitted the boom to b ...
