During World War II, U-boat warfare was the major component of the Battle of the Atlantic, which lasted the duration of the war. Germany had the largest submarine fleet in World War II, since the Treaty of Versailles had limited the surface navy of Germany to six battleships (of less than 10,000 tons each), six cruisers and 12 destroyers.[5] Prime Minister Winston Churchill wrote "The only thing that really frightened me during the war was the U-Boat peril".

U-boat Pens in Saint-Nazaire, FranceIn the early stages of the war, the U-boats were extremely effective in destroying Allied shipping, initially in the mid-Atlantic, where neither Canadian nor British based escorts provided cover. There was an extensive trade in war supplies and food across the Atlantic, which was critical for Britain's survival. This continuous action became known as the Battle of the Atlantic, as the British developed technical defences such as ASDIC and RADAR, and the German U-Boats responded by hunting in what was called "wolf packs" where multiple submarines would stay close together making it easier for them to sink a specific target. Later, when the USA entered the war, the U-boats ranged from the Atlantic coast of the United States and Canada to the Gulf of Mexico, and from the Arctic to the west and southern African coasts and even as far east as Penang. It is even rumored that one German U-boat managed to make it all the way down to Galveston Bay, Texas. The U.S. military engaged in various tactics against German incursions in the Americas, these included military surveillance of foreign nations in Latin America, particularly in the Caribbean, in order to deter any local governments from supplying German U-boats.

Because speed and range were severely limited underwater while running on battery power, U-boats were required to spend most of their time surfaced running on diesel engines, diving only when attacked or for rare daytime torpedo strikes. The most common U-boat attack during the early years of the war was conducted on the surface and at night, see Submarine warfare. This period, before the Allied forces developed truly effective antisubmarine warfare (ASW) tactics, was referred to by German submariners as "die glückliche Zeit" or "the happy time."[6]
