During World War II, the Battle of the Atlantic witnessed a staggering series of back-and-forth battles and campaigns from the start of the war in 1939 until 1943, with various tactics utilized by each side. The primary German tactic was 'Wolfpack' submarine attacks: groups of submarines gathered to attack convoys at night in a coordinated fashion. The Allied tactics were based on the convoy-system of defense; however, this basic tactic was supplemented with highly sophisticated intelligence tactics and air-based search-and-destroy (or simple but effective 'air support') tactics that, in the end, proved to be the key to winning the Battle.
During World War II, the Battle of the Atlantic was a back-and-forth maritime battle between naval forces of Germany and their opponents, particularly Great Britain and then (from December 1941 onward) the United States. From 1939 until 1943, the battle witnessed U-boats in "wolfpack" formations on the attack against merchant shipping, anti-submarine task forces chasing down U-boats sighted by radar or airplane spotters, battles between solo airplanes and submarines, a highly sophisticated battle of technology, and also one significant surface-to-surface conflict by capital ships in 1940, among other events. The significant turning-point of this battle came in mid-1943, when Allied superiority in the defense, including technological advances, chased Germany's submarine force out of the Atlantic for good.
