What tactics were used during the Battle of Atlantic?

Answer 1

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.

Answer 2

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.
