9 Battle of the Atlantic, Allies: British and American shipping Nazi Germany: U-boats (Unterseeboot or undersea boats, or submarines) attacked the Allied shipping.

10 Battle of the Atlantic,

11 Sept to May 1940 German had success with U-boats (submarines) in WWI. British ships lacked adequate escorts. Hitler avoided attacking ships of neutral nations. The US was officially neutral.

12 June 1940 to March 1941 After Germany defeated France and Norway, the Germans used French and Norwegian ports. German U-boats traveled in “wolf packs” to maximize attacks. Late 1940 was known as “the happy time” for German U-boats.

13 April 1941 to Dec The British added more escorts. The British improved their radar systems. The Americans began assisting the British, but still remained officially neutral. Germans were still commanding the sea.

14 Jan to July 1942 The US entered the war against the Axis Powers (Germany, Japan, Italy). American Navy was preoccupied with the Pacific (Japan), not the Atlantic (Germany). An effective convoy system was not yet in place.

15 Aug to May 1943 American escorting improved. Shipping losses moved away from areas nearest USA. Allied code-breaking and radar improved. Germans could not replace lost U-boats fast enough to keep up.

16 June 1943 to May 1945 After mid-1943, German U-boats became less of a threat. Long-range scout planes improved. The Portuguese allowed the Azores to be used as an Allied airbase. In 1944, the “wolf pack” tactic was abandoned.

The Germans attacked ships bringing supplies from USA to its allies (UK and USSR). How did the Battle of the Atlantic end?
