The Battle of the Atlantic was the longest continuous military campaign in World War II to defeat the Germans in 1945. The British Royal Navy repeated the blockade of Germany of World War II, and Germany repeated its attempt to blockade Britain by using U-boats. The German Navy also tried to use surface warships in the Atlantic Ocean, but lost them in various battles.
