Sinking of U-864

Date: February 9, 1945 • Location: Fedje, Norway

World War II: Battle of the Atlantic: HMS Venturer sinks U-864 off the coast of Fedje, Norway, in a rare instance of submarine-to-submarine combat.

The Battle of the Atlantic, the longest continuous military campaign in World War II, ran from 1939 to the defeat of Nazi Germany in 1945, covering a major part of the naval history of World War II. At its core was the Allied naval blockade of Germany, announced the day after the declaration of war, and Germany's subsequent counterblockade. The campaign peaked from mid-1940 to the end of 1943.
