Torpedo hit forces Lutzow back to port
Thursday, June 12, 1941 www.onwar.com
In the North Atlantic... The German pocket battleship, Lutzow, is damaged by a torpedo attack from a British Beaufort aircraft off the coast of southern Norway. The Lutzow returns to port at Kiel and undergoes repairs until January 1942.
In Germany... The Berlin civil defense authority warns the population to take immediate shelter during air raids because of the danger posed by heavy high-explosive bombs and mines, noting that failure to do so has caused “a great number of bomb victims.”
In London... Allied governments and representatives from the British sponsored European governments in exile pledge mutual assistance and to not conclude any separate peace treaties with the Axis alliance.
Stalin isn't fooled by this British attempt to cause trouble between him and Hitler. :)
