The end of World War II in Europe occurred in May 1945. Following the suicide of Adolf Hitler on 30 April, leadership of Nazi Germany passed to Grand Admiral Karl Dönitz and the Flensburg Government. Soviet troops conquered Berlin on 2 May, and a number of German military forces surrendered over the next few days. On 8 May, Field Marshal Wilhelm Keitel signed the German Instrument of Surrender, an unconditional surrender to the Allies, in Karlshorst, Berlin. This is celebrated as Victory in Europe Day, while in Russia 9 May is celebrated as Victory Day. Some fighting continued after the German surrender. Some battles continued on the Eastern Front such as the Courland Pocket in western Latvia surrendering on 10 May, and the Prague offensive in Czechoslovakia ending on 11 May. On 25 May 1945, the Battle of Odžak ended in a Yugoslav Partisan victory. Following the conclusion in the European theatre, the war continued in the Pacific theatre.
