Battle of Berlin
On 20 April, Hitler's birthday, the allies began to bombard the centre of the city with rockets and artillery.  They did not stop until the city surrendered.  On 22 April, Hitler, when he knew the Germans plans had failed, cried in anger.  He knew the war was as good as lost.  One of his generals, Alfred Jodl, thought it would be possible to form a linkup between the army in Berlin, and the 12th Army commanded by Walther Wenck that were fighting the U.S. Army.  Hitler agreed to this idea, but those troops could not get to the city.
