The Western Allied invasion of Germany was coordinated by the Western Allies during the final months of hostilities in the European theatre of World War II. In preparation for the Allied invasion of Germany east of the Rhine, a series of offensive operations were designed to seize and capture the east and west bank of the Rhine: Operation Veritable and Operation Grenade in February 1945, and Operation Lumberjack and Operation Undertone in March 1945, these are considered separate from the invasion of Germany proper, officially designated by the U.S. Army as the Central Europe Campaign. The Allied invasion of Germany east of the Rhine started with the Western Allies crossing the river on 22 March 1945 before fanning out and overrunning all of western Germany from the Baltic in the north to the Alpine passes in the south, where they linked up with troops of the U.S. Fifth Army in Italy. Combined with the capture of Berchtesgaden, any hope of Nazi leadership continuing to wage war from a so-called "National redoubt" or escape through the Alps was crushed, shortly followed by unconditional German surrender on 8 May 1945.
