With the Soviet Vistula–Oder Offensive, launched on 12 January 1945, and the parallel East Prussian Offensive launched on 13 January 1945, Soviet gains of pre-war German and annexed Polish territory became permanent. With the subsequent East Pomeranian, Lower Silesian and Upper Silesian Offensives in February and March, the Red Army seized control of virtually all territories east of the Oder river. Wehrmacht counter-offensives like Operation Solstice and Operation Gemse were repelled, and only shrinking pockets like Breslau, Danzig, Heiligenbeil, Hela, Kolberg, Königsberg, and Pillau remained German controlled. Soviet soldiers committed reprisal rapes and other crimes In most cases, implementation of the evacuation plans was delayed until Soviet and Allied forces had defeated the German forces and advanced into the areas to be evacuated. The responsibility for leaving millions of Germans in these vulnerable areas until combat conditions overwhelmed them can be attributed directly to the draconian measures taken by the German authorities against anyone even suspected of 'defeatist' attitudes [as evacuation was considered] and the fanaticism of many Nazi functionaries in their execution of Hitler's 'no retreat' orders. Hitler and his staff refused to accept Soviet military superiority. Hitler called the Red Army "gleaned punks" and "booty divisions", who were not able to win decisive battles. Himmler called the preparation of the early 1945 Soviet offensive "the biggest bluff since Dshingis Khan".
