Operation Spring Awakening
With the exception of Operation Spring Awakening ("Unternehmen Frühlingserwachen"), which was launched in March 1945, the siege of Budapest was the last major operation on the southern front for the Germans. The siege further depleted the "Wehrmacht" and especially the "Waffen-SS". For the Soviet troops, the siege of Budapest was a final rehearsal before the Battle of Berlin. It also allowed the Soviets to launch the Vienna Offensive. On 13 April 1945, exactly two months after the surrender of Budapest, Vienna fell.
