春の目覚め作戦
As most of the German forces in the region were destroyed, troops were rushed in from the Western Front and, in March, the Germans launched the ill-fated Operation Spring Awakening ("Unternehmen Frühlingserwachen") in the Lake Balaton area. The expansive goals of this operation were to protect one of the last oil producing regions available to the Axis and to retake Budapest. Neither goal was achieved.
