Dirlewanger then led his men in joining the efforts to put down the Slovak National Uprising in October 1944, eventually being posted on front lines of Hungary and eastern Germany to fight against the advancing Red Army. In February 1945, the unit was expanded again and re-designated as an SS Grenadier division. That same month, Dirlewanger was shot in the chest while fighting against the Soviet forces near Guben in Brandenburg and sent to the rear. It was his twelfth and final injury in the war. On 22 April, he went into hiding.
