Wiener Operation
On 22 March, the Red Army encirclement of the "Totenkopf" and "Wiking" was almost complete. The 9th SS Panzer Division Hohenstaufen held open a route which could be used to withdraw – the Berhida Corridor – and Gille's corps escaped the encirclement. The Red Army then launched the Vienna Offensive which destroyed any resemblance of an organised German line of defence. The remnants of the division retreated into Czechoslovakia where it surrendered to the American forces on 9 May.
