The Soviets are preparing the final onslaught to capture Vienna.

We will not sacrifice our men in a hopeless battle, so prepare for a fighting withdrawal.
This will be the last battle for the "Leibstandarte" - fight it the way this elite unit has always done!

Securing your comrades' withdrawal to the American forces in the West is the order of the day.

Remark: The Leibstandarte defended Vienna together with the remainders of other SS-Divisions. 
Obviously, the SS-Divisions wanted to avoid by all means to become Soviet POWs.
