plutot le pont Schulenburger a Spandau?
May 3, 1945
"During an attempt by Obersturmmfuhrer Lippert to make his way west as an infantryman, he was killed by a bullet in the head...."
The above action took place in Spandau as part of a group formed by Major General Mummert. The two King Tigers joined up with this group in time to help with the breakout across the Schulenburger Bridge. The Tigers of Lippert and Schafer drove up to this bridge and provided covering fire. As Lippert and Schafer opened fire the Russian fire died done and the spearhead of this attack was able to cross the bridge.
In a bit of irony, after moving a few hudred meters past the bridge the two King Tigers encountered Russian infantry and tanks, with a JS tank being the main obstruction, Schafer moved to a point to engage this Stalin tank when he received a direct hit from a German 8.8 antiaircraft gun that was captured by the Russians.
Schafer survived but was terribly burned. After many years and a period of temporary blindness, his serious wounds healed and he regained his memory.
