Schneider's records of this battle favour the German side:
"19 April 1944: 18 Tigers support the attack on Isakow, but they erroneously attack to the south in the direction of Podwerbce. Belatedly, some tanks close in on Isakow, preventing enemy forces from escaping to the south. In conjunction with the 101. Jager-Division, which is attacking from the east, the enemy forces are totally destroyed by the Tigers."
The German claims in this engagement remind me of a certain Star Trek episode. The first thing that came to mind was "You look, er, quite well for a man who's been... utterly destroyed, Mr. Spock."
