At first, the Dachau SS killed outside the bunker, as it had done on previous occasions, but as the number of victims increased, it moved the executions to its shooting range in Hebertshausen, about a mile and a half away. Here, Camp SS men forced the Soviet soldiers to strip naked and line up. Everything happened at great speed. A commando of SS men pounced on those in the first row, with five SS men grabbing one prisoner each, dragged them around a corner, and shackled them to posts. Then an SS squad opened fire, often shooting wildly at the helpless victims.
