After the end of World War II Auerswald was charged by an US-military tribunal in Dachau. The trial document lists a case where a Russian prisoner, begging for his life, was pushed by Auerswald into a fence secured by high voltage. He died immediately. The documentation also mentioned that 300 healthy prisoners were brought from Mauthausen to the sub-camp St. Aegyd. More than 50% died within the next few weeks or became severely sick so that they were brought back to Mauthausen where they died. Auerswald was the head of the St. Aegyd sub-camp at that time.
