At length, on 11 May, Müntzer and what remained of his troops arrived outside the town of Frankenhausen, meeting up with rebels there who had been asking for help for some time. No sooner had they set up camp on a hill than the princes’ army arrived, having already crushed the rebellion in southern Thuringia. On 15 May, battle was joined. It lasted only a few minutes, and left the streams of the hill running with blood. Six thousand rebels were killed, but only a few soldiers. Many more rebels were executed in the following days. Müntzer fled, but was captured as he hid in a house in Frankenhausen. His identity was revealed by a sack of papers and letters which he was clutching. On 27 May, after torture and confession, he was executed alongside Pfeiffer, outside the walls of Mühlhausen, their heads being displayed prominently for years to come as a warning to others.
