Luther pitched in very firmly on the side of the princes; he made a tour of southern Saxony – Stolberg, Nordhausen, and the Mansfeld district – in an attempt to dissuade the rebels from action, although in some of these places he was roundly heckled. He followed this up with his pamphlet "Against the Robbing and Murdering Hordes of Peasants", calling for the ruthless suppression of the revolt. This had a title and a timing that could not have been more ill-considered since it was the German peasantry who at that time died in their thousands at the hands of the princely armies. Estimates put the figure at 70,000–75,000, possibly even as high as 100,000.
