army at Cologne on 12 April 1096, planning to stop there and preach to the Germans and gather more crusaders. The French, however, were not willing to wait for Peter and the Germans and under the leadership of Walter Sans Avoir, a few thousand French crusaders left before Peter and reached Hungary on 8 May, passing through Hungary without incident and arriving at the river Sava at the border of the Byzantine territory at Belgrade. The Belgrade commander was taken by surprise, having no orders on what to do with them, and refused entry, forcing the crusaders to pillage the countryside for food. This resulted in skirmishes with the Belgrade garrison and, to make matters worse, sixteen of Walter's men had tried to rob a market in Zemun across the river in Hungary and were stripped of their armor and clothing, which was hung from the castle walls.

Peter obliged, and the next morning he set out. However, a few Germans got into a dispute with some
