 It is commonly believed that Peter's followers purely consisted of a massive group of untrained and illiterate peasants who did not even have any idea where Jerusalem was, but there were also many knights among the peasants, including Walter Sans Avoir, who was lieutenant to Peter and led a separate army.Lacking military discipline, in what likely seemed to the participants a strange land (Eastern Europe), Peter's fledgling army quickly found itself in trouble despite the fact they were still in Christian territory.The army led by Walter fought with the Hungarians over food at Belgrade, but otherwise arrived in Constantinople unharmed.
