Career
As lieutenant to Peter the Hermit he co-led the People"s Crusade at the beginning of the First Crusade. While they passed through Germany and Hungary uneventfully, Walter"s followers plundered the Belgrade area, drawing reprisals upon themselves. From here they continued to Constantinople under Byzantine escort.
Walter and Peter joined forces at Constantinople where Alexius I Comnenus provided transport across the Bosporus.
Despite Peter"s entreaties to restrain themselves, the Crusaders engaged the Turks at once and were cut to pieces. Peter had returned to Constantinople, either for reinforcements or to protect himself.
