Other unofficial crusaders from Swabia, led by Hartmann of Dillingen, along with French, English, Lotharingian and Flemish volunteers, led by Drogo of Nesle and William the Carpenter, as well as many locals, joined Emicho in the destruction of the Jewish community of Mainz at the end of May.
Maja 1096 je Emicho Flonheimski, včasih napačno imenovan tudi Emicho Leiningenski, napadel Jude v Speyerju in Wormsu.
