At the end of a year La Barre was replaced by the marquis de Denonville, a man of ability and courage, who, though he showed some vigour in marching against the western Iroquois tribes, angered rather than intimidated them, and the massacre of Lachine (5th of August 1689) must be regarded as one of the unhappy results of his administration.
On the 6th of July he left Lachine at the head of a considerable force for the village of the Onondagas, where he arrived a month later.
