Fort Detroit Church and the center of what became the Petite Côte settlement of French colonists by the mid-18th century. Later encompassed by Sandwich (now Windsor), Petite Côte was the oldest continually occupied European settlement in what later became Ontario. The first major conflict of Fort Detroit occurred in March 1706 while Cadillac was away. The Ottawa heard a rumor about a Huron tribe ambush. The Ottawa attacked and killed several members of the Miami tribe. The Miami sought safety in the fort, where they were defended by the soldiers. The French killed about 30 Ottawa warriors when they attacked the fort.
