Before other British outposts had learned about Pontiac's siege at Detroit, Native Americans captured five small forts in a series of attacks between May 16 and June 2. The first to be taken was Fort Sandusky, a small blockhouse on the shore of Lake Erie. It had been built in 1761 by order of General Amherst, despite the objections of local Wyandots, who in 1762 warned the commander that they would soon burn it down. On May 16, 1763, a group of Wyandots gained entry under the pretense of holding a council, the same stratagem that had failed in Detroit nine days earlier. They seized the commander and killed the other 15 soldiers, as well as British traders at the fort. These were among the first of about 100 traders who were killed in the early stages of the war. The dead were ritually scalped and the fort—as the Wyandots had warned a year earlier—was burned to the ground.
