The British, with the support of the Indian Confederation, had constructed Fort Miamis in spring 1794 to hold the Maumee Valley and stop Wayne's advances towards Detroit. It also afforded the British additional means to solidify Indian support against the U.S. settlers moving into the Ohio Territory. The fort consisted of four bastions surrounded by a 25-foot-deep trench lined with rows of stakes. The British also placed 14 cannon in the fort to thwart any attackers.
Despite the promise from the British that the fort would offer protection to the Indians, warriors retreating to the fort were not allowed to enter and instead had to proceed to the mouth of Swan Creek. After the battle General Wayne felt that Fort Miamis was too strong to be forced, and he returned to Roche de Bout.
