On August 14, Major-General Isaac Brock, British commander of Upper Canada, arrived at Fort Malden and began preparations for attacking Hull at Fort Detroit. Tecumseh, upon hearing of Brock's plans, reportedly turned to his companions and said, "This is a man!" Tecumseh and Brock "formed an immediate friendship that served to cement the alliance." Brock's high esteem for Tecumseh likely contributed to a popular belief that Tecumseh was appointed a brigadier general in the British Army, though this is a myth.
