Porter Hanks, with his men, was shipped to the American lines at Fort Detroit. Hanks became a paroled prisoner of war, awaiting court martial for his surrender of Fort Mackinac. At Detroit, Lt. Hanks reported to the overall theater commander, Gen. William Hull. Hull was reported to have been much disturbed by Hanks' report that the British army was successfully implementing kinship alliances with Native warriors. Soon after Hanks's arrival, another British column attacked Fort Detroit. On the morning of August 16, while Hanks was awaiting a military tribunal, he and an officer standing beside him were killed by the random flight of a British artillery cannonball aimed at the American fort's personnel. The decapitation of Hanks completed the task of discouraging the American general, and later in the same day he surrendered the Detroit strongpoint.
