General Harrison left Snelling in charge of Fort Harrison (11 November 1811 to May 1812) as a reward for his actions at Tippecanoe.
He was recognized for his performance at the Battle of Tippecanoe, and was assigned to command Fort Harrison during the winter of 1811–12. on the Wabash River at the present site of Terre Haute, Indiana. During the War of 1812, he received the rank of Captain and was sent to Fort Detroit, where he met and married Abigail Hunt.
Snelling's activities before Hull surrendered Detroit.
