Lewis Cass was born at Exeter, New Hampshire, October 9, 1783. Was appointed military governor of the territory of Michigan, October 14, 1813, and the following year made permanent governor, with William Woodbridge as secretary. The war of 1812-15 had but closed, the population had been scattered and was still exposed to the ravages of the hostile Indians. A brave, sagacious and firm had was therefore needed to restore order and confidence, as well as to rebuke outrages perpetrated by the English authorities in Canada under the plea that they had a right to invade the territory in search of and arrest deserters from their army.
