In August 1813, American Major George Croghan was in charge of 160 soldiers at Fort Stephenson, a base on the Sandusky River in what is now Sandusky County, Ohio which guarded a nearby supply depot. British commander Henry Procter arrived with a superior force that included at least 500 British regulars, 800 American Indians under Major Robert Dickson, and at least 2,000 more under Tecumseh. Procter met Croghan under a flag of truce and urged him to surrender, but Croghan refused. The British then bombarded the fort by artillery and gunboat, to little effect. Croghan returned fire with his single cannon, "Old Betsy" while frequently changing its position in the hopes that the British would believe he had more than one artillery piece. When Croghan's supply of ammunition ran low, he ordered his men to cease fire.
