While it is not known how many soldiers died during the First Battle of the River Raisin on January 18, 1813, "Eaton's Compilation" lists 397 Americans killed and 27 wounded during the January 22 conflict. Also, figures for those who were killed during the subsequent River Raisin Massacre are unknown, but estimates are as high as 100 killed. Two weeks after the battle, Brigadier General James Winchester reported that 547 of his men were taken as prisoners and only 33 escaped the battlefield. Many of those who were held as prisoners were detained at Fort Malden by the British until the end of the war over two years later. Winchester was imprisoned for more than a year before being released and reassigned to military service.
