The last-named officer did his utmost to drive the British out of Detroit. His troops were volunteers, brave but undisciplined, and displayed their most effective work in scattered fighting and against the Indians; but their success was not decisive. When the swamps and lakes of the Northwest were sufficiently frozen to bear their weight, Harrison repeated his attempts to expel the British from Detroit. His advance, under General Winchester, was attacked on the River Raisin by the British, led by General Proctor. Winchester was as prompt as General Hull in surrendering. Proctor allowed his Indians to massacre the wounded prisoners, most of whom were Kentuckians. Thereafter, when the Kentucky troops rushed into battle they raised the war-cry, "Remember the Raisin!" The disaster to Winchester caused Harrison to fall back to Fort Meigs, which stood near the site of the present town of Defiance. There, in the spring of 1813, he was besieged by Proctor. A force of Kentuckians relieved him, after severe loss, and Proctor retreated. Some months later he again advanced against Fort Meigs, but was repulsed, and marched to Fort Stephenson, where Fremont now stands. The besiegers consisted of 3,000 British and Indians, while the garrison numbered only 160, under the command of Major George Croghan, only twenty years of age. When Proctor ordered the youth to surrender he threatened that, in case of resistance, every prisoner would be tomahawked. Major Croghan replied that when the surrender took place there would not be a single man left to tomahawk. Although Croghan had but a single cannon, he made so gallant a defense that his assailants were repulsed, and Proctor, fearing the approach of Harrison, withdrew from the neighborhood. BATTLE OF THE THAMES. Perry's great victory on Lake Erie in September, 1813, as related further on, gave the Americans command of that body of water. Harrison's troops were placed on board of Perry's vessels and carried across from Ohio to Canada. They landed near Malden and Proctor fell back to Sandwich, with the Americans following. He continued his retreat to the Thames, where, with the help of Tecumseh, he selected a good battle-ground and awaited the Americans, who attacked him on the 5th of October. Proctor fled early in the battle, but his regulars fought bravely. The 1,500 Indians, under the lead of Tecumseh, displayed unusual heroism, but, when the great Tecumseh fell, they fled in a panic. The American victory was overwhelming and complete.
