On June 15, 1832, President Andrew Jackson, displeased with Atkinson's handling of the war, appointed General Winfield Scott to take command. Scott gathered about 950 troops from eastern army posts just as a cholera pandemic had spread to eastern North America. As Scott's troops traveled by steamboat from Buffalo, New York, across the Great Lakes towards Chicago, his men started getting sick from cholera, with many of them dying. At each place the vessels landed, the sick were deposited and soldiers deserted. By the time the last steamboat landed in Chicago, Scott had only about 350 effective soldiers left. On July 29, Scott began a hurried journey west, ahead of his troops, eager to take command of what was certain to be the war's final campaign, but he would be too late to see any combat.
