Henry Halleck Papers
Major General Henry W. Halleck commanded the Department of Missouri and Department of the Mississippi from November 1861 through July 1862. He was then appointed General-in-Chief, and served as a military advisor to Abraham Lincoln. Contained within the Halleck papers is a single order placed on March 12, 1862 just months prior to being ordered to Washington. Halleck requested Major William Prince at Fort Leavenworth to advance regiments from there to Kansas City and Independence, Missouri. His orders were to clear the border counties of “marauding bands of rebels.”
