Fort Leavenworth History

Fort Leavenworth, first known as Cantonment Leavenworth, was established by Henry Leavenworth on the Missouri River on May 8, 1827. Fort Leavenworth was the first settlement in Kansas territory and is the oldest active Army post west of the Mississippi River. Sitting on the bluffs overlooking the western bank of the Missouri River, the Fort initially served as a quartermaster depot, aresenal, and troop post, and was dedicated to protecting the fur trade and safeguarding commerce on the Santa Fe Trail. 

The post was evacuated in May, 1829 and occupied by Kickapoo Indians until it was re-garrisoned in the fall of 1829. The name of the post was changed to Fort Leavenworth on February 8, 1832.

Fort Leavenworth quickly became a primary destination for thousands of soldiers, surveyors, and settlers who were passing through on their way to the vast West. During these early years, soldiers from Fort Leavenworth protected wagon trains hauling supplies over the Santa Fe, Oregon and other trails to most forts, posts and military camps of the West, some as far as the Pacific Ocean.  In 1839, Colonel S. W. Kearney marched against the Cherokees with ten companies of dragoons, the largest U.S. mounted force ever assembled.

With the Kansas Nebraska Act of 1854, the Army spent much time attempting to keep the lid on the pot of trouble between the proslavery bushwhackers and the free soil jayhawkers.

Military expeditions from Fort Leavenworth under General Albert Sidney Johnston also assisted in 1857-58 with bringing the Mormons in Utah under Brigham Young back under federal control.

During the Civil War, thousand of recruits were recruited and mustered out from Camp Lincoln at Fort Leavenworth. Between 1861 and 1865, the regular army formed the foundation on which volunteer forces were built. Fort Leavenworth was considered a rich prize by Confederate General Sterling Price who advanced towards the fort in 1864. Before reaching the fort, however, he was defeated in the battle of Westport, Missouri on October 23, 1864.
