In December 1859, shortly after John Brown's hanging for his raid in, Virginia, James Montgomery, of Kansas, unsuccessfully attempted to rescue two of Brown's jailed accomplices. Returning to Kansas, from Boston with money and arms, Montgomery recruited troops and publicly vowed to drive all proslavery residents from Kansas and made good on his pledge to take his war of liberation into Missouri. He and his Jayhawkers terrorized Lynn and Bourbon counties and dispersed the Federal Court at Fort Scott. He then began to terrorize Southwestern Missouri. In response, on November 25, 1860, Missouri's Governor Robert M. Stewart ordered General D. M. Frost to send a "Southwest Expedition" of some 600 state militiamen, largely from St. Louis, to the border counties to suppress Montgomery's jayhawking raids. The St. Louis Brigade consisted of: First Regiment of Infantry commanded by A.R. Easton; a Battalion of Engineers, National Guard, commanded by Major Pritchard; First Company of National Guard commanded by Capt. John B. Gray; Second Company National Guards commanded by Captain McKellops; Squadron of Cavalry commanded by Major Schaeffer; Missouri Light Cavalry commanded by Capt. Bendel; and, Missouri Light Infantry commanded by William Jackson. They took the train at the Pacific Railroad Depot to Franklin, MO then another train to Syracuse, then marched to Warsaw in Benton County. They were then scheduled to march to Osceola in St. Clair County. General Harney and another group also headed in that direction.
