invading force almost daily, Price's first full battle did not come until September 27, at Pilot Knob, southwest of St. Louis in Iron County. Price's Missouri Expedition included the following battles: Fort Davidson (September 27, 1864) Having learned of Price's entry into Missouri, Union Brigadier General Thomas Ewing, Jr. moved down the railroad with reinforcements from St. Louis to Ironton to retard Price's advance. Price attacked Ewing's force on the morning of September 27, driving the Federals back into Fort Davidson, a redoubt of earthworks and wooden palisades near a hill called Pilot Knob. After maneuvering elements of his army onto the hills surrounding the fort, Price launched repeated assaults in the late afternoon hours, suffering horrific casualties. During the night, the Federals quietly evacuated the fort and then blew up its powder magazine with a timed fuse. Price had taken the fort, but he had paid a high price in lives and ammunition, giving the Union forces the time necessary to concentrate and oppose his expedition, while gaining little of any lasting military value. That same day, 130 miles to the northwest, a band of pro-Confederate guerrillas led by William "Bloody Bill" Anderson sacked the town of Centralia, executing 24 unarmed Union soldiers in the infamous Centralia Massacre. Anderson, an associate of the notorious bushwhacker Col. William C. Quantrill, was accompanied by Frank and Jesse James. In response to these events XVI Corps now moved to St. Louis, reinforced by Pleasonton. Seeing that his primary target of St. Louis was too strongly defended to take, Price turned west toward Jefferson City. He eventually discovered, however, that the capital was also too heavily fortified, and he bypassed it and continued west toward Kansas City, Missouri. Glasgow (October 15) Price sent a detachment under Generals Shelby and John Bullock Clark, Jr. to Glasgow to capture weapons and military supplies said to be in an arms warehouse there. The Confederate artillery opened fire before dawn on October 15, and Shelby's horse soldiers advanced on Glasgow, forcing the defenders back toward their fortifications on Hereford Hill, where they formed a defensive line. Convinced he could not withstand another attack, Union Colonel Chester Harding surrendered about 1:30 p.m. Harding had been able to destroy some military stores, but Price's men located muskets, overcoats, and army horses. The Confederates rested in town for three days before rejoining the main column marching on Kansas City. This
