Despite disclaimers by Mr.Matthews, crack Combat Studies Institute researcher, about Sterling Price's distancing himself from Bill Anderson, known by Yankee historians as "Bloody Bill," a quick perusal of my book manuscript still suggests a certain coziness between the two, wouldn't most of you neutrals agree?:

“Sanborn finally overtook and attacked Price’s rearguard at Versailles, sixty miles west of the capital, and reported to Pleasonton that the Confederates were headed for Boonville, Missouri. On October 10, Price marched into that town, where a Confederate report said, “all the people turned out to greet us.” While at Boonville, Price met with the guerrilla chiefs, Bill Anderson and Quantrill. He ordered Anderson and his 100 men to tear up the tracks of the North Missouri Railroad and Quantrill to destroy the Hannibal and St. Joseph line. Anderson took this opportunity to present Price, who he much admired, with a brace of silver pistols. Quantrill, who had learned to dislike Price, received his orders but made no effort to carry them out, possibly because he lacked enough men, but perhaps because he simply disliked Price. Obviously, though, the Missouri guerrillas were expected to work hand in hand with the Confederate Army and usually did from start to finish.”
