M Jeff Thomson in his report to Sterling Price infers H L Routt's company consisted of 80 men. Reportedly there was a group of men from Buchanan county that joined Routt for the Liberty Arsenal Raid.
As you know Routt was a staunch Democrat, anti=abolitionist lawyer from Liberty who is in the news as early as 1845 proposing physical action against Freesoilers and Abolitionists. He was much offended by the 1855 raid on the Arsenal and likely saw his actions as protecting state property from being seized again by abolitionists in 1861.
The Canton Press in Dec 1866 names one "Adamson" as a member of Routt's army at Liberty.
History of Clay and Platte Counties lists Routt as Captain of the Liberty Mounted Rangers with LS Talbott, George W Morris and JW Gillepsie as Lieutenants. Yet in another section of the same book, Gilepsie is mentioned as orderly sgt and JC Dunn as Lt. On Page 196 the description of the seizure relates a company from Jackson County commanded by Capt McMurray from Independence was on hand the whole commanded by Col Routt. Dunn was a circuit court judge in Liberty at the time.
