October 17, 1861
The Thirteenth regiment was mustered into U.S. service at Camp Treadway, Janesville.
The evidence
“All things being intrusted to proper authorities, recruiting began, *and before many weeks the regimental roster was completed, and consisted of six companies from Rock County exclusively, the balance from Green and Walworth Counties. The regiment, rank and file, as also the officers, was made up from the farm houses and workshops, with a goodly number from Milton College and the High School at Janesville, and went into camp northeast of the latter city, on what is now the County Fair Grounds, but at that date called "Camp Treadway." It was mustered into service October 17, 1861, and left the State for Fort Leavenworth, Kan. From thence it marched to Fort Scott, "where it remained until March 22, and was transferred to Lawrence, arriving there March 31, 1861. After a month's sojourn, the regiment went to Fort Riley, where it was fitted out for an expedition into Mexico.”
