My g grandfather, Henry Peters, served in Co. C 2nd MO Volunteer Infantry (3 Mo.) and in Co. E 2nd USRC MO Volunteer Infantry (3 Year). The second unit was mustered out in Sept. 1862 after only one year of service. They were stationed near Corinth, MS till the middle of August 1862, when they were suddenly sent back to St. Louis and almost immediately mustered out. The three year branch of the 2nd Regiment MO Volunteers (his first unit) continued to serve near Corinth. Has anyone found a reason for his second unit being mustered out so early? Jerry
