Post of Corinth, Mississippi, 2nd Division, XVI Corps, to January 1864.

Of note, Companies C, D, F, I, and K were sent north to Chicago with prisoners of war after the capture of Arkansas Post on 11 January 1863.

[citation needed] During the solicitation for volunteers for the 2nd Division of XV Corps (Union Army)' diversionary[4] storming party, or "forlorn hope," that produced many Medals of Honor on 22 May 1863, the 113th's five companies were assigned a quota of three, unmarried men[5] (the quota for the division was two officers and fifty men from each of the three brigades[6]).

Even though the assault failed to breach the defenses, the regiment was kept forward and deployed as skirmishers[7] to constantly snipe at the defenders for the next two days, a role it would continue until the capitulation on 4 July 1863.
