42nd Infantry Regiment was organized at Oxford, Mississippi, in May, 1862, and in June moved to Virginia with about 750 officers and men. Its companies were recruited in the counties of Carroll, Coahoma, Tate, De Soto, Panola, Lafayette, Union, Pontotoc, Marshall, Benton, and Tippah. For a time it served on garrison duty in the Department of Richmond, then was assigned to General J.R. Davis' Brigade, Army of Northern Virginia. The 42nd was active from Gettysburg to Cold Harbor, endured the hardships of the Petersburg siege south of the James River, and saw action around Appomattox. It lost forty-six percent of the 575 engaged at Gettysburg, had 8 disabled en route from Pennsylvania, and had 6 killed and 25 wounded during the Bristoe Campaign. The regiment surrendered 1 Lieutenant, 1 Chaplain, and 5 enlisted men on April 9, 1865. The field officers were Colonels William A. Feeney, Hugh R. Miller, and Andrew M. Nelson; Lieutenant Colonel Hillery Mosely; and Major Robert W. Locke.

October 27. [1864]— [Engaged at] Hatcher's Run.
The regiment is now encamped near the Dabney House,
about six miles southwest of Petersburg. Picket and fatigue duty
during the winter has been very heavy. Some bad men here
deserted to the enemy, but the good ones have worked like Tro-
jans and again it is believed [they] will fight like Spartans.
I hereby certify that the foregoing record of names, dates,
facts and historical memoranda is correctly given.
A. M. NELSON,
Colonel.
Supplement to the Offical Records
......
In the latter part of February, 1865, Col. A. M. Nelson was in command of the brigade and General Davis of the division. Colonel Nelson was yet in command of the brigade when the Petersburg line was broken April 2, 1865, and he was captured, with most of his command. The colors of the Forty-second were captured by Corporal Charles W. Dolloff, Eleventh Vermont, of Getty's Division. The Vermont Brigade claimed the honor of being the first to break the line of gray. Captain Tilden was credited with the capture of 2 cannon, 11 officers and 62 men of the Forty-second.
