Here are short histories for each of these units:

23rd Regiment, South Carolina Infantry (Hatch's Coast Rangers)

23rd Infantry Regiment [also called Coast Rangers] was assembled at Charleston, South Carolina, in November, 1861. Most of the men were from Horry, Georgetown, Charleston, and Colleton counties. After being stationed in South Carolina, the regiment moved to Virginia and during the war served in General Evans', Elliot's, and Wallace's Brigade. It participated in the conflicts at Second Manassas, South Mountain, and Sharpsburg, then was ordered to North Carolina and later to Mississippi. The unit skirmished at Jackson, was sent to Charleston, and in the spring of 1864 returned to Virginia. It continued the fight in the trenches of Petersburg and around Appomattox. During the Second Manassas operations, August 6-20, 1862, this regiment lost sixty-eight percent of the 225 engaged, and all its field officers were wounded. It reported 10 killed, 22 wounded, and 5 missing in the Maryland Campaign, totalled 297 men in October, 1863, and had 49 killed or wounded at the Petersburg mine explosion. The 23rd had many disabled at Sayler's Creek and surrendered 5 officers and 103 men. Its commanders were Colonels Henry L. Benbow and Lewis M. Hatch; Lieutenant Colonels Allen J. Green, John M. Kinloch, Edgar O. Murden, and John Roberts; and Majors Matthew V. Bancroft, Henry H. Lesesne, L.P. Miller, and John M. Whilden.

25th Regiment, South Carolina Infantry (Eutaw Regiment)

25th Infantry Regiment [also called Eutaw Regiment] was organized and mustered into Confederate service in July, 1862. It was formed with men of the 11th Battalion who were from Charleston and the middle region of the state. It served in the Charleston area assigned to the Department of South Carolina, Georgia, and Florida, and in September, 1863, it was placed in General Hagood's Brigade. During the spring of 1864 the unit moved to Virginia and fought at Drewry's Bluff and Cold Harbor. Later it was involved in the Petersburg siege south and north of the James River and the North Carolina Campaign. The regiment lost 4 killed and 14 wounded at Secessionville, and there were 16 killed, 124 wounded, and 3 missing on Morris Island from July 10 to September 6, 1863. At this time it contained 36 officers and 491 men. In front of Petersburg, May 6-9, 1864, it reported 47 casualties and in the fight at the Weldon Railroad there were 2 killed, 29 wounded, and 70 missing. All the men present at Fort Fisher were captured, and the few who later served in the regiment surrendered in April, 1865. The field officers were Colonel Charles H. Simonton, Lieutenant Colonel John G. Pressley, and Major John V. Glover.
