The 5th South Carolina Infantry was part of Jenkin's Bde, Pickett's Div., First (Longstreet's) Corps from October 1862 to March-April 1863 : in mid-February 1863, both Pickett's and Hood's divisions (under the command of Longstreet) were first detached to Richmond, then sent to Suffolk in order to repel the Union threat in Southern Virginia and North Carolina.
Jenkins' Brigade switched temporarily from Pickett's Div. to French's Div. during Longstreet's campaign against Suffolk (sometimes known as "Tidewater operations"). French's Div. was composed of Davis' Mississippi Bde and Jenkins' Bde and was later identified as "Dept. Southern Virginia", when Longstreet's command was split in April 1, 1863. If your ancester died in late March, then he may have participated in early fight and siege operations against Union forces near Suffolk.
