Grimball's Landing was on the Stono River on James Island about due west of Secessionville. For a thumbnail sketch of the engagement there in 1863, see http://www.cr.nps.gov/hps/ABPP/BATTLES/sc006.htm
Secessionville was the site of an earlier battle in 1862, and much of the area has been preserved as part of a nature preserve. See http://www.dnr.sc.gov/managed/heritage/ftlamar/description.html
Hope this helps.
