I have a similar question. My Great-great grandfather’s brother, Martin Van Buren Reed, in Co. E, 31st Louisiana Infantry was killed at Chickasaw Bayou on Dec 29, 1862, one of the 63 Confederates killed in that battle. Since the Confederates won that engagement, I assume he was buried by comrades, but I have not been able to find any evidence his grave is marked. Any suggestions on where he may have been buried?
