The above man is the only W. Ward I found in the 3rd Miss.
Here is a summary of the Unit history -- http://mississippiscv.org/MS_Units/3rd_MS_INF.htm
The last card in his file states he was AWOL.
For more readiung on this unit I suggest H. Grady Howell's "To Live and Die In Dixie" a history of the 3rd Miss. Infantry Regt.
