Hi Mr.Miller, Thank you for this information. The reason I asked where Co.A was during that period is because my ggrandfather,Pvt. Vernon H. Lockley was with the unit and his last roll call was on march 20,1863 in which Capt.Rowland listed him as "detailed to herd beeves." That is the last mention of him,and according to family records,he simply vanished forever. I would like to know what happened since he never came home again. Regards,Charles Lockley.
