    27. Drake, Janet M. Remember me to all the friends: Civil War Letters from George W. Harwood Massachusetts 36th RegimentDamianos Publishing, p. 219: George Harwood writes in an undated fragment: “We expect that the 34th Mass will pass through here today they belong to the 24 corps + have been down to Lynchburg Capt Leach is in command of the Regt…” Editor Jan Drake places this as possibly June 17-18, 1864, but this is incorrect because the 24th Corps didn’t exist until December 1864, the 34th Massachusetts was not in the vicinity of Petersburg until just before Christmas 1864, and Leach was not in command of the 34th Massachusetts until March 1865 per returns in the Official Records. I believe this fragment should be dated at some point in late March 1865, probably on March 28-29, 1865 as a good portion of the 24th Corps was passing behind the Union armies around Petersburg to add punch to a left flank attack near Hatcher’s Run.  Harwood would have gotten wind of their near approach to him and set out to meet Leach.  See my original article on Grant’s planning for the Ninth Offensive from March 24-28, 1865 for more details on the movements of Ord’s 24th Corps. I cannot, however, prove this. More research is needed.
