I was checking out the order of battle for the sixth offensive battle of Darbytown Road. My ancestors served in the 142nd NYIV. Their unit was in the X corps, 2nd Division, 1st Brigade under Col. N. M. Curtis. Their unit is mistakenly labeled as the 142nd Pennsylvania on the list.
My 3rd great grandfather, First Sgt. David Hutchinson of Co. K, was killed in the assault on the defenses at Darbytown Road on October 27th or 28th.
His cousin, Johnston Hutchinson, who served in the same company, suffered a gunshot wound to the right thigh in the assault on the Petersburg defenses, battle of Harrison’s Creek, on June 18th, 1864. He was taken to General Hospital Chesapeake at Fortress Monroe, and lingered there until he died on the 18th of August, 1864. He’s buried in Hampton National Cemetery, Hampton, VA.
Any new information regarding the 6th offensive?
Brent,
Check out the new book Richmond Must Fall: The Richmond-Petersburg Campaign, October 1864. It covers this battle in detail.
