Thanks for all of the info in your reply Hugh. I can definitely tell that we have both searched through much of the same info and maps. Please see my reply below to Robert Crook for more info from the Waring diary. I believe Waring’s account is correct and that Howard was mistaken. I have found a few other errors in his sketch. I sure am glad he wrote it though, because it has been invaluable to me with my research and is an excellent source of info for anyone interested in Cobb's Legion Cavalry. Howard didn’t actually identify the location or the date of the battle that my ancestor was killed in, but I have a copy of a page out of an old family bible where my ancestor’s sister wrote “Lt. T. J. Dunnahoo was killed the 12th day of April 1865 at the last battle of North Carolina.” For awhile I thought that perhaps he had been wounded at Bentonville and didn’t die until 12 April, but after reading the Waring diary and also after finding Lt. Dunnahoo’s grave (Oakwood also had him listed as being killed on 12 April), I’m 100% sure that he was killed during the action at Swift Creek.
Mark L. Bradley, author of Last Stand in the Carolinas: The Battle of Bentonville and This Astounding Close: The Road to Bennett Place, once told me that he believes the action at Swift Creek took place just to the west of the North Carolina State Railroad, but I have had other gentlemen, who also live in that part of NC, tell me that it took place east of the railroad.
