Gerald, Poor choice of words .Engineer Tom said Explosives.I didn't see any use of them on the railroad in the time frame.I read part of Mr. Hoffman's unpublished, at the time, book. The actual book might have something.Col.W.P.Innes reached Tullahoma July 5th.I looked into the train as My GGGrandfather POW was taken away from Murfreesborough on the train to Chattanooga eventually to Atlanta.Bragg's retreat followed the tracks.Thanks for correcting!
