Gallant Tennesseeans In Gettysburg Charge
Carried Their Flag to Crest of Cemetery Ridge, Where Grand Assault Was Made on Meade's Impregnable Position.
". . .to make matters clear as to who carried the battleflag of the Fourteenth Tennessee Regiment to the rock fence it will be necessary to go somewhat into details."
"Company G, commanded by Captain Harry Bullock, was the color guard, and Thomas Davidson, of that company, color-bearer."
[During the advance,] "When we had gone about one-third of the distance I heard the dull thud of a bullet as it struck Tom Davidson. As he staggered forward he handed me the colors, saying as he fell, 'Bob, take the flag; I am shot!' A few steps further on Columbus Horn, a color guard from Company G, ran up and said: 'Bob, give me the colors; they belong to Company G.' Fifty feet further on Horn was shot in the head and fell. Without stopping I picked up the flag, but had proceeded only a few paces when a color guard of Company C ran up and claimed it. This happened just as we reached the Emmitsburg road. I am not sure of his name but think it was Powell. He carried the flag across the road and fell dead, I believe, just beyond the slab fence. We were then within seventy yards of the rock fence, and Boney Smith, a color guard form Company F, picked up the flag and I saw him with it at the rock fence."
"Dreading capture, I determined to make the effort to get back to our artillery. Seeing Smith with the flag, I asked him if he would bring it out, and being assured he would, I commenced my flight across that open field. . ."
". . .I reached Pegram's Battery. . . In a few minutes Smith appeared but without the colors. Being asked what became of them, he said his attention was for some reason drawn away from the flag, and when he looked around for it, it was gone. . . . He had the reputation of being one of the bravest men in the Fourteenth Regiment."
"Recently I had a letter from an old comrade (W. P. Davis of Company K), and in speaking of the capture of the flag he says: 'The last man who had the flag at the rock fence (the Federal line) was Drew Marshall, of Company K, and he left it there." I only know that Boney Smith carried the flag to the rock fence, and it was in his possession when I left him there."
