It would be unusual for Federal soldiers to be transported as far back as the John Cunningham farm. I regard it as an act of kindness or respect on the part of the Confederates to devote an ambulance for this purpose. However, after the Confederates retreated, those same Federal soldiers in more remote locations would tend to be overlooked by their own citizens. Greg Coco, in A Vast Sea of Misery, cites an August 7, 1863 article in a Michigan newspaper that illustrates the point:
(Two nurses, Mrs. Brain and Mrs. Barnard) accidentally learned the revolting fact, that two or three Union soldiers were lying in a barn, about three miles from town. The barn belongs to a Mr. Cunningham, a true Union man, and is used as a rebel hospital. They immediately set out, after ascertaining the facts in the case, determined to remedy the thing, by having them brought to town. They visited the barn ... and found them; but in a sad and neglected condition, having laid on a bundle of straw for four weeks with broken thigh bones, and that, too, without being set or cared for properly. The rebel surgeon in charge of the hospital seemed to be a humane man, and rendered an excuse for their condition, that he had nothing to do with it; but this was really no excuse., for everything that was needed could have been had by simply asking for it. ... One of them belonged to the 4th Michigan. ...
I have no further information on the two nurses. Corporal Beden Beabout (alternative spelling) of Company D had his leg amputated, but died on August 9, according to, Union Casualties at Gettysburg, by Travis W. and John W. Busey, 2:941. A Corporal James A. Beabout (a brother?) of the same company was listed as killed.
At Gettysburg, the companies of the 140th were arranged in this order (from left to right): A – E – H – B – K – D – G – F – C. Company K was the color company. Early on in their fight on July 2, the three right companies of the regiment were pushed out into the open field west of the woods that are on the west side of the Wheatfield and, thus exposed, suffered the highest casualties. Company D would have been just at the edge of the woods, squaring off primarily against men of the 3rd South Carolina of Kershaw's brigade, who were assisted by the 2nd South Carolina and a few men of the 50th Georgia of Semmes' brigade. I would guess that Beden and James Beabout were most likely struck down between 6:25 to 6:55 p.m. on July 2, when Wofford's advance compelled the remaining members of the regiment to hastily withdraw. My attached draft map shows the estimated situation at 6:45 p.m.
