Habitually each corps followed some main road, and the foragers, being kept out on the exposed flank, served all the military uses of flankers. The main columns gathered, by the roads traveled, much forage and food, chiefly meat, corn, and sweet-potatoes, and it was the duty of each division and brigade quartermaster to fill his wagons as fast as the contents were issued to the troops. The wagon-trains had the right to the road always, but each wagon was required to keep closed up, so as to leave no gaps in the column. If for any purpose any wagon or group of wagons dropped out of place, they had to wait for the rear. And this was always dreaded, for each brigade commander wanted his train up at camp as soon after reaching it with his men as possible.
I have seen much skill and industry displayed by these quarter-masters on the march, in trying to load their wagons with corn and fodder by the way without losing their place in column. They would, while marching, shift the loads of wagons, so as to have six or ten of them empty. Then, riding well ahead, they would secure possession of certain stacks of fodder near the road, or cribs of corn, leave some men in charge, then open fences and a road back for a couple of miles, return to their trains, divert the empty wagons out of column, and conduct them rapidly to their forage, load up and regain their place in column without losing distance. On one occasion I remember to have seen ten or a dozen wagons thus loaded with corn from two or three full cribs, almost without halting. These cribs were built of logs, and roofed. The train-guard, by a lever, had raised the whole side of the crib a foot or two; the wagons drove close alongside, and the men in the cribs, lying on their backs, kicked out a wagon-load of corn in the time I have taken to describe it.
