Before night all the troops, and by the evening of the 5th the trains of more than four thousand wagons, were safely on the south side of the river.
There never was a corps better organized than was the quartermaster's corps with the Army of the Potomac in 1864.

With a wagon-train that would have extended from the Rapidan to Richmond, stretched along in single file and separated as the teams necessarily would be when moving, we could still carry only three days' forage and about ten to twelve days' rations, besides a supply of ammunition.

To overcome all difficulties, the chief quartermaster, General Rufus Ingalls, had marked on each wagon the corps badge with the division color and the number of the brigade.

At a glance, the particular brigade to which any wagon belonged could be told.

The wagons were also marked to note the contents: if ammunition, whether for artillery or infantry; if forage, whether grain or hay; if rations, whether, bread, pork, beans, rice, sugar, coffee or whatever it might be.
