Note 18 — Chapter XXIII · CHANCELLORSVILLE

The troops carried eight days’ supplies: three days’ cooked rations with bread and groceries in the haversacks; five days’ bread and groceries in the knapsacks; five days’ “beef on the hoof.” The total weight carried by each man, including sixty rounds of ammunition, was 45 pounds. The reserve ammunition was carried principally by pack mules, and only a small number of waggons crossed the Rappahannock. Four pontoon bridges were laid by the engineers. One bridge took three-quarters of an hour to lay; the other three, one and a half hour to lay, and an hour to take up. Each bridge was from 100 to 140 yards long. O.R., vol. xxv, pp. 215, 216.
