a comparatively insignificant rivulet might greatly delay the march of an army, if means for quickly crossing should not be provided. The general depth of a ford which a large force, with its appurtenances, can safely cross, is about three feet, and even then the bottom should be good and the current gentle. With a greater depth of water, the men are likely to wet their cartridge boxes, or be swept off their feet. There is a small stream about three miles from Alexandria, crossing the Little River turnpike, which has never been bridged, and which was once so suddenly swollen by rain that all the artillery and wagons of a corps were obliged to wait about twelve hours for its subsidence. The mules of some wagons driven into it were swept away. Fords, unless of the best bottom, are rendered impassable after a small portion of the wagons and artillery of an army have crossed them--the gravel being cut through into the underlying clay, and the banks converted into sloughs by the dripping of water from the animals and wheels.
A very amusing scene was presented at the crossing of Hazel River (a branch of the Rappahannock) last fall, when the Army of the Potomac first marched to Culpepper. The stream was at least three feet deep, and at various places four--the current very rapid--the bottom filled with large stones, and the banks steep, except where a narrow road had been cut for the wagons. The men adopted various expedients for crossing. Some went in boldly all accoutred; some took off shoes and stockings, and carefully rolled up their trousers; others (and they were the wisest) divested themselves of all their lower clothing. The long column struggled as best it could through the water, and occasionally, amid vociferous shouts, those who had been careful to roll up their trousers would step into a hole up to the middle; others, who had taken still more precautions, would stumble over a stone and pitch headlong into the roaring waters, dropping their guns, and splashing vainly about with their heavy knapsacks,
