FOX’S REGIMENTAL LOSSES

CHAPTER V. Pg. 51

The number of the drowned may seem large, but the average is less than three men to a regiment. This loss was occasioned largely by bathing and boating. At times, some regiment would sustain a larger loss while fording rivers, or landing from small boats in the surf. The Seventy-fifth Pennsylvania, while crossing the Shenandoah, in April, 1862, lost 2 officers and 51 men, drowned by the swamping of a scow.
