William F. Fox, Lt. Col. U. S. V., Regimental Losses in the American Civil War, 1861-1865: A Treatise on the extent and nature of the mortuary losses in the Union regiments, with full and exhaustive statistics compiled from the official records on file in the state military bureaus and at Washington

The next greatest loss in the heavy artillery is found in the Eighth New York, of Gibbon's Division, Second Corps, in which regiment 19 officers and 342 enlisted men were killed or died of wounds during their three years term of service. Like the First Maine, it did not go to the front nor see any fighting until the last year of its service, all its losses occurring during the last ten months of the war.

The following list embraces all the heavy artillery regiments in which the number of killed, or died of wounds, exceeded two hundred:

The Second Pennsylvania Heavy Artillery carried, from first to last, over 5000 names on its rolls. In fact, it comprised two regiments-one in the Ninth, and one in the Eighteenth Corps. In the spring of 1864, the regiment, 1800 strong, joined the Second Division of the Eighteenth Corps, at Cold Harbor.

A cavalry regiment numbered 1200 men, nominally, and was divided into twelve companies of one hundred each. They did not suffer such severe losses in particular engagements as did the infantry, but their losses were divided among a great many more battles. The cavalry went into action very much oftener than infantry. Although mounted and armed with sabres, much of their fighting was done dismounted, and with carbines. The mounted regiments which lost the most men, killed or fatally wounded in action, were the following:

The light artillery was composed of batteries with a maximum strength of 150 men and six guns. Before the war closed many of them were reorganized as four-gun batteries. In
