General Joseph E. Johnston, Narrative of Military Operations During the Civil War

The Confederate loss on the 19th, according to the morning reports of the 20th, was one hundred and eighty killed, twelve hundred and twenty wounded, and five hundred and fifteen missing: in all, nineteen hundred and fifteen. On the 20th, it was six killed, ninety wounded, and thirty-one missing; and on the 21st, thirty-seven killed, one hundred and fifty-seven wounded, and one hundred and seven missing: amounting, in the three days, to two hundred and twenty-three killed, fourteen hundred and sixty-seven wounded, and six hundred and fifty-three missing. Most of the latter were captured in rear of the Federal lines, which they passed through in small parties by the intervals caused by the thicket in which the fight ended on the 19th. Several such parties, included in the number of missing reported above, escaped around the flanks of the Federal army, and rejoined their regiments near Smithfield. Our losses were supplied by the arrival, on the 20th and 21st, of about two thousand men of the Army of Tennessee in several detachments. Major-General Cheatham came with one of them.

We captured nine hundred and three prisoners in the three days, but had no means of ascertaining the number of the enemy's killed and wounded; but, as our troops were generally successful, and were covered by intrenchments in a part of the fighting on the 19th, all of that of the 20th, and most of that on the 21st, it must have exceeded ours very much. From the appearance of the field, and the language of Federals, it largely exceeded four thousand.
