1 this was the appearance of General Butler's Headquarters when the writer made the sketch at the close of 1864. the General occupied the two log-houses seen in the front, and his staff some of the smaller ones near. The mansion is seen in the rear of Headquarters.

2 Professor Coppee, author of Grant and his Campaigns, was furnished, by an officer of the Lieutenant-General's staff, with the following tabular statement of casualties in the Army of the Potomac, from May 5 to November 1, 1864.

During the period above named, according to the same statement, the number of prisoners captured by the Army of the Potomac was 15,378; the number of colors captured, 67; the number of guns captured by the Army of the Potomac, 32; the number lost by it, 25.

The above statement does not include the losses of the Army of the James, which, if added, would make the aggregate loss of the forces operating against Lee and the post of Richmond, during six months, the appalling number of 100,000 men. General Hancock said, in a letter to General Burns, that from the crossing of the Rapid Anna to the crossing of the James, he had lost his entire corps (25,000 in number). Its ranks had been kept full by re-enforcements. It is estimated that of the whole number captured, wounded, and missing (mostly prisoners), 30,000 afterward rejoined the army, making the total loss of effective force 70,000. The estimated loss of the Confederates, during the same period, including over 15,000 prisoners, was 40,000.
