Rufus Ingalls to Sawtelle, June 13, 1863

Colonel SAWTELLE, Quartermaster in Charge, Aquia: All the troops will move to-night and to-morrow. I think the railroad will be safe all day to-morrow, but Mr. Wright should draw in his rolling-stock as fast as possible inside of Potomac Creek, and get it away as fast as he can. RUFUS INGALLS, Brigadier-General, Chief Quartermaster. HEADQUARTERS ARMY OF THE Potomac, June 13, 1863—10 p. m. General Haupt : Colonel Sawtelle is at Aquia Creek, to conduct, with Mr. Wright, the withdrawal. He will then take post at Alexandria. My best quartermasters will be at different stations on the Orange and Alexandria Railroad, as soon as they can take part, with plenty of employés. Iam determined there shall be noconfusion, nor shall the cars be used as storehouses, or detained, if in my power to prevent it. Rely on that. IT hope Mr. Wright communicated with you as to the withdrawal. Weshall accomplish it during to-night, to-morrow, and the following night. General Warren is charged with defending the withdrawal, in concert with Captain Magaw, of the Navy.

RUFUS INGALLS,
