The appearance of the troops about Washington was good, but it was manifest they were far from being soldiers.  Their uniforms were as various as the States and cities from which they came; their arms were also of every pattern and calibre; and they were so loaded down with overcoats, haversacks, knapsacks, tents, and baggage, that it took from twenty-five to fifty wagons to move the camp of a regiment from one place to another, and some of the camps had bakeries and cooking establishments that would have done credit to Delmonico.

While I was on duty with General Scott, viz., from June 20th to about June 30th, the general frequently communicated to those about him his opinions and proposed plans.  He seemed vexed with the clamors of the press for immediate action, and the continued interference in details by the President, Secretary of War, and Congress.  He spoke of organizing a grand army of invasion, of which the regulars were to constitute the “iron column,” and seemed to intimate that he himself would take the field in person, though he was at the time very old, very heavy, and very unwieldy.  His age must have been about seventy-five years.

At that date, July 4, 1861, the rebels had two armies in front of Washington; the one at Manassas Junction, commanded by General Beauregard, with his advance guard at Fairfax Court House, and indeed almost in sight of Washington.  The other, commanded by General Joe Johnston, was at Winchester, with its advance at Martinsburg and Harper’s Ferry; but the advance had fallen back before Patterson, who then occupied Martinsburg and the line of the Baltimore & Ohio Railroad.

The temper of Congress and the people would not permit the slow and methodical preparation desired by General Scott; and the cry of “On to Richmond!” which was shared by the volunteers, most of whom had only engaged for ninety days, forced General Scott to hasten his preparations, and to order a general advance about the middle of July.  McDowell was to move from the defenses of Washington, and Patterson from Martinsburg.  In the organization of McDowell’s army into divisions and brigades, Colonel David Hunter was assigned to command the Second Division, and I was ordered to take command of his former brigade, which was composed of five regiments in position in and about Fort Corcoran, and on the ground opposite Georgetown.  I assumed command on the 30th of June, and proceeded at once to prepare it for the general advance.  My command constituted the Third Brigade of the First Division, which division was commanded by Brigadier-General Daniel Tyler, a graduate of West Point, but who had seen little or no actual service.  I applied to General McDowell for home staff-officers, and he gave me, as adjutant-general, Lieutenant Piper, of the Third Artillery, and, as aide-de-camp, Lieutenant McQuesten, a fine young cavalry-officer, fresh from West Point.
