This was August 6, the day of General Pierce’s arrival. The army had been re-apportioned into four divisions instead of three.

The First Division was about the same as before: Second Artillery, Third Artillery, Fourth Infantry, in the First Brigade; Fifth Infantry, Sixth Infantry, Eighth Infantry, in the Second Brigade.

The Second Division (General Twiggs’) was about the same also: First Artillery, Third Infantry, and the Rifles, in the First Brigade; Fourth Artillery, Second Infantry, Seventh Infantry, with the Engineer company and Ordnance company, in the Second Brigade.

Major-General Pillow, who ranked next to General Scott, now, as full major-general, commanded the Third Regular Division. This contained the new regiments. The First Brigade, General Cadwalader, had the Voltigeurs or light riflemen, the Eleventh Infantry, the Fourteenth Infantry, and Captain John Magruder’s Light Battery I of the First Artillery. The Second Brigade, under the handsome General Franklin Pierce, had the Ninth, Twelfth and Fifteenth Infantry.

General Quitman commanded the Fourth Division. This was the Volunteers and the Marines. General Shields, who had recovered from his terrible wound received at Cerro Gordo, had, of course, been given the Volunteer brigade, composed of the Palmettos under Colonel P. M. Butler, and the Second New Yorkers under Colonel Ward B. Burnett. Lieutenant-Colonel E. S. Watson, of the Marines, had the Second Brigade—the Marines under Major Levi Twiggs and the Second Pennsylvania (a fine regiment equal to the Regulars) under Colonel W. B. Roberts, with Light Battery H of the Third Artillery under Lieutenant E. J. Steptoe, and Company C, Third Dragoons.

Then there was the cavalry brigade, commanded by the fire-eater, Colonel Harney, and containing Company F of the First Dragoons, under Captain Phil Kearny, nephew of General Stephen W. Kearny who had marched the First to California; six companies of the Second Dragoons, under Major E. V. Sumner, who also had recovered from his Cerro Gordo wound; and three companies of the new Third Dragoons, under Lieutenant-Colonel Thomas P. Moore.

The Twiggs Second Division was to lead the way, with Harney’s dragoons clearing the advance.

Everybody turned out early the next morning, Tuesday, August 7, to see the Second start for the Halls of Montezuma. The dragoons were already a short distance upon the road. A great throng of soldiers, sick and well, and of the townspeople, pressed around the plaza where General Twiggs drew up his regiments on parade before the government palace to be inspected by General Scott.

Inspection over with, he faced the long lines and raised his hat—and what a burly fighter he looked to be, with his short neck and his sunburned red face and his mane of white hair.
