even now more than ten thousand strong, was in four divisions, commanded
by Generals Twiggs, Worth, Pillow and Quitman. There was also a cavalry
corps under General Harney, composed of detachments of the 1st, 2d, and
3d dragoons. The advance commenced on the 7th of August with Twiggs's
division in front. The remaining three divisions followed, with an
interval of a day between. The marches were short, to make
concentration easier in case of attack.

I had now been in battle with the two leading commanders conducting
armies in a foreign land. The contrast between the two was very marked.
General Taylor never wore uniform, but dressed himself entirely for
comfort. He moved about the field in which he was operating to see
through his own eyes the situation. Often he would be without staff
officers, and when he was accompanied by them there was no prescribed

side-ways--with both feet on one side--particularly on the battlefield.
General Scott was the reverse in all these particulars. He always wore
all the uniform prescribed or allowed by law when he inspected his
lines; word would be sent to all division and brigade commanders in
advance, notifying them of the hour when the commanding general might be
expected. This was done so that all the army might be under arms to

uniform, cocked hat, aiguillettes, sabre and spurs. His staff proper,
besides all officers constructively on his staff--engineers, inspectors,
quartermasters, etc., that could be spared--followed, also in uniform
and in prescribed order. Orders were prepared with great care and
evidently with the view that they should be a history of what followed.

In their modes of expressing thought, these two generals contrasted
quite as strongly as in their other characteristics. General Scott was
