I saw General McDowell in Centreville, and understood that several of his divisions had not been engaged at all, that he would reorganize them at Centreville, and there await the enemy. I got my four regiments in parallel lines in a field, the same in which we had camped before the battle, and had lain down to sleep under a tree, when I heard some one asking for me. I called out where I was, when General Tyler in person gave me orders to march back to our camps at Fort Corcoran.
