and felt jubilant.  At that moment, also, my brigade passed Hunter’s division; but Heintzelman’s was still ahead of us, and we followed its lead along the road toward Manassas Junction, crossing a small stream and ascending a long hill, at the summit of which the battle was going on.  Here my regiments came into action well, but successively, and were driven back, each in its turn.  For two hours we continued to dash at the woods on our left front, which were full of rebels; but I was convinced their organization was broken, and that they had simply halted there and taken advantage of these woods as a cover, to reach which we had to pass over the intervening fields about the Henry House, which were clear, open, and gave them a decided advantage.  After I had put in each of my regiments, and had them driven back to the cover of the road, I had no idea that we were beaten, but reformed the regiments in line in their proper order, and only wanted a little rest, when I found that my brigade was almost alone, except Syke’s regulars, who had formed square against cavalry and were coming back.  I then realized that the whole army was “in retreat,” and that my own men were individually making back for the stone bridge.  Corcoran and I formed the brigade into an irregular square, but it fell to pieces; and, along with a crowd, disorganized but not much scared, the brigade got back to Centreville to our former camps.  Corcoran was captured, and held a prisoner for some time; but I got safe to Centreville.  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.  I aroused my aides, gave them orders to call up the sleeping men, have each regiment to leave the field by a flank and to take the same road back by which we had come.  It was near midnight, and the road was full of troops, wagons, and batteries.  We tried to keep our regiments separate, but all became inextricably mixed.  Toward morning we reached Vienna, where I slept some hours, and the next day, about noon, we reached Fort Corcoran.

A slow, mizzling rain had set in, and probably a more gloomy day never presented itself.  All organization seemed to be at an end; but I and my staff labored hard to collect our men into their proper companies and into their former camps, and, on the 23d of July, I moved the Second Wisconsin and Seventy-ninth New York closer in to Fort Corcoran, and got things in better order than I had expected.  Of course, we took it for granted that the rebels would be on our heels, and we accordingly prepared to defend our posts.  By the 25th I had collected all the materials,
