ure a messenger came from Hovey, asking for more
reinforcements. There were none to spare. I then gave an order to move
McPherson's command by the left flank around to Hovey. This uncovered
the rebel line of retreat, which was soon taken advantage of by the
enemy.

During all this time, Hovey, reinforced as he was by a brigade from
Logan and another from Crocker, and by Crocker gallantly coming up with
two other brigades on his right, had made several assaults, the last one
about the time the road was opened to the rear. The enemy fled
precipitately. This was between three and four o'clock. I rode
forward, or rather back, to where the middle road intersects the north
road, and found the skirmishers of Carr's division just coming in.
Osterhaus was farther south and soon after came up with skirmishers
advanced in like manner. Hovey's division, and McPherson's two
divisions with him, had marched and fought from early dawn, and were not
in the best condition to follow the retreating foe. I sent orders to
Osterhaus to pursue the enemy, and to Carr, whom I saw personally, I
explained the situation and directed him to pursue vigorously as far as
the Big Black, and to cross it if he could; Osterhaus to follow him.
The pursuit was continued until after dark.

The battle of Champion's Hill lasted about four hours, hard fighting,
preceded by two or three hours of skirmishing, some of which almost rose
to the dignity of battle. Every man of Hovey's division and of
McPherson's two divisions was engaged during the battle. No other part
of my command was engaged at all, except that as described before.
Osterhaus's and A. J. Smith's divisions had encountered the rebel
advanced pickets as early as half-past seven. Their positions were
admirable for advancing upon the enemy's line. McClernand, with two
divisions, was within a few miles of the battle-field long before noon
and in easy hearing. I sent him repeated orders by staff officers fully
competent to explain to him the situation. These traversed the wood
separating us, without escort, and directed him to push forward; but he
did not come. It is true, in front of McClernand there was a small
force of the enemy and posted in a good position behind a ravine
obstructing his advance; but if he had moved to the right by the road my
staff officers had followed the enemy must either have fallen back or
been cut off. Instead of this he sent orders to Hovey, who belonged to
