I saw everything favorable for us along the line of our left and centre.
When I came to the right appearances were different. The enemy had come
out in full force to cut his way out and make his escape. McClernand's
division had to bear the brunt of the attack from this combined force.
His men had stood up gallantly until the ammunition in their
cartridge-boxes gave out. There was abundance of ammunition near by
lying on the ground in boxes, but at that stage of the war it was not
all of our commanders of regiments, brigades, or even divisions, who had
been educated up to the point of seeing that their men were constantly
supplied with ammunition during an engagement. When the men found
themselves without ammunition they could not stand up against troops who
seemed to have plenty of it. The division broke and a portion fled, but
most of the men, as they were not pursued, only fell back out of range
of the fire of the enemy. It must have been about this time that Thayer
pushed his brigade in between the enemy and those of our troops that
were without ammunition. At all events the enemy fell back within his
intrenchments and was there when I got on the field.

I saw the men standing in knots talking in the most excited manner. No
officer seemed to be giving any directions. The soldiers had their
muskets, but no ammunition, while there were tons of it close at hand.
I heard some of the men say that the enemy had come out with knapsacks,
and haversacks filled with rations. They seemed to think this indicated
a determination on his part to stay out and fight just as long as the
provisions held out. I turned to Colonel J. D. Webster, of my staff,
who was with me, and said: "Some of our men are pretty badly
demoralized, but the enemy must be more so, for he has attempted to
force his way out, but has fallen back: the one who attacks first now
will be victorious and the enemy will have to be in a hurry if he gets
ahead of me." I determined to make the assault at once on our left. It
