division was deployed to the left of Carr and covered the enemy's entire
front. McPherson was in column on the road, the head close by, ready to
come in wherever he could be of assistance.

While the troops were standing as here described an officer from Banks'
staff came up and presented me with a letter from General Halleck, dated
the 11th of May. It had been sent by the way of New Orleans to Banks to
be forwarded to me. It ordered me to return to Grand Gulf and to
co-operate from there with Banks against Port Hudson, and then to return
with our combined forces to besiege Vicksburg. I told the officer that
the order came too late, and that Halleck would not give it now if he
knew our position. The bearer of the dispatch insisted that I ought to
obey the order, and was giving arguments to support his position when I
heard great cheering to the right of our line and, looking in that
direction, saw Lawler in his shirt sleeves leading a charge upon the
enemy. I immediately mounted my horse and rode in the direction of the
charge, and saw no more of the officer who delivered the dispatch; I
think not even to this day.

The assault was successful. But little resistance was made. The enemy
fled from the west bank of the river, burning the bridge behind him and
leaving the men and guns on the east side to fall into our hands. Many
tried to escape by swimming the river. Some succeeded and some were
drowned in the attempt. Eighteen guns were captured and 1,751 prisoners.
Our loss was 39 killed, 237 wounded and 3 missing. The enemy probably
lost but few men except those captured and drowned. But for the
successful and complete destruction of the bridge, I have but little
doubt that we should have followed the enemy so closely as to prevent
his occupying his defences around Vicksburg.
