point.

On the 11th a strong division arrived from the Department of the
Missouri under General Herron, which was placed on our left. This cut
off the last possible chance of communication between Pemberton and
Johnston, as it enabled Lauman to close up on McClernand's left while
Herron intrenched from Lauman to the water's edge. At this point the
water recedes a few hundred yards from the high land. Through this
opening no doubt the Confederate commanders had been able to get
messengers under cover of night.

On the 14th General Parke arrived with two divisions of Burnside's
corps, and was immediately dispatched to Haines' Bluff. These latter
troops--Herron's and Parke's--were the reinforcements already spoken of
sent by Halleck in anticipation of their being needed. They arrived
none too soon.

I now had about seventy-one thousand men. More than half were disposed
across the peninsula, between the Yazoo at Haines' Bluff and the Big
Black, with the division of Osterhaus watching the crossings of the
latter river farther south and west from the crossing of the Jackson
road to Baldwin's ferry and below.

There were eight roads leading into Vicksburg, along which and their
immediate sides, our work was specially pushed and batteries advanced;
but no commanding point within range of the enemy was neglected.

On the 17th I received a letter from General Sherman and one on the 18th
from General McPherson, saying that their respective commands had
complained to them of a fulsome, congratulatory order published by
General McClernand to the 13th corps, which did great injustice to the
other troops engaged in the campaign. This order had been sent North
and published, and now papers containing it had reached our camps. The
order had not been heard of by me, and certainly not by troops outside
of McClernand's command until brought in this way. I at once wrote to
McClernand, directing him to send me a copy of this order. He did so,
and I at once relieved him from the command of the 13th army corps and
ordered him back to Springfield, Illinois. The publication of his order
in the press was in violation of War Department orders and also of mine.
