e if the plan had been his own. (*13)

On the 26th of May I sent Blair's division up the Yazoo to drive out a
force of the enemy supposed to be between the Big Black and the Yazoo.
The country was rich and full of supplies of both food and forage.
Blair was instructed to take all of it. The cattle were to be driven in
for the use of our army, and the food and forage to be consumed by our
troops or destroyed by fire; all bridges were to be destroyed, and the
roads rendered as nearly impassable as possible. Blair went forty-five
miles and was gone almost a week. His work was effectually done. I
requested Porter at this time to send the marine brigade, a floating
nondescript force which had been assigned to his command and which
proved very useful, up to Haines' Bluff to hold it until reinforcements
could be sent.

On the 26th I also received a letter from Banks, asking me to reinforce
him with ten thousand men at Port Hudson. Of course I could not comply
with his request, nor did I think he needed them. He was in no danger
of an attack by the garrison in his front, and there was no army
organizing in his rear to raise the siege.

On the 3d of June a brigade from Hurlbut's command arrived, General
Kimball commanding. It was sent to Mechanicsburg, some miles north-east
of Haines' Bluff and about midway between the Big Black and the Yazoo.
A brigade of Blair's division and twelve hundred cavalry had already, on
Blair's return from the Yazoo, been sent to the same place with
instructions to watch the crossings of the Big Black River, to destroy
the roads in his (Blair's) front, and to gather or destroy all supplies.

On the 7th of June our little force of colored and white troops across
the Mississippi, at Milliken's Bend, were attacked by about 3,000 men
from Richard Taylor's trans-Mississippi command. With the aid of the
gunboats they were speedily repelled. I sent Mower's brigade over with
instructions to drive the enemy beyond the Tensas Bayou; and we had no
further trouble in that quarter during the siege. This was the first
important engagement of the war in which colored troops were under fire.
These men were very raw, having all been enlisted since the beginning of
the siege, but they behaved well.

On the 8th of June a full division arrived from Hurlbut's command, under
General Sooy Smith. It was sent immediately to Haines' Bluff, and
General C. C. Washburn was assigned to the general command at that
