at Milliken's Bend, about ten miles above the mouth of the Yazoo,
Admiral Porter remaining with his gunboats at the Yazoo. General
John A. McClernand was in chief command, General George W. Morgan
commanded the First Corps and I the Second Corps of the Army of the
Mississippi.

I had learned that a small steamboat, the Blue Wing, with a mail,
towing coal-barges and loaded with ammunition, had left Memphis for
the Yazoo, about the 20th of December, had been captured by a rebel
boat which had come out of the Arkansas River, and had been carried
up that river to Fort Hind.

We had reports from this fort, usually called the "Post of
Arkansas," about forty miles above the mouth, that it was held by
about five thousand rebels, was an inclosed work, commanding the
passage of the river, but supposed to be easy of capture from the
rear. At that time I don't think General McClernand had any
definite views or plays of action. If so, he did not impart them
to me. He spoke, in general terms of opening the navigation of the
Mississippi, "cutting his way to the sea," etc., etc., but the
modus operandi was not so clear. Knowing full well that we could
not carry on operations against Vicksburg as long as the rebels
held the Post of Arkansas, whence to attack our boats coming and
going without convoy, I visited him on his boat, the Tigress, took
with me a boy who had been on the Blue Wing, and had escaped, and
asked leave to go up the Arkansas, to clear out the Post. He made
various objections, but consented to go with me to see Admiral
Porter about it. We got up steam in the Forest Queen, during the
night of January 4th, stopped at the Tigress, took General
McClernand on board, and proceeded down the river by night to the
admiral's boat, the Black Hawk, lying in the mouth of the Yazoo.
It must have been near midnight, and Admiral Porter was in
deshabille. We were seated in his cabin and I explained my views
about Arkansas Post, and asked his cooperation. He said that he
was short of coal, and could not use wood in his iron-clad boats.
Of these I asked for two, to be commanded by Captain Shirk or
Phelps, or some officer of my acquaintance. At that moment, poor
Gwin lay on his bed, in a state-room close by, dying from the
effect of the cannon shot received at Haines's Bluff, as before
described. Porter's manner to McClernand was so curt that I
invited him out into a forward-cabin where he had his charts, and
as
