l the
troops from his corps that our transports and barges could carry. About
10,000 men were so embarked. The plan was to have the navy silence the
guns at Grand Gulf, and to have as many men as possible ready to debark
in the shortest possible time under cover of the fire of the navy and
carry the works by storm. The following order was issued:

PERKINS PLANTATION, LA., April 27,1863.

MAJOR-GENERAL J. A. MCCLERNAND, Commanding 13th A. C.

Commence immediately the embarkation of your corps, or so much of it as
there is transportation for. Have put aboard the artillery and every
article authorized in orders limiting baggage, except the men, and hold
them in readiness, with their places assigned, to be moved at a moment's
warning.

All the troops you may have, except those ordered to remain behind, send
to a point nearly opposite Grand Gulf, where you see, by special orders
of this date, General McPherson is ordered to send one division.

The plan of the attack will be for the navy to attack and silence all
the batteries commanding the river. Your corps will be on the river,
ready to run to and debark on the nearest eligible land below the
promontory first brought to view passing down the river. Once on shore,
have each commander instructed beforehand to form his men the best the
ground will admit of, and take possession of the most commanding points,
but avoid separating your command so that it cannot support itself. The
first object is to get a foothold where our troops can maintain
themselves until such time as preparations can be made and troops
collected for a forward movement.

Admiral Porter has proposed to place his boats in the position indicated
to you a few days ago, and to bring over with them such troops as may be
below the city after the guns of the enemy are silenced.

It may be that the enemy will occupy positions back from the city, out
of range of the gunboats, so as to make it desirable to run past Grand
Gulf and land at Rodney. In case this should prove the plan, a signal
will be arranged and you duly informed, when the transports are to start
with this view. Or, it may be expedient for the boats to run past, but
not the men. In this case, then, the transports would have to be
brought back to where the men could land and move by forced marches to
below Grand Gulf, re-embark rapidly and proceed to the latter place.
There will be required, then, three signals; one, to indicate that the
