formed, 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
transports can run down and debark the troops at Grand Gulf; one, that
the transports can run by without the troops; and the last, that the
transports can run by with the troops on board.

Should the men have to march, all baggage and artillery will be left to
run the blockade.

If not already directed, require your men to keep three days' rations in
their haversacks, not to be touched until a movement commences.

U. S. GRANT, Major-General.

At 8 o'clock A.M., 29th, Porter made the attack with his entire strength
present, eight gunboats. For nearly five and a half hours the attack
was kept up without silencing a single gun of the enemy. All this time
McClernand's 10,000 men were huddled together on the transports in the
stream ready to attempt a landing if signalled. I occupied a tug from
which I could see the effect of the battle on both sides, within range
of the enemy's guns; but a small tug, without armament, was not
calculated to attract the fire of batteries while they were being
assailed themselves. About half-past one the fleet withdrew, seeing
their efforts were entirely unavailing. The enemy ceased firing as soon
as we withdrew. I immediately signalled the Admiral and went aboard his
ship. The navy lost in this engagement eighteen killed and fifty-six
wounded. A large proportion of these were of the crew of the flagship,
and most of those from a single shell which penetrated the ship's side
and exploded between decks where the men were working their guns. The
sight of the mangled and dying men which met my eye as I boarded the
ship was sickening.

Grand Gulf is on a high bluff where the river runs at the very foot of
it. It is as defensible upon its front as Vicksburg and, at that time,
would have been just as impossible to capture by a front attack. I
therefore requested Porter to run the batteries with his fleet that
night, and to take charge of the transports, all of which would be
wanted below.

There is a long tongue of land from the Louisiana side extending towards
Grand Gulf, made by the river runnin
