atest and most authentic information from naval officers
now there, to land our whole force on the Mississippi side, and
then to reach the point where the Vicksburg & Jackson Railroad
crosses the Big Black (f); after which to attack Vicksburg by land,
while the gun-boats assail it by water. It may be necessary
(looking to Grant's approach), before attacking Vicksburg, to
reduce the battery at Haine's Bluff first, so as to enable some of
the lighter gunboats and transports to ascend the Yazoo and
communicate with General Grant. The detailed manner of
accomplishing all these results will be communicated in due season,
and these general points are only made known at this time, that
commanders may study the maps, and also that in the event of
non-receipt of orders all may act in perfect concert by following
the general movement, unless specially detached.

You all now have the same map, so that no mistakes or confusion
need result from different names of localities. All possible
preparations as to wagons, provisions, axes, and intrenching-tools,
should be made in advance, so that when we do land there will be no
want of them. When we begin to act on shore, we must do the work
quickly and effectually. The gunboats under Admiral Porter will do
their full share, and I feel every assurance that the army will not
fall short in its work.

Division commanders may read this to regimental commanders, and
furnish brigade commanders a copy. They should also cause as many
copies of the map to be made on the same scale as possible, being
very careful in copying the names.

The points marked e and g (Allan's and Mount Albans) are evidently
strategical points that will figure in our future operations, and
these positions should be well studied.

I am, with great respect, your obedient servant,

W. T. SHERMAN, Major-General.

The Mississippi boats were admirably calculated for handling
troops, horses, guns, stores, etc., easy of embarkation and
disembarkation, and supplies of all kinds were abundant, except
fuel. For this we had to rely on wood, but most of the wood-yards,
so common on the river before the war, had been exhausted, so that
we had to use fence-rails, old dead timber, the logs of houses,
etc. Having abundance of men and plenty of axes, each boat could
daily procure a supply.

In proceeding down the river, one or more of Admiral Porter's
gunboats took the lead; others were distributed throughout the
column
