Chapter 14
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.
