was that Shreveport should be taken at the earliest
possible day, and that if he found that the taking of it would occupy
from ten to fifteen days' more time than General Sherman had given his
troops to be absent from their command, he would send them back at the
time specified by General Sherman, even if it led to the abandonment of
the main object of the Red River expedition, for this force was
necessary to movements east of the Mississippi; that should his
expedition prove successful, he would hold Shreveport and the Red River
with such force as he might deem necessary, and return the balance of
his troops to the neighborhood of New Orleans, commencing no move for
the further acquisition of territory, unless it was to make that then
held by him more easily held; that it might be a part of the spring
campaign to move against Mobile; that it certainly would be, if troops
enough could be obtained to make it without embarrassing other
movements; that New Orleans would be the point of departure for such an
expedition; also, that I had directed General Steele to make a real move
from Arkansas, as suggested by him (General Banks), instead of a
demonstration, as Steele thought advisable.

On the 31st of March, in addition to the foregoing notification and
directions, he was instructed as follows:

"1st. If successful in your expedition against Shreveport, that you
turn over the defence of the Red River to General Steele and the navy.

"2d. That you abandon Texas entirely, with the exception of your hold
upon the Rio Grande. This can be held with four thousand men, if they
will turn their attention immediately to fortifying their positions. At
least one-half of the force required for this service might be taken
from the colored troops.

"3d. By properly fortifying on the Mississippi River, the force to
guard it from Port Hudson to New Orleans can be reduced to ten thousand
men, if not to a less number. Six thousand more would then hold all the
rest of the territory necessary to hold until active operations can
again be resumed west of the river. According to your last return, this
would give you a force of over thirty thousand effective men with which
to move against Mobile. To this I expect to add five thousand men from
Missouri. If however, you think the force here stated too small to hold
the territory regarded as necessary to hold possession of, I would say
concentrate at least twenty-five thousand men of you
