tomac to do
so. More specific written instructions were not given, for the reason
that I had talked over with him the plans of the campaign, and was
satisfied that he understood them and would execute them to the fullest
extent possible.

Major-General N. P. Banks, then on an expedition up Red River against
Shreveport, Louisiana (which had been organized previous to my
appointment to command), was notified by me on the 15th of March, of the
importance it 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

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

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

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 terri
