Red River is very low for the season, and I doubt if any of the boats can pass the falls or rapids at Alexandria.

What General Banks proposes to do in that event I do not know; but my own judgment is that Shreveport ought not to be attacked until the gunboats can reach it.

Not that a force marching by land cannot do it alone, but it would be bad economy in war to invest the place with an army so far from heavy guns, mortars, ammunition, and provisions, which can alone reach Shreveport by water.

Still, I do not know about General Banks's plans in that event; and whatever they may be, your duty will be to conform, in the most hearty manner.
My understanding with General Banks is that he will not need the cooperation of your force beyond thirty days from the date you reach Red River.

As soon as he has taken Shreveport, or as soon as be can spare you, return to Vicksburg with all dispatch, gather up your detachments, wagons, tents, transportation, and all property pertaining to so much of the command as belongs to the Sixteenth Army Corps, and conduct it to Memphis, where orders will await you.
My present belief is your division, entire, will be needed with the Army of the Tennessee, about Huntsville or Bridgeport.
