The difficulties of supplying your army, except when you are constantly moving, beyond where you are, I plainly see.

If it had not been for Price's movements Canby would have sent twelve thousand more men to Mobile.

From your command on the Mississippi an equal number could have been taken.

With these forces my idea would have been to divide them, sending one half to Mobile and the other half to Savannah.

You could then move as proposed in your telegram, so as to threaten Macon and Augusta equally.
Whichever was abandoned by the enemy you could take and open up a new base of supplies.
