Halleck disapproved of my proposition to go against Mobile, so that I was obliged to settle down and see myself put again on the defensive as I had been a year before in west Tennessee.  It would have been an easy thing to capture Mobile at the time I proposed to go there.  Having that as a base of operations, troops could have been thrown into the interior to operate against General Bragg’s army.  This would necessarily have compelled Bragg to detach in order to meet this fire in his rear.  If he had not done this the troops from Mobile could have inflicted inestimable damage upon much of the country from which his army and Lee’s were yet receiving their supplies.  I was so much impressed with this idea that I renewed my request later in July and again about the 1st of August, and proposed sending all the troops necessary, asking only the assistance of the navy to protect the debarkation of troops at or near Mobile.  I also asked for a leave of absence to visit New Orleans, particularly if my suggestion to move against Mobile should be approved.  Both requests were refused.  So far as my experience with General Halleck went it was very much easier for him to refuse a favor than to grant one.  But I did not regard this as a favor.  It was simply in line of duty, though out of my department.

The General-in-chief having decided against me, the depletion of an army, which had won a succession of great victories, commenced, as had been the case the year before after the fall of Corinth when the army was sent where it would do the least good.  By orders, I sent to Banks a force of 4,000 men; returned the 9th corps to Kentucky and, when transportation had been collected, started a division of 5,000 men to Schofield in Missouri where Price was raiding the State.  I also detached a brigade under Ransom to Natchez, to garrison that place permanently.  This latter move was quite fortunate as to the time when Ransom arrived there.  The enemy happened to have a large number, about 5,000 head, of beef cattle there on the way from Texas to feed the Eastern armies, and also a large amount of munitions of war which had probably come through Texas from the Rio Grande and which were on the way to Lee’s and other armies in the East.

The troops that were left with me around Vicksburg were very busily and unpleasantly employed in making expeditions against guerilla bands and small detachments of cavalry which infested the interior, and in destroying mills, bridges and rolling stock on the railroads.  The guerillas and cavalry were not there to fight but to annoy, and therefore disappeared on the first approach of our troops.

The country back of Vicksburg was filled with deserters from Pemberton’s army and, it was reported, many from Johnston’s also.  The men determined not to fight again while the war lasted.  Those who lived beyond the reach of the Confederate army wanted to get to their homes.  Those who did not, wanted to get North where they could work for their support till the war was over.  Besides all this there was quite a peace feeling, for the time being, among the citizens of that part of Mississippi, but this feeling soon subsided.  It is not probable that Pemberton got off with over 4,000 of his army to the camp where he proposed taking them, and these were in a demoralized condition.
