han it had done if under a thorough leader. I
said I wanted the very best man in the army for that command. Halleck
was present and spoke up, saying: "How would Sheridan do?" I replied:
"The very man I want." The President said I could have anybody I wanted.
Sheridan was telegraphed for that day, and on his arrival was assigned
to the command of the cavalry corps with the Army of the Potomac. This
relieved General Alfred Pleasonton. It was not a reflection on that
officer, however, for I did not know but that he had been as efficient
as any other cavalry commander.

Banks in the Department of the Gulf was ordered to assemble all the
troops he had at New Orleans in time to join in the general move, Mobile
to be his objective.

At this time I was not entirely decided as to whether I should move the
Army of the Potomac by the right flank of the enemy, or by his left.
Each plan presented advantages. (*25) If by his right--my left--the
Potomac, Chesapeake Bay and tributaries would furnish us an easy hauling
distance of every position the army could occupy from the Rapidan to the
James River. But Lee could, if he chose, detach or move his whole army
north on a line rather interior to the one I would have to take in
following. A movement by his left--our right--would obviate this; but
all that was done would have to be done with the supplies and ammunition
we started with. All idea of adopting this latter plan was abandoned
when the limited quantity of supplies possible to take with us was
considered. The country over which we would have to pass was so
exhausted of all food or forage that we would be obliged to carry
everything with us.

While these preparations were going on the enemy was not entirely idle.
In the West Forrest made a raid in West Tennessee up to the northern
border, capturing the garrison of four or five hundred men at Union
City, and followed it up by an attack on Paducah, Kentucky, on the banks
of the Ohio. While he was able to enter the city he failed to capture
the forts or any part of the garrison. On the first intelligence of
Forrest's raid I telegraphed Sherman to send all his cavalry against
him, and not to let him get out of the trap he had put himself into.
Sherman had anticipated me by sending troops against him before he got
my order.

Forrest, however, fell back rapidly, and attacked the troops at Fort
Pillow, a station for the protection of the navigation of the
Mississippi Rive
