Besides, there was great danger, always in my mind, that Forrest would collect a heavy cavalry command in Mississippi, cross the Tennessee River, and break up our railroad below Nashville.

In anticipation of this very danger, I had sent General Sturgis to Memphis to take command of all the cavalry in that quarter, to go out toward Pontotoc, engage Forrest and defeat him; but on the 14th of June I learned that General Sturgis had himself been defeated on the 10th of June, and had been driven by Forrest back into Memphis in considerable confusion.

I expected that this would soon be followed by a general raid on all our roads in Tennessee.

General G.J.Smith, with the two divisions of the Sixteenth and Seventeenth Corps which had been with General Banks up Red River, had returned from that ill-fated expedition, and had been ordered to General Canby at New Orleans, who was making a diversion about Mobile; but, on hearing of General Sturgis's defeat, I ordered General Smith to go out from Memphis and renew the offensive, so as to keep Forrest off our roads.

This he did finally, defeating Forrest at Tupelo, on the 13th, 14th, and 15th days of July; and he so stirred up matters in North Mississippi that Forrest could not leave for Tennessee.
