hio had been started some time before on its march eastward toward
Chattanooga; and as this movement would be followed of course by a
manoeuvre on the part of the enemy, now at Tupelo under General
Braxton Bragg, either to meet Buell or frustrate his designs by some
counter-operation, I was expected to furnish, by scouting and all
other means available, information as to what was going on within the
Confederate lines. To do the work required, necessitated an increase
of my command, and the Seventh Kansas Cavalry was therefore added to
it, and my picket-line extended so as to cover from Jacinto
southwesterly to a point midway between Rienzi and Booneville, and
then northwesterly to the Hatchie River. Skirmishes between outposts
on this line were of frequent occurrence, with small results to
either side, but they were somewhat annoying, particularly in the
direction of Ripley, where the enemy maintained a considerable
outpost. Deciding to cripple if not capture this outpost, on the
evening of July 27, I sent out an expedition under Colonel Hatch,
which drove the enemy from the town of Ripley and took a few
prisoners, but the most valuable prize was in the shape of a package
of thirty-two private letters, the partial reading of which disclosed
to me the positive transfer from Mississippi of most of Bragg's army,
for the purpose of counteracting Buell's operations in northern
Alabama and East Tennessee. This decisive evidence was of the utmost
importance, and without taking time to read all the letters, I
forwarded them to General Granger July 28, in a despatch which
stated: "I deem it necessary to send them at once; the enemy is
moving in large force on Chattanooga." Other than this the results
of the expedition were few; and the enemy, having fled from Ripley
with but slight resistance, accompanied by almost all the
inhabitants, re-occupied the place next day after our people had
quitted it, and resumed in due time his annoying attacks on our
outposts, both sides trying to achieve something whenever occasion
offered.
The prevalence of a severe drought had resulted in drying up many of
the streams within the enemy's lines, and, in consequence, he was
obliged to shift his camps often, and send his beef-cattle and mules
near his outposts for water. My scouts kept me well posted in regard
to the movements of both camps and herds; and a favorable opportunity
presenting itself, I sent an expedition on August 14 to gathe
