t of the enemy's cavalry appeared in force about Allatoona
and the Etowah bridge, when I became fully convinced that Hood had
sent all of his cavalry to raid upon our railroads. For some days
our communication with Nashville was interrupted by the destruction
of the telegraph-lines, as well as railroad. I at once ordered
strong reconnoissances forward from our flanks on the left by
Garrard, and on the right by Kilpatrick. The former moved with so
much caution that I was displeased; but Kilpatrick, on the
contrary, displayed so much zeal and activity that I was attracted
to him at once. He reached Fairburn Station, on the West Point
road, and tore it up, returning safely to his position on our right
flank. I summoned him to me, and was so pleased with his spirit
and confidence, that I concluded to suspend the general movement of
the main army, and to send him with his small division of cavalry
to break up the Macon road about Jonesboro, in the hopes that it
would force Hood to evacuate Atlanta, and that I should thereby not
only secure possession of the city itself, but probably could catch
Hood in the confusion of retreat; and, further to increase the
chances of success.

I ordered General Thomas to detach two brigades of Garrard's
division of cavalry from the left to the right rear, to act as a
reserve in support of General Kilpatrick. Meantime, also, the
utmost activity was ordered along our whole front by the infantry
and artillery. Kilpatrick got off during the night of the 18th,
and returned to us on the 22d, having made the complete circuit of
Atlanta. He reported that he had destroyed three miles of the
railroad about Jonesboro, which he reckoned would take ten days to
repair; that he had encountered a division of infantry and a
brigade of cavalry (Ross's); that he had captured a battery and
destroyed three of its guns, bringing one in as a trophy, and he
also brought in three battle-flags and seventy prisoners. On the
23d, however, we saw trains coming into Atlanta from the south,
when I became more than ever convinced that cavalry could not or
would not work hard enough to disable a railroad properly, and
therefore resolved at once to proceed to the execution of my
original plan. Meantime, the damage done to our own railroad and
telegraph by Wheeler, about Resaca and Dalton, had been repaired,
and Wheeler himself was too far away to be of any service to his
own army, and where he could not do us muc
