repaired and
planked the railroad-bridge, and at daylight the army passed over
the Hiawassee and marched to Athens, fifteen miles. I had supposed
rightly that General Granger was about the mouth of the Hiawassee,
and had sent him notice of my orders; that General Grant had sent
me a copy of his written instructions, which were full and
complete, and that he must push for Kingston, near which we would
make a junction. But by the time I reached Athens I had better
studied the geography, and sent him orders, which found him at
Decatur, that Kingston was out of our way; that he should send his
boat to Kingston, but with his command strike across to
Philadelphia, and report to me there. I had but a small force of
cavalry, which was, at the time of my receipt of General Grant's
orders, scouting over about Benton and Columbus. I left my aide,
Major McCoy, at Charleston, to communicate with this cavalry and
hurry it forward. It overtook me in the night at Athens.

On the 2d of December the army moved rapidly north toward Loudon,
twenty-six miles distant. About 11 a.m., the cavalry passed to the
head of the column, was ordered to push to London, and, if
possible, to save a pontoon-bridge across the Tennessee, held by a
brigade of the enemy commanded by General Vaughn. The cavalry
moved with such rapidity as to capture every picket; but the
brigade of Vaughn had artillery in position, covered by earthworks,
and displayed a force too respectable to be carried by a cavalry
dash, so that darkness closed in before General Howard's infantry
got up. The enemy abandoned the place in the night, destroying the
pontoons, running three locomotives and forty-eight cars into the
Tennessee River, and abandoned much provision, four guns, and other
material, which General Howard took at daylight. But the bridge
was gone, and we were forced to turn east and trust to General
Burnside's bridge at Knoxville. It was all-important that General
Burnside should have notice of our coming, and but one day of the
time remained.

Accordingly, at Philadelphia, during the night of the 2d of
December, I sent my aide (Major Audenried) forward to Colonel Long,
commanding the brigade of cavalry at London, to explain to him how
all-important it was that notice of our approach should reach
General Burnside within twenty-four hours, ordering him to select
the best materials of his command, to start at once, ford the
Little Tennessee, and push into Knox
