urtis, for cooperation. I
suggested to him that if he would request General Curtis to send an
expedition from some point on the Mississippi, near Helena, then
held in force, toward Grenada, to the rear of Pemberton, it would
alarm him for the safety of his communications, and would assist us
materially in the proposed attack on his front. He authorized me
to send to the commanding officer at Helena a request to that
effect, and, as soon as I reached Memphis, I dispatched my aide,
Major McCoy, to Helena, who returned, bringing me a letter from
General Frederick Steele, who had just reached Helena with
Osterhaus's division, and who was temporarily in command, General
Curtis having gone to St. Louis. This letter contained the
assurance that he "would send from Friar's Point a large force
under Brigadier-General A. P. Hovey in the direction of Grenada,
aiming to reach the Tallahatchie at Charleston, on the next Monday,
Tuesday, or Wednesday (December 1st) at furthest." My command was
appointed to start on Wednesday, November 24th, and meantime
Major-General S. A. Hurlbut, having reported for duty, was assigned
to the command of Memphis, with four regiments of infantry one
battery of artillery, two companies of Thielman's cavalry and the
certain prospect of soon receiving a number of new regiments, known
to be en route.

I marched out of Memphis punctually with three small divisions,
taking different roads till we approached the Tallahatchie, when we
converged on Wyatt to cross the river, there a bold, deep stream,
with a newly-constructed fort behind. I had Grierson's Sixth
Illinois Cavalry with me, and with it opened communication with
General Grant when we were abreast of Holly Springs. We reached
Wyatt on the 2d day of December without the least opposition, and
there learned that Pemberton's whole army had fallen back to the
Yalabusha near Grenada, in a great measure by reason of the
exaggerated reports concerning the Helena force, which had reached
Charleston; and some of General Hovey's cavalry, under General
Washburn, having struck the railroad in the neighborhood of
Coffeeville, naturally alarmed General Pemberton for the safety of
his communications, and made him let go his Tallahatchie line with
all the forts which he had built at great cost in labor. We had to
build a bridge at Wyatt, which consumed a couple of days, and on
the 5th of December my whole command was at College Hill, ten miles
from Oxford,
