While on one hand Bragg
had suffered defeat, he had on the other caused Buell
to give up all idea of moving into East Tennessee
, an object on which the President
had specially and repeatedly insisted.
specifically ordered Buell
to resume and execute that plan, Buell
urged such objections, and intimated such unwillingness, that on October 24, 1862, he was relieved from command, and General Rosecrans
was appointed to succeed him. Rosecrans
neglected the East Tennessee
orders as heedlessly as Buell
had done; but, reorganizing the Army of the Cumberland and strengthening his communications, marched against Bragg
, who had gone into winter quarters at Murfreesboro
The severe engagement of that name, fought on December 31, 1862, and the three succeeding days of the new year, between forces numbering about forty-three thousand on each side, was tactically a drawn battle, but its results rendered it an important Union victory, compelling Bragg
to retreat; though, for reasons which he never satisfactorily explained, Rosecrans
failed for six months to follow up his evident advantages.
The transfer of Halleck
from the West
in the summer of 1862, left Grant
in command of the district of West Tennessee.
's eastward expedition left him so few movable troops that during the summer and most of the autumn he was able to accomplish little except to defend his department by the repulse of the enemy at Iuka
in September, and at Corinth
early in October, Rosecrans
being in local command at both places.
It was for these successes that Rosecrans
was chosen to succeed Buell
had doubtless given much of his enforced leisure to studying the great problem of opening the Mississippi
, a task which was thus left in his own
