under Colonel W. J. Palmer, 15th
Pennsylvania Volunteers, continued to follow Hood for some distance,
capturing considerable transportation and all the enemy's
pontoon-bridge. The details of these operations will be found
clearly set forth in General Thomas's report.

A cavalry expedition, under Brevet Major-General Grierson, started from
Memphis on the 21st of December. On the 25th he surprised and captured
Forrest's dismounted camp at Verona, Mississippi, on the Mobile and Ohio
Railroad, destroyed the railroad, sixteen cars loaded with wagons and
pontoons for Hood's army, four thousand new English carbines, and large
amounts of public stores. On the morning of the 28th he attacked and
captured a force of the enemy at Egypt, and destroyed a train of
fourteen cars; thence turning to the south-west, he struck the
Mississippi Central Railroad at Winona, destroyed the factories and
large amounts of stores at Bankston, and the machine-shops and public
property at Grenada, arriving at Vicksburg January 5th.

During the operations in Middle Tennessee, the enemy, with a force under
General Breckinridge, entered East Tennessee. On the 13th of November
he attacked General Gillem, near Morristown, capturing his artillery and
several hundred prisoners. Gillem, with what was left of his command,
retreated to Knoxville. Following up his success, Breckinridge moved to
near Knoxville, but withdrew on the 18th, followed by General Ammen.
Under the directions of General Thomas, General Stoneman concentrated
the commands of Generals Burbridge and Gillem near Bean's Station to
operate against Breckinridge, and destroy or drive him into Virginia
--destroy the salt-works at Saltville, and the railroad into Virginia
as far as he could go without endangering his command. On the 12th of
December he commenced his movement, capturing and dispersing the enemy's
forces wherever he met them. On the 16th he struck the enemy, under
Vaughn, at Marion, completely routing and pursuing him to Wytheville,
capturing all his artillery, trains, and one hundred and ninety-eight
prisoners; and destroyed Wytheville, with its stores and supplies, and
the extensive lead-works near there. Returning to Marion, he met a force
under Breckinridge, consisting, among other troops, of the garrison of
Saltville, that had started in pursuit. He at once made arrangements to
attack it the next morning; but morning found Breckinridge gone. He
then moved directly to
