enerals captured were brigadier-generals, Mackall and Gantt; the third
was perhaps L.M. Walker. When Major-General McCown was relieved on March
31st by Mackall, McCown and Brigadier-General Trudeau left.
Brigadier-General A.P. Stewart had left previously and reported for duty
at Corinth. Colonels Walker and Gantt were promoted brigadier-generals
after the siege began. General Walker appears, from his report of April
9th, dated St. Francis County, Arkansas, to have left on account of
ill-health some time before the surrender. The prisoners embraced,
including those on the island surrendered to the navy, seven regiments
and one battalion of infantry, one of the regiments having twelve
companies--eleven companies of heavy and one of light artillery, two
companies of cavalry, the officers and crews of the floating battery and
the steamboats, and laborers and employees.

The Mississippi was now open to Fort Pillow. General Halleck telegraphed
to General Pope: "I congratulate you and your command on your splendid
achievement. It exceeds in boldness and brilliancy all other operations
of the war. It will be memorable in military history, and will be
admired by future generations." On April 12th, General Pope and his
entire command embarked on transports and steamed down the river, in
company with the gunboat fleet. The force arrived in front of Fort
Pillow on the 14th. In a few days, before reconnoitring was completed,
Pope was ordered to report with his whole command, except two regiments
to be left with the gunboats, to General Halleck at Pittsburg Landing.

CHAPTER V.

THE GATHERING OF THE FORCES.

After the surrender of Fort Donelson, the force confronting Halleck was
the command of General Beauregard, stationed at Columbus, Island Number
Ten, at Forts Pillow and Randolph, at Memphis, and at convenient points
on the railroads in Mississippi. The next objective point that presented
itself was Memphis, and, as preliminary, the fortified points on the
river above it. But Memphis had large railway connections. The direct
road to Nashville was cut at its crossing over the Tennessee River, but
at Humboldt it intersected the Mobile and Ohio, which joined Columbus
with Mobile. The Memphis and Charleston, running nearly due east to
Chattanooga, also intersected the Mobile and Ohio at Corinth. The
Mississippi and Tennessee, in connection with the New Orleans, Jackson
and Great Northern, gave a route nearly due south to Ne
