e capture of Forts Henry and Donelson compelled a change in the
Confederate line of defense. General Albert Sidney Johnston withdrew
from Bowling Green to Nashville, but fell back again upon learning of
the fall of Fort Donelson, and assumed position near Murfreesboro',
Tennessee. All the northern part of that State, including the Cumberland
River, was given up by the Confederates, and, when the new line was
established, the centre was held by Beauregard at Jackson, the left by
Polk at New Madrid, and the right by Johnston at Murfreesboro'. Thus the
Confederates were driven out of Kentucky and the northern part of
Tennessee. It was a serious check for the Confederacy.

CAPTURE OF ISLAND NO. 10.

General Grant gave the enemy no rest. In order to retain possession of
Island No. 10, it was necessary for them to hold the outpost of New
Madrid. In the latter part of February, General Pope led an expedition
against that place, while Commodore Foote made a demonstration in front
with his gunboats. Through cold and storm the Unionists bravely pushed
their way, and the garrison of New Madrid were compelled to take refuge
on Island No. 10, and in the works on the Kentucky side of the river.
Operations were then begun against Island No. 10. By digging a canal
twelve miles long, which permitted the gunboats to pass around the
defenses, and by energetic operations in all directions, the Confederate
position was rendered untenable, and the post, with a large amount of
war material, was surrendered to Commodore Foote.

Meanwhile, General Grant, after the occupation of Nashville, went down
the Tennessee River to Pittsburg Landing, while General Buell, with the
other portion of the Union army, started for the same point by land.
Aware of this division of the Federal forces, General Albert Sidney
Johnston hastily concentrated his own divisions with the intention of
crushing the two Union armies before they could unite. When Johnston
arrived in the vicinity of Pittsburg Landing on the 3d of April he had
40,000 men, divided into three corps and a reserve.

BATTLE OF PITTSBURG LANDING.

Pittsburg Landing, or Shiloh, as it is called in the South, consists of
a high bluff, a half-mile in extent, where General W.T. Sherman had been
ordered to take position and prepare for the arrival of 100,000 men.
Grant was not prepared for the unexpected attack. Buell was some
distance away with 40,000 troops, and the Union commander had a somewhat
