ourselves of. With Fort Henry in our hands
we had a navigable stream open to us up to Muscle Shoals, in Alabama.
The Memphis and Charleston Railroad strikes the Tennessee at Eastport,
Mississippi, and follows close to the banks of the river up to the
shoals. This road, of vast importance to the enemy, would cease to be
of use to them for through traffic the moment Fort Henry became ours.
Fort Donelson was the gate to Nashville--a place of great military and
political importance--and to a rich country extending far east in
Kentucky. These two points in our possession the enemy would
necessarily be thrown back to the Memphis and Charleston road, or to the
boundary of the cotton states, and, as before stated, that road would be
lost to them for through communication.

The designation of my command had been changed after Halleck's arrival,
from the District of South-east Missouri to the District of Cairo, and
the small district commanded by General C. F. Smith, embracing the
mouths of the Tennessee and Cumberland rivers, had been added to my
jurisdiction. Early in January, 1862, I was directed by General
McClellan, through my department commander, to make a reconnoissance in
favor of Brigadier-General Don Carlos Buell, who commanded the
Department of the Ohio, with headquarters at Louisville, and who was
confronting General S. B. Buckner with a larger Confederate force at
Bowling Green. It was supposed that Buell was about to make some move
against the enemy, and my demonstration was intended to prevent the
sending of troops from Columbus, Fort Henry or Donelson to Buckner. I
at once ordered General Smith to send a force up the west bank of the
Tennessee to threaten forts Heiman and Henry; McClernand at the same
time with a force of 6,000 men was sent out into west Kentucky,
threatening Columbus with one column and the Tennessee River with
another. I went with McClernand's command. The weather was very bad;
snow and rain fell; the roads, never good in that section, were
intolerable. We were out more than a week splashing through the mud,
snow and rain, the men suffering very much. The object of the
expedition was accomplished. The enemy did not send reinforcements to
Bowling Green, and General George H. Thomas fought and won the battle of
Mill Springs before we returned.

As a result of this expedition General Smith reported that he thought it
practicable to capture Fort Heiman. This fort stood on high ground,
