General Halleck commenced his efforts in all quarters to get
reinforcements to forward to me immediately on my departure from Cairo.
General Hunter sent men freely from Kansas, and a large division under
General Nelson, from Buell's army, was also dispatched. Orders went out
from the War Department to consolidate fragments of companies that were
being recruited in the Western States so as to make full companies, and
to consolidate companies into regiments. General Halleck did not
approve or disapprove of my going to Fort Donelson. He said nothing
whatever to me on the subject. He informed Buell on the 7th that I
would march against Fort Donelson the next day; but on the 10th he
directed me to fortify Fort Henry strongly, particularly to the land
side, saying that he forwarded me intrenching tools for that purpose. I
received this dispatch in front of Fort Donelson.

I was very impatient to get to Fort Donelson because I knew the
importance of the place to the enemy and supposed he would reinforce it
rapidly. I felt that 15,000 men on the 8th would be more effective than
50,000 a month later. I asked Flag-officer Foote, therefore, to order
his gunboats still about Cairo to proceed up the Cumberland River and
not to wait for those gone to Eastport and Florence; but the others got
back in time and we started on the 12th. I had moved McClernand out a
few miles the night before so as to leave the road as free as possible.

Just as we were about to start the first reinforcement reached me on
transports. It was a brigade composed of six full regiments commanded
by Colonel Thayer, of Nebraska. As the gunboats were going around to
Donelson by the Tennessee, Ohio and Cumberland rivers, I directed Thayer
to turn about and go under their convoy.

I started from Fort Henry with 15,000 men, including eight batteries and
part of a regiment of cavalry, and, meeting with no obstruction to
detain us, the advance arrived in front of the enemy by noon. That
afternoon and the next day were spent in taking up ground to make the
investment as complete as possible. General Smith had been directed to
leave a portion of his division behind to guard forts Henry and Heiman.
He left General Lew. Wallace with 2,500 men. With the remainder of his
division he occupied our left, extending to Hickman creek. McClernand
was on the right and covered the roads running south and south-west from
Dover. His right extended to the back-w
