Dec 18 1862. Rebel cavalry led by Nathan Forrest is creating great havoc behind our lines. I wrote Admiral Porter to attempt to gain his assistance in stopping him.
OXFORD, MISS., December 18, 1862.
Admiral PORTER, CAIRO, Ill.:
I am informed there is now four feet of water in the Tennessee. Gunboats there would be of immense value.
Forrest and Napier are now on this side of the river with from 5,000 to 10,000 men and have got near to Jackson.
I hope my force will be able to drive to the river. I have been concentrating troops all day to meet them.
