Feb 16 1863. I have written Gen. Halleck to give him a report on our progress through the Yazoo pass.
HEADQUARTERS DEPARTMENT OF THE TENNESSEE,
Before Vicksburg, MISS., February 16, 1863.
Respectfully forwarded to the Headquarters of the Army, Washington, for the information of the General-in-Chief. There is a force now diligently at work clearing out Yazoo Pass, and four light-draught gunboats (one iron-clad) with the party. I am also sending an additional DIVISION of infantry, with a few pieces of artillery, without horses, to accompany the expedition. If successful, they will clear out the Yazoo and all tributaries of all vessels that can do us any injury, saving them for the Government, if possible, or as many of them as possible. The first attempt will be to ascend the Yalabusha to Grenada and destroy the railroad bridges there. The force now at Grenada is not large.
