Before Vicksburg Feby 7. 1863
You will proceed without delay to Helena Ark and there take in tow a Barge of Coal, applying to Genl Gorman for the same and return to Delta Miss with it
At Delta you will remain until the arrival of four Gun Boats that have been designated by the Admiral when you will divide your force, and send them aboard the Gun Boats, the number on each to be determined by the Navy department.
As soon as the expedition proceeds you will discharge the Transport on which you ascended the river and direct her to return the empty Coal barge to Helena, and then return to this fleet herself.
Full directions have been given the Navy Department for their guidance on this Expedition
The Infantry go to act as Marines for the occasion The troops will be under the immediate command of their own Officers, but in no instance are they to exercise control over the vessels or dictate when they are to go or what do.
