supplies of hard bread, salt, sugar coffee; one day's pork, four days' fresh beef, 9,500, and five days' forage for your animals, the animals' [forage] being based upon the quantity you were about to take when the six days' [supplies] were loaded to start with on Monday last. This train, upon its arrival, should make you whole for the time lost by the storm, and leave you in fresh condition to carry on the operations with which you were intrusted. If the amount of supplies which you are advised will be sent is in excess of your requirement, please return notice to us as speedily as possible, and send out officers to meet the train and send what portion of it you do not need. The commanding general directs that you send out meet this train, and that it be unloaded and returned without delay.

The bearer is expected to return immediately with your reply, giving the field return and the condition of your supplies.

Copy of a dispatch to-day received from General Haupt is forwarded for your information. By this you will see that it will be impossible to repair the railroad in time to furnish you supplied by rail to Rappahannock Station.

The rations for the men are 50,000 rations, as mentioned herein, save bacon is substituted for pork.

Very respectfully, &c.,

S. WILLIAMS,

Assistant Adjutant-General.
