Unknown to Brigadier-General GRIFFIN, December 13, 1862

December 13, 1862—1 p. m.

Brigadier-General GRIFFIN, Oommanding First Division :

In compliance with orders from the major-general commanding the center grand division, the corps will march at once across the river to Fredericksburg by the right, left, and center bridges, as heretofore ordered. The march must be as rapid as possible without over-fatiguing the troops previous to engaging. General Sykes will keep to the right, to avoid any collision or stoppage of General Humphreys’ column. ‘The troops must be cautioned to be sparing of their ammunition, fire low, and by volleys. Let the Fifth Corps to-day do its whole duty faithfully and fearlessly, and all will be well. This corps will move to the support of General Sumner’s grand division or for reserve, as the case may be.

The dispositions, unless otherwise directed, after leaving the town, will be as heretofore ordered—Sykes’ division the right, Griffin’s the left, Humphreys’ the center. If but two divisions are ordered forward, Griffin’s and Humphreys’ will advance, Sykes’ in reserve. If but one

division, Griffin will lead. [DANL. BUTTERFIELD, Brigadier-General.

HEADQUARTERS T’irtH ARMY CORPS, Willcox’s Headquarters, December 13, 1862—3.12 p. m.

GENERAL: In compliance with your permission, I have sent Griffin to support Sturgis. Let some one meet him on the street I left you in and conduct him. Humphreys, in compliance with orders from your engineer officers, has been sent six squares up, right and front, Hains, engineer, conducting him. Had I better cross Sykes or keep him on the other side until Humphreys is out of the way, and the streets more clear?

Very respectfully, yours
