General D. P. WOODBURY,

The following order of march for pontoon trains is proposed for tonight, to prevent confusion: Spaulding's trains for two upper bridges to move by Phillips house across railroad to Lacy house: the other three trains, Cross leading, then Magruder's and last Spaulding's, lower bridge, to move to position by turning to the left from the suspension bridge road a little beyond the Wallace house. Chiefs of grand divisions wish to get at bridges one or two bays of bridge flooring to take with them, and two men with each bay to attend to lashings.

Very respectfully,

C. B. COMSTOCK,

Lieutenant of Engineers and Chief Engineer Army of the Potomac.

You will move your bridge equipage from its present position so as to arrive at the place where the bridge is to be thrown at 3 a. m. to-morrow.

You are authorized to confer with the commander of the batteries as to opening fire if the enemy's fire should be too hot.
