ordered to Fredericksburg, and that not over 20 rebel cavalry had lately occupied Madison Court-House. A small force of infantry is said to be between Jack's Shop and Liberty Mills, at which former point an enrolling officer is located.

I order the post-office at Madison Court-House to be forced, and the mail seized, but found nothing of importance except some late newspapers. The command remained two hours at Madison Court-House, returning to camp at 5 p. m., after stopping one and one-half hours at James City to feed and cook. Two prisoners of Tenth Virginia Cavalry (Fitzhugh Lee's brigade) were captured, together with their arms, horses, and equipments. Three conscripts, en route to the enrolling officer, were also captured. One citizen, charged with being found doing picket duty, armed, &c., was also brought in. *
