Buford's cavalry had a long and desperate encounter, hand to hand, with the enemy, in which he drove handsomely before him very superior forces. Over 200 prisoners were captured and one battle flag. The troops are in splendid spirits, and are entitled to the highest praise for their distinguished conduct.

We had splendid fighting yesterday, and I think it will prevent Stuart making his raid, which he was to have commenced this morning. Toward night they opened 20-pounder Parrott guns at a long distance, showing they were re-enforced. They did not attempt to covered themselves with glory. We captured Stuart's camp, with his orders, letters, &c. He was to move to Maryland with 12, 000 cavalry and twenty-five guns, and he was camped at the ford we crossed, a perfect hornet's nest, but we drove them over 2 miles before Gregg came up, and, when I found out he had as hard a time as ourselves, and no fresh troops to call on, I returned to the north bank of the Rappahannock. The enemy lost very heavily. Buford's loss is 250 wounded. Killed not yet known. At least a doyen officers among the latter. I don't know Gregg's loss yet. * Gregg lost two guns before he joined me, but they were lost with honor; all his people were engaged, and his battery was without support. The battery men fought their pieces until cut down at their side. One gun in the same battery burst-Sixth New York. We blew up a caisson for the enemy, and killed a number. Tell the general I will send in a report to-day, as soon as I can collect the facts.

I also inclose the strength of the command at the battle, and as it was this morning on review. My detailed report. with those of subordinate commanders, will be forwarded as soon as it can be prepared. I cannot, however, refrain from saying at this time that the Cavalry Corps, by its brilliant con
