On arriving in Burke's Garden, I found Colonel May, who ordered me to accompany him. After a short delay, he received intelligence that the enemy was moving toward the gap in the mountain above Crabtree's. We arrived at this road only in time to see their rear guard pass. After crossing the mountain, our advance guard charged the enemy's rear, and drove them upon the mein column. Upon arriving at Dill's, Colonel May called on me to charge the enemy. In the charge, we captured 7 of the enemy and 1 negro. We remained here until about 1 a. m., when we crossed the mountain, and pursued them into abb's Valley, where we came up with General Williams, with Peters' battalion, skirmishing with the enemy's rear. I suppose there were 300 men in his (Peters') battalion, and probably 200 in rear, under command of Colonel May. If they had any means of ascertaining which road they intended to come, the troops could have been posted so as to make them surrender or abandon the idea of passing through Abb's Valley.

Respectfully submitted.
