The following just received from General Ferrero:

I have to report that Captain Andrews, in command of cavalry pickets in our front (Gurley house), states that the enemy attacked his line again at sundown and drove him back one-quarter of a mile, where he now is, and that it was infantry that made the attack. I have established a strong picket of infantry in rear of the cavalry and ordered my division in line of battle before sunrise in the morning.

The enemy also advanced his vedettes to this edge of the corn-field in front of the Third Division this evening.
