August 1st.—Hot and clear; but it rained yesterday three-quarters of an hour in the afternoon.

Our loss in the affair at Petersburg is about 800, the enemy’s 3500. We captured 2000 small arms.

We have nothing yet from Atlanta, but no doubt there has been another battle. I hope no disaster has befallen us there. No doubt the wires have been cut by the raiders, and roads also. It is a critical time in Georgia. But if Virginia triumphs over the assaults of Grant, all will go well.

August 2d.—Bright and hot. At 4 p.m. a cloud rising. Fear my wife, and daughter Fannie, and Custis (who has a days’ furlough), who went this morning per Fredericksburg Railroad into Hanover County to gather blackberries, will be caught in a rain. Nevertheless, the rain is wanted.

Gen. Lee writes that he had directed Morgan to co-operate with Early, but he was sick.
