A coolish, cloudy day. Wrote letters to Mother and Lucy. Nothing definite from the battlefield. Rumors of good and bad. Many complaints of McDowell; that he let Jackson slip off by withdrawing a division from an important point. On the whole, the result seems to be a draw yet. Our army in great strength, rumor says two hundred thousand, is on this side of the old Bull Run battlefield; the enemy one hundred and eighty thousand strong on the identical ground. No firing today until about 5:30 or 6 o'clock when there was a grand uproar until after dark near the old place, possibly further north; rumored or conjectured to be an attempt to our right. A thunderstorm came on about the same time when there was a fierce rivalry between the artillery of earth and heaven, the former having a decided advantage. A fierce storm of wind and rain all night, blowing down some tents and shaking all in a threatening way. About 9 P. M. received orders from brigade headquarters to be especially vigilant and to have the men ready to form line of battle without confusion. All which was done.
