October 22nd.—Rain falling in torrents. As I write, in come reports of a battle last night, some forty miles up the river, which by signs and tokens I am led to believe was unfavourable to the Federals. They crossed the river intending to move upon Leesburg—were attacked by overwhelming forces and repulsed, but maintained themselves on the right bank till General Banks reinforced them and enabled them to hold their own. McClellan has gone or is going at once to the scene of action. It was three o’clock before I heard the news, the road and country were alike unknown, nor had I friend or acquaintance in the army of the Upper Potomac. My horse was brought round however, and in company with Mr. Anderson, I rode out of Washington along the river till the falling evening warned us to retrace our steps, and we returned in pelting rain as we set out, and in pitchy darkness, without meeting any messenger or person with news from the battle-field. Late at night the White House was placed in deep grief by the intelligence that in addition to other losses, Brigadier and Senator Baker of California was killed. The President was inconsolable, and walked up and down his room for hours lamenting the loss of his friend. Mrs. Lincoln’s grief was equally poignant. Before bed-time I told the German landlord to tell my servant I wanted my horse round at seven o’clock.
