Cloudy and raining. All is quiet. Few soldiers seen on the streets until after breakfast, when the advancing corps of Gen. Johnston appears with waving flags and stirring music, as they approach the public square. Three cheers went up for the Southern Confederacy. They passed on column after column, for hours. Next their batteries, army wagons, and ambulances, presenting a fearful sight. I have mixed feelings of indignation and humility. The passage of the army created a consternation among the people. Many feel all is lost, after seeing this show of power in the face of our inadequate defense. At about three o'clock, the rear of Johnston's corps is passed, making about 15,000 men, rank and file, 72 pieces of ordinance, 350 wagons, about a regiment is left to guard the town. The large school building has been taken by them for a hospital. Requisitions have been made on all the innkeepers for mattresses, blankets, quilts, sheets, etc. for the Rebel sick and wounded. It is expected the like orders will be given the citizens. This evening a part of their army has advanced near the town on the Baltimore Pike, and on the Western Pike, occupying the fairground. They say they have entered upon a desperate enterprise,and will make Pennsylvania the battleground, instead of Virginia, that they will conquer or die! All say the heaviest battle of the war will be fought in this Valley. We all tremble as we have no news from the outside, being completely cut off. Portions of the Cumberland Valley and Franklin Railroads have been torn up. The bridge at Scotland, just rebuilt, has again been demolished.
