July 5th. Left camp very early this morning. A heavy downpour of rain. Passed through Georgetown, on through Washington. The mud in Pennsylvania Avenue was ankle deep. Marching very hard and disagreeable, so much so that we were obliged to take off our leggins and throw them away. Our first time in Washington. Boarded a train at the B. & O. R. R. station, going north. Nothing important taken place. At the Relay House, near Baltimore, train switched to the west bound track. After a long tedious ride we reached the Monocacy Junction, thence to Frederick City, where we left the train and began a march out on the South Mountain Road, passing New York’s crack regiment, the 7th, on picket duty. Stopped at the top of South Mountain.
