June 19.— I had a good sleep last night, and enjoyed it very much. We left our camp at Herndon Station this morning at 8 o’clock, and followed Doubleday’s division, which preceded us yesterday, to Guilford’s Station, some three miles. Our corps was camped on Broad Run. In the afternoon I went out with General Paul to establish the picket line. The road was beautiful, being wooded on both sides, with oak groves. We left a real Union family at Herndon, a family from Pennsylvania. This evening we received orders to move on to Goose Creek, but the orders were countermanded. I was sent to General Doubleday to countermand them. Our signal officers sent up a rocket this evening, to the great alarm of our cook, George, who had never seen anything of the kind before. We had a very heavy shower this evening, which I got caught in, much to my disgust, as it is the only time I have ever been out without my rubber coat.
