Before the sun rose, Somers and the regular were in the saddle. The major, whose route lay in a different direction, was no longer their companion. The headquarters of the first army corps were on the Monocacy; and thither the travellers wended their way through a beautiful country, which excited the admiration even of the stoical captain of the regulars, though it was no new scene to him. The reveille was sounding in the camps of the Pennsylvania Reserves as they passed through on their way to the tent of the commanding general. They reached their destination, and their names were sent in by an orderly in attendance. “Captain Somers, I am glad to see you,” said the general, at a later hour, when they obtained an audience. “Thank you, general; I am very grateful for the kindness and consideration you have bestowed upon me,” replied Somers. “You are an aid-de-camp now; but I ought to say that I gave you the appointment because you are a good fellow on a scout.” “I will do my best in whatever position you may place me.” “You were rather unfortunate in your last trip, but you accomplished the work I gave you to do. We shall do some hard fighting in a day or two, and there will be sharp work for you before that comes off.” “I am ready, general. Every man is ready to march or fight as long as he can stand while you are in command.” “I will see you again in an hour, Somers,” said the general, as he turned to Captain Barkwood, who belonged to the engineers, and had been assigned to a position on the staff. Somers soon made the acquaintance of the general’s “military family.” His position and rank were defined in the general orders, and duly promulgated. From those around him he obtained all the current knowledge in regard to the situation of the rebel army, which was posted in the Catoctin valley, with the South Mountain range in the rear, whose gaps and passes it was to defend.
