The Aquia railroad gets mentioned several times in the diary. He also gives a good record of the weather they experienced, including some heavy snow. Here is a typical entry from his time at Falmouth and Belle Plain.
Sunday March 8. Got a good comfortable bunk up composed of small poles covered with cedar boughs. It resembles a bed more than that we generaly have. Our camp is said to be about three mile from Bell plains landing, and about five from the old camp. The railroad is within sight, so allso is the Potomac river. We are not as much in the woods as we expected to be.
Monday March 9. The weather to day has been beautifull indeed, resembling a May day. The view from the top of the hills wich surround our camp is grand indeed. The sparkling surface of the Potomac river in the distanced; the neighboring hills covered with camps; a train of cars just crossing the bridge, 75 feet high, and a regiment of cavalry on drill in the valley beneath, is a subject for a painter.Tuesday March 10. Was very disagreeable raining nearly all day, wich turned to snow in the evening. Weesner and Marsh were on detail, Mr. Thorn was sick so I have to cary all the wood we used during the day no inconsiderable job.
This regiment was one of the group that got sent to New York to stop the draft riots. Along the way, the rode a number of trains. That section is worth reading if you are interested in railroad operations behind the front line.
