During the Gettysburg campaign, many soldiers commented on the fine stone aqueduct they observed while crossing the Monocacy. I wonder if it still stands. Here are a few pertinent comments:
- June 29 [1863] Left Buckeysville [Buckeystown?] at 6 a.m., crossed Monocacy on a stone bridge that was built 45 years ago [that would be 1818]. (Diary of Andrew H. Boyd, 108th New York)
- June 27, noon Forded Monocacy within sight of its junction with the Potomac, the water was waist deep, with the added danger of a strong current that took quite a number of the men off their feet, even threatening to sweep some into the Potomac. March continued during the afternoon for some miles along the right (west) bank of the Monocacy, then leaving the river the brigade moved through Buckeystown. (Memoir of Thomas H. Mann, 18th Massachusetts)
- June 27 Monocacy River about 200 feet wide, water waist deep, bivouacked for night near the Monocacy bridge three miles from Frederick City. (Ziba Graham, On to Gettysburg, 16th Michigan)
- June 27 Crossed the Monocacy by the aqueduct, marched up the towpath several miles, then crossed under the canal by means of a culvert. (Letters of Joseph Irwin, 29th Pennsylvania)
- June 25 Monocacy aqueduct is a fine piece of mason work. We passed directly under it. (Journal of Charles Mattocks, 17th Maine)
- June 25 Crossed the River Monocacy on the aqueduct, a stone one. It is the finest work I ever saw. (Diary of Jacob Thomas Zehrung, 73rd Ohio)
