I am a writer in Washington DC and regularly bike sections of the towpath from Georgetown to White's Ferry and beyond. I am dismayed at how little signage on the Civil War history of the canal there is in those sections. I imagine it's just as bad farther north too. But I've been giving talks and have an article pending about what happened in 1863 between Great Falls, to the south, and Lock 24 or Seneca Creek to the north. There is signage but it's both wrong and in the wrong place. Anyway, I did a presentation for the Montgomery County History Society in April 2020 and put it online. Anyone riding that section might want to watch it. Not only was the towpath constantly patrolled by Union cavalry, but also on the night of June 27, 1863, 5,000 Confederate cavalry rode where you are riding.
