This is regarding a recent article about a canal dug in Caroline County ["Canal's history remains mystery," Town & County, Nov. 22].
I recall reading about it being dug after Richmond forces attacked the North,
The Northern military wanted to intercept the heavy wagons and equipment of Southern forces on its retreat toward Richmond. I believe the only quality route passed west of Thornburg.
The North had to secretly move heavy cannons by water up the Mattaponi River system beyond where the river became overgrown.
It was decided the canal would best keep secret the Northern trap. It succeeded, and only a few on foot made it south of the trap.
