Shorpy's pictures today had one of the wreck of the dredge boat being used by General Benjamin Butler to dig the Dutch Gap Canal to bypass Confederate batteries on the James River in 1864.
It was sunk by a Confederate shell on Thanksgiving Day, 1864. I was unable to find out its name.
One thing I like about Shorpy is where you can view the photograph full size, up close and personal. This way you an look for detail.
Across the James River from the wreck, on a bluff, is a Union lookout tower. Plus, you can see monitors in the river, perhaps as many as three, or perhaps two if one of them is a double turret. Two Union soldiers are standing by the wreck near shore on some wooden planks.
