Someone with a better understanding of steamers will be able to identify which small portion of one this was, LoC, identifed as " Butler's dredge boat ". Miscommunication somewhere.
You know how something will finally make sense? This! Been looking at this LoC image for a lot of years- " Butler's dredge boat sunk Thanksgiving Day 1864 ".
Had no idea what would be a " dredge boat ", why it would sink OR why it was apparently a collection of cracker boxes glued to popsicle sticks. Thought it was some obscure Civil War naval thing and only idiots didn't know about them. Greyhound, a 500 ton steamer, was considered Butler's dispatch boat- may have been one of those " Anyone know what this writing says? " moments in an office somewhere.
WELL it could be the dredge ( dispatch ) boat is what's left of steamer Greyhound. At any rate, for the same general to have lost 2 boats, on or near the same day is awfully unlikely. Transpires it's a terrible story, just nothing to do with dredging anything. Or at least I'm pretty sure? Greyhound was another steamer making the City Point round, no wounded thankfully but horses and generals and mail this run.
