How ironic, just yesterday they found 2 250lb bombs in a wooded area here in Stuttgart.
The retired owner of a small week-end cottage near where the bombs were found, who grew up nearby, said the location where they were found was not unknown. They seem to be from an airplane that crashed there during the war. In fact Hr. Wolfgang Oberdorfer still has part of the plane wreckage in use as a fence post

.
Anyway, back to older and larger bombs

.
Didn't at least one "bomb" get detonated under the Vicksburg defenses? I seem to remember a story about some pool African-American who got propelled for some distance through the air by the detonation, but landed to the greatest extent unharmed --on the Union side of the trenches

, although he was dazed and had ringing in his ears for a while. After that he was obliged to tell every passer and all those who sought him out, the story of how he flew over the Vicksburg trenches to freedom

.
Edit:almost forgot
What is called a "fort" in the game represents a number of historic things, and a lot of things that were called "
forts" during the war were not very comparable.
Fort Monroe in Hampton, VA
is in every since of the word what every person understands as a fort. Fort Fisher, on the other hand, looks like a bunch of man-made hills, like a garden landscaper's failed imagination; but it is in all intensive purposes still a fort.
We could debate whether pre-war forts should be eligible to be targeted by LandMine or not. Historically that is how they were used.
Personally, and I've been known to be pretty pedantic, I wouldn't worry about it so much. All that LandMine does is cause a single breach; it doesn't even cause any hits if it were successful.
