Oh, and i would guess that humanity would have ended as well, seeing as they werent all that smart back in the day, they would've probably tried to burn the bombs in order to destroy them, setting them off causing them all to go kabloowie.
Just an FYI, you can't set off a nuclear warhead by burning it. The chain reaction which causes the big boom is caused by accelerating a neutron into a fissionable mass. Yes, in primitive bombs, they did this with a primer (much like how a bullet works), but on modern nuclear technology, it's done electromagnetically. And regardless of the iteration of the technology, there was a safety in place until the warhead or bomb was 'armed' that would prevent anything from happening until it was specifically triggered. If there was a silo in your backyard, you're much more in danger from leaking radition (that shit doesn't stop, so I hope you have lead underpants) than you would be from an accidental explosion.
Think about it: if there was going to be an accidental nuclear explosion, don't you think that, at least once in all these years, it would've happened by now, particularly given the group idiocy of some of the governments that possess these things?
As to a delivery system, the OP implied that the Bomb was developed by the people in the Middle Ages, so I've got to think that someone who could invent that could also create a simple mechanical device like a
FUCKING EGG TIMER! You hide your bomb in a very sturdy hay wagon, drive it into the target city, park the thing and hope your horse is fast enough to prevent you from ending up as an alternative light source.
Well, that was an amusing way to waste 20 minutes...
