What are the major Greyhawk battles? Has anyone reenacted them?
Emery(sp?) Meadows was the original temple of elemental evil battle, and the reign of fire wasn’t so much a battle as a apocalypse. What others are there? Wasn’t there a Greyhawk City one?
Well, the obvious were the Greyhawk wars. And shortly before them, Gary had the armies of Tenser chase Robilar all over the place, eventually taking over Robilars castle outside of Greyhawk city.
Also, are you looking for specific battles or wars? There's the Short War, also called the Little War, where Imperial Keoland moved against Veluna, who as aided by Furyondy.
there was the Battle of the Opicm River (I think that's how it's spelled), where Iuz and the Horned Society joined forces to whomp the Rovers of the Barrens...
and it really depends on if you're talking before or after the Wars....
I was going to mention Osson's Ride (wee, I just did), but I forgot where it was originally mentioned so I can't give any detail.
Edit for More Detail: It was a sucidal raid into the Great Kingdom and its domain by Almorian forces under command of the titilar Osson to draw the GK forces away from Almor. You can read more about it here (especially the last three posts.
