The Tanga Skirmish Campaigns book does have "The Battle of the Bees" as one of the scenarios (complete with rules for them). A different one to the one being played here, I think, though.
The bees scattered everybody, not just the Indians. There were some (silly) suggestions that it had been a dastardly Hun trick in the aftermath of the disastrous battle, which is probably why nobody remembers that the Germans ran from them too.
