OSR (Old West Horror) #1: Bats in the Belfry

During the Siege of the Alamo, legendary folk heroes Davey Crockett and James Bowie, along with an odd man called Plain ‘Ol Joe, are sent to intercept supplies en route to Santa Anna’s troops. After a gun battle, the Texans learn of a mysterious valley nearby where Mexican soldiers were massacred and where there might be large guns they can reclaim.
