Quantrill's Buried Treasure
Stories similar to this seem to abound in the Ozarks (and probably elsewhere as well). For instance, I think I recall hearing about some money taken in a bank or train robbery that Jesse James supposedly buried somewhere. I don't place much stock in most of the lore of buried treasures, but reading or hearing about the stories is still interesting.
By the way, on the morning after Quantrill's band camped in Jasper County, they crossed Shoal Creek at Grand Falls and turned west into Kansas, where they came upon an encampment of Federals stationed at an incomplete fort at Baxter Springs. After being repelled at the fort, they rode out on the prairie and met General James Blunt and his escort coming from Fort Scott. Thinking the guerrillas (many of whom were clad in Federal blue) composed a party sent out to greet him, Blunt was surprised and virtually annihilated at what became known as the Baxter Springs Massacre.
