Dumb ol' Attila settled a city right between two of my allies, both of which are mercantile CS's. After I issued a DoW, Colombo marched over and conquered it. As is the general case with CS's, it razed the city--and in this case it left behind some nice jewelry lying amidst the ruins. Oddest thing is that Colombo didn't even have jewelry originally. They had porcelain. Anyway, hadn't read of anyone discovering this little exploit yet. Thought it was worth sharing. Give it a try!
