In 1917, the Naval Base at Guantanamo Bay held the largest rifle range in the western hemisphere.  In the late 1920’s, the enlisted mess hall that supported the range burned and collapsed, crushing the normally durable heavy porcelain dishes from which Marines ate their meals and drank their coffee.  In the course of preparing the site for a replacement mess hall, the charred wreckage was removed and dumped over a cliff near what came to be known as Glass Beach.

The fiery destruction of the mess hall and its dishes explains why no intact versions of early twentieth-century Marine Corps porcelain mugs are known to exist.
