Outpost Harry was a remote Korean War outpost located on a tiny hilltop in what was commonly referred to as the "Iron Triangle" on the Korean Peninsula. This was an area approximately 60 miles (100 km) northeast of Seoul and was the most direct route to the South Korean capital. The soldiers of the Greek Expeditionary Force, Sparta Battalion adapted its name and called it Outpost "Haros", the modern Greek equivalent to Charon, Greek mythology's ferryman to the underworld of Hades.
