My grandfather, then-Captain James HW Treadwell, was the senior US adviser to the South Korean Army in the Sunchon Province when Kim Il-Sung (the current crackpot's father) and a bunch of his cronies staged the Sunchon-Yosu Revolt. The South Korean 14th Regiment, composed almost entirely of North Koreans and communist South Koreans, was the primary enemy force in this conflict, which resulted in much of the city of Yosu being destroyed and hundreds of civilians killed (mostly murdered by the communists for having anything remotely to do with the government). My grandfather helped rally and organize the other two ROK regiments in the province in putting down the rebellion, but some commie sympathizers in one of these regiments allowed Kim Il-Sung to slip out of the city when it became obvious that the revolt was doomed to failure. He caught a sampan north and began plotting his even more ambitious plan to send forces across the 38th Parallel.
As a side-note, the ROK Army made an interesting decision in how to remove the stain of dishonor brought upon it by the 14th Regiment. To this day, the ROK Army does not use the number four in any of its unit designations. The Air Force and Navy do, but the Army has not forgotten Sunchon-Yosu.
I seem to recall that in the language, the word for the number "four" sounds similar to the word for "death", and that it is common business practice (a.k.a. superstition) to avoid it, much the way that tall American buildings used to skip the 13th floor. I'm fairly sure that's true in at least one other Oriental language, but the details escape me at the moment.
