Query: American post in N. Korea

[Michael Ballard <mballard@hitter.net>]

Fellow list members:

Last November we had a Korean War veteran visit my classroom to
celebrate the meaning of Veteran's day.  He served on a minesweeper
during the war.

In his presentation he mentioned that an American outpost was held
during the war in the northeast section of North Korea.  He didn't know
a lot about it, having visited there only once with his minesweeper, and
tangling with some enemy shore defenses there.

I have read about the Korean War and try to cover it adequately in
class, but I have never heard of this before, nor can I find a reference
to it in the few general histories of the War that I have.  

Do any of those on the list know whereof I speak?  It's an area I'd like
to explore and share with my students.

Many thanks
