Maybe you are out of the loop but North and South Korea haven't really gotten along very well pretty much since they were split apart after World War II.
Little spat around 1950-1953 perhaps? A British Army regiment local to me lost a lot of men there, and the commanding officer, Lieutenant-Colonel James Carne, was awarded the Victoria Cross for his bravery under fire. He was later captured by the North Koreans and, so it is alleged, subjected to "brainwashing" by them.
"On 22/23 April 1951 near the Imjin River, Korea, Lieutenant Colonel Carne's battalion was heavily and incessantly engaged by vastly superior numbers of the enemy. Throughout this time Colonel Carne moved among the whole battalion under very heavy mortar and machine-gun fire, inspiring the utmost confidence and the will to resist among his troops. On two separate occasions, armed with rifle and grenades, he personally led assault parties which drove back the enemy and saved important situations. His courage, coolness and leadership was felt not only in his own battalion but throughout the whole brigade."
Carne also was awarded the (American) Distinguished Service Cross by the President of the United States for gallant and distinguished services during operations by the United Nations in Korea.
