The 1996 Gangneung submarine infiltration incident
On September 15, a North Korean Sang-O class submarine landed a three person special operations reconnaissance team on the shores near Gangneung. Their mission was to spy on the naval installations in the area and then return. The submarine, however, ran aground . The crew then decided to destroy the sensitive equipment in the submarine and try to make it to the DMZ. The crew split up in several groups but one was soon spotted by a civilian who became suspicious and alerted the authorities, who quickly mobilized 40,000 soldiers. A 49-day long manhunt ensued, from 18 September through 5 November, resulting in the capture or elimination of all the crew and members of the reconnaissance team, except one, who is believed to have made it back to North Korea. 16 South Korean soldiers and civilians died and 27 were wounded. Of the 26 North Korean infiltrators, 1 was captured, 11 were murdered by the other members or died from a murder-suicide, 13 were killed in firefights with the ROK Army, and 1 reportedly escaped back to North Korea. wikipedia
