“Sadly lacking as was information on the objective area,” commented the Division G-2 report, “more so was that on the enemy in the area.” Early in September, however, the Attack Force and Landing Force concurred in the initial X Corps estimate of 1,500 to 2,500 NKPA troops in the immediate area, consisting largely of newly raised personnel.[94] [94] See Appendix I for the Order of Battle of the units which opposed the 1st Marine Division throughout the Inchon-Seoul operation, listing them in chronological order as to area of employment, strength, and effectiveness. Radio reports of first-hand observations in the objective area, though coming too late for initial planning purposes, confirmed some of the G-2 estimates. This dangerous mission was undertaken by Lieutenant Eugene F. Clark, a naval officer on General MacArthur’s JSPOG staff. U. S. and British Marines provided an escort on 1 September when the British destroyer _Charity_ brought him from Sasebo to a point along the coast where the South Korean patrol vessel PC 703 waited to land him at Yonghung-do, an island about 15 miles southwest of Inchon.[95] [95] This account is based upon: Capt James B. Soper interv, 16 Aug 54; and Karig, _Korea_, 176–191. Clark went ashore with a small arsenal of firearms, grenades and ammunition, as well as 30 cases of C rations and 200 pounds of rice. He quickly made allies of the 400 friendly Korean inhabitants of the island and organized his own private little “army” of about 150 youths from 14 to 18 years old. These “troops” were posted about Yonghung-do for security, since the near-by island, Taebu-do, was occupied by 400 NKPA soldiers within wading distance at low tide. The naval officer had no illusions as to what his fate might be in the event of capture. Day and night, he kept a grenade within reach, since he did not intend to be taken alive. When the long expected enemy attack from Taebu-do materialized, he commandeered a “one-lung” South Korean motor sampan and fought it out with the NKPA motor sampan escorting boats filled with soldiers. The enemy began the strange “naval” battle with a few badly aimed rounds from a 37mm tank gun. Clark and his crew of three friendly Koreans finished it with a long burst from a .50 caliber machine gun. After sinking the NKPA motor sampan, he destroyed another boat with 18 soldiers aboard and captured three prisoners for questioning. One night the intrepid lieutenant rowed a dinghy to the Inchon sea wall. When the tide went out, he tested the mire by wading in it up to his waist. This experience led to the sending of a radio report, “Inchon not suitable for landing either troops or vehicles across the mud.”
