                MINESWEEPING IN WONSAN HARBOR, 1950--1952By 
                  Burl E.  Gilliland, CAPT, USNR Retired
 This represents one account of many 
                  incidents I experienced while serving aboard the minesweeper, 
                  USS HERON (AMS-18), during the Korean War. I recall it happening 
                  some time during 1951. I was an officer with the rank of Ensign. 
                  The ship had a complement of 4 officers and 28 enlisted men. 
                  We operated in waters all around the Korean peninsula, from 
                  the Hungnam and Chongjin area on the Northeast Korean coast 
                  (facing the Sea of Japan) to Inchon on the Northwest Korean 
                  coast (facing the Yellow Sea). The lion's share of our work 
                  occurred in the vast outer and inner Wonsan harbor and greater 
                  Bay of the entire Wonsan-Hungnam area.
 The incident reported here 
                  happened just about sunset on the lee side of a very small island 
                  inside the Wonsan harbor. I believe we called the island, Rei 
                  To (pronounced rye tow). Rei To was routinely occupied  |  
                Taken about 1 second after the mine was exploded with 50 cal fire.

                and used by the U. S. Marines as an observation point and a 
                  spotter location for interdiction fire in support of U. S. surface 
                  warfare ships and for fighter-bomber raids from the U. S. Air 
                  Force and aircraft from U. S. aircraft carriers. Those carriers 
                  operated just off the coast, out of sight from land, within 
                  minutes of access to the battle areas and rail and transportation 
                  hubs that supplied the North Korean military forces.  The wartime routine of the minesweeping fleet involved sweeping 
                  the entire harbor area during daylight hours and pulling patrol 
                  duty during nights to prevent the North  |  
           
            | Koreans from re-mining the sea 
                lanes and to help U.S. forces maintain the maritime naval blockade 
                of the peninsula. The three ships that comprised my particular 
                division were the USS HERON (AMS-18), and two sister ships, USS 
                FIRECREST (AMS-10), and USS WAXBILL (AMS-39). Several other divisions 
                of the minesweeping fleet included a large assortment of AMS's, 
                AMs, and even a few DMSs (Destroyer/minesweepers).

                This mine was right under our nose. Korea 1951 | We were at our battle stations 
                most of the time. Needless to say, we were a constantly weary 
                bunch. Because of the persistent danger of unswept mines exploding 
                underneath the vessel, the crew could not stay underneath any 
                overhead. (The reason for this rule was that whenever a mine explodes 
                underneath a vessel, everyone standing beneath an overhead would 
                usually die as a result of a broken neck). So, day after day, 
                in all sorts of weather, the whole crew, except for two galley 
                personnel, was required to be out in the open during minesweeping 
                operations. Our meals consisted mainly of soup and sandwiches 
                and/or chili and crackers, brought to us on the open decks outside. 
                We would eat that fare while wearing our life jackets and battle 
                gear, including keeping our steel battle helmets on at all times. |  
           
            | That brings us to the value 
                of our getting an occasional respite, from minesweeping and/or 
                patrol duties, by anchoring in the lee of an island like Rei To 
                in order to rest and enjoy a relaxing dinner meal inside in our 
                regular messing facilities. On one such occasion, we were unaware 
                that during that very day, while we were out sweeping, the North 
                Koreans recaptured Rei To and sent the U. S. Marines scurrying. 
                Unfortunately for us, nobody communicated to us that the island 
                was now in hostile hands. So there we were, four or five AMSs, 
                anchored, like sitting ducks, some 3000 yards from an enemy held 
                island. With our main engines shut down, we were just settling 
                down to eat our evening meal when the enemy opened fire with some 
                sort of small guns. I would guess that they were firing something 
                like 50 caliber machine guns, plus one or two weapons similar 
                to our 20-mm guns. |

                A mine exploding in the bay at Wonsan. USS Firecrest AMS 10 bagged 
                this potent baby at about 250 yards. A charge of about 1000 lbs 
                of TNT . . . the column of water rose to about 300'. | As the bullets whizzed through our rigging and splashed all about 
                us, we simultaneously received assistance from U. S. warships 
                that were close by. All of our minesweepers sounded general quarters, 
                rapidly started main engines, and slipped anchors. (Released our 
                anchors and got underway without them. I suppose those anchors 
                are still embedded in the muddy bottom of Wonsan Harbor today). The primary relief that caused the enemy to cease fire came from 
                the cruiser, USS MANCHESTER. That ship had observed the enemy 
                shelling us. And she was steaming at flank speed toward Rei To 
                and firing her six forward main batteries into the enemy's gun 
                positions. That meant that  |  
          continued to pound the enemy location using napalm and other impressive 
        ordinance. 
            | the MANCHESTER was also firing 
                continuously directly over our ship. I remember, as I was stood 
                on the main deck, the terrific impact of the concussions from 
                MANCHESTER's main batteries whose shells were barely skimming 
                over our ship's super structure. For a short while the enemy's 
                shore batteries started firing at the MANCHESTER instead of at 
                us. That took the heat off us. But the cruiser effectively silenced 
                the enemy's shore batteries before the U.S. Navy jet fighters 
                arrived and  |

                The whole experience lasted only a 
                  few moments, but I remember it well. In seagoing lingo, We 
                  got the hell out of there. And, to the best of my recollection, 
                  that was the very last time we anchored in the lee of Rei To. 
                  And I don't think any of us ever got an opportunity to thank 
                  the people on the USS MANCHESTER, which just happened to be 
                  conveniently on station in our vicinity that evening.   |  Mines
