Operation Hailstone was a massive naval attack launched on 17 February and 18 February , 1944 , during World War II against the Japanese naval and air base on Truk in the Caroline Islands , a pre-war Japanese territory. Truk was Japan's main base in the South Pacific as well as the operating "home" base for the Imperial Japanese Navy 's Combined Fleet. The Atoll was the only major Japanese airbase within range of the Marshall Islands and was a significant source of support for Japanese garrisons located on islands and atolls throughout the central and south Pacific. BACKGROUND To ensure air and naval superiority for the upcoming Invasion Of Eniwetok Admiral Raymond Spruance ordered an attack on Truk. Vice Admiral Marc A. Mitscher 's Task Force 58 had five fleet Carriers ( ''Enterprise'' , ''Yorktown'' , ''Essex'' , ''Intrepid'' , and ''Bunker Hill'' ) and four light carriers ( ''Belleau Wood'' , ''Cabot'' , ''Monterey'' , and ''Cowpens'' ), embarking more than 500 planes. Supporting the carriers was a large fleet of seven Battleship s, and numerous Cruiser s, Destroyer s, Submarine s, and other support ships. (Morison, 1961) Fearing that the base was becoming too vulnerable, the Japanese had relocated the aircraft carriers, battleships, and Heavy Cruiser s of the Combined Fleet to Palau a week earlier. However, numerous smaller warships and merchant ships remained in and around the anchorage. ATTACK The U.S. attack involved a combination of airstrikes, surface ship actions, and submarine attacks over two days and appeared to take the Japanese completely by surprise. Several daylight, along with a nighttime, airstrikes employed fighters, dive bombers, and torpedo aircraft in attacks on Japanese airfields, aircraft, shore installations, and ships in and around the Truk anchorage. A force of U.S. surface ships and submarines guarded possible exit routes from the island's anchorage to attack any Japanese ships that tried to escape from the airstrikes. In total the attack sank three Japanese Light Cruiser s ( ''Agano'' , ''Katori'' , and ''Naka'' ), six destroyers ( ''Oite'' , ''Fumizuki'' , ''Maikaze'' , ''Hagio'' , ''Isogu'' , and ''Tachikaze'' ), three other warships, and 32 merchant ships. Some of the ships were destroyed in the anchorage and some in the area surrounding Truk lagoon. Many of the merchant ships were loaded with reinforcements and supplies for Japanese garrisons in the central Pacific area. Very few of the troops aboard the sunken ships survived and little of their cargos were recovered. (Lindeman, 2005) ''Maikaze'', along with several support ships, was sunk by U.S. surface ships while trying to escape from the Truk anchorage. The survivors of the sunken Japanese ships reportedly refused rescue efforts by the U.S. ships. (Morison, 1961) ''Agano'', which was already en-route to Japan when the attack began, was sunk by a U.S. submarine, the '' Skate ''. ''Oite'' rescued survivors from the ''Agano'' and returned to Truk lagoon to assist in its defense with her anti-aircraft guns. She was sunk soon after by air attack with the ''Agano'' survivors still on board, killing all of them and all but 20 of the ''Oite's'' crew. (See ''Agano'' ) Over 250 Japanese aircraft were destroyed, mostly on the ground. Many of the aircraft were in various states of assembly, having just arrived from Japan in disassembled form aboard cargo ships. Very few of the assembled aircraft were able to take off in response to the U.S. attack. Several Japanese aircraft that did take off were claimed destroyed by U.S. fighters or gunners on the U.S. bombers and torpedo planes. The U.S. lost twenty-five aircraft, mainly due to the intense anti-aircraft fire from Truk's defenses. However, many of the aircrews were rescued by amphibious aircraft or submarines. A nighttime Torpedo attack by a Japanese aircraft from either Rabaul or Saipan damaged the ''Intrepid'' and killed 11 of her crew, forcing her to return to Pearl Harbor and later, San Francisco for repairs. She returned to duty in June, 1944. Another Japanese air attack slightly damaged the battleship '' Iowa '' with a bomb hit. (Morison, 1961) AFTERMATH The attacks for the most part ended Truk as a major threat to Allied operations in the central Pacific. Thus, the Japanese garrison on Eniwetok was denied any realistic hope of reinforcement and support during the invasion that began on February 18, 1944, greatly assisting U.S. forces in their conquest of that island. The Japanese later relocated about 100 of their remaining aircraft from Rabaul to Truk. But, these aircraft were attacked by U.S. carrier forces in another attack on 29 and 30 April, 1944, destroying most of them. The April, 1944 strikes found no shipping in Truk's lagoon and were the last major attacks on Truk during the war. Truk was isolated by Allied (primarily U.S.) forces as they continued their advance towards Japan by invading other Pacific islands such as Guam, Saipan, Palau, and Iwo Jima. Cut off, the Japanese forces on Truk and other central Pacific islands ran low on food and faced starvation before Japan surrendered in August, 1945.
