Ulithi
Ulithi is an atoll in the Caroline Islands of the western Pacific Ocean, about east of Yap, within Yap State.
Name
The name of the island goes back to Proto-Chuukic *úlú-diwo.Overview
Ulithi consists of 40 islets totaling, surrounding a lagoon about long and up to wide—at one of the largest in the world. It is administered by the state of Yap in the Federated States of Micronesia. Ulithi's population was 773 in 2000. There are four inhabited islands on Ulithi Atoll. They are Falalop, Asor ', Mogmog ', and Fedarai '. Falalop is the most accessible with Ulithi Airport, a small resort hotel, store and one of three public high schools in Yap state. Mogmog is the seat of the high chief of Ulithi Atoll though each island has its own chief. Other important islands are Losiap, Sorlen ', and Potangeras .The atoll is in the westernmost of the Caroline Islands, southwest of Guam, east of the Philippines and south of Tokyo. It is a typical volcanic atoll, with a coral reef, white sand beaches and palm trees. Ulithi's forty small islands barely rise above the sea, with the largest being only in area. However the reef runs roughly north and south, by across, enclosing a vast anchorage with an average depth of.
History
The Portuguese navigator Diogo da Rocha is credited as the first European to find Ulithi in 1525. The Spanish navigator Álvaro de Saavedra arrived on the ship Florida on 1 January 1528, claiming the islands for KingPhilipII under the name Islands of the Kings after his patron and the Three Wise Men honored in the approaching Catholic feast of Epiphany. It was later charted by other Spaniards as the Chickpea Islands. It was also visited by the Spanish expedition of Ruy López de Villalobos on 26 January 1543.It remained isolated until visited and explored in detail by Captain Don Bernardo de Egoy in 1712, and later visited by Spanish Jesuit missionaries led by Juan Antonio Cantova together with a group of 12 Spanish soldiers in 1731.
In 1885, Jesuit missionaries encouraged Germany to extend "protection" over the Carolina Islands to protect their profitable trade. However, the Spanish made similar claims and later that year Pope Leo XIII decreed Spain as the ruling power over the islands, granting Germany and the United Kingdom trading rights.
In 1889, a significant earthquake hit Yap, leading the residents to believe that their engagement with outsiders had angered their traditional spirits.
Germany purchased the islands from Spain in 1899 for $4,500,000, conscripting residents as laborers and soldiers. By the early 1900s, Germany had established a police force, post offices, and hospitals on Yap.
During this time, German Capuchin friars began to replace the Jesuits. The friars struggled to convert the citizens to Catholicism. According to a history of the Catholic Church in Micronesia:
Yap had been known as "the child of sorrow" of the Caroline mission right from the start. The people were very slow to accept the new faith and slower still to practice it, the missionaries remarked again and again. There were none of the mass conversions there that had occurred in Pohnpei and other parts of the mission. Converts were made laboriously one by one, with baptisms rarely exceeding 20 or 30 a year throughout the German period. Even those who did receive baptism were all too susceptible to the pagan influences of the social environment, the missionaries thought. The number receiving the sacraments was quite small, even for the modest-sized congregations that the priests had. A pastor would report for a typical year perhaps a single Christian marriage, one or two Christian burials and a few anointing.
Good Friday Typhoon
The "Good Friday Typhoon" hit the atoll in 1907, which killed 473 throughout the Caroline Islands. SMS Planet was dispatched by the Germans to Ulithi for emergency food and relief, and eventually evacuated 114 residents to Yap. German authorities were caught unaware of how to respond to the disaster, and received much criticism for handling of the evacuation.Japanese administration
The atoll was peacefully occupied in 1914 by Japan at the outset of the First World War. Japan was given a mandate to oversee the territory in 1920 by the League of Nations. Under the Japanese occupation, businessmen and soldiers eroded the traditional political system in Ulithi, with the authority of local chiefs ignored. This began a steady decline in the customs and individual culture of the people of Ulithi. The presence of the Catholic church was reinforced by the Japanese, who allowed the continued efforts of conversion to go on, further eroding the indigenous culture. By 1941, 2,000 residents had been converted to Christianity.World War II
Early in the Second World War, the Japanese had established a radio and weather station on Ulithi and had occasionally used the lagoon as an anchorage, but had abandoned it by 1944. As the operations of the United States Navy moved west across the Pacific, the USN required a more forward base for its operations.Ulithi was ideally positioned to act as a staging area for the USN's western Pacific operations. The anchorage was large and well situated for a base, but there were no port facilities to repair ships or resupply the fleet. The US Navy built the very large Naval Base Ulithi that operated in 1944 and 1945.
On 23 September 1944, a regiment of the United States Army's 81st Division landed unopposed, followed a few days later by a battalion of Seabees. The survey ship examined the lagoon and reported it capable of holding 700 vessels—a capacity greater than either Majuro or Pearl Harbor.
On 1 October 1944, the minesweeper USS YMS-385 was sunk by a mine while clearing Zowariau Channel.
Native Relocation
The United States Navy transferred the local islanders to the island of Fedarai for the duration of the hostilities.Occupation
On 4 October 1944 the vessels of Service Squadron 10 began leaving Eniwetok for Ulithi; Service Squadron 10 was termed by Admiral Nimitz as his "secret weapon". Its commanding officer, Commodore Worrall R. Carter, devised the mobile service force that made it possible for the Navy to convert Ulithi to the secret distant Pacific base used during the major naval operations undertaken late in the war, including Leyte Gulf and the invasion of Okinawa. Service Squadron 10 converted the lagoon into a serviceable naval station, creating repair facilities and re-supply facilities thousands of miles away from an actual naval port. Pontoon piers of a new design were built at Ulithi, each consisting of the 4-by-12-pontoon sections, filled with sand and gravel, and then sunk. The pontoons were anchored in place by guy ropes to deadmen on shore, and by iron rods driven into the coral. Connecting tie pieces ran across the tops of the pontoons to hold them together into a pier. Despite extremely heavy weather on several occasions these pontoon piers stood up remarkably well. They gave extensive service, with little requirement for repairs. Piers of this type were also installed by the 51st Battalion to be used as aviation-gasoline mooring piers near the main airfield on Falalop.Within a month of the occupation of Ulithi, a complete floating base was in operation. Six thousand ship fitters, artificers, welders, carpenters and electricians arrived aboard repair ships, destroyer tenders, and floating dry docks. had an air-conditioned optical shop and a metal fabrication shop with a supply of base metals from which she could make any alloy to form any part needed., which looked like a big tanker, distilled fresh water and baked bread and pies. The ice cream barge made a shift. The dry docks towed to Ulithi were large enough to lift dry a 45,000-ton battleship.
Fleet oilers sortied from Ulithi to meet the task forces at sea, refueling the warships a short distance from their combat operational areas. The result was something never seen before: a vast floating service station enabling the entire Pacific fleet to operate indefinitely at unprecedented distances from its mainland bases. Ulithi was as far away from the US naval base at San Francisco as San Francisco was from London, England. The Japanese had expected that the vastness of the Pacific Ocean would make it very difficult for the US to sustain operations in the western Pacific. With the Ulithi naval base to refit, repair and resupply, many ships were able to deploy and operate in the western Pacific for a year or more without returning to the naval base at Pearl Harbor.
The Japanese had built an airstrip on Falalop. It was expanded and resurfaced, the runway running the full width of the island. The east end of the strip was extended approximately past the natural shoreline. During the operations, 4,500 sacks of mail, of air freight and 1,200 passengers would use this airstrip. A number of small strips for light aircraft were built on several of the smaller islands. The Seabees completed a fleet recreation center at Mog Mog island that could accommodate 8,000 men and 1,000 officers daily. A 1,200-seat theater, including an stage with a Quonset hut roof, was completed in 20 days. At the same time, a 500-seat chapel was built. A number of the larger islands were used both as bases to support naval vessels and facilities within the lagoon.
The Japanese still held Yap. Early after the US occupation they mounted a number of attacks but caused no damage to the Seabees working on the islands.
On 20 November 1944 the Ulithi harbor was attacked by Japanese kaiten manned torpedoes launched from two nearby submarines. The destroyer rammed one in the early morning hours. At 5:47 the fleet oiler, at anchor in the harbor, was struck and sunk. Destroyers began dropping depth charges throughout the anchorage. After the war Japanese naval officers said that two tender submarines, each carrying four manned torpedoes, had been sent to attack the fleet at Ulithi. Three of the kaiten were unable to launch due to mechanical problems and another ran aground on the reef. Two did make it into the lagoon, one of which sank USS Mississinewa. A second kaiten attack in January 1945 was foiled when I-48 was sunk by the destroyer escort. None of the 122 men aboard the Japanese submarine survived.
On 11 March 1945, in a mission known as Operation Tan No. 2, several long range aircraft flying from southern Japan attempted a nighttime kamikaze attack on the naval base. One struck the , which had left a cargo light on despite the blackout. The plane struck over the stern starboard quarter, damaging the flight deck and killing a number of crewmen. Another crashed on Sorlen Island, having perhaps mistaken a signal tower there for the superstructure of an aircraft carrier.
By 13 March there were 647 ships at anchor at Ulithi, and with the arrival of amphibious forces staging for the invasion of Okinawa the number of ships at anchor peaked at 722.
In late June 1945, the Japanese aircraft-launching super submarines I-400 and I-401 were diverted from their planned attack on the Panama Canal to attack Ulithi Atoll. However, their mission was interrupted by the destruction of Nagasaki and Hiroshima, followed by the Japanese surrender.
After the Leyte Gulf was secured, the Pacific Fleet moved its forward staging area to Leyte, and Ulithi was all but abandoned. In the end, few US civilians ever heard of Ulithi. By the time naval security cleared release of the name, there were no longer reasons to print stories about it. The war had moved on, but for seven months in late 1944 and early 1945, the large lagoon of the Ulithi atoll was the largest and most active anchorage in the world.
