Peleliu is an island in the island nation of Palau. Peleliu, along with two small islands to its northeast, forms one of the sixteen states of Palau. The island is notable as the location of the Battle of Peleliu in World War II.
Geography
Peleliu is approximately northeast of the island of Angaur and southwest of the island of Koror. Peleliu has a total area of., its population was about 571, making it the third most populous state of Palau. Most of the island's population lives in the village of Kloulklubed which is the state capital on the northwestern coast. Including the capital, there are a total of four villages:
First sighting of Peleliu, Babeldaob, and Koror recorded by Westerners was by the Spanish expedition of Ruy López de Villalobos at the end of January 1543. They were then charted as Los Arrecifes. In November and December 1710 these three islands were again visited and explored by the Spanish missionary expedition commanded by Sargento MayorFrancisco Padillaon board of the patacheSantísima Trinidad. Two years later they were explored in detail by the expedition of Spanish naval officer Bernardo de Egoy. Following its defeat in the Spanish–American War, Spain sold Palau to Germany in 1899. Control passed to Japan in 1914. During World War II, the Battle of Peleliu was a major battle between units of the United States Marine Corps and United States Army against the Imperial Japanese Army. The battle for the island was particularly brutal because by this time the Japanese military had evolved island defense tactics with strong fortifications in the island's caves and rock formations, which enabled a defense in depth which maximized casualties on the attacking force. On both sides involved in the fighting there were high losses with more than 2,000 Americans and 10,000 Japanese killed, but, remarkably, there were no casualties among the local civilians because they were evacuated from the fighting to other islands of Palau. The ruins of many of the military installations of the era, such as the airstrip, are still intact, and shipwrecks from the battle remain visible underwater just off the coast. There are war memorials on the island to both the American and the Japanese dead. Peleliu and Angaur were the only islands in the Palau archipelago to be occupied by the Americans during the war. The capital of Koror remained in Japanese hands to the end of the war. Peleliu was formally placed under the control of the United States under United Nations auspices in 1947 as part of the Trust Territory of the Pacific Islands. Palau became independent in 1978, and Peleliu was organized as a state within the new republic. In August 2014, Peleliu hosted the "leader's retreat" at the 45th Pacific Islands Forum, featuring representatives from the forum's 15 member states.
Infrastructure
, created by the Japanese in World War II, has the longest and widest runway in Palau, but has been used only by small chartered aircraft after Palau's domestic flights were discontinued in late 2005. A regular boat service connects the island twice a week to Koror and Angaur. Travel time by boat from Koror is over an hour. The small harbor in the far north of the island is shallow and suitable only for yachts with shallow draft.
Peleliu Battlefield
The entire island has been listed on the National Register of Historic Places as the Peleliu Battlefield, and has been designated a U.S. National Historic Landmark.
