ground and only the gobernadorcillo (mayor) of Biliran town escaped capture by the raiders. The settlements of Biliran, Caybiran, Mapuyo and Maripipi were also destroyed by the Moros. The Moros staged their attack by marching inland along a river named Anas for a distance of 1.5-2 leguas (leagues). Having covered part of the interior around a mountain, they managed to capture the inhabitants, with the exception of the gobernadorcillo who escaped. The houses and property of the natives were burned or destroyed. The church building suffered the same fate and its valuables were taken away by the raiders. Post-Moro invasion When the Moro raiders were neutralized in the early 19th century, the local inhabitants went into the business of organizing new towns (then called "pueblos") in the present geography of Biliran Province. In 1828, Caibiran on the east became an independent municipality and parish, the second to be created in Biliran Island. Naval became the third town, carved out of the territory of Biliran town. It first became a separate parish in 1860. The Spanish colonial government officially recognized its municipality status on September 23, 1869, following the petition submitted around 1861. Almeria became a separate town in 1886 and was named after the City of Almería in Spain. Maripipi used to be a barrio of Naval. It was officially inaugurated as a town in 1867, two years ahead of its mother town, then folded up and was reduced into a barrio of Almeria, and then became a town again in 1899. Maripipi and the new towns of San Clemente (later Kawayan), Culaba and Esperanza (later Cabucgayan) were created around 1899 by the revolutionary government under Pres. Emilio Aguinaldo. World War II During the World War II, Biliran had its own guerrilla forces under the Leyte command of Colonel Ruperto Kangleon. The guerrilla operation was of invaluable assistance to the successful landing of the American liberation forces at Palo, Leyte, on October 20, 1944, just before the Battle of Leyte Gulf. In 1945, Biliran was liberated by the Philippine Commonwealth forces of the 9th Infantry Division of the Philippine Commonwealth Army who landed in Biliran. Aided by the local guerrilla forces, they attacked the Japanese troops on the island during the Battle of Biliran during World War II. Provincehood On April 8, 1959, Republic Act No. 2141 was signed into law effectively making Biliran a sub-province of Leyte. The island
