Claver, Surigao del Norte
A large part of the municipal land area is a mining reservation due to extensive mineral deposits.[6] Claver was one of many coastal towns that for some time were ignored after the American and Filipino military forces surrendered to the Japanese in May 1942.Claver became the headquarters of the 114th Infantry Regiment of 10th Military District, which was the guerrilla organization under the jurisdiction of the United States Army.Some residents had fled for fear of a Japanese raid or occupation of the town, but an American whose family took refuge there said Claver still had a feeling of normalcy to it.Very early in the morning several Japanese ships appeared off the coast and began shelling the town with five-inch guns.
