Battle off Samar in the context of "San Bernardino Strait"

Samar (/ˈsɑːmɑːr/ SAH-mar) is the third largest island in the Philippines, with a total population of 1,924,651 as of the 2024 census. It is located in the eastern Visayas and its main language and ethnicity is Waray while its main religion is Roman Catholic. Since 1965, the island is divided into three provinces: Western Samar, Northern Samar, and Eastern Samar. The capitals of these provinces are, respectively, Catarman, Catbalogan, and Borongan., all part of the Eastern Visayas region. In commemoration of the establishment of these provinces, June 19 is celebrated as an annual holiday. The island was first sighted by Ferdinand Magellan on March 16, 1521. Although he did not land, other expeditions were made. Many names, such as Samal, Ibabao, and Tandaya, were given to the island prior to the arrival of the Spaniards in 1596. During the early days of Spanish occupation, Samar was under the jurisdiction of Cebu. In the Philippine–American War, Eugenio Daza led a successful attack against the United States Army, later called the Balangiga massacre. This attack led to the Pacification of Samar and deaths of 2,000 people.

In the American colonization of the Philippines, two uprisings were created; the former was the Pulajan movement which caused massacres in the country. The Battle off Samar was held off the island. In the martial law under Ferdinand Marcos, the Sag-od massacre was caused. After the martial law, the island still has the New People's Army rebellion. Samar is the easternmost island in the Visayas archipelago. The island lies to the northeast of Leyte and lies to the southeast of the Bicol Peninsula on Luzon. To the west is the Samar Sea, and to the north and east of Samar lies the Philippine Sea. The island has the Samar Island Natural Park and has numerous biological discoveries and forests.

USS Johnston (DD-557) was a Fletcher-class destroyer built for the United States Navy during World War II. She was named after Lieutenant John V. Johnston, an officer of the US Navy during the American Civil War. Johnston was laid down in May 1942 and was launched on 25 March 1943. She entered active duty on 27 October 1943 under the command of Lieutenant Commander Ernest E. Evans and was assigned to the US Pacific Fleet. Johnston provided naval gunfire support for American ground forces during the Gilbert and Marshall Islands campaign in January and February 1944 and again, after three months of patrol and escort duty in the Solomon Islands, during the recapture of Guam in July. Thereafter, Johnston was tasked with escorting escort carriers during the Mariana and Palau Islands campaign and the liberation of the Philippines.

On 25 October 1944, while assigned as part of the escort to six escort carriers, Johnston, two other Fletcher-class destroyers, and four destroyer escorts were engaged by a large Imperial Japanese Navy flotilla. In what became known as the Battle off Samar, Johnston and the other escort ships charged the Japanese ships to protect nearby US carriers and transport craft. After engaging several Japanese capital ships and a destroyer squadron, Johnston was sunk with 187 dead, including Evans. Johnston's wreck was discovered on 30 October 2019 but was not properly identified until March 2021. Lying more than 20,000 feet (6,100 m) below the surface of the ocean, it was the deepest shipwreck ever surveyed until the 22 June 2022 discovery of USS Samuel B. Roberts, sunk during the same engagement.
