Corregidor is an island located at the entrance of Manila Bay in the southwestern part of Luzon in the Philippines, and is considered part of Cavite City and thus the province of Cavite. It is located 48 kilometres (30 mi) west of Manila, the nation's largest city and one of its most important seaports for centuries since the Spanish colonial period. Due to its strategic location, Corregidor has historically been fortified with coastal artillery batteries to defend the entrance of Manila Bay and Manila itself from attacks by enemy warships.
The Harbor Defenses of Manila and Subic Bays were a United States Army Coast Artillery Corps harbor defense command, part of the Philippine Department of the United States Army from circa 1910 through early World War II.

Fort Mills was the location of US Major General George F. Moore's headquarters for the Philippine Department's Harbor Defenses of Manila and Subic Bays in early World War II, and was the largest seacoast fort in the Philippines. Most of this Coast Artillery Corps fort was built 1904–1910 by the United States Army Corps of Engineers as part of the Taft program of seacoast defense. The fort was named for Brigadier General Samuel Meyers Mills Jr., Chief of Artillery 1905–1906. It was the primary location of the Battle of Corregidor in the Japanese invasion of the Philippines in 1941–42, and of the recapture of Corregidor in February 1945, both in World War II.

Some of the bases dates back to 1898, the end of the Spanish–American War. Starting in 1938 civilian contractors were used to build new facilities in Manila to prepare for World War II. Work stopped on December 23, 1941, when Manila was declared not defendable against the Empire of Japan southward advance, which took over the city on January 2, 1942, after the US declared it an open city. US Navy construction and repair started in March 1945 with the taking of Manila in the costly Battle of Manila ending on March 2, 1945. Naval Base Manila supported the Pacific War and remained a major US Naval Advance Base until its closure in 1971.

The US Naval Bases in Philippines were lost to the Empire of Japan in December 1941 during the Philippines campaign of 1941–1942. In February 1945 the United States Armed Forces retook the Philippines in the Battle of Manila in 1945. Before the captured US bases on Luzon were retaken the US Navy Seabees built a new large base, Leyte-Samar Naval Base, on the Philippine Island of Leyte, starting in October 1944.
