Corregidor, fortified island situated 3.2 km. (2 mi.) off the
Bataan peninsula, part of the Philippines island of Luzon. After elements of
Lt-General Homma's Fourteenth Army had landed on Luzon in December 1941 (see
Philippines campaigns), and had established themselves there, the US Army commander,
Lt-General MacArthur, declared Manila an open city, ordered his army to withdraw into the Bataan peninsula, and then withdrew his HQ to Corregidor. On 11 March he handed over command to
Lt-General Wainwright and left for Australia.
Corregidor, only 5.6 km. (3.5 mi.) long and 2.4 km. (1.5 mi.) wide, was the Gibraltar of the east. It was stocked to feed 10,000 men for a six-month siege, was heavily fortified, and had an intricate tunnel system which protected vulnerable elements such as the hospital from air attack. Along with three other, smaller, fortified islands nearby, its position in Manila Bay denied to the Japanese the use of the finest harbour in the Orient.
Heavy Japanese air raids and artillery fire damaged Corregidor's surface installations, but caused no critical damage or excessive casualties. But after Bataan fell, on 9 April 1942, Japanese artillery massed there, and almost constant air raids destroyed beach defences and all but three of the guns. So intense was the bombardment that the island's topography was altered: cliffs collapsed, woods were obliterated, and the shore road was blown into the sea. The island lay ‘scorched, gaunt, and leafless’, when men of Homma's 4th Division landed there on the night of 5 May. In fact the assault miscarried and only about 800 men out of 2,000 reached the shore, but these established a beachhead, tanks and artillery were landed, and the 11,000-strong garrison suffered heavy casualties. By morning the Japanese were almost into the tunnel system, which held 1,000 wounded, and Wainwright surrendered.
