northwest) and heading back to friendly British lines via the sea were mistaken for Japanese troops and fired upon, with at least major casualties sustained. The building at the entrance of Fort Siloso is now known as the Surrender Chambers and has a vivid portrayal of the scenes of the British and Japanese surrenders in WWII with actual footage of the war being played interactively. This is on the upper storey, with the ground floor having been turned into a souvenir shop. During the Japanese occupation of Singapore from 1942 to 1945, the fort was used as a small prisoner-of-war camp. Post-World War II After the Japanese surrender in 1945, the Royal Navy occupied the fort in 1946 and its guns were manned by the 1st Malay Coast Battery and Royal Artillery. Gurkha detachments from British India took over manning the guns when the British gunners were withdrawn and the 1st Malay Coast Battery was disbanded sometime later in 1946. During the Konfrontasi period between Sukarno's Indonesia and the Malaysian Federation from 1963 to 1965, Fort Siloso was manned by the 10th Gurkha Rifles to prevent Indonesian military-trained saboteurs from landing on Sentosa and Keppel Harbour slightly inland. Fort Siloso became a Catholic retreat for locally based British forces until Sentosa was handed over to the Singapore government following the British military withdrawal starting in 1967. The Singapore Armed Forces (SAF) then took control over the fort. Fort Siloso was then converted into a military museum in 1974, displaying its history and various naval guns. Other coastal guns (both British and Japanese) from different parts of Singapore, such as a pair of Japanese naval cannons discovered and brought over from Mandai, were put here for display. It had previously held the display of the British surrender of Singapore in February 1942 until its relocation to the former Ford Motor Factory (the actual site of the British surrender) in Bukit Timah in February 2006. Plans for the gazetting of Fort Siloso into a national monument began in June 2016 as it is also a wartime museum, and also a military museum dedicated to Republic of Singapore Navy. Fort Siloso was gazetted on 15 February 2022.
