6th Heavy Anti-Aircraft Regiment, Royal Artillery was an air defence unit of the British Army raised in the years leading up to World War II. It served in the Battle of France and was evacuated from Dunkirk. Re-equipped, it defended London and the West Midlands during the Battle of Britain and The Blitz. It was then sent to the Middle East theatre, but was diverted en route to the Far East, where the Japanese Army had invaded British Malaya. Split up, ill-equipped and fighting against overwhelming odds, the regiment was captured in Java, Dutch East Indies, in March 1942. Many of the men taken prisoner later died working on the Burma Railway and in the 'Hell Ships' taking them to work in Japan. Its successor unit served in the post-war British Army until 1958.
