Eight decades on, relatively few people recall the historical significance of Aug. 15, 1945. Yet, the surrender of Japan on that day, ending the Second World War, was a pivotal moment in 20th-century history. Each year, Victory over Japan Day, known as VJ Day, commemorates that surrender. While Victory in Europe Day — May 8, 1945 — marked the end of the war in Europe, many thousands of armed forces personnel had continued to fight in Asia in what is sometimes seen as a forgotten conflict.
