The Battle of Leros was the central event of the Dodecanese campaign of the Second World War, and is widely used as an alternative name for the whole campaign. After the Armistice of Cassibile the Italian garrison on the Greek island Leros was strengthened by British forces on 15 September 1943. The battle began with German air attacks on 26 September, continued with the landings on 12 November, and ended with the capitulation of the Allied forces four days later.

John ("Jake") Richard Easonsmith was a British Army soldier during World War II. He was killed in action on the Dodecanese island of Leros whilst commanding the Long Range Desert Group in 1943. W. B. Kennedy-Shaw described him as: "Brave, wise, with an uprightness that shamed lesser men, he was, I think, the finest man we ever had in the L.R.D.G."
