Following the institution of the RAF Ensign in 1921, there were occasional suggestions that it should be flown on the Cenotaph. These suggestions were rejected, as the RAF Ensign had not been created until after the Great War, and the RAF itself had only been established for the last seven months of the War. At this time a Union Flag, a White Ensign and a Red Ensign were flown on one side of the Cenotaph and a Union Flag, a White Ensign and a Blue Ensign were flown on the other side.
