Khaki service dress replaced the scarlet tunic as the principal uniform, and the Army Council attempted to remove the flash during the First World War, citing the grounds that it would help the Germans identify which unit was facing them. As Fusilier officer Robert Graves reported, "the regiment retorted by inquiring on what occasion since the retreat from Corunna, when the regiment was the last to leave Spain, with the keys of the town postern in the pocket of one of its officers, had any of His Majesty's enemies seen the back of a Royal Welch Fusilier?," and the matter remained "in abeyance throughout the war." The efforts of the regiment to retain the distinction was further reinforced at a medal ceremony when King George V saw an officer of the regiment in the line. He ordered an About Turn and seeing the flash still on the tunic said "sotto voce", "don't ever let anyone take it from you!" The wearing of the flash on service dress was extended to other ranks in 1924.
