Colossal impudence: Protection against English gas-bombs
German illustration showing a German Red-Cross worker wearing 'protection against English gas-bombs'. The image is accompanied by indignant ILN editorial. German use of poisonous gas at the Battle of Ypres in 1915, in defiance of the 'recognised rules of war', initially appalled the British, though both sides were soon forced to use gas as a weapon.
