Gas rattle used by Lieutenant J T Colledge, Royal Horse Guards, 1918 (c).
The introduction of gas warfare on the Western Front in 1915 meant that rattles, horns and whistles were soon adopted as means of warning troops and giving them time to put on protective equipment during gas attacks. Rattles could also be used to simulate machine-gun fire.
