The Gas Attack at Hulluch was an engagement in World War I, from 27 to 29 April 1916, involving the 16th (Irish) Division of the British Army's XIX Corps.
The Royal Inniskilling Fusiliers on the night of the 27th suffered a heavily-concentrated German chlorine gas attack near the German-held village of Hulluch, a mile north of Loos.
The German began preparing for the attack during April when they placed about 7,400 cylinders along a 3 km front. The Germans began an attack by first releasing smoke, followed by the gas 1½ hours later from 3,800 cylinders. This subterfuge caused the British Army troops to dispense with their Phenate-Hexamine Goggle helmets after the smoke was released, resulting in 549 casualties during the attack, of whom 139 were killed.
Other units of the 16th Division, including the Royal Irish Rifles, the Royal Munster Fusiliers and The Royal Dublin Fusiliers were called in to stem the German attack.
On the 29th, the Germans attacked with gas again but this time the wind blew the gas back upon them. 232 British troops were killed and 488 were wounded, with a partial German casualty list of 453.
Hulluch was one of the most heavily-concentrated gas attacks of the war.
