One of the leading society portrait painters of his day, Sargent was commissioned to contribute the central painting for the Hall of Remembrance. Gassed is based on the scene at a dressing station as it took in casualties from a mustard gas attack on the Western Front in August 1918. Sargent travelled to France with fellow artist Henry Tonks in 1918.

The trench warfare of the Western Front encouraged the development of new weaponry to break the stalemate; poison gas was one such development. The first significant gas attack occurred at Ypres in April 1915, when the Germans released clouds of poisonous chlorine.
The gas inflicted significant casualties among the British and Canadian forces at Ypres and caused widespread panic and confusion amongst the French colonial troops. The chlorine was a strong irritant on the lungs, with prolonged exposure proving fatal. The immediate public outcry for retaliation resulted in quick adoption of defensive anti-gas measures, and new special companies of Royal Engineers were formed with responsibility for offensive gas warfare.
Poison gas was initially released from cylinders, but this required ideal weather conditions and could be very risky. In the first British gas attack, at Loos in September 1915, much of the gas was blown back into the faces of the British troops. From 1916, gas was employed in shells instead, which allowed attacks from a much greater range.
Gases used included chlorine, mustard gas (which was odourless), bromine and phosgene, and the German Army was the most prolific user of gas warfare. Although gas did not prove as decisive a weapon as was anticipated, it was effective in clearing enemy forward positions. As a result, anti-gas measures became increasingly sophisticated. Primitive cotton face pads soaked in bicarbonate of soda were issued to troops in 1915, but by 1918 filter respirators using charcoal or chemicals to neutralise the gas were common.
Although only 3 per cent of gas casualties proved immediately fatal, hundreds of thousands of ex-soldiers continued to suffer from the effects of gas for years after the war.

Small box respirator of the type first introduced in August 1916 and standard issue by the spring of 1917. This respirator consisted of a face mask with glass eye-pieces and was connected via a flexible hose to a metal 'small box' filter containing active charcoal and granules. Worn on the chest, the haversack could be opened and the mask positioned for use with the minimum delay, thus saving valuable seconds during a gas attack.
This snapshot photograph was taken from a British trench by a soldier of the 1/5th Battalion, The London Regiment (London Rifle Brigade) on the opening day of the Battle of Loos, 25 September 1915. It shows British infantry of the 47th (2nd London) Division advancing through the gas cloud released during the preliminary bombardment. This was the first major use of gas by the British, but in some sectors it drifted back towards the British trenches.
