Under cover of gas and smoke..., 1916.

Under cover of gas and smoke we break through to Serre and Thiepval’, 1916. The Germans first used gas against the French during the capture of Neuve Chapelle in October 1914 when they fired shells containing a chemical irritant that caused violent fits of sneezing. In March 1915 they used a form of tear gas against the French at Nieuport, and the following month chlorine gas against the Canadians at Ypres. These early experiments were but a small taste of things to come and as the war progressed all sides developed ever more lethal gases including phosgene and mustard gas. From a collection of one hundred and one stereoscopic photographs in box one of two entitled ‘The Great War’ including the official series. With stereoscopic viewer. Stereographs consist of two identical photographs paired in such a way that when seen through a special viewing instrument, a stereoscope, they appear as a three-dimensional images. By 1899 the photographs were mounted on thick card that was given a slight curvature to increase the illusion of depth. Associated with World War One, Western Front (1914-1918).
