British Recruiting Poster, 1914
In 1918, the British Ministry of Information established a British War Memorial Committee. The aim of this group was to create a lasting record of the war, as well as a memorial to those who had fought and died in the land, sea and air wars, as well as in the “war at home”. Henry Tonks was an accomplished artist, as well as a doctor; he served in the Royal Army Medical Corps. These two skills were combined in his 1918 painting of An advanced medical dressing station, where he depicts the horrors and realities of treating injured men close to the front lines.
Other artists such as Wyndham Lewis, Paul Nash, William Orpen, Charles Simms and Stanley Spencer would go on to leave a permanent record of WWI in their art. Many more humble sketches and paintings survive, drawn by fighting men, wanting to memorialize friends, lovers, conflicts and comrades.
