The Long and Winding Way, by Percy Smith from the Drypoints of War series, 1916-1919.
Percy Smith served until 1919 in France and Belgium as a gunner and experienced trench warfare. He was not an official war artist, so he had copperplates sent to him, concealed in magazines. He used them to make etchings from sketches made on the front line.
