Cadell joined the Royal Scots in 1915 and produced a series of drawings of army life before leaving for service in France. In 1916 about fifty of these drawings were exhibited, whilst twenty were published in a book entitled ‘Jack and Tommy’, which was sold to benefit the Red Cross. These witty, quickly executed images depict soldiers and sailors on duty and on leave. Their clean lines and flat colours anticipate the style of Cadell’s painting in the 1920s. Here, three soldiers are sitting in a park watching two women walk past. The soldiers are captured in a few swift lines denoting their uniform, with the central figure smoking a pipe.
