This is a study of the battery on the seaward end of the mole at Zeebrugge, though slightly misleading given that the battery (north) end was almost straight, not curved as it appears here. The area with figures on and coloured yellow on the right is not a beach but the wide berthing quay on the inside of the mole and at a substantially lower level than the breakwater wall carrying the battery and the light seen at the far end. This is probably a peacetime image made on the spot after the war, with the guns still in place as abandoned relics and a small hut between them in use commercially, since it bears the word CAFE. This drawing may have been used by Wyllie for landward details in his oil painting of 'The Storming of Zeebrugge Mole, St George's Day, 23 April 1918' (exhibited at the Royal Academy, 1931), now at HMS 'Excellent', the naval gunnery school at Whale Island, Portsmouth, which shows HMS 'Vindictive alongside the Mole at roughly this point. See also PAF1756. It is likely that Wyllie visited Zeebrugge to sketch the mole for the purpose, which would put this drawing in the mid- to late 1920s.
