Harold Beament's sketch depicts the gun battle between the burning Canadian destroyer HMCS Assiniboine and the German submarine U-210.
Both vessels maneuvered in close proximity for at least half an hour. The surfaced U-210 fired on Assiniboine with its anti-aircraft guns (right centre), damaging the destroyer and starting a fire (top left). Assiniboine had problems aiming its main guns (top centre) low enough to hit U-210, but its machine-guns kept the German crew from reaching their deck gun forward of the conning tower (centre).
