While many publications have engaged with the events, artists and poets associated with war fought on land, the cultural history of the war at sea has been neglected. This original book redresses this imbalance by being the first study to focus on the art of war in the first half of the 20th century from a distinctly naval and maritime perspective. Drawing on the first-class collections of paintings, works on paper (including drawings, photography and posters) and archival material, such as private papers, journals and memoirs, held at the National Maritime Museum, London, the artistic response to the war at sea is analysed in the context of specific focus points such as the major arenas of naval conflict; life on board ships, aircraft carriers and submarines; the experiences of prisoners of war and the response of artists to the commemoration and legacy of key maritime events. Featuring the work of established and lesser known artists, this publication will make an invaluable contribution to war art scholarship while also presenting a little known aspect of a major museum collection.
