On special loan from the Imperial War Museum, the exhibition includes some 50 images by war photographers W.J. Brunell and Ernest Brooks.
Ernest Brooks (1878-1941), an official photographer on the Western Front, is best known for his images of British forces on the Somme and at Passchendaele.
The less well-known photographs he took during his official assignment to Italy in 1917-1918, have not been exhibited since 1919, and portray the plight of front-line combat troops and dispossessed Italian civilians scratching a living behind the Anglo-Italian lines.
He also produced images of many of the young Italian women employed by the British Army Service Corps, unloading railway wagons of supplies, washing British Army uniforms and preparing meals.
War in the Sunshine is curated by Dr Jonathan Black, an expert in British Art and the First World War and a Senior Research Fellow in History of Art, Kingston University, London.
War in the Sunshine runs from 13 January until 19 March 2017. More information is available here.
