Amateur photographer George Hackney was sent to the war from his home in Belfast in 1915, taking his camera with him. The photo above was taken in 1916 in Belgium. The collection contains very impressive rare images, including surrendering German troops during the Battle of the Somme.
Starting from November 26, the collection will be on display at the Ulster Museum in Belfast. The photos were donated to the museum following Hackney's death in 1977, but have never been displayed before now. They were recently rediscovered in the museum's archive.
