Former war reporter Jon Snow presents a timely reminder of how British artists have expressed and defined our response to the horror of war and, in the process, have triggered a debate about the role of art in British life. As the grandson of a First World War general, it's a story with a personal resonance for Jon.
A hundred years ago, artists were the first to challenge the view that war was all about victory and glory. Jon, a keen amateur artist himself, traces this legacy from the artists of the First World War - Richard Nevinson, Paul Nash, Stanley Spencer - right up to the work of contemporary artists such as John Keane, Jeremy Deller and Steve McQueen.
Britain's war artists have pushed the boundaries in their drive to bring home to us the true cost of war. We once celebrated war's valour and glory, but they have encouraged us to feel its pain and tragedy. They have given us an artistic legacy that will continue to provoke and to move generations to come.
