I am meant to be marking your essays, but stumbled upon this website from the BBC.
It contains 13 unabridged interviews form survivors from the First World War. They were recorded in 1964 for the BBC Great War series. Each is about 17 minutes long, and they reflect different aspects of the war. The humility of the people interviewed make them amongst the most moving things I have seen in a long time, and I warmly recommend them to you.
Mr Kydd.
