Tonight on BBC 1 9.00pm and on BBC 1 HD Tonight, 9:00pm Jeremy Paxman presents a four-part documentary series charting how the First World War affected the lives of the British people, and created what we know as modern Britain. In this programme, Paxman traces the story of the dramatic early stages of the war, from stunned disbelief to the mass recruitment of volunteer soldiers. Fear of invasion grips the country, Boy Scouts guard bridges, and spies are suspected everywhere. For the first time, British civilians are fired on by enemy ships and bombed from the air. Paxman meets a 105-year-old eyewitness to the shelling of Hartlepool, who describes how she thought the Germans had landed.
