Football remembers

There is a new memorial at Britain's centre for rememberance -- a large area of woodland that exists to honour service and sacrifice. But from today it also honours those who, for a brief while , did not have to put their lives at risk for King and Country -- a moment in history that has become folklore, when on Christmas Day in 1914 the German and British forces living in trenches, sometimes no more than fifty metres away from each other, stopped fighting. They exchanged gifts, sang carols and famously even played a game of football in no man's land. Robert Hall reports for BBC Radio 4's The World at One.
