The last surviving veteran of WWI battle revisits the battlefield.
"Harry Patch, of Somerset, made the trip to Flanders in Belgium to recall his part in the battle which claimed 250,000 British casualties.
Mr van Emden showed him the five miles they advanced over 99 days which claimed 3,000 British casualties every day.
He was also shown a recently discovered panoramic photograph of the fields taken in 1917.
"Too many died," said Mr Patch. "War isn't worth one life."
