100 years ago, British soldiers were involved in the fierce fighting of the First World War's Battle of the Somme in northern France.
The battle was one of the conflict's bloodiest, lasting for 141 days over a 15-mile front.
After the war, the family of every serviceman killed received a bronze plaque of condolence, also known as the 'Dead Man's Penny' or 'Death Penny' because of its resemblance to the coin.
1,355,000 were issued, made from 450 tons of bronze. No rank was stated, because there was no distinction made between the sacrifice of individuals.
Now, the family of a British soldier who was killed at the Somme have visited his grave to pay their respects.
