Sapper William Arthur Lloyd was killed by a German mine while tunnelling below the Somme battlefield in 1915. Now his great granddaughter has retraced his steps to stand just feet from where he died - and where his body still lies.
The Somme, in northern France, was not only one of the bloodiest battles of World War One, but one of the bloodiest in history.
More than 1.2 million men are believed to have died during the main battle but below ground a group of soldiers, including Sapper Lloyd, fought their own private, hidden war.
Sapper Lloyd’s family, back home near Wrexham, knew little about what happened to him, other than he was killed by a German mine.
His great granddaughter Lesley Woodbridge, of Telford, Shropshire, spent seven years investigating his death.
On Sunday, with the help of a team of archaeologists studying the La Boisselle tunnels below the Somme, she descended 80ft (24m) and crawled along tunnels that in all likelihood her great grandfather had helped dig.
"We’ve just made the very last journey that he ever made and now we’re standing where he actually rests. That has to be emotional," she said.
"I never even thought I would even find out what part of France he was in, so to be standing here, just a few metres away from him, is just incredible."
