The battle of the Somme remembered
The battle of the Somme has defined our idea of the First World War. On the first day alone, 19,240 British soldiers lost their lives. The Somme campaign wore on for five months and, in all, more than a million soldiers from the British, German and French armies were wounded or killed. The British army advanced just seven miles.
For future generations, the battle became a symbol of the futility of war.
James Heffer was just 16 when World War One broke out, and by June 2015 he was in the trenches as part of The Cambridgeshire Regiment.His son, the journalist Simon Heffer, explains how his father ended up fighting at such a young age.
He also reads some extracts from James' diary, written as the Battle of the Somme commenced.
How WW1 changed the way we bury our war dead

Camilla visits great uncle's grave
The Duchess of Cornwall has laid a wreath at the grave of a great uncle who was killed during the Battle of the Somme while serving with the Coldstream Guards.
It was the first time Camilla, accompanied by the Prince of Wales, had visited Carnoy Military Cemetery, where Cpt Harry Cubitt is buried.
He was the eldest of three sons killed during the war and the duchess told reporters a photograph had been placed beside the grave, although she did not know who left it.
"I have never seen a photograph of him before," she said.
"It is such a long time ago and it made me suddenly realise what it must have been like for my great grandparents, to have three sons within 18 months of one another being killed."

The British gain some ground
History of World War One
By the end of the day the British had gained just three square miles of territory.
On the right wing of the Fourth Army forward trenches were captured. Across the rest of the line the battle was a disaster for the British, with the exception of the Ulster Division which was holding the Schwaben Redoubt. The French forces managed to gain land up to the German second line.
The British forces suffered 57,470 casualties, including 19,240 fatalities.
In the vaulted chapel of Old St Pauls Episcopal Church in Edinburgh is a war memorial from where this evening's epitaph is recorded. The church is hidden down a close, in what was once the heart of Edinburgh’s old town slums. It gave up many of its men to the local regiments – five of them died on 1 July 1916 alone.
In the 16th Royal Scots McCrae’s battalion were: David Newton Smart, the eldest of three brothers to die in the war, Edward Anderson, the 19-year-old son of a type founder, and William Tait, a plumber’s apprentice.
