It was amid the terror of the trenches that they stopped and put on a brave face for their families.
Amid the three-month Battle of the Somme in 1916, thousands of British, Australian and French soldiers posed for photos that were later sent home to relatives.
The 4,000 glass plate negatives of mostly unidentified Western Front troops were uncovered in 2010 in an attic in a farm house in northern France, by author Ross Caulthart and military historian Peter Burness.
Now, with only a fraction of the First World War troops having been identified, researchers are calling on the public and potential relatives to help put names to their faces.
In Australia, around 250 of the 800 Australian soldiers who feature have been identified, but in Britain, historians have only been able to trace 100 of the 1,500 Britons who are pictured.
The images were taken by French couple Louis and Antoinette Thuillier, who lived in the village of Vignaport. Their photos now form what is called the Thuillier Collection.
Vignaport, just 30 miles from the front lines, acted as a staging post, where soldiers could rest and prepare for battle.
At least 420,000 British men were killed over several months on the Somme, along with 195,000 French troops and 450,000 Germans.
On just the first day of the battle, the British Army lost 20,000 men, with a further 40,000 injured.

The Thuilliers hit upon the idea of charging a small fee to take portraits mages of soldiers as they sought to capitalise on the hive of activity that Vignaport became during the war.
Their images were printed onto postcards, allowing soldiers to maintain a fragile link with soldiers back home.
The images capture what military life was like for the troops as well as some of the friendships and bonds formed between the soldiers and civilians.
Some of the images have been displayed in a museum in the Thuilliers’ former farmhouse since 2018.
Alice Orzechowski, assistant director of the Vignacourt 14-18 museum, told The Times that it is ‘more difficult’ to identify British men because of ‘limited access’ to archives and the fact that it costs money.
Appealing for help, she called on both researchers and ordinary Britons to help ‘take part in this research adventure’.
Some of the images date from the 1916 offensive, whilst others were taken in 1917 and 1918.

For much of the First World War, the small French village of Vignacourt was always behind the front lines – as a staging point, casualty clearing station and recreation area for troops of all nationalities moving up to and then back from the battlefields on the Somme.

Mr Coulthart’s 2016 book, The Lost Tommies, displayed some of them for the first time. The original glass plate negatives were bought by Australian businessman Kerry Stokes.
The plates of British, American, French African, Nepalese and Indian soldiers are housed by Mr Stokes’s museum, the Stokes Collection.
Mr Coulthart told The Times that he had not been able to find British museums willing to preserve, restore and digitise the images of British men.
He claimed that on visiting museums in the UK, his inquiries were met with ‘disinterest and unhelpfulness’
Battle of the Somme: One of the deadliest fights in history
Lasting 141 days, the Battle of the Somme was the bloodiest battle of the First World War.
The British suffered 420,000 casualties, including 125,000 deaths, during the intense fighting. Another 200,000 French troops and 500,000 Germans were either killed or wounded in action.
It is estimated 24,000 Canadian and 23,000 Australian servicemen also fell in the four-month fight.

The British and French joined forces to fight the Germans on a 15-mile-long front, with more than a million-people killed or injured on both sides.
The Battle started on the July 1, 1916, and lasted until November 19, 1916. The British managed to advance seven-miles but failed to break the German defence.
On the first day alone, 19,240 British soldiers were killed after ‘going over the top’ and more than 38,000 were wounded.
But on the last day of the battle, the 51st Highland Division took Beaumont Hamel and captured 7,000 German prisoners.
The plan was for a ‘Big Push’ to relieve the French forces, who were besieged further south at Verdun, and break through German lines.
Although it did take pressure off Verdun it failed to provide a breakthrough and the war dragged on for another two years.
