The series of 100 images, their colours making it seem as if the conflict came to an end just yesterday, has been painstakingly produced to commemorate the 100th anniversary of the Armistice.
Among the photographs is one of a wounded German prisoner of war, both eyes bandaged, being gently led along a railway line by a British tommy in 1916, a French soldier behind them weighed down by the heavy tripod of an early camera.

Another shows gunners from the Royal Garrison Artillery pushing a light railway truck filled with shells and British officers standing outside the mouth of a German trench in Messines, Belgium, after its capture in 1917.
Other, equally striking pictures show King George V sitting next to an army commander on the site where Thiepval Chateau stood before its destruction during heavy fighting in September 1916, and a more light hearted one of a soldier receiving a haircut from an Alpine barber on the Albanian front.
Tom Marshall, who spent weeks colourising the original black and white photographs, said: I began colourising black and white photos professionally in 2014, coinciding with the centenary of the outbreak of WW1 in 1914. Around the world there was a renewed interest in a war that had not been fresh in the public memory for many years.
To mark the centenary of the end of the First World War, I decided to collate 100 images Ive colourised in tribute to the men and women who lived through the war, and those who lost their lives.
The Nottingham-based photo colouriser added: I included men and women of several nationalities, races and religions, as the entire world was affected by the war, and I hope the photos will show an insight into the lesser known stories and events.

Mr Marshall, of PhotograFix, appealed for people to make a donation to the Royal British Legions Poppy Appeal – or to a similar appeal in their home country – as a way of remembering the men captured in his images, as well as the estimated nine million combatants and seven million civilians who died as a direct result of the war.
Poppies have been put up all around the town as a mark of respect for soldiers who paid the ultimate price in the 1948-18 conflict.
Mr Marshall said: Since 2014 I have been very fortunate to have been able to work on exhibitions, press articles and books commemorating significant WW1 anniversaries, but I have also been honoured to work on personal family photos, which all have unique insights into what was truly the first global conflict.
By adding colour to images previously seen only in black and white he hopes to convey to a new generation the grim reality of a war.
Now the pity of war so powerfully evoked by the poets of the trenches a century ago has, thanks to Mr Marshall, a modern, colour drenched hue.
This week will mark 100 years since the guns of First World War finally fell silent after four years of bloody conflict which devastated Europe
When the US declared war on Germany on April 6, 1917, the Allies had already endured over three years of carnage.
The famed Harlem Hellfighters were the first to join the fight on the frontlines under French command.
As the Americans began to send more troops across the Atlantic, Germany was anxious to score a victory before the majority of their forces arrived.
In the midst of the Bolshevik Revolution, Russia could not sustain its war effort. The dissolution of its forces freed German soldiers to the east, and the Central Powers ranks along the western front swelled.
That plan backfired, and with the additional US troops, the Allies were able to counter a string of German offensives, starting with the first US-led assault in a small village near the Somme called Cantigny.

It was there the Americans decided to attack. As they dug in to prepare for the days ahead, their French counterparts retreated, and advised the US Marines do the same.
On June 6, 2018, the US forces launched a three-week battle in which both sides would suffer debilitating losses.
On the first day of fighting, US forces suffered over 1,000 casualties. The Germans defended against nine assaults, until June 26, when a combat report relayed the victory.
Accounts vary as to the precise wording used by Marine Maj. Maurice Shearer, but the gist was this: “Woods now U.S. Marine Corps entirely.”

Suffering a major defeat at Belleau Wood, German General Erich Ludendorff had one final chance to advance across the river Marne towards Paris.
But the Allies held him off, and on July 18 launched a counter-offensive that would be considered the turning point of the war.

Gen. Ludendorffs plan was to divert the Allies away from Flanders, where he would launch another offensive.
But the Germans suffered a swift defeat, and by early August 1918 the Allies had recaptured Soisson to the north.
