They made the ultimate sacrifice for king and country.
Over 1,000 men from Horsforth were called up to fight for their freedom in the trenches.
But over 200 men from the Leeds suburb never returned home during the First World War.
Local historian and producer Mark Saville is hoping to honour their memories by penning a book about the conflict and its impact on the town.
He has worked alongside Nancy de Dombal from Horsforth Museum and researcher Steve Brown to find out how the conflict affected Horsforth.
And now he wants to speak to families and friends of people in the town who served in the forces during the bloody conflict.
Mark, who has already released a book about the impact of the Second World War, said: “If it is not written down then these memories will be lost forever.
“I want to try and find old postcards, letters and even call-up papers that could be stored away to find out more.”
Next year will mark 100 years since the outbreak of the First World War.
Mark added: “We know that about 1,000 people from Horsforth were enlisted and 212 were killed.
“There must be someone who knows some information.
“Even if they just have minor details it could lead to something else.”
The producer has recently released a film that showcases nearly 4,000 years of Yorkshire history that took over a decade to film.
A History of Yorkshire, which is available on two DVDs, celebrates the rich history of God’s Own County.
