It was a simple yet so moving tribute.
And across Britain, many millions took part in the Lights Out project to mark the centenary of World War I, which cost the lives of so many young soldiers.
Households, businesses and public buildings were urged to turn off the lights at dusk on Monday, the anniversary of Britain’s entry into the war.
Instead, they were asked to place a candle or lantern in the window or doorway.
Among those taking part were John and Denise Dyson, who live in a cottage in Wilberlee, Slaithwaite .
The couple lit candles and put them in the front window of their cottage as they paid tribute.
Mrs Dyson, 74, and her 72-year-old husband have a daughter.
Mrs Dyson said: “My father was in the Army, in the Second World War, and we always like to remember those who have given their lives.
“It was a way of doing that on the anniversary”
Events to mark the centenary are continuing.
An exhibition to commemorate the 100th anniversary and to remember all those of Kirkheaton who fought and gave their lives will be opened this week.
There will be an official opening on Saturday, August 9, at 11am at Kirkheaton Parish Church by Paul Rogers, Professor of Peace Studies Bradford University, with talks by a local WW1 historian.
The exhibition has been organised by Kirkheaton Family History Group and includes extensive research information on the World War One casualties, artefacts and ,medals.
Exhibition contributions have been received from around the world and include a WW1 Death Medallion and a notebook still encrusted with trench mud.
Meanwhile the Duke and Duchess of Cambridge joined Prince Harry at the Tower of London to symbolically plant poppies to commemorate British and Commonwealth dead from the First World War.
The three young royals each planted a ceramic version of the red flower so synonymous with the conflict in a powerful and enormous art installation at the London landmark.
Blood Swept Lands And Seas Of Red, in the Tower’s moat, currently consists of 120,000 poppies but more will be added over the coming months until there are 888,246 on Armistice Day, November 11, one for each British and Colonial death during the war.
