This notorious First World War conflict still lives on in the memory of hundreds of islanders.
It was to take its toll on a generation of Guernseymen in the Royal Guernsey Light Infantry regiment and ultimately their families.
The battle, in a northern corner of France, marks its centenary this year, which is the reason behind the RGLI Charitable Trust's push to raise £30,000 for memorials at home and abroad to the local men's outstanding bravery in our name.
It is also why this newspaper has launched our Guernsey's Finest Hour appeal, to support the Trust's bid to provide these lasting tributes – both at the Town Church where the battalion's colours are still displayed and also near the French town of Masnieres, the scene of the RGLI's heroic fighting.
Next month the island will mark the day the troops waved farewell to family and friends – many for the final time – and departed St Peter Port harbour for the horrors of the Western Front.
Later this year in November the France memorial will be installed.
On a day when we all celebrated our liberation it is fitting we recall the sacrifice of those who have given their lives in this way, defending the rights we enjoy today.
Not only that, but organisers ensured this year's military theme embraced not just what has happened historically in two World Wars, and here in Guernsey, but what is still taking place in conflicts around the world.
Our Bailiwick will never forget how precious freedom is, always.
OUR Guernsey's Finest Hour campaign was set up by the newspaper to help the RGLI Charitable Trust's appeal to raise £30,000 for the memorials.
