They are the fallen heroes of a war fought on a scale never before seen in human history.

And now a historic set of books listing the final resting place of every British and Colonial serviceman who died during the First World War is set to go under the hammer in Norfolk.

The Imperial War Graves Commission index up for auction is a set of 64 volumes and one of only two copies of the document in existence.

It lists the location of the graves of British, Australian, Canadian and South African soldiers and sailors who lost their lives during The Great War, or the location of the memorial on which they are commemorated if they have no grave.

The volumes list around one million names, along with their regimental or official number.

They were originally owned by the Imperial War Museum, which sold them in 2016 following a programme to digitise the records.

The only other copy is owned by the Commonwealth War Graves Commission.

Oscar Crocker, militaria expert at Keys Auctioneers, said: “This is a breathtaking and very rare historical document, listing the resting place of every single soldier and sailor who gave their lives for their country during the First World War.

“It is sobering to see listed on every single page the names of 30 fallen servicemen, a total of around one million in total. 

“Each of them had an individual story to tell, and each death was a tragedy for their family and loved ones.”
