History (Source: Wikipedia) 

A new monument for all war victims was unveiled on the bank of the Steenbeek (brook) in the Melkweg (street) in Langemarck on 27 September 2008. Harry Patch, a British war veteran, crossed this brook in 1917 before the attack on Langemarck. Not only did he lose three of his best friends in this attack but he was also heavily wounded. After one year's rehabilitation he was sent to the front in Ypres once again in 1918. When he returned, he took the initiative of erecting this monument and commemorating all victims who had offered themselves pointlessly. He died in England in 2009, at the age of 111.

The municipality of Langemarck-Poelcapelle made the land available for the memorial stone. The Commonwealth War Graves Commission manufactured the stone and is responsible for its maintenance.  In the beginning of 2018 the Memorial Stone was stolen but already a few months later, on 30 October, a new one was placed.

Henry John Patch (17 June 1898 – 25 July 2009), dubbed in his later years "the Last Fighting Tommy", was an English supercentenarian, briefly the oldest man in Europe and the last surviving combat soldier of the First World War from any country. He is known to have fought in the trenches of the Western Front. Patch was the longest-surviving soldier of World War I, but he was the fifth-longest-surviving veteran of any sort from World War I, behind British veterans Claude Choules and Florence Green, Frank Buckles of the United States and John Babcock of Canada.
