The tragic losses of Loos, the largest British battle of 1915, were felt throughout every village and town in Scotland but for Dundee it was its "darkest hour".

Half the 72 battalions taking part in the three-month battle belonged to Scottish regiments. Of the 30,000 Scots who fought, 7,000 were killed.

The Loos British Cemetery was begun by the Canadian Corps in July 1917 for casualties from the Battle of Hill 70. The remainder of the cemetery was formed after the Armistice.

According to the National Army Museum, the Battle of Loos saw 50,000 British casualties, almost double the number of German losses, and was the first time the British Army used gas as a weapon.
