Loos-en-Gohelle (Pas-de-Calais)
The Battle of Loos (25 September to 8 October 1915) was part of a combined Anglo-French offensive in Artois, aiming to break through the German lines in the mining basin around Lens. British forces had to advance through this open country from the right towards Loos and Lens. The Germans occupied strong defensive positions, including the slag heaps in Loos, offering obvious strategic advantages. The offensive achieved little territorial gains, in spite of the use of poison gas by the Allies. Losses were very high (some 60,000 British and 26,000 German casualties).
On the horizon, to the right can be seen the Lone Tree, an obvious landmark in the flat country, then located in no-man's land. More to the centre is the British Memorial and Dud Corner Cemetery.
