Lorettoschlacht
The ridge fell under German control in October 1914, during the Race to the Sea, as the Franco-British and German forces continually attempted to outflank each other through northeastern France. The French Tenth Army attempted to dislodge the Germans from the region during the Second Battle of Artois in May 1915 by attacking their positions at Vimy Ridge and Notre Dame de Lorette. During the attack, the French 1st Moroccan Division briefly captured the height of the ridge, where the Vimy memorial is currently located, but was unable to hold it owing to a lack of reinforcements. The French made another attempt during the Third Battle of Artois in September 1915, but were once again unsuccessful in capturing the top of the ridge. The French suffered approximately 150,000 casualties in their attempts to gain control of Vimy Ridge and surrounding territory.
