The Third Army was a field army of the British Army during World War I that saw active service on the Western Front throughout the war.
First World War
The Third Army was part of the British Army during World War I and was formed in France on 13 July 1915, under the command of Lieutenant-General Charles Monro.[1]
During August 1915 the Third Army took over trench line south of the French Tenth Army, which had to keep in position for the forthcoming autumn offensive. This made the Third Army geographically separate from the other British Armies for the time being.[2] This remained the case until early 1916, when the French Tenth Army was redeployed because of French losses at Verdun and the British Fourth Army was formed.
The battles it took part in on the Western Front included:
- Battle of the Somme
- Battle of Cambrai
- Second Battle of Arras (April 1917)
- Battle of Passchendaele[3]
- Battle of Amiens (August 1918)
- Hundred Days Offensive
