Army

Army: The term Army had this specific Western Front meaning in the Great War. The original British Expeditionary Force of seven divisions was, early in the War, formed into three Army Corps. As additional troops arrived these were formed into additional Army Corps. On 25 December, 1914, the term Army was specially introduced and two Armies were formed by grouping the existing Army Corps. The First Army comprising the 1st, 4th and Indian Corps, was placed under Sir Douglas (now Earl) Haig; the Second Army comprising the 2nd and 3rd Army Corps and the 27th Division, was placed under Sir Horace Smith Dorrien. To prevent confusion thenceforward what had been known as Army Corps, dropped the Army and were termed Corps simply.
