History
See also: Reserve Army

The Fifth Army was created on 30 October 1916, by renaming the Reserve Army (General Hubert Gough).[1] It participated in the Battle of the Ancre, which became the final British effort in the Battle of the Somme.[2]

In 1917, the Fifth Army was involved in the Battle of Arras and then the Third Battle of Ypres. The following year, the Fifth Army took over a stretch of front-line previously occupied by the French south of the River Somme and on 21 March, bore the brunt of the opening phase of the German Spring Offensive, known as Operation Michael.[3] The failure of the Fifth Army to withstand the German advance led to Gough's dismissal and replacement by General Henry Rawlinson on 28 March and on 2 April, the army was renamed the Fourth Army.[4] Gough and his remaining staff officers were to be renamed the Reserve Army with a headquarters at Crécy-en-Ponthieu, to survey a defensive line west of Amiens as a precaution and to oversee the building of all GHQ lines.[5][6] After Gough was removed and sent home, General William Peyton took over the HQ until 23 May, when the Reserve Army title was dropped and the Fifth Army HQ was re-formed, under the command of General William Birdwood.[7][8] Although the Fifth Army was blamed for failing to hold the German advance, it was later "triumphantly vindicated".[9]

The army was not reraised during the Second World War. However, due to various Allied deception efforts, German intelligence over-estimated the number of Allied forces based within the UK by the start of 1944. While there was no specific deception effort to create the Third Army, German intelligence believed that one had been formed from Eastern Command.[10]
