The Army Manoeuvres of 1913 was a large exercise in the Midlands in September 1913. Learning from the Army Manoeuvres of 1912, many more spotter aircraft were used. The Manoeuvres highlighted Sir John French's deficiencies as a commander.
This comprised two infantry corps and a cavalry division.
This was an inferior force consisting largely of Territorials and Yeomanry with elements of Royal Scots Greys, 19th. Royal Hussars and Household Regiment.
THE NATURE OF THE MANOEUVRES
Three imaginary countries were involved. The central power [Whiteland] found itself suddenly confronted simultaneously by Greenland to its north with whom it had been in dispute for some time and Brownland to its south with whom it had previously enjoyed a friendly relationship. The manoeuvres involved the conflict between Brownland which crossed Whiteland's southern border with two armies and the less substantial White forces, centred on Daventry, which were to oppose them. The Manoeuvres excited much attention, both locally and nationally. King George V and Queen Mary were present along with Winston Churchill, then First Lord of the Admiralty, and Baden-Powell. There were military observers from most of the major European Powers along with representatives from the Colonies. The Times described these Exercises as essentially a practice of command function in an expeditionary force of four infantry and one cavalry divisions. 50,000 men and 25,000 horses had been brought into north Buckinghamshire and south Northamptonshire where they were dispersed for three weeks of training before being assembled to form the two forces which engaged each other over five days from 22 September. The smaller White Army formed a target force to enable the Brown Army to engage it and pursue it in its retreat. Brown's 1st Army, under Lt.-Gen Sir Douglas Haig, advanced through central Buckinghamshire to engage White forces by crossing the River Ouse to take Buckingham and Silverstone, and then sweep north to the White entrenchment which had been prepared south of Daventry. There they joined up with the left flank of the Brown 2nd Army. This army under command of Gen. Sir A.H. Paget had de-trained at Wolverton before advancing up the Watling Street through Towcester and then moving north-west to attack the White Army's prepared position south of Daventry which was where it was to make its stand. Allenby's Cavalry had been detailed to protect the Brown Force's left flank, advancing through Brackley towards the west of Daventry, where they could engage possible White reinforcements dispatched from Redditch and Leamington Spa.
