In January 1911 Leach joined 2nd Battalion Northamptonshire Regiment, transferring to the 1st Battalion on 15 March. Promotion quickly followed and in November 1911 he was appointed Lance Corporal and in February 1913 (12) awarded the Acting School Masters Certificate. He passed classes of instruction in Transport Duties in November 1913 and in Sanitary and Water Duties in February 1914. Promotion to full Corporal followed in June 1914. His military employment sheet for March and April 1914 show him as being ‘clean, sober, reliable, hardworking. Trained as battalion scout, has a schoolmaster’s certificate and is employed as a signaller’. His father died in Leicester in 1913 and his mother at about the same time.
At the outbreak of war in August 1914 Corporal (9265) Leach J was serving with the 1st Battalion in Blackdown, Aldershot. The Northamptonshires were part of 2nd Brigade in 1st Division and following mobilisation they landed at Le Havre, France on 13 August. Although they were present at Mons, the battalion had not been engaged and went through the great retreat with just a handful of casualties. All this changed on 10 September when the battalion, acting as part of the advanced guard for the Division, moved forward to Courchamps and was engaged in the action at Priez. The battle of the River Aisne commenced on the 13th lasting until the 18th and it was for his bravery and distinguished conduct during the days of battle that Leach was promoted Sergeant. He was also Mentioned in Despatches. (LG: 17.2.1915 p167) Promotion in the field quickly followed for three of the Northamptonshires when Company Sergeant-Major Phillpot, Company Quartermaster-Sergeant Eden and Sergeant Leach were selected to be awarded immediate commissions for their services in the field. On 1st October Leach was commissioned as a 2nd Lieutenant in the Manchester Regiment; hardly given time to obtain his new uniform he joined 2nd Manchesters at Dieval on 9 October.
