Montague Percy was the son of the Hallaton Station Master, Robert Killingrey at a time when it was a most important role in the village and a large employer with fifteen men working at the station at that time. He was a bright young boy with a talent for art. After schooling in Hallaton he gained entrance to Wyggeston Boys School but was only there for one year. In 1911, by then aged 19 he was working as an apprentice at Boots the Chemist in Market Harborough. Not satisfied with this routine employment in December of that year, he volunteered for the army and joined the Royal Field Artillery for a three year term plus a further nine years in the Reserve. His service number was 68099. He appeared to have underlying health problems because in February 1912 having only just completed some of his basic training, he was seriously ill with pneumonia and complications and in a military hospital until 12th April before being given a month’s home leave. Despite ill health he had made good progress in the army because on the day war broke out, 4th August 1914, he was promoted to Acting Bombardier – the equivalent to corporal. His unit, 37th (Howitzer) Brigade RFA part of 4th Division landed in France on 23rd August. They were immediately in the thick of the fighting attempting to stem the tidal wave of the German advance. Casualties were very great. Percy was not wounded but on 23rd October he was badly injured by a gun wheel going over his foot and crushing it. He was shipped back to England and admitted to the Royal West Sussex Military Hospital in Chichester. Whilst there he was X-rayed and was found to have an “abnormality at the base of the lung”. He was in hospital, for many months and military authorities eventually decided on a medical discharge which came into effect on July 28th 1915. The army had lost a good young man as his records show “Very good character. A well spoken and intelligent young man, a hard worker and conscientious. A good clerk.” He came home seriously ill and succumbed to meningitis on 8th December 1915 and was buried in Hallaton Cemetery. The Market Harborough Advertiser of December 21st 1915 reported:- “The Citizen Corps followed in honour of the brave young soldier who had “done his bit” for King and Country, whilst the Union Jack flew above the many wreaths which entirely covered the bier. The Funeral Service was fully choral: the Psalm and Hymn “Thy way, not mine, O Lord” and “Now the labourer’s task is o’er”, with the “Nunc Dimittis” were sung, concluding with “The Dead March” in “Saul” impressively rendered by the organist.” Although his death was without doubt hastened by his war service, because he had been discharged he is not on the Commonwealth War Graves Commission register but his name was carved with pride on the village war memorial.
