MARKET BOSWORTH SOLDIER KILLED

Private John Howard Allcoat, of the Leicestershire Regiment, the eldest son of Mr and Mrs Allcoat, of Market Bosworth, was shot dead by a German sniper on November 16th. He and his brother, Private W. N. Allcoat, had been fighting side by side with the Leicesters in France and Belgium for the last 18 months. Twenty-two years of age, he was of magnificent physique, standing over 6ft 2in, and was invited on enlisting to join the Life Guards, but refused, saying, “Where my brother goes, I go, and where he fights, I fight.” The two were together when John was shot dead. Captain T. C. Howitt, of the Leicesters, writing to the bereaved parents, says that the deceased was admired by all the officers and comrades. He did excellent work in the company, and one could not possibly count the number of Germans he had accounted for. It was a great shock to his brother, but he stood it finely. Private N. W. Allcoat, deceased’s brother, is mentioned in a number of letters Mr and Mrs Allcoat have received from officers. He helped carry his brother’s body to the mortuary, and then went back to his sniping-post, and after waiting and watching for some hours, shot the German who killed his brother, thus avenging his death.
