On 24th September 1915 he embarked at Southampton with the 75th Field Ambulance, then disembarking at Havre the next day, entered the war in France on 25th September 1915. He was admitted into his unit on a few occasions with minor injuries and sickness, then on 11th April 1918 was admitted with fatal wounds received in action. An officer wrote: “Staff Sergt. Boxall has always done splendid work for his unit, and his loss is one we shall find it hard to replace. During the recent fighting his conduct was magnificent, and I am pleased to be able to inform you that his gallant services have been recognised by the award of the Military Medal.” The award was for bravery on the battlefield. Frederick was the foster son of Susan Aggett of 53 Clifford Street, Chudleigh, Devon.
