John Gallacher was born in Maghera. From his service number it can be deduced that he enlisted shortly after the outbreak of war. Private John Gallacher was serving with the 1st Battalion of the Irish Guards when he was killed in action on 18th May 1915. Private Gallacher has no known grave and is commemorated on the Le Touret Memorial in Richebourg, France.
Le Touret Memorial is located at the east end of Le Touret Military Cemetery, on the south side of the Bethune-Armentieres main road. From Bethune follow the signs for Armentieres until you are on the D171. Continue on this road through Essars and Le Touret village. Approximately 1 kilometre after Le Touret village and about 5 kilometres before you reach the intersection with the D947, Estaires to La Bassee road, the Cemetery lies on the right hand side of the road. The Memorial takes the form of a loggia surrounding an open rectangular court. The court is enclosed by three solid walls and on the eastern side by a colonnade. East of the colonnade is a wall and the colonnade and wall are prolonged northwards (to the road) and southwards, forming a long gallery. Small pavilions mark the ends of the gallery and the western corners of the court.
