Lance Sergeant Frederick Hartwell, who died on 9th October 1916, is buried in Pozières British Cemetery, Ovillers La-Boiselle, Somme, France (III. T. 9). Pozières is a village some 6 kilometres north-east of Albert and the cemetery, which is enclosed by the Pozières Memorial, is a little south-west of the village on the north side of the main road (D929) from Albert to Pozières.
The village of Pozières was attacked on 23rd July 1916 by the 1st Australian and 48th (South Midland) Divisions, and was taken on the following day.
Plot II of Pozières British Cemetery contains the original burials of 1916, 1917 and 1918. The remaining plots were made after the Armistice when graves were brought in from the battlefields immediately surrounding the cemetery, the majority of them being soldiers who died in the autumn of 1916. Lance Sergeant Hartwell was one of those whose body was exhumed and relocated at Pozières. A Burial Return of The Canadian Graves Detachment reveals that Lance Sergeant Hartwell was reburied at Pozières on 30th June 1919. Some of the more important burial grounds from which British graves were concentrated to Pozières British Cemetery were: Casualty Corner Cemetery, Contalmaison; Danube Post Cemetery, Thiepval; Nab Junction Cemetery, Ovillers-la-Boisselle.
There are now 2,760 Commonwealth servicemen buried or commemorated in this cemetery. The cemetery and memorial were designed by W H Cowlishaw.
