“Lieutenant-Colonel Lord Feversham (Charles William Reginald Duncombe), who died on the 15th of September 1916, commanding the 21st Kings Royal Rifle Corps (also known as the Yeomans Rifles) is buried here. His body was only located several weeks later when his battalion (with the future Prime Minister Antony Eden then acting adjutant) was based at Factory Corner and located it on the 10th of October 1916. Feversham's body was buried in a field to the south of the cemetery. The grave was made more permanent by his family after the end of the First World War. After the end of the Second World War, his body was moved the short distance to here. The grave beside his contains the remains of an unknown Royal Fusilier, found over 50 years later near Guedecourt and reburied here in April 2003.”
