Sanctuary Wood is one of the larger woods in the commune of Zillebeke. It was named in November 1914, when it was used to screen troops behind the front line. It was the scene of fighting in September 1915 and was the centre of the Battle of Mount Sorrel (2-13 June 1916) involving the 1st and 3rd Canadian Divisions. There were three Commonwealth cemeteries at Sanctuary Wood before June 1916, all made in May-August 1915. The first two were on the western end of the wood, the third in a clearing further east. All were practically obliterated in the Battle of Mount Sorrel, but traces of the second were found and it became the nucleus of the present Sanctuary Wood Cemetery. At the Armistice, the cemetery contained 137 graves. From 1927 to 1932, Plots II-V were added and the cemetery extended as far as 'Maple Avenue', when graves were brought in from the surrounding battlefields. They came mainly from the communes immediately surrounding Ypres, but a few were taken from Nieuport (on the coast) and the following smaller cemeteries:- BEYTHEM COMMUNAL CEMETERY, RUMBEKE (one United Kingdom burial of October, 1918). DEERLYCK GERMAN CEMETERY (two United Kingdom burials of October, 1918; two others were taken to Dadizeele New British Cemetery). DONEGAL FARM GERMAN CEMETERY, DRANOUTRE, on the more Southerly road from Dranoutre to Lindenhoek (one unidentified British officer). EISKELLAR GERMAN CEMETERY, GHELUVELT, the cemetery of the 106th Infantry Regiment, between Veldhoek and Herenthage Chateau (one unidentified; one other burial was taken to Harlebeke New British Cemetery). FLANDERS FIELD AMERICAN CEMETERY, WAEREGHEM, one of the American Military Cemeteries (one R.A.F. Officer).
