There is no record of a Prisoners of War Camp (Kriegsgefangenenlager) under the name of Glageon. The CWGC states: "The Communal Cemetery was used for the burial of German soldiers and Allied prisoners from September, 1914, to August, 1918; the Extension was then begun, and was used until the following October". On the cemetery plan the extension between August and October is larger than the original commune's cemetery. Note the CWGC description does not state it was a prisoners of war camp. It states Allied prisoners were buried there, but if you search the internet for Glageon POW you see the CWGC information repeated with the suggestion of there being a camp there.
