When the First World War ended, war graves existed wherever fighting had occurred meaning that locations and sites of many graves were not known with individuals unburied particularly in locations where there were intense battles. Because of this the majority of the casualty records were established. The Commission was inaugurated to a provide perpetual commemoration to those who had died during the war. To accomplish this aim the Commission had to collect details for each individual and the location of their grave or where they had died.
The military authorities supplied casualty lists and controlled the work of Labour Companies and Graves Concentration Units which were tasked with searching for the graves and remains of the war dead and conducting the battlefield exhumation and reburials which resulted.
If burials were in established burial grounds with clearly marked graves then the graves were simply recorded and registered. In cases where bodies required exhumation and reburial attempts were made to identify the individuals. Old battlefields were searched for small cemeteries of less than 40 graves, isolated graves and the previously unburied dead. The bodies/remains were taken to 'concentration' cemeteries which were newly created or established within existing burial grounds.
Exhumation squads were methodical in their searches because their search for anything that would help identify a fallen comrade was paramount. Battlefield conditions often meant that vital indicators were already lost because of the circumstances in which the casualty had died, subsequent actions in the same location or environmental and weather conditions which made it impossible to identify the bodies which were located. Details were recorded about each body recovered, including where the remains were found, any regimental insignia or other means of identification. Items which could be returned to the family were recorded by the Effects Branch.
These details were written on a ticket which was then attached to the remains prior to removal and reburial. The cemetery officer on reburial would record all the information that had been written on the original ticket in the cemetery burial return together with the plot, row and grave number. The forms were passed to the Army Burial Officer who sent a copy to the Directorate of Graves Registration The registration officer was then responsible for registering the new graves and for preparing comprehensive reports of the new cemeteries. The grave registration, concentration and exhumation records were passed to the Commission which form the basis of the information they have for everyone commemorated by them.
Nearly all of these documents were handwritten reports produced in the field in all conditions. Some of the records were typed up by administrative staff at base camps in the various locations. It follows therefore that there may have been mistakes so the Commission made every effort to contact the individual's next of kin to additionally verify the records.
After the wars had ended verification forms were sent to next of kin in order to confirm the details held were correct and to solicit any additional information to make sure the details recorded on the original documentation were correct or that corrections were made and the documents annotated as required. The core records enabled register entries and headstone schedules as well as other documents to be compiled.
The Commission then created digital images of the records and scanned the casualty details in the cemetery and memorial registers which form the basis of the searchable database on the website.
