The British Army World War One Service Records are War Office (WO) records also known as the WO363 records and the ‘Burnt Documents.’ In 1940 there was a World War Two bombing raid on the War Office in London where the records were held. During this raid, a large portion ( 60 per cent) of the 6.5 million records was destroyed by fire. The surviving service records have become known as the ‘Burnt Documents’. Although many of these records suffered water damage following the bombing raid, all surviving service and pension records were microfilmed by The National Archives, where both collections are held, as part of a major TNA conservation project.
