Help Needed on research of WW1 RAMC soldier in Great Britain: Research, Documentation & History Posted yesterday at 12:57 I am interested by this post, as I belong to a living history group which portrays the Canadian Army Medical Corps, Great War period. I would have thought that a transfer from the RAMC to the RE would be unusual but presumably something in his civilian job /skills set suggested to the authorities that he would be more useful on railways or canals than as a stretcher bearer or medical aide. Tony, I'm also very interested to see that he was given a new serial number. Was that common? In the Canadian Expeditionary Force men were re-assigned on reaching England, or even in Canada, but the originally issued serial stayed with the soldier throughout his service in the vast majority of cases, which can be confusing. Each of the 240+ battalions was given a block of numbers to issue, to avoid duplication, but as many units were broken up form reinforcements on reaching the UK, so the block prefix only really tells one which battalion he enlisted in.
