Hello All, I am trying to find out which Bomb Disposal Units - RE, RN, RAF or HG - operated in west Wales - particularly Pembrokeshire - during WW2. This research is part of a wider project re: the history of Pembroke Dock. I have a very long list of unit records at TNA, but apart from trawling through them all, how might I find which units are of interest re: West Wales? I know that there is huge expertise on this forum and any info, guidance, pointers would be much appreciated. Many thanks in anticipation.
