My grandfather was in the Navy both before during and after WW2. I have got a copy of his service history but it's thrown up an anomaly. According to the MOD, between 1942 and 1944, he was at the barracks in Devonport, Plymouth, then at HMS Excellent II (Evolution) which I understand was an accounting base at Portsmouth(?) then he was with HMS Keren, an assault transport vessel. Searching forces records today though, I've discovered he served on a converted tanker called HMS Bachaquero which was used to transport tanks and Bren Gun carriers. Why would this have not been mentioned in his official MOD record? Thanks for any info.
