I am hoping that someone can help me trace something about my grandfather, Robert Evan Roberts, who served on HMS Racehorse during WW2.

When my grandmother passed away we found his medals from WW2 and noticed that one medal has what looks to be an oak leaf upon it. When this was shown to a local dealer in war memorabilia has stated that the oak leaf means he was "Mentioned in Dispatches".

So we take this to mean that he obviously did something but at this point in time we do not have a clue what is was that he did.

He did not like to talk about his time during the war but we do know that he was in Burma on HMS Racehorse.

Does anyone have a way to be able to find out what is was that he did to get himself mentioned in dispatches?

Any help would be greatly appreciated.
