Unfortunately, I can't find the orginal thread in a format where I can add to it, so this is the link:http://archiver.rootsweb.ancestry.com/th/read/OXFORDSHIRE/20...
In case it's of any interest, I just thought I would post to say that all the relevant papers relating to this case (two young lads press-ganged in 1797 and released by order of the Admiralty as their family/friends fought their case) have now been located and the story is completely true. It seems that they were press-ganged in Fareham (Hampshire) and taken aboard HMS Robust.
The complete story appears in a 2011 edition of the Eynsham History Group's magazine.
Moral of the story - never (ever) give up!
