Sorry I no longer have the reference material but several years ago i read that when a salvage group located the San Jose that the government changed the contract from something like 60 % to the salvors to 80% to the government. the salvors left and took the location with them. a Brit Captain was supposedly court martialed for firing on the ship and blowing it up. This would seem to indicate somewhere in the Admiralty records there is an account of the battle (locations of the ships involved) and contents of the San Jose.
