It is also known that Pepys was planning to write a history of the navy and that he was gathering material for this task, but this project also was never finished. It is considered likely that King Charles was aware of Pepys' plans and presented him with two of the rolls either as a gift or as payment for the intended publication of the escape story. The second roll could not be located at that time, and it was not until 1690 that it was discovered by Henry Thynne, keeper of the royal library 1677–89 and a close friend of Pepys.
