Ewwwwww...
While reading through Cooke, I recalled your interest in Rogers. Then it occurred to me that Rogers had his cheek badly wounded and I wondered if you were not basing your character, at least in part, on Woodes Rogers? If so, you really must procure a copy of Captain Edward Cooke's two volume book. It is rather expensive, so I recommend the library. That's how I got mine. Curiously, I only just realized that there was a second volume (despite the fact that the spine of this book clearly says, "Volume 1" at the bottom).
He tends to go off topic and get wayyy deep into the history of the lands the privateers visited, but because of the opening summaries for each chapter, it would be very easy to skip these asides. (I am reading them because I knew almost nothing about the history of Mexico up to that time and find Cooke to be a most easy-to-read author. He does a very nice job summarizing other men's work as well.)
He also covers many things that Rogers' account doesn't mention and, like I said above, lists the full content of every single document relating to the voyage.
