Aye, tis true. I have also read books on 'Queen Anne's War' you will not only know the language and dialect of the time plus it also talks about The Treaty of Utrecht and what made some of them become pirates like Blackbeard..
But if you read any works by Dampier, Sieur Raveneau de Lussan, Lionel Wafer and I know of more but I can't think of them right now. You will also understand more about the time.
