At this point there's no point in consulting real history, which tells us the Spanish did indeed try to conquer Nassau at various times, if not precisely this one. For Rogers, it's a dangerous but logical move - the most or only reliable way of crushing the pirates for good.
The scene on the beach with Rackham and Flynt was excellent, too. In this narrative, Rackham has in effect lived so he can deliver that crucial message to Flynt: there's no way, given the blood lust that Rackham has witnessed first hand in Rogers, that the Governor could accede to Eleanor's deal, as much as he does love his wife.
And so a battle of battles is shaping up in Nassau. Flynt was even concerned that the pirates could beat the English. They certainly can't beat the fleet of Spanish ships of war that are approaching the harbor.
The only question left is who will live and who will die in this battle. Again, real history and Robert Louis Stevenson have given some of the major characters a lease on life (that's how I knew that Billy wouldn't be killed Sunday night). On the other hand, who will complain if Black Sails takes a liberty here and there?
I'm awaiting the next episodes.
