I know almost nothing about this book, its author, his ship, his pseudonym, or the attribution to him. My guess is he was a British Naval officer, possibly even a chaplain of firm pious and dogmatic conventions. He did resign from the Navy to take orders, presumably in the Anglican Church. This work is part of the genre of hortatory narratives of damnation, salvation, and the workings of providence. Although they grow tedious in time, although possibly inspirational to some, I’ve given a couple of longer narratives here to give the full flavor of the genre. I leave further research to others.
