Coffin Island

No foreign Government knew anything about the Satsuma—not even Germany. Neither could the Germans possibly imagine that the Japanese had built such a monster—a battleship weighing 50,000 tons, almost a thousand feet long, mounting nine 18-inch guns that could rip the guts out of any enemy flotilla she came across.

Wind Rode was hopelessly outclassed by the Satsuma … but that wasn't going to stop Bentley from risking everything to send the larger vessel to the bottom of the sea!
