What If a Modern Nuclear Submarine Fought the Roman Empire?

What If a Modern Nuclear Submarine Fought the Roman Empire? The Mediterranean in the summer of two sixty BC is almost perfectly still. The water catches the morning light in long flat sheets, and across that light, in a formation that stretches nearly two miles from flank to flank, rows the most powerful navy the ancient world has ever assembled. Rome's warships move with the mechanical precision of a machine that took two centuries to build — oar blades lifting and falling together, bronze rams just below the surface, the low drumbeat of the stroke-keepers carrying across the water like a pulse. Hundreds of vessels. Tens of thousands of men who have spent their lives learning exactly one thing: how to destroy an enemy they can see.
