King Ar-Pharazôn of Númenor is sailing to invade Valinor. However, Eru thinks why let them get there and sink a continent, etc - why not do this? Opening a portal to 1815 Earth, he ports the entire sailing Royal Navy to interpose between Numenor and Valinor. The admirals are told that they will get back to Earth with spoils if they take care of the Numenor fleets.

Now that Royal Navy has cannons of course and are battle hardened. The Numenors have a vast fleet with thousands of soldiers and men of mildy superhuman physical abilities.

Who wins the day?
