1776: A decade of simmering tensions is finally coming to the boil. Determined to cast off the chains of British tyranny, the rebel government of Philadelphia has authorised the creation of the United States Navy - a brazen act of American aggression against the greatest maritime power in the world.

Captain Isaac Biddlecomb sets sail in the Charlemagne on a daring mission to raid the British store of arms on New Providence Island in the Bahamas. Yet his greatest enemy is an undisciplined crew on the brink of mutiny.

Beset by betrayal and treachery, Biddlecomb must find a way to unite his men against a cruel and common foe ... as the British Navy prepares to sink the Charlemagne under the merciless blasts of its guns.
