Robert Stack stars in this sea-faring historical epic as John Paul Jones, the first great hero of the American Navy. While originally a loyal soldier of the King's army, Jones in time becomes a fervent supporter of the American Revolutionaries, and he volunteers to lead the colonists' ragtag fleet to impressive victories against the British Navy; during a battle against the British ship Serapis, Jones utters the deathless words "I have not yet begun to fight." While his brave and intelligent leadership helps win America its freedom, his appeals to Benjamin Franklin (Charles Coburn) and the other leaders of Congress to strengthen the United States Navy fall on deaf ears; Jones is eventually branded a troublemaker, and in time, he is ordered to Russia, where he is to help guide the fleet of Catherine The Great (Bette Davis). Jones leads the Russian Navy to stunning victories in the Black Sea, reestablishing his reputation as one of the great military minds of his day. John Paul Jones also features a rousing score by the great film composer Max Steiner.
