While it is certainly true that the Duke of York's regiment was the first marine unit in the British establishment, it was disnanded in 1689. This set a pattern that was followed until the Seven Years War (when a permanent Corps was established in 1755), where marine regiments would be raised during wartime and disbanded when peace returned. Beacuse of this, it is my undertanding that the Royal Marines do not trace their descent from these pevious units.
