In December 1775, Parliament passes the Prohibitory Act, which outlaws American trade with foreign nations. All American ships (regardless of the owner's political sympathies) are considered enemy vessels that can be captured by the British Navy and declared prizes of war, their cargoes sold to the highest bidder. Declaring the colonists to be rebels and outlaws, the act removes the colonies from the king's protection. Congress learns of the act in February 1776. The question of foreign support and America's trade with foreign nations is now more important than ever. Will foreign allies dare to trade with America if American ships are subject to such hostile conditions? In March 1776, Congress takes its own decisive action in its struggle to control the seas.
