A letter of marque and reprisal was a government license in the Age of Sail that authorized a private person, known as a privateer or corsair, to attack and capture vessels of a foreign state at war with the issuer, licensing international military operations against a specified enemy as reprisal for a previous attack or injury. Captured naval prizes were judged before the government's admiralty court for condemnation and transfer of ownership to the privateer.
A blockade runner is a merchant vessel used for evading a naval blockade of a port or strait. It is usually light and fast, using stealth and speed rather than confronting the blockaders in order to break the blockade. Blockade runners usually transport cargo, for example bringing food or arms to a blockaded city. They have also carried mail in an attempt to communicate with the outside world.
Prize money refers in particular to naval prize money, usually arising in naval warfare, but also in other circumstances. It was a monetary reward paid in accordance with the prize law of a belligerent state to the crew of a ship belonging to the state, either a warship of its navy or a privateer vessel commissioned by the state. Prize money was most frequently awarded for the capture of enemy ships or of cargoes belonging to an enemy in time of war, either arrested in port at the outbreak of war or captured during the war in international waters or other waters not the territorial waters of a neutral state. Goods carried in neutral ships that are classed as contraband, being shipped to enemy-controlled territory and liable to be useful to it for making war, were also liable to be taken as prizes, but non-contraband goods belonging to neutrals were not. Claims for the award of prize money were usually heard in a prize court, which had to adjudicate the claim and condemn the prize before any distribution of cash or goods could be made to the captors.
Visit and Search is the right of a belligerent warship, under certain conditions, to board a neutral merchant ship in order to verify its true character. The term probably refers to a misunderstanding of the French word visite, which in this context simply means search.
Prize Cases, 67 U.S. 635 (1863), was a case argued before the Supreme Court of the United States in 1862 during the American Civil War. The Supreme Court's decision declared the blockade of the Southern ports ordered by President Abraham Lincoln constitutional. The opinion in the case was written by Supreme Court Justice Robert Cooper Grier.
SMS Seeadler was a three-masted steel-hulled sailing ship. She was one of the last fighting sailing ships to be used in war when she served as a merchant raider with Imperial Germany in World War I. Built as the British-flagged Pass of Balmaha, she was captured by the German submarine SM U-36, and in 1916 converted to a commerce raider. As Seeadler she had a successful raiding career, capturing and sinking 15 ships in 225 days until she was wrecked, in 2 August 1917, in French Polynesia.
In admiralty law prizes are equipment, vehicles, vessels, and cargo captured during armed conflict. The most common use of prize in this sense is the capture of an enemy ship and its cargo as a prize of war. In the past, the capturing force would commonly be allotted a share of the worth of the captured prize. Nations often granted letters of marque that would entitle private parties to capture enemy property, usually ships. Once the ship was secured on friendly territory, it would be made the subject of a prize case: an in rem proceeding in which the court determined the status of the condemned property and the manner in which the property was to be disposed of.
ThePaquete Habana; The Lola, 175 U.S. 677 (1900), was a landmark decision of the United States Supreme Court concerning the applicability and recognition of international law by the United States. The Court held that the capture of fishing vessels as prizes of war violated customary international law, which is integrated with U.S. law and binding as such. Paquete Habana influenced subsequent court decisions that incorporated international law regarding other matters. The case is also notable for citing a wide breadth of historical and international sources, including jurists from around the world and foreign state practices going back centuries.
SMS Möwe was a merchant raider of the Imperial German Navy which operated against Allied shipping during World War I.
SS Black Osprey was a cargo ship for the American Diamond Lines and the British Cairn Line. She was formerly known as SS West Arrow when she was launched for the United States Shipping Board (USSB) during World War I. The ship was inspected by the United States Navy for possible use as USS West Arrow (ID-2585) but was neither taken into the Navy nor ever commissioned under that name.
The Confederate privateers were privately owned ships that were authorized by the government of the Confederate States of America to attack the shipping of the United States. Although the appeal was to profit by capturing merchant vessels and seizing their cargoes, the government was most interested in diverting the efforts of the Union Navy away from the blockade of Southern ports, and perhaps to encourage European intervention in the conflict.
The First League of Armed Neutrality was an alliance of European naval powers between 1780 and 1783 which was intended to protect neutral shipping against the British Royal Navy's wartime policy of unlimited search of neutral shipping for French contraband during the American Revolutionary War and Anglo-French War. According to one estimate, 1 in 5 merchant vessels were searched by the Royal Navy under this policy. By September 1778, at least 59 ships had been taken prize – 8 Danish, 16 Swedish and 35 Dutch, as well as others from Prussia. Protests were enormous by every side involved.

HMS Atalanta was the American letter of marque schooner Siro, launched in 1812, that the British captured in 1814.
