In the "days of fighting sail, a letter of marque and reprisal was a government license authorizing a person (known as a "privateer) to attack and capture enemy vessels and bring them before "admiralty courts for condemnation and sale. Cruising for prizes with a letter of marque was considered an honorable calling combining patriotism and profit, in contrast to unlicensed "piracy, which was universally reviled. In addition to the term lettre de marque, the "French sometimes used the term lettre de course for their letters of marque. "Letter of marque" was sometimes used to describe the vessel used: a "letter of marque" generally refers to a lumbering square-rigged cargo carrier that might pick up a prize if the opportunity arose. A "privateer" was a fast and weatherly fore-and-aft-rigged vessel heavily armed and heavily crewed, intended exclusively for fighting.
A "letter of marque and reprisal" would include permission to cross an international border to effect a reprisal (take some action against an attack or injury) authorized by an issuing jurisdiction to conduct reprisal operations outside its borders.
Old English mearc, from Germanic *mark- ‘boundary; boundary marker’, from Proto-Indo-European *merǵ- ‘boundary, border’.
French, from Provençal marca, from marcar ‘seize as a pledge‘
According to the "Oxford English Dictionary, the first recorded use of "letters of marque and reprisal" was in an English statute in 1354 during the reign of "Edward III. The phrase referred to "a licen[c]e granted by a sovereign to a subject, authorizing him to make reprisals on the subjects of a hostile state for injuries alleged to have been done to him by the enemy's army."
During the "Middle Ages, armed private vessels enjoying their sovereign's tacit consent, if not always an explicit formal commission, regularly raided shipping of other nations, as in the case of "Francis Drake's attacks on Spanish shipping, of which "Elizabeth I (despite protestations of innocence) took a share. "Grotius's 1604 seminal work on international law, De Iure Praedae (Of The Law of Prize and Booty), was an advocate's brief defending Dutch raids on Spanish and Portuguese shipping.
"King Henry III of England first issued what later became known as privateering commissions in 1243. These early licences were granted to specific individuals to seize the king’s enemies at sea in return for splitting the proceeds between the privateers and the crown.
The letter of marque and reprisal first arose in 1295, 50 years after wartime privateer licenses were first issued. According to Grotius, letters of marque and reprisal were akin to a "private war", a concept alien to modern sensibilities but related to an age when the ocean was lawless and all merchant vessels sailed armed for self-defense. A reprisal involved seeking the sovereign's permission to exact private retribution against some foreign prince or subject. The earliest instance of a licensed reprisal recorded in England was in the year 1295 under the reign of Edward I. The notion of reprisal, and behind it that just war involved avenging a wrong, clung to the letter of marque until 1620 in England, in that to apply for one a shipowner had to submit to the Admiralty Court an estimate of actual losses.
Licensing privateers during wartime became widespread in Europe by the 16th Century, when most countries began to enact laws regulating the granting of letters of marque and reprisal. Business could be very profitable, during the eight years of the "American Revolutionary War ships from the tiny island of "Guernsey carrying letter of marque captured French and American vessels to the value of £900,000 and continued to operate during the "Napoleonic Wars. (Of course, profitable cruises paid for unprofitable ones, including cruises in which the enemy captured the privateer before it had captured anything.)
Although privateering commissions and letters of marque were originally distinct legal concepts, such distinctions became purely technical by the eighteenth century. The United States Constitution, for instance, states that "The Congress shall have Power To ... grant Letters of marque and reprisal ...”, without separately addressing privateer commissions.
During the "American War of Independence, "Napoleonic Wars, and the "War of 1812, it was common to distinguish verbally between privateers (also known as private ships of war) on the one hand, and armed merchantmen, which were referred to as "letters of marque", on the other, though both received the same commission. The "Sir John Sherbrooke (Halifax) was a privateer; the "Sir John Sherbrooke (Saint John) was an armed merchantman. The "East India Company arranged for letters of marque for its "East Indiamen such as the "Lord Nelson, not so that they could carry cannons to fend off warships, privateers, and pirates on their voyages to India and China—that they could do without permission—but so that, should they have the opportunity to take a prize, they could do so without being guilty of piracy. Similarly, the "Earl of Mornington, an East India Company "packet ship of only six guns, too carried a letter of marque.
In July 1793, the East Indiamen "Royal Charlotte, Triton, and "Warley participated in the capture of "Pondichéry by maintaining a blockade of the port. Afterwards, as they were on their way to China, the same three East Indiamen participated in an action in the "Straits of Malacca. They came upon a French "frigate, with some six or seven of her prizes, replenishing her water casks ashore. The three British vessels immediately gave chase. The frigate fled towards the "Sunda Strait. The Indiamen were able to catch up with a number of the prizes, and, after a few cannon shots, were able to retake them. Had they not carried letters of marque, such behaviour might well have qualified as piracy. Similarly, on 10 November 1800 the East Indiaman "Phoenix captured the French privateer General Malartic, under "Jean-Marie Dutertre, an action made legal by a letter of marque. Additionally, vessels with a letter of marque were exempt from having to sail in convoy, and nominally their crew members were exempt, during a voyage, from "impressment.
The procedure for issuing letters of marque and the issuing authority varied by time and circumstance. In colonial America, for instance, colonial governors issued them in the name of the king. During the American Revolution, first the state legislatures, then both the states and the Continental Congress, then, after ratification of the "Constitution, Congress authorized and the President signed letters of marque. A shipowner would send in an application stating the name, description, tonnage, and force (armaments) of the vessel, the name and residence of the owner, and the intended number of crew, and tendered a bond promising strict observance of the country's laws and treaties and of international laws and customs. The commission was granted to the vessel, not to its captain, often for a limited time or specified area, and stated the enemy upon whom attacks were permitted. For instance, during the "Second Barbary War President James Madison authorized the Salem, Mass., brig Grand Turk to cruise against "Algerine vessels, public or private, goods and effects, of or belonging to the "Dey of Algiers". (Interestingly, this particular commission was never put to use, as it was issued the same day the treaty was signed ending the U.S. involvement in the war—July 3, 1815.)
In England in the 18th century, a Letter of Marque was issued by the High Court of Admiralty of England. It was normal for the proposed privateer to pay a deposit or bond, possibly £1,500 (current value £150,000) as surety for good behaviour. The details of the ship, including tonnage, crew and weapons were recorded. The ownership of these ships was often split into ⅛ shares. Prizes were assessed and valued with profits split in pre agreed proportions between the government, the owners and the captain and crew.:75
A letter of marque and reprisal in effect converted a private merchant vessel into a naval auxiliary. A commissioned privateer enjoyed the protection and was subject to the obligations of the laws of war. If captured, the crew was entitled to honorable treatment as prisoners of war, while without the licence they were deemed mere pirates "at war with all the world," criminals who were properly hanged.
For this reason, enterprising maritime raiders commonly took advantage of ""flag of convenience" letters of marque, shopping for cooperative governments to license and legitimize their depredations. French/Irishman Captain Luke Ryan and his lieutenants in just over two years commanded six vessels under the flags of three different nations and on opposite sides in the same war. Likewise the notorious Lafitte brothers in New Orleans cruised under letters of marque secured by bribery from corrupt officials of tenuous Central American governments, to cloak plunder with a thin veil of legality.
The letter of marque by its terms required privateers to bring captured vessels and their cargoes before "admiralty courts of their own or allied countries for condemnation. Applying the rules and customs of "prize law, the courts decided whether the letter of marque was valid and current, and whether the captured vessel or its cargo in fact belonged to the enemy (not always easy, when flying false flags was common practice), and if so the prize and its cargo were "condemned," to be sold at auction with the proceeds divided among the privateer's owner and crew. A prize court's formal condemnation was required to transfer title; otherwise the vessel's previous owners might well reclaim her on her next voyage, and seek damages for the confiscated cargo.
Often questions arose as to the legitimacy of the letter of marque in the case of divided sovereignty during civil wars. An English court, for instance, refused to recognize the letters of marque issued by rebellious Ireland under "James II, and hanged eight privateer captains as pirates. Seventy-nine years later during the American Civil War, the Union charged officers and crew of the "Confederate privateer Savannah with piracy, calling their letter of marque invalid since the Union refused to acknowledge the breakaway Confederacy as a sovereign nation. The case resulted in a "hung jury, and after Confederate President "Jefferson Davis threatened to retaliate by hanging one Union officer for each executed Confederate privateer, the Union relented and thereafter treated Confederate privateersmen honorably as prisoners of war.
Privateers were also required by the terms of their letters of marque to obey the laws of war, honour treaty obligations (avoid attacking neutrals), and in particular to treat captives as courteously and kindly as they safely could. If they failed to live up to their obligations, the Admiralty courts could — and did — revoke the letter of marque, refuse to award prize money, forfeit bonds, or even award "tort (personal injury) damages against the privateer's officers and crew.
Nations often agreed by treaty to forgo privateering, as England and France repeatedly did starting with the diplomatic overtures of "Edward III in 1324; privateering nonetheless recurred in every war between them for the next 500 years.
"Benjamin Franklin had attempted to persuade the French to lead by example and stop issuing letters of marque to their corsairs, but the effort foundered when war loomed with Britain once again. The "French Convention did forbid the practice, but it was reinstated after the "Thermidorian Reaction, in August 1795; on 26 September 1797, the Ministry of the Navy was authorized to sell small ships to private parties for this purpose.
Finally, after the Congress of Paris at the end of the "Crimean War, seven European nations signed the "Paris Declaration of 1856 renouncing privateering, and forty-five more eventually joined them, which in effect abolished privateering worldwide. The United States was not a signatory to that declaration. Despite the attempt to end privateering around the world, nations continued issuing letters of marque. In 1879 at the beginning of the "War of the Pacific, "Bolivia issued letters of marque to any vessels willing to fight for them. At the time Bolivia was under threat from Chile's fleet but had no navy.
In December 1941 and the first months of 1942, Goodyear commercial "L class blimp Resolute operating out of "Moffett Field in Sunnyvale, California, flew anti-submarine patrols. As the civilian crew was armed with a rifle, many thought this made the ship a privateer, and that she and sister commercial blimps were operated under letter of marque until the Navy took over operation. Without congressional authorization, the Navy would not have been able to legally issue any letters of marque.
"Article 1 of the "United States Constitution lists issuing letters of marque and reprisal in Section 8 as one of the "enumerated powers of "Congress, alongside the power to tax and to declare War. However, since the American Civil War, the United States as a matter of policy has consistently followed the terms of the "1856 Paris Declaration forbidding the practice. The United States has not legally commissioned any privateers since 1815, although the status of submarine-hunting Goodyear airships in the early days of "World War II created significant confusion. Various accounts refer to airships Resolute and Volunteer as operating under a "privateer status", but Congress never authorized a commission, nor did the President sign one.
The issue of marque and reprisal was raised before Congress after the "September 11 attacks and again on July 21, 2007, by Congressman "Ron Paul. The attacks were defined as acts of "air piracy" and the Marque and Reprisal Act of 2001 was introduced, which would have granted the president the authority to use letters of marque and reprisal against the specific terrorists, instead of warring against a foreign state. The terrorists were compared to pirates in that they are difficult to fight by traditional military means. Paul on April 15, 2009, also advocated the use of letters of marque to address the issue of "Somali pirates operating in the Gulf of Aden. However, the bills Paul introduced were not enacted into law.
Former "New Mexico Governor and 2012/2016 "Libertarian Presidential candidate "Gary Johnson quipped in his "reddit AMA that letters of marque and reprisal would be an effective way to apprehend "Lord's Resistance Army leader "Joseph Kony instead of using US troops.
