Nearly two hundred years later, in 1243, King Henry III. issued regular patents, or commissions, to certain persons, seamen by profession, "to annoy the king's enemies by sea or land wheresoever they are able," and enjoined all his faithful subjects to refrain from injuring or hindering them in this business; the condition being that half the plunder was to be given to the king, "in his wardrobe"—that is, his private purse—and it is quite probable that both the king and the recipients of his commission made a nice little profit out of it.

This is a genuine instance of what was known later as privateering; and it will be noticed that the "king's enemies" are specified as the only persons against whom the commission holds good; in other words, such a commission can have no significance, nor indeed can it be issued, in time of peace or against any friendly Power. This is an essential characteristic of privateering: it can only be carried on when a state of war exists, and the fitting out of a privateer to attack the subjects of any sovereign would in itself be an act of war.

Now let us see what is meant by a letter of marque; there is a good instance on record at the end of the thirteenth century, in the reign of Edward I.

One Bernard D'Ongressill, a merchant of Bayonne—at that time a portion of the realm of the King of England—in the year 1295, was making a peaceful, and, as he hoped, a profitable voyage from Barbary to England, in his ship the St. Mary, with a cargo of almonds, raisins, and figs; unfortunately he encountered heavy weather, and was compelled to run into Lagos—a small sea-port at the south-west corner of Portugal which affords secure shelter from westerly gales—and, while he was waiting for the weather to moderate, there came from Lisbon some armed men, who robbed D'Ongressill of the ship, cargo, and the private property of himself and his crew, and took the whole of their spoil to Lisbon. The King of Portugal very unscrupulously appropriated one-tenth of the plunder, the remainder being divided among the robbers.

The unhappy victim at once applied for redress to the king's representative, Sir John of Brittany, Lieutenant of Gascony, representing that he had lost some £700, and requesting that he might be granted letters of marque against the Portuguese, to take whatever he could from them, until he had made up his loss. This was conceded, and authority bestowed to "seize by right of marque,[1] retain, and appropriate the people of Portugal, and especially those of Lisbon and their goods, wheresoever they might be found," for five years, or until he had obtained restitution. This was dated in June: but the king's ratification was necessary, and this caused some delay, as Edward was at that time shut up in a Welsh castle; however, he was able in October to confirm the licence; but he added the proviso that if D'Ongressill took more than £700 worth from the Portuguese, he would be held answerable for the balance.

This is an excellent example of the form and import of a letter of marque; and it will be noticed that England was not at war with Portugal, nor did the issue of this letter of marque constitute an act of war; it was, in fact, a licence to a private individual to recover by force from the subjects of another sovereign the goods of which he had been despoiled; the practice dates back, certainly, to the early part of the twelfth century, and probably further; and it was in use in England until the time of Charles II., or later. The one condition, not mentioned in the case of D'Ongressill, was that letters of marque should not be granted until every effort had been made to obtain a peaceful settlement; representations may, however, have been made to the King of Portugal; but if, as stated by D'Ongressill, he had pocketed a tithe of the spoil, one can imagine that there might be some difficulty in the matter; the possession of one-tenth would naturally appear, in the eyes of his Majesty of Portugal, to constitute nine points of the law!

The application of the term letter of marque to vessels which were in reality privateers has caused a good deal of confusion; some naval historians of great repute have fallen into error over it, one of them, for instance, alluding to the commissions granted by Henry III., in 1243, as the "first recorded instance of the issue of letters of marque"; rather an inexcusable mistake, from which the present reader is happily exempt.

While guarding, in this explanation, against such confusion of terms, we must, notwithstanding, accept the ultimate adoption of it; and so we shall find included among our privateers and their commanders some who were quite improperly described as letters of marque, and one, at least, who may correctly be thus designated, but who, as an interesting example of a sort of privateering at an early period, appears to deserve mention.

The bearer of a letter of marque—or "mart," as it was constantly termed by writers and others of that class of persons who never will take the trouble to pronounce an unusual word properly—came to be adopted as the type of a sort of swashbuckler—a reckless, bullying individual, armed with doubtful credentials in the pursuit of some more or less discreditable object: allusion of this nature is made more than once by Beaumont and Fletcher in their plays, as well as by other writers.

The immense value of a fleet of privateers, more especially to a country opposed to another possessing a large mercantile marine, is obvious, and their use developed very rapidly.
