February 06, 1778
The Most Christian King and the United States of North America, to wit: New Hampshire, Massachusetts Bay, Rhodes Island, Connecticut, New York, New Jersey, Pennsylvania, Delaware, Maryland, Virginia, North Carolina, South Carolina, and Georgia, having this day concluded a treaty of amity and commerce, for the reciprocal advantage of their subjects and citizens, have thought it necessary to take into consideration the means of strengthening those engagements, and of rendering them useful to the safety and tranquility of the two parties; particularly in case Great Britain, in resentment of that connection and of the good correspondence which is the object of the said treaty, should break the peace with France, either by direct hostilities, or by hindering her commerce and navigation in a manner contrary to the rights of nations, and the peace subsisting between the two Crowns. And His Majesty and the said United States, having resolved in that case to join their councils and efforts against the enterprises of their common enemy, the respective Plenipotentiaries impowered to concert the clauses and conditions proper to fulfill the said intentions, have, after the most mature deliberation, concluded and determined on the following articles:
If war should break out between France and Great Britain during the continuance of the present war between the United States and England, His Majesty the said United States shall make it a common cause and aid each other mutually with their good offices, their councils and their forces, according to the exigence of conjunctures, as becomes good and faithful allies.
The essential and direct end of the present defensive alliance is to maintain effectually the liberty, sovereignty, and independance absolute and unlimited, of the said United States, as well in matters of government as of commerce.
The two contracting parties shall each on its own part, and in the manner it may judge most proper, make all the efforts in its power against their common enemy, in order to attain the end proposed.
The contracting parties agree that in case either of them should form any particular enterprise in which the concurrence of the other may be desired, the party whose concurrence is desired, shall readily, and with good faith, join to act in concert for that purpose, as far as circumstances and its own particular situation will permit; and in that case, they shall regulate, by a particular convention, the quality and kind of succour to be furnished, and the time and manner of its being brought into action, as well as the advantages which are to be its compensation.
If the United States should think fit to attempt the reduction of the British power, remaining in the northern parts of America, or the islands of Bermudas, those countries or islands, in case of success, shall be confederated with or dependant upon the said United States.
The Most Christian King renounces forever the possession of the islands of Bermudas, as well as of any part of the continent of North America, which before the treaty of Paris in 1763, or in virtue of that treaty, were acknowledged to belong to the Crown of Great Britain, or to the United States, heretofore called British Colonies, or which are at this time, or have lately been under the power of the King and Crown of Great Britain.
If His Most Christian Majesty shall think proper to attack any of the islands situated in the Gulph of Mexico, or near that Gulph, which are at present under the power of Great Britain, all the said isles, in case of success, shall appertain to the Crown of France.
Neither of the two parties shall conclude either truce or peace with Great Britain without the formal consent of the other first obtained; and they mutually engage not to lay down their arms until the independence of the United States shall have been formally or tacitly assured by the treaty or treaties that shall terminate the war.
The contracting parties declare, that being resolved to fulfill each on its own part the clauses and conditions of the present treaty of alliance, according to its own power and circumstances, there shall be no after claim of compensation on one side or the other, whatever may be the event of the war.
The Most Christian King and the United States agree to invite or admit other powers who may have received injuries from England, to make common cause with them, and to accede to the present alliance, under such conditions as shall be freely agreed to and settled between all the parties.
The two parties guarantee mutually from the present time and forever against all other powers, to wit: The United States to His Most Christian Majesty, the present possessions of the Crown of France in America, as well as those which it may acquire by the future treaty of peace: And His Most Christian Majesty guarantees on his part to the United States their liberty, sovereignty and independence, absolute and unlimited, as well in matters of government as commerce, and also their possessions, and the additions or conquests that their confederation may obtain during the war, from any of the dominions now, or heretofore possessed by Great Britain in North America, conformable to the 5th and 6th articles above written, the whole as their possessions shall be fixed and assured to the said States, at the moment of the cessation of their present war with England.
In order to fix more precisely the sense and application of the preceding article, the contracting parties declare, that in case of a rupture between France and England the reciprocal guarantee declared in the said article shall have its full force and effect the moment such war shall break out; and if such rupture shall not take place, the mutual obligations of the said guarantee shall not commence until the moment of the cessation of the present war between the United States and England shall have ascertained their possessions.
The present treaty shall be ratified on both sides, and the ratifications shall be exchanged in the space of six months, or sooner if possible…
