Inasmuch as the King of the Franks, as has been observed, has sent forth to France some of his nobles, with whom the King of England has been united in league, to the end that, by God's grace, they might resist the assaults of the pagans; and inasmuch as that same King of England has likewise been associated with the King of France in other treaties, it is to be understood that there is to be a reciprocal assistance and fellowship between them. For if the King of England be involved in war with any person, so that he shall need the succor of the King of France, then shall the King of France send aid to the King of England; and if, on the other hand, the King of France be involved in war, then shall the King of England send him aid. So also shall they be friends to friends and enemies to enemies. Nor is this to be understood to apply only to the King of England and the King of France, but to all their vassals and dependants, and indeed to all the kingdom of the French, and to all the kingdom of the English.

If either of these Kings shall have occasion to send a messenger to the other, he shall, upon his arrival, receive all due respect, and be furnished with all things needful for his journey, and shall be sent back with all speed. If the King of England shall have any quarrel with the King of France, or the King of France with the King of England, it shall be judged by the counsel of all their barons. If any dispute arise betwixt the English and the French, it shall be settled by the judgment of the Kings themselves, or by their delegates. It shall be lawful for either King to go into the territory of the other, with such attendants as he shall deem sufficient, and to abide there for a period not exceeding three months, unless indeed he shall be invited to stay longer by the King of the country. In like manner, any man of the kingdom of England may go into the kingdom of France, and any man of the kingdom of France may go into the kingdom of England, and dwell there for a space of one year, without let or hindrance, provided that he shall be of good behaviour, and shall not commit any offence against the laws of the land. But if he shall be found guilty of any crime, he shall be judged and punished according to the laws of the country wherein he dwells. If either King shall deem it expedient to make war on any country, he shall first consult with the other, and if they shall be agreed, they shall make war together. But if they shall not be agreed, then neither shall make war without the consent of the other. If any man of the kingdom of England shall be taken captive in the kingdom of France, or any man of the kingdom of France shall be taken captive in the kingdom of England, the King of the country wherein he is taken shall be bound to ransom him, or to see that he be ransomed, within the space of one year. And if he shall fail to do so, he shall be bound to pay to him that hath taken him captive, the sum of one hundred pounds sterling.
