Immediately after the exchange of ratifications of the present treaty, all castles, forts, territories, places and possessions, which have been taken or occupied by the forces of the United States during the present war, within the limits of the Mexican republic, as about to be established by the following article, shall be definitely restored to the said republic, together with all the artillery, arms, apparatus of war, munitions and other public property, which were in the said castles and forts when captured, and which shall remain there at the time when this treaty shall be duly ratified by the government of the Mexican republic. To this end, immediately upon the signature of this treaty, orders shall be dispatched to the American officers commanding such castles and forts, securing against the removal or destruction of any such artillery, arms, apparatus of war, munitions or other public property.

The final evacuation of the territory of the Mexican republic, by the forces of the United States, shall be completed in three months from the said exchange of ratifications, or sooner if possible: the Mexican government hereby engaging, as in the foregoing article, to use all means in its power for facilitating such evacuation, and rendering it convenient to the troops, and for promoting a good understanding between them and the inhabitants.

If, however, the ratification of this treaty by both parties should not take place in time to allow the embarkation of the troops of the United States to be completed before the commencement of the sickly season, at the Mexican ports on the gulf of Mexico, in such case a friendly arrangement shall be entered into between the general-in-chief of the said troops and the Mexican government, whereby healthy and otherwise suitable places, at a distance from the ports not exceeding thirty leagues, shall be designated for the residence of such troops as may not yet have embarked, until the return of the healthy season. And the space of time here referred to as comprehending the sickly season, shall be understood to extend from the first day of May to the first day of November.

All prisoners of war taken on either side, on land or on sea, shall be restored as soon as practicable after the exchange of ratifications of this treaty. It is also agreed that if any Mexicans should now be held as captives by any savage tribe within the limits of the United States, as about to be established by the following article, the government of the said United States will exact the release of such captives, and cause them to be restored to their country.
