The firm and explicit attitude of the two rulers put an end to France's last illusions. The only thing to subdue Haiti would be the use of greater force than it would be possible for her to cope with. Once more the Haitians prepared themselves for the attack which seemed to be imminent.

Notwithstanding the anxiety caused by such a contingency, Haiti did not forget what she considered her duty toward those who were fighting to free themselves from European domination. She gave a hearty welcome to Simon Bolivar, Commodore Aury, and the many Venezuelan families whom the successes of the Spaniards had compelled to leave their country. At the end of December 1815, Bolivar arrived at Cayes, in which port were anchored, on January 6, 1816, ten men-of-war commanded by Commodore Aury, who had been forced to evacuate Carthagena. The embarrassed circumstances in which the Republic found itself did not prevent Pétion from extending all the help he could to the sailors and the Venezuelan families, who, owing to their hasty flight, were in the greatest state of indigence. He was most kind to Bolivar, requesting only in return for the unselfish assistance given to the latter's cause, that slavery be abolished. Bolivar endeavored to be true to his word.



Bolivar promised to proclaim general freedom in Venezuela province and all other provinces which he should succeed in winning over to the cause of independence. He received from the President of Haiti 4,000 rifles, powder, cartridges, all kinds of provisions, even a printing-press. Pétion did not content himself with furnishing these articles; he was peace-maker between Bolivar and his two companions, General Bermudes and Commodore Aury, who had quarreled, thus dispelling for the time being the misunderstanding which was about to set them at variance. Haitians were authorized to join in the expedition. In the following letter written on the 8th of February, Bolivar expressed his intense gratitude to Pétion :
Mr. PRESIDENT: I am overwhelmed with your favors. In everything you are magnanimous and kind. We have almost completed our preparations and in a fortnight we may perhaps be ready to start; I am only awaiting your last favors. Through Mr. Inginac, your worthy Secretary, I take the liberty to make a new request. In my proclamation to the inhabitants of Venezuela and in the decrees I have to issue concerning the freedom of the slaves, I do not know if I am allowed to express the feelings of my heart toward Your Excellency and to leave to posterity an everlasting token of your philanthropy. I do not know, I say, if I must declare that you are the author of our liberty. I beg Your Excellency to let me know his will on the matter.
Pétion refused to be designated as the author of the independence of Venezuela and made the following answer to Bolivar:
PORT-AU-PRINCE.
February 18, 1816, the 13th year of the Independence.
GENERAL: Your kind letter of the 8th instant reached me yesterday. You know my regard for the cause you are defending and for yourself; you must then be convinced how great is my desire to see freedom granted to all those who are still under the yoke of slavery; but out of deference for a power which has not yet openly declared itself an enemy of the Republic, I am compelled to ask you not to mention my name in any of your documents; and for this purpose I reckon on the sentiments which characterize you.
After leaving Cayes on the 10th of April, 1816, Bolivar landed at Carupano on May 31. Defeated on the 10th of July by the Spanish General Morales, he fled again to Haiti. Pétion once more gave him his sympathy and assistance, furnishing him with large supplies of arms, ammunition, etc. On the 26th of December, 1816, Bolivar left Haiti and this time succeeded in ridding his country of Spanish domination. He expressed his gratitude once more in the following letter which he wrote before embarking, to General Marion, Commandant of the arrondissement of Cayes:
"PORT-AU-PRINCE, December 4, 1816.
GENERAL.: On the point of starting with a view to return to my country and strengthen its independence, I feel that it would be ungrateful of me were I to miss this opportunity of thanking you for all your kindness to my countrymen. If men are bound by the favors they have received, be sure, General, that my countrymen and myself will forever love the Haitian people and the worthy rulers who make them happy."
He freed his own slaves numbering about 1,500 and, on the 6th of July, 1816, granted general freedom. But such a measure met with the strongest opposition. In 1821 a gradual freedom was proclaimed; it was only in 1854 that the last slaves were freed owing to the influence of General Monagas, the President of the Republic of Venezuela.
And a few years later (1826) Bolivar refrained from inviting Haiti to the Congress of Panama which he himself organized!
Pétion was successively reelected President on the 9th of March, 1811, and on the 9th of March, 1815.
On the 2d of June, 1816, the Constitution of 1806 was modified. The authority was divided between the Executive, the Legislative and the Judiciary Powers. A Supreme Court (Tribunal de Cassation) was created; and henceforth the Legislative body was to consist of a Senate and a House of Commons. The President of Haiti, elected for life by the Senate, had the right to appoint all the civil and military functionaries and also to direct the exterior relations.
In pursuance of this Constitution, Pétion was elected President for life on the 9th of October, 1816. But he did not long survive this last election. On the 22d of March he had an attack of fever, to which he succumbed on the 29th of March, 1818, in spite of all the efforts that were made to restore him to health.
