In February, 1819, the second Congress of Venezuela convened at Angostura. The Dictator resigned, but was unanimously elected President and given absolute power in all provinces which were the actual theater of war. The army was reorganized by the accession of foreign troops, in particular the British legion, consisting of 2,000 well equipped men, which achieved much of the success of the next year. Bolivar now conceived the idea of crossing the Cordillera and reconquering New Granada. General Paez was to attract the attention of Morillo on the plains in front, and a demonstration was to be made on the coast near Caracas, while Bolivar marched to the west. This movement changed the whole face of affairs and had a similar effect to the passage of the Andes by San Martin. New Granada was won by the battle of Boyaca, August 7, 1819. Morillo was now isolated in Venezuela. In December, 1819, a congress of delegates from Venezuela and New Granada met and decreed the union of the two provinces in the Republic of Colombia. Bolivar was named provisional President. An armistice was signed by Bolivar and Morillo in November, 1820, which gave the Patriots breathing time. The Spanish troops remaining in Venezuela were defeated by Bolivar in the battle of Carabobo, June 23, 1821. Only a few fortresses on the coast were still held by the Spaniards. Bolivar entered Caracas once more in triumph and tendered his resignation, an act always considered by him necessary for giving the proper dramatic setting to such occasions. Congress took no notice of it, but drew up a constitution providing for a limited presidential term of four years. The Liberator, "as he feared," was elected President. He repeated his resignation, but added that he would yield if Congress persisted. Congress did persist.
