Bolivar's jealousy of San Martin prolonged the war, which might have been brought to a close in a few months, for nearly three years. After the withdrawal of San Martin, Bolivar became Dictator of Peru. On December 9, 1824, was fought the last battle for South American independence. On the little plain of Ayacucho, 11,600 feet above the sea, General Sucre defeated and captured the forces of the viceroy. Upper Peru was organized as a separate republic, with the name of Bolivia. Bolivar had been proclaimed President of Peru for life, but the unpopularity of this measure led him to leave the country in 1826, never to return. That same year he summoned the Congress of Panama, but his plans for the union of South America in one republic failed. San Martin's idea finally triumphed. In 1829 Venezuela separated itself from Colombia and passed a decree of perpetual banishment against Bolivar. In April, 1830, through pressure of public opinion, Bolivar resigned the presidency of Colombia and retired into private life. Congress voted him an annual pension of $30,000. A month later Quito and Guayaquil separated from Colombia and formed the independent state of Ecuador. Even the name Colombia was dropped by the remaining state, and the old name of New Granada adopted. In 1857 the name Colombia was assumed once more. Bolivar died in a small house near Santa Martha, December 17, 1831, having witnessed the failure of his most cherished plans. San Martin had retired to Europe in 1823 with his only child, a daughter named Mercedes. They lived a retired life in Brussels. Once only, in 1828, he returned to his native land, but was received with such denunciation by the press of Buenos Aires that he quickly turned his face towards Europe again. He died at Boulogne, August 17, 1850. Thirty years later the Argentine people had his remains brought back to his native land. In May, 1880, with imposing ceremonies, they were laid to rest in the Cathedral of Buenos Aires.
