Bolívar: American Liberator by Marie Arana:
By August, he was traveling the vertiginous route to La Paz, the capital of Upper Peru. The ride was grueling, but conspicuously free of enemies. The last of the Spanish generals, the renegade Olañeta, stubbornly prowling those mountains for two years, had died months before, mortally wounded in battle. Word had it that he had met his end at the hands of his own men; indeed, he had been the only victim in a fleeting skirmish against Sucre’s army. Seeing Olañeta fall from his horse, his soldiers—a fraction of his original force—rushed to surrender. It was hardly surprising, as royalist defections after the Battle of Ayacucho had been epidemic; everyone wanted to be on Sucre’s side. The grand marshal proceeded to carry out his assignment in Upper Peru admirably.
Sucre met Bolívar on the shores of Lake Titicaca not far from where the old viceroyalty of Peru ended and the old viceroyalty of Buenos Aires began. There, at long last, Bolívar embraced Sucre and thanked him for his many momentous achievements: the victory at Ayacucho, the suppression of Olañeta, the successful occupation of La Paz and Potosí. It had been almost a year since they had seen each other.
