As with most residents of Venezuela at the time, Boves was supportive of the juntas established in Venezuela in 1810, after news arrived that the reigning Supreme Central Junta in Spain had dissolved itself because of French advances in southern Spain. His activities against the Republic only began after Domingo de Monteverde began his incursions into central Venezuela. He joined Monteverde's forces when they took over Calabozo in May 1812 and was named commander of Calabozo in January 1813. He participated in the unsuccessful attempts to stop Santiago Mariño's invasion of eastern Venezuela, and after the royalist government collapsed, he was granted temporary permission to act at his own discretion by his superior, Field Marshal Juan Manuel Cajigal.
From this point on, he never recognized any superior authority. Making use of his knowledge of the llanos he amassed a large army of llaneros, most of whom were pardo (mixed-race), and dominated the south of the country for the next two years until his death. He lived among, and exposed himself to the same risks in battle as, his soldiers, thereby gaining their extreme loyalty. Although nominally royalist, Boves turned the old colonial order on its head. He ignored Cajigal, who by 1814 was captain general, even when they were campaigning together, and appointed political and military commanders of his own choosing. Further still from his mind was the Spanish Constitution of 1812, which should have been in effect in Venezuela during this time. Most striking for his contemporaries, though, was that he allowed his llanero soldiers to engage in a class and race war against the landed and urban classes of Venezuela, fulfilling the latters' fear, since 1810, that the revolution could devolve into another Haitian Revolution. (Compare Hidalgo's assault on Guanajuato.) Boves's army became feared for its liberal use of pillage and summary executions, which became notorious even in this period when such actions were common on both sides of the conflict. (See Simón Bolívar's "Decree of War to the Death".)''
Throughout the second half of 1813, Boves and his army assailed the Second Republic in a series of battles, but without any clear gains until the Battle of La Puerta on June 15, 1814. He captured Valencia and Caracas the following month. He died at the age of 32 in the Battle of Urica, which his troops nevertheless won. Command of his troops passed on to Tomás Morales. His actions laid the ground work for Pablo Morillo's expeditionary force to easily occupy Venezuela and to spend its massive resources in neighboring New Granada. Royalists would continue to control Venezuela until 1821.
That fabulous Asturian warrior, who between 1813 and 1814 was champion of the anti-republic, feverish destroyer of the colonial order and the first caudillo of democracy in Venezuela.
The novel is being adapted in 2008 into film by Venezuelan director Luis Alberto Lamata, director of Jericó (1991).
