Baúl along with Julio César Monagas, in January 1860. In El Baúl, generals Sotillo and Julio César Monagas met with general Juan Crisóstomo Falcón and the Federal armies of the West. On 17 February 1860, he participated in the battle of Coplé, taking control simultaneously of the Eastern column, when general Falcón dissolved a division of the Federal Army as a consequence of the defeat suffered in that battle against general León de Febres Cordero. Earlier that month, on 2 February 1860, general Sotillo's son, José Antonio Sotillo, died under enemy fire from centralist colonel José López Mercado at El Lecherito. As a consequence of this, his other son, Miguel Sotillo, decided to execute all their prisoners in retaliation. However, Sotillo prevented his son from carrying out this scheme, an outstanding gesture that has always been recognized by Venezuelan historians. Later, when arriving in eastern Venezuela, he established a guerrilla operation, from March to May 1860. Unfortunately, he was defeated on three occasions, the first in El Lecherito in July 1860; a second one in Aragua, on 16 August; and the last one in Santa Ana, on 21 August 1860. After these defeats, on 29 March 1860, Sotillo reunited his forces with those of general Julio César Monagas, son of his friend general José Gregorio Monagas. Months thereafter, Sotillo and Monagas fought together in the territory of La Mesa de Guanipa in April 1861. That same year, in October, he signed a short truce, well known under the name of the Treaty of Santa Ana, with general José Maria Zamora's forces. However, Sotillo took up arms to fight in the battle of Las Chaguaramas, on 3 April 1862, where he was once more defeated and his son Miguel was mortally wounded. Julio César Monagas also died in May that same year as a consequence of his injuries from the Battle of Cureña (11 April 1861). In March 1863 he continued his guerrilla activities towards the Eastern part of the province of Guárico and, in August, towards Guayana. After the military triumph of the Federación on 8 April 1862, Sotillo retired to Barcelona where he received a modest allowance for his military services. Last years On 4 March 1868, general Sotillo took up arms for the last time against the government of general Juan Crisóstomo Falcón, during the Blue Revolution. Again, he was called on by his former commander and compadre
