Ricans joined the ranks of the United States military armed forces, however since Puerto Ricans were Spanish subjects they were inscribed as Spaniards. The 1860 census of New Haven, Connecticut, shows there were 10 Puerto Ricans living there. Among them was Augusto Rodriguez who joined the 15th Connecticut Regiment (a.k.a. Lyon Regiment) in 1862. During the Civil War, Rodriguez, who reached the rank of lieutenant, served in the defenses of Washington, D.C. He also led his men in the Battles of Fredericksburg and Wyse Fork. The regiment was mustered out on June 27, 1865, and he was discharged in New Haven on July 12, 1865. Slave revolts Slavery was abolished in Puerto Rico in 1873, but the wealth amassed by many landowners in Puerto Rico through a plantation economy was generated by the exploitation of slaves. According to one source, this reliance on slavery "generated its antithesis—disobedience, uprisings and flights." In Puerto Rico, there were many minor slave revolts in which the slaves clashed with the military establishment. In July 1821, Marcos Xiorro, a bozal slave, planned and organized a conspiracy against the slave masters and the colonial government of Puerto Rico. According to his plot, which was to be carried out on July 27, during the festival celebrations for Santiago (St. James), several slaves were to escape from various plantations in Bayamón, which included the haciendas of Angus McBean, C. Kortnight, Miguel Andino and Fernando Fernández. They were then to proceed to the sugarcane fields of Miguel Figueres, and retrieve cutlasses and swords which were hidden in those fields. Xiorro, together with a slave from the McBean plantation named Mario and another slave named Narciso, would lead the slaves of Bayamón and Toa Baja and capture the city of Bayamón. They would then burn the city and kill those who were not black. After this, they would all unite with slaves from the adjoining towns of Río Piedras, Guaynabo and Palo Seco. With this critical mass of slaves, all armed and emboldened from a series of quick victories, they would then invade the capital city of San Juan, where they would declare Xiorro as their king. Unfortunately for the slave conspirators, the plot was divulged by a fellow slave to the authorities. In response, the mayor of Bayamón mobilized 500 soldiers. The ringleaders and followers of the conspiracy were captured immediately. A total of 61 slaves were imprisoned in
