and Justiniano Posse. With the fall or Fragueiro in 1860, victim of his double play of support and opposition to the federal government, Posse took control of the province, and tilted the government to a decided support of the policies of Buenos Aires. Even after the federal intervention of President Santiago Derqui, his group reached power with Posse, after the Battle of Pavón and the short tenure of Marcos Paz. Ferreyra did not show himself in the forefront of local politics until Posse's resignation, in June 1863, victim of the confrontations between federals and Unitarians in the province. Córdoba's federalism was not finally defeated until the end of the 1860s; and then it did not disappear, but joined some other minority factions to form the National Autonomist Party, which would govern without opposition until 1916. After Posse's resignation, the legislature elected his minister Benigno Ocampo in his place, which overtook Ferreyra by one vote. Second term as governor After a short while Ocampo also resigned, and Ferreyra was elected governor for the second time, counting with the support of the federals, which only asked in return, distancing from Posse. The latter made enemies with the governor, reelected temporarily in March. In February Ferreyra was victorious in stopping a federal revolution, and had pardoned the people responsible, with he hoped to obtain their political support. In March 1865 there was a unitarian revolution instigated by Posse. It was quickly defeated and Posse was arrested and an officer who was not certain of final victory had him shot. As the opposition, and also the government accused Ferreyra of having caused Posse's death, he requested the visit of the federal Interior Minister, Guillermo Rawson, to testify for his innocence. Rawson instead asked for Ferreyra's resignation, not for considering guilty, but for thinking him a strong ally of president Mitre. Ferreyra refused to resign. Soon after the Paraguayan War started and he sent several battalions to the front. While the unitarians had enlisted voluntarily, the opposition to the war by the federalists caused several units to rebel along the way to the front. The battalion that protected the government in the provincial capital also mutinied and refused to go to war. It was then dissolved and its soldiers forced to march with other units, some of them in chains. In July 1866, the provincial army commander, Simón Luengo, led a revolution that deposed Ferreyra.
