Sánchez's death. On his return, Sanchez held many important positions in government. He was appointed Commander of Arms for the city of Santo Domingo by Jimenes. However, almost immediately after assuming office, Faustin Soulouque, the new ruler of Haiti, ensued a new invasion into the territory. This invasion accumulated into the Battle of Las Carreras, in which Sánchez participated with Mella, Santana, and Antonio Duvergé. Following the decisive victory of the Dominicans, Sánchez wrote a testimony, in which he writes: Serving as Public Defender, on the Court of Appeals and the Supreme Court, his most prolific case was that of Santana's case against war general Antonio Duvergé, in which took place during Santana's campaign in 1849. Although Duvergé would be acquitted, this did not ease the tension between him and Santana due to Santana's pro-annexation plans. Around this time, Sánchez was approached by Pedro E. Pelletier and Pedro Ramón de Mena, conspirators who organized a group seeking to overthrow Santana and reinstall Báez as president. Earlier on March 25, a rebellion that aimed to overthrow Santana failed. Apperently, Duvergé was involved in that conspiracy. As a result, Duvergé, his 23 hear old son, Tomás de la Concha, and many others were executed on Santana's orders on April 11, 1855. When this failed, Sánchez would be exiled to Curaçao for the second time. There, he established a strong relationship with Báez, who realized the importance of being supported by someone of stature such as Sánchez. He would be allowed to return in August 1856 when Santana resigned and Manuel de Regla Mota became president. When Baez returned to office for a second term, Sánchez prepared to support him to expel Santana's influence over the nation. However, when considered for candidacy, Sánchez rejected, believing that Baez made a better candidate. With his presidency, he appointed Sánchez as governor of the province of Santo Domingo and even Commander of Arms for the city, although Sánchez would retain this position in discreet. Interestingly, when José María Cabral took Santana prisoner to Santo Domingo, to later deport him to Martinique, Sánchez allowed Santana to stay at his residence, and even treated him with compassion. This action was met with criticism, especially given the fact that Santana had previously exiled him twice, and even ordered the execution of his aunt and brother some 12 years earlier. On July 7, 1857, Báez faced an uprising Santiago due
