context_page_description: The Constitutionalist Revolution of 1932 is the name given to the uprising of the population of the Brazilian state of São Paulo against the Brazilian Revolution of 1930 when Getúlio Vargas assumed the nation's Presidency; Vargas was supported by the people, the military and the political elites of Minas Gerais, Rio Grande do Sul and Paraíba. The movement grew out of local resentment from the fact that Vargas ruled by decree, unbound by a Constitution, in a provisional government. The 1930 also affected São Paulo by eroding the autonomy that states enjoyed during the term of the 1891 Constitution and preventing the inauguration of the governor of São Paulo Júlio Prestes in the Presidency of the Republic, while simultaneously overthrowing President Washington Luís, who was governor of São Paulo from 1920 to 1924. These events marked the end of the First Republic. Vargas appointed a northeasterner as governor of São Paulo.
  The Revolution's main goal was to press the provisional government headed by Getúlio Vargas to adopt and then abide by a new Constitution, since the elected President Prestes was kept from taking office.
context_section_description: In the naval theater of conflict the Brazilian Navy has designated a naval task force to block the main port of the State of São Paulo, Port of Santos, aiming to cut the only supply line of the rebels by sea.
  On July 10 the destroyer Mato Grosso (CT-10) left the port of Rio de Janeiro, and the next day, cruiser Rio Grande do Sul escorted by two destroyers Pará (CT-2) and Sergipe (CT-7) also left. To support the mission, the Naval Aviation sent three Savoia-Marchetti S-55A (numbers 1, 4 and 8) and two Martim PM (numbers 111 and 112). These five planes left Galeao on 12 July. All were provisionally based at the coves of the Island of San Sebastian, near the village of Bela village (current Ilha Bela). The Navy also intended to send some Vought Corsair O2U-2A for Vila Bela, but the Naval Aviation did not trust them to operate as floatplanes from the coves of the island. so it decided to expand the small airstrip next to the village so that they could operate with landing gear.
