The Lightning Column was the last tenentist uprising, fought in southern Brazil from November 1926. Under the command of general Isidoro Dias Lopes, exiled in Argentina, military and civilian leaders of the government's opposition in Rio Grande do Sul combined incursions across Brazilian borders with uprisings in army garrisons in Rio Grande do Sul. The uprising, contrary to the federal and state governments, intended to indirectly support the Prestes Column, which was in Mato Grosso. Some conspirators anticipated the scheduled date, compromising the campaign plan, which was quickly dismantled by the loyalist army and state forces.

Rio Grande do Sul Revolt of 1924
The Rio Grande do Sul Revolt of 1924 was triggered by tenentist rebels from the Brazilian Army and civilian leaders from the Liberating Alliance on 28–29 October of that year. The civilians, continuing the 1923 Revolution, wanted to remove the governor of Rio Grande do Sul, Borges de Medeiros, while the military were against the president of Brazil, Artur Bernardes. After a series of defeats, in mid-November the last organized stronghold was in São Luiz Gonzaga. In the south, guerrilla warfare continued until the end of the year. From São Luiz Gonzaga, the remnants of the revolt headed out of the state, joining other rebels in the Paraná Campaign and forming the Miguel Costa-Prestes Column.
