The rebels fell back on Bauru, from where Isidoro Dias Lopes launched a disastrous attack on the Federal army in the city of Três Lagoas. Fully one third of the rebel troops were killed, severely wounded, or captured. The remainder fled south to Foz do Iguaçu, where they joined up with forces commanded by Luís Carlos Prestes, establishing the largest guerilla force in Brazil to date, the Coluna Prestes. An enquiry conducted by the State of São Paulo soon after the defeat of the rebels found that there had been innumerable cases of destruction and rape in the interior, particularly under the rebel lieutenant , who commanded a group known as the “Death Column.” It also found that a number of colonels in the interior, opposed to Carlos de Campos, had supported the rebellion. Divisional general Abílio Noronha, commander of the 2nd Military Region, that included São Paulo, Mato Grosso and Mato Grosso do Sul, accused certain politicians of being behind the revolt, inciting the soldiers to join it. Another general criticised de Campos’ hasty withdrawal from São Paulo, claiming that with the loyal troops at his disposal he could have defeated the rebels within the city at the start of the revolt. The junior officers and other soldiers who took part in the revolt were amnestied by President Getúlio Vargas shortly after the Revolution of 1930, along with everyone else who had taken part in rebellions in the 1929s. In Perdizes, the revolution of 1924 is still commemorated each year.
