Porongos Massacre or Porongos Betrayal was the penultimate confrontation of the Ragamuffin War (1835–1845) and occurred on 14 November 1844. The battle was primarily responsible for ending the longest of Brazil's revolutions. In November 1844, about a year before the end of the conflict, and with peace negotiations already underway, the more than 1,200 republicans, led by General David Canabarro, were surrounded and massacred in the unprotected countryside, due to Canabarro's negligence, according to some, or his treachery, according to others, by the more than 1,100 partisans who supported the Empire, led by Francisco Pedro de Abreu. Because of the siege and the military strategy constructed by Francisco de Abreu, it was possible to defeat the Republicans and, consequently, paralyze the anti-imperial revolutionary movement. Fearing a surprise attack, Antônio Netto decided to camp with his troops further away and ended up escaping defeat. For the revolutionaries, the battle of Porongos resulted in the death of 110 supporters of the republic, the arrest of 333 men - 35 of them officers -, five banners, a cannon, utensils, archives, and more than 1000 horses.
