The idea was to revolt the 1st Infantry Regiment in Vila Militar, where the command of the 1st Infantry Division and several units was located. With the support of the Realengo Military School, the School of Infantry Sergeants, the 1st Railway Company, the Engineering Battalion, the 15th Cavalry Regiment, the 2nd Artillery Regiment and the Aviation School, it would be possible to force the adhesion of the entire Vila Militar, including the 2nd Infantry Regiment. Escorted by a picket of the 15th Cavalry Regiment, marshal Hermes da Fonseca would assume command in Cascadura, leading a vanguard to face loyalist forces of the Navy, the 3rd Infantry Battalion of the Military Police, the 1st Divisional Cavalry Regiment and the 3rd Machine Gun Company in Méier. Meanwhile, the rearguard would continue to the South Zone via Jacarepaguá, following the Pica-Pau road and Copacabana. Under the cover of the cannons of the forts of Copacabana and Santa Cruz, the two most important in Guanabara Bay, it would reach the president's headquarters in the Catete Palace.
