The federalists demanded further "war loans" not to sack Curitiba.
The population was restless.
It was during this period that Ildefonso Correia Pereira, the Baron of Serro Azul, devised a plan to rid the city from the Maragatos.

The Baron considered fighting in the city unnecessary as it would spill more blood; and so he made the decision to negotiate.
In return for peace and the absence of looting, the Baron secretly lent, with the support of some traders, money to Gumercindo Saraiva, head of the Maragatos.
The negotiations, however, were seen as betrayal by the defenders of Floriano.

Thus, Maragatos left the city in May and Vicente Machado returned to power.
However, Serro Azul and five companions were kidnapped.
They were taken by train towards Paranaguá, under the pretext that they would board a ship headed towards Rio de Janeiro, where they would receive an award, but it was a trap.
The Baron of Serro Azul and his allies were unloaded from the train and shot in the Serra do Mar, accused of treason for negotiating with the Maragatos.
