Anticipating the need to remain in homage until the Sovereign resumed his prerogatives, he went to the General Intendency, in order to destroy all the political papers there so that they should not fall into the hands of the enemy, and sought refuge in the house of the Minister of Russia, who was then in São Pedro de Alcântara.

One of the most exalted Miguelists, Alquilador Troca, perfidiously offered him asylum at his home, but as soon as the Intendant-General entered his house, he rushed to report the case to D. Miguel, who immediately had him arrested and taken to the Queluz Palace.

There he was tied to the trunk of a tree and subjected to a simulacrum of shooting (discharge without bullets), preceded and followed by all sorts of pressure to get him to confess what had happened between the King, the Ministers of foreign Nations and himself in anticipation of the Infante's coup d'état.

At the session of the Chamber of Deputies, on August 26, 1834, he raised the issue of the protests made by D. Miguel I of Portugal, in exile, on June 20 of the same year, against the stipulations of the Évoramonte Concession.

In the session held the following day, he proposed the application of the death penalty to the deposed Sovereign, if he returned to the Country, in accordance with the Law previously promulgated by the Courts against crimes of treason to the nation.

During the aforementioned functions, he was invested with the powers to negotiate Trade and Navigation Treaties between the Portuguese Government and that of the Kingdom of Prussia where he published the work 'Memória sobre a Organización Antiga e Moderna do Army Prussiano' (Lisbon, 1844).
