Why did Camillo Benso, count di Cavour leave the Piedmontese army in 1831?

Camillo Benso, count di Cavour, resigned from the Piedmontese army in 1831 primarily due to the political suspicion he aroused among authorities.1

During his service as an officer in the engineers, Cavour’s revolutionary fervor was fueled by the French Revolution of 1830 and his association with individuals holding radical, republican, and liberal ideas. His activities and political leanings drew the attention of officials, leading to police surveillance and his eventual transfer to a remote mountain fort. It became clear that he could no longer remain in the military, prompting his resignation. Following his departure from the army, his father helped him secure civilian roles, including serving as a village mayor and managing family estates.1
