Curbero subsequently fought in three battles against the French galleons and founded the church of Nuestra Señora del Pilar of Zaragoza.

On June 17, 1689, Curbero obtained from King Charles II of Spain the office of governor and title of "Captain for Lifetime" of San Salvador de la Punta Fortress in Havana, Cuba.

As such Cubero headed to New Mexico in 1697 to assume the governorship of that province, settling in Santa Fe and taking office on July 2, 1697.

On the other hand, Cubero had news about corruption of Diego de Vargas, as well as of the imposed fines against him by Santa Fe council officials.

However, initially, Cubero rejected the levied fines against his predecessor until the official formal charges convinced him that the former governor had embezzled money and impoverished the population through the poor economic management and maldistribution of food supplies among the population of colonial origin, causing famine between 1695 and 1696 (these offenses were punishable by a fine and the prison).
