Under the leadership of the able soldiers and captains-general, Juan Niño de Tavora (1626-1632), Sebastián Hurtado de Corcuera (1634-1635), and Diego Fajardo (1644-1653), the audiencia interfered but little with the notable military operations of that period. Exception to this statement must be made in the cases of the capture and relinquishment of the island of Formosa in 1629 and 1642, respectively. The audiencia was unreservedly opposed to the proposed conquest of the island by Governor Tavora, who, nevertheless, undertook the expedition and carried it to a successful conclusion. When Governor Corcuera decided that the position of the Spaniards in Formosa was untenable and resolved to withdraw the garrison, the audiencia was equally forceful in its remonstrances. It sent charges to the court against the governor, alleging that this loss, and that of the Moluccas the year before would assuredly lead to the greater disaster of the loss of the Philippines. [496] The important part played by the audiencia in the defense of Manila against the British in 1762 will be discussed in another chapter. While Governor Rojo and the majority of the oidores were in the city, surrounded by the enemy, Oidor Anda y Salazar, who had been sent to the provinces as visitor, organized and maintained a defense against the enemy. When he was commanded by the governor to surrender, he refused, successfully maintaining the claim that as the sole, legally-appointed oidor who had not surrendered, he was both audiencia and governor, and as such his actions were legal. His claims were recognized and approved by the king. This is perhaps the most peculiar and extraordinary example of the audiencia's assumption of military power.
