On the fulfilment of these conditions, the Sultan and his people were to be set at liberty. The treaty was dated in Manila March 3, 1754. The terms were quite impossible of accomplishment, for the Sultan, being still in prison, had no power to enforce commands on his subjects. The war was continued at great sacrifice to the State and with little benefit to the Spaniards, whilst their operations were greatly retarded by discord between the officials of the expedition, the authorities on shore, and the priests. At the same time, dilatory proceedings were being taken against the _Maestre de Campo_ of Zamboanga, who was charged with having appropriated to himself others' share of the war booty. Siargao Island (off the N.E. point of Mindanao Is.) had been completely overrun by the Mahometans; the villages and cultivated land were laid waste, and the Spanish priest was killed. When the Governor Pedro de Arandia arrived in 1754, the Sultan took advantage of the occasion to put his case before him. He had, indeed, experienced some of the strangest mutations of fortune, and Arandia had compassion on him. By Arandia's persuasion, the Archbishop visited and spiritually examined him, and then the Sultan confessed and took the Communion. In the College of Santa Potenciana there was a Mahometan woman who had been a concubine of the Sultan, but who now professed Christianity, and had taken the name of Rita Calderon. The Sultan's wife having died, he asked for this ex-concubine in marriage, and the favour was conceded to him. The nuptials were celebrated in the Governor's Palace on April 27, 1755, and the espoused couple returned to their prison with an allowance of 50 pesos per month for their maintenance. In 1755 all the Sultan's relations and suite who had been incarcerated in Manila, except his son Ismael and a few chiefs, were sent back to Sulu. The Sultan and his chiefs were then allowed to live freely within the city of Manila, after having sworn before the Governor, on bended knees, to pay homage to him, and to remain peaceful during the King's pleasure. Indeed, Governor Arandia was so favourably disposed towards the Sultan Mahamad Alimudin (Ferdinand I.) that personally he was willing to restore him to his throne, but his wish only brought him in collision with the clergy, and he desisted. The British, after the military occupation of Manila in 1763, took up the cause of the Sultan, and reinstated him in Sulu. Then he avenged himself on the Spaniards by fomenting incursions against them in Mindanao, which the Gov.-General, Jose Raon, was unable to oppose for want of resources. The Mahometans, however, soon proved their untrustworthiness to friend and foe alike. Their friendship lasted on the one side so long as danger could thereby be averted from the other, and a certain Datto Teng-teng attacked the British garrison one night at Balambangan and slaughtered all but six of the troops (_vide_ pp. 92, 98).
