The important depôt was again attacked in 1589 by a savage host from the south, called by contemporary historians, ‘Zimbas’:[7] the city was taken by the savages; and after plunder and massacre, it was again occupied by Thomé de Souza Coutinho. In 1592, according to the Mombasah Chronicle, Shaho bin Misham, its last Shirazian Sultan, was succeeded by Ahmad the Shaykh of Melinde. Two years afterwards a fort was built by order of the Viceroy Matthias d’Albuquerque, and in 1596 D. Francisco da Gama re-established the Portuguese rule. If we may believe the Dominican monk João dos Santos, who was present during the war waged with the Monomotapa about the mines of Chicova, the conduct of the European foreigners was ‘outrageous and unreasonable,’ and it soon led to the usual consequences. The first deadly blow against the conqueror was struck by Yusuf bin Ahmad, alias Dom Jeronymo Chingoulia, the Nana Sahib of the Eastern Coast. A son of Ahmad, the first Melinde Sultan of Mombasah, he was sent at an early age to Goa, under the charge of Augustine monks, with orders to bring him up in the true religion; he was baptized in A.D. 1627, and, after writing a submissive letter to the Pope, he was permitted to return home, and was imprudently promoted to the chieftainship in August, A.D. 1630. The convert began by making Moslems eat pork, and by similar demonstrations of zeal. When all suspicions were laid at rest, Yusuf, no longer Jeronymo, collected 300 savages, entered the fortress in order to visit its commander, Pedro Leitão de Gamboa; and at a given signal stabbed the latter with his own hand, whilst his followers killed the captain’s wife and daughter, together with the priest, who was saying mass. The surviving Portuguese barricaded themselves for a week in the Augustine convent, but opened the doors when the young Sultan promised to spare their lives. He at once caused all the wretches to be arrowed, and the holy buildings to be profaned and destroyed. Brave as he was cruel, he defended during three months his city against a large fleet and armament sent by the Viceroy D. Miguel de Noronha, Count of Linhares; he beat off Francisco de Moura, and having captured two Portuguese vessels, he dismantled the citadel, burnt the city, destroyed the trees, and escaped with his ‘Pandis’ to Southern Arabia.
