The history said that in October, 500 years ago, the Magellan-Elcano expedition passed by the waters of the Sulu Archipelago in search of the route to their ultimate objective, the Maluku Archipelago in present-day Indonesia. The expedition began in September 1519. But owing to the death of their captain-general, Ferdinand Magellan, in the Battle of Mactan on April 27, 1521, the mission faced debacles. Magellan, according to Antonio Pigafetta, already knew where the Maluku was while in Cebu. But on May 1, 1521 the Cebuanos massacred several officials of the expedition and the rest flew for their lives. They left in Cebu their astronomer who had a crucial role in the navigation. Enrique de Malacca, their Malay translator, also deserted them, leaving the expedition astray in the Sulu Sea for several months.
After the encounter with the armada of the Sultanate of Brunei on July 27, 1521 the expedition returned to the Sulu Sea. Pigafetta, the chronicler of the expedition, recorded that they passed by Sulu and Tagima, the latter an alternative name for Basilan. The archipelago, which was ruled by the Sultan of Sulu, served as a landmark in searching the Maluku.
From Basilan, they went northward toward Zamboanga Peninsula. From there, they relied on coasting the Moro Gulf side of Mindanao, seeing from afar what Pigafetta described as the "citta grande" of the Sultanate of Maguindanao. On October 28, 1521, they left the Philippine waters via Sarangani Island. On November 8, 1521, they finally reached the Maluku.
History said that Tagima witnessed the said journey and proved that a civiization has been existing in this part of the world when earliest recorded circumnavigators voyaged this way. While the exact location cannot be established, Isabela City de Basilan accepts and cradles this historical marker on behalf of the island's freedom and peace loving people of Tagima, which is the present day Basilan.
This historical marker is expected to be one among the tourist destinations in Isabela City. Sustainable tourism is also one among the top priority agenda of the current administration here in the city.
