- Native Muslims attack the Spanish garrison with help from a Dutch
squadron that arrives at Jolo from Batavia (North Jakarta) during Spain's colonial rule of the Philippines; the Filipino-Spanish troops
under Commander Esteban Ugalde will resist and finally force the withdrawal of the squadron after three days of combat
in what would be one of the few unsuccessful attempts of the
Dutch to expel the Spaniards from the Philippine islands; the contexts are
Spain's tenuous hold on Mindanao and the so-called 80 Years War of Netherlands' revolt and, subsequently, assertion of its independence; Spain's colonization of the Southeast Asian islands began in the mid 1500s when King Philip II sent sent an expedition to conquer said archipelago in 1559 following earlier exploration missions including that led by Ferdinand Magellan who was killed by the native chieftain Lapu-Lapu and his forces in the island of Mactan.
