During Hyder's regime, the Mangalorean Catholic community continued to flourish. After Hyder's death in the Second Anglo-Mysore War on 7 December 1782, the British captured the fort again. Hyder was succeeded by his son Tipu Sultan. Tipu laid several assaults on the Mangalore fort until January 1784, all of which resulted in failure. The fort was finally delivered to Tipu when the British capitulated on 30 January 1784.
