100,000 men including 30,000 foot soldiers 3,000 arquebusiers 35,000 cavalry, 2,000 elephants The siege of Goa in 1570–1571 was a major military conflict between the Portuguese Empire and an alliance of regional powers in India, led by Ali Adil Shah I.

The Bijapur forces established a camp east of the island of Goa, positioning their infantry ahead of Benastarim and deploying artillery to counter the Portuguese defenses.

However, the Portuguese, under the leadership of Viceroy Dom Luís de Ataíde, 3rd Count of Atouguia, continually repaired their defenses at night when the bombardment ceased.

To deceive the Adil Shahi dynasty artillery and conserve their own resources, the Portuguese lit torches and bonfires at various isolated positions along the riverbanks, creating the illusion of greater readiness and causing the enemy to waste ammunition.

The Luís de Ataíde, 3rd Count of Atouguia strategic acumen played a pivotal role in maintaining the fort's resilience against the prolonged siege.
