On 25 August 1633, Captain Bernardo Arias Montano, governor of Cumaná, sailed from the town with a flotilla of 14 pirogues carrying 95 Spanish soldiers and 200 indios amigos to evict the Dutch from the area.

[1] Sailing along the Borracha Islands and the Píritu Islets, embarking there more native allies, they arrived to the Unare on 28 August and during that night landed undetected on the Uchire beach, half a league from the Dutch outpost.

Arias Montano left 50 men to guard the pirogues and moved with the bulk of his force to attack the fort.

[1] On 30 August at dawn, the Spanish came out the jungle and assaulted the fortress under artillery fire from both its defenders and the Dutch ships.

Arias Montano ordered the outpost to be razed, which was done under the supervision of the engineer Juan Bautista Antonelli, and then reembarked with the prisoners and the booty.
