During the Nine Years' War, Spain dispatched a naval convoy under General Pedro de Zubiaur as part of the 4th Spanish Armada to resupply Spanish and Irish forces in Ireland. The convoy of six ships sought anchorage in Castlehaven bay, where Spanish and Irish troops held fortified shore positions to protect the fleet.
On 6 December 1601, the English fleet of four warships commanded by Admiral Richard Leveson engaged the Spanish convoy in the bay off Castlehaven on Ireland's south coast. Despite shore fortifications and 600 troops providing cover, five of the six Spanish ships were sunk, captured, or run aground, while the English squadron suffered no ship losses.
The English victory at Castlehaven denied Spanish forces a critical resupply lifeline on the south coast of Ireland. This outcome weakened the combined Spanish-Irish position and contributed to the broader collapse of Spanish intervention in Ireland, which culminated in the decisive English victory at Kinsale and the effective end of organised Gaelic resistance.
