In the evening Brigadier Philip Honeywood with 800 soldiers launched an assault on San Sebastián and took the Spanish defenders by surprise; they spiked their guns and withdrew to the citadel.

[8] On 10 October a heavy bombardment opened up the citadel – the Spanish finding themselves outnumbered and no hope of relief decided to surrender.

[5] On 10 October Cobham ordered Major General George Wade to embark with 1,000 soldiers and marines on board four transports to proceed to the bay of Pontevedra.

Meanwhile, with Vigo secure, 2,000 troops were left to hold the place while Cobham also ordered an advance further inland.

A small force came across the town of Redondela but was found undefended, with its old fort in ruins; the British burned and pillaged its stores as well.

Fort Marin which defended the town was the next obstacle and in assault was easily captured by a force of 100 grenadiers led by John Ligonier.

The booty was huge – the total number brought home was 190 iron and 30 brass heavy guns, with 10,000 fire arms, 2,000 barrels of powder, and other stores.
