On 24 November the mortar and howitzer boats threw several hundred shells into Santa Maria whilst Aetna, Devastation and Thunder, with part of the Spanish flotilla and the British gunboats drew the fire from Catalina. At the beginning of December Aetna burst her large mortar, the fourth time she had done so during the siege. One of these events had resulted in the death of 13 of her crew, and the wounding of numerous others.
