After undergoing substantial repairs, "Temeraire" was employed blockading the French fleets and supporting British operations off the Spanish coasts. She went out to the Baltic in 1809, defending convoys against Danish gunboat attacks, and by 1810 was off the Spanish coast again, helping to defend Cadiz against a French army. Her last action was against the French off Toulon, when she came under fire from shore batteries. The ship returned to Britain in 1813 for repairs, but was laid up. She was converted to a prison ship and moored in the River Tamar until 1819. Further service brought her to Sheerness as a receiving ship, then a victualling depot, and finally a guard ship. The Admiralty ordered her to be sold in 1838, and she was towed up the Thames to be broken up.
