There Rous took part in numerous actions; on the night of 31 August 1812 he took part in the cutting out from the port of Lema, near Venice, of seven vessels loaded with ship timbers for the Venetian government, together with French xebec "Tisiphone" and two gunboats, and on 6 January 1813 the boats of "Bacchante" and the sloop successfully captured five enemy gun-vessels in the neighbourhood of Otranto. On 15 May 1813 he assisted at the capture and destruction of the castle and batteries of Karlobag, and on 12 June he commanded the "Bacchante"s yawl in the capture of seven large gun-boats, three smaller gun-vessels, and 14 merchantmen at Giulianova. The British boats approached and boarded under a heavy fire of grape and musketry, while the Marines landed on shore, driving off 100 enemy troops and capturing two field guns. Rous was put in command of one of the merchantmen, laden with oil, which broached and capsized in heavy weather around midnight, and was only kept afloat by the buoyancy of her cargo. Rous and his prize crew were eventually rescued by another prize around 4 a.m. Into 1814 Rous participated in the capture of Rovigno, the island of Lesina, and the fortresses of Cattaro and Ragusa.
