Over the next four years, strategically important islands and territories had been seized in the treaties of Tilsit and Schönbrunn, giving Napoleon direct command of the eastern shore.
Maintaining control of the Adriatic was however even harder than seizing it had been, the threat of attack by Austrian, Russian or Ottoman armies and the mountainous terrain of the Balkans forcing the development of garrisons that could be effectively resupplied only by sea.
[4] In the aftermath of the Battle of Lissa, the badly wounded Hoste returned to Britain in HMS Amphion leaving Captain James Brisbane in command in the Adriatic.
[5] These dispersed forces continued to have success against French convoys; on 27 November 1811, the independently sailing HMS Eagle foiled an attempt to send supplies to Corfu and captured the unarmed frigate Corceyre.
It was assumed among the British squadron that the convoy comprised Danaé, Flore and Corona, the survivors of the Battle of Lissa now sailing from Trieste to Corfu to supply the island.
[8] Shortly after passing the southern headland of Lissa, the British squadron encountered a neutral merchant ship that had been carrying Lieutenant John McDougal, formerly of HMS Unite, to Malta.
[8] The French convoy was under the command of Commodore François-Gilles Montfort and consisted of three ships, the two large frigates Pomone and Pauline and the smaller Persanne.
[9] Key Casting south close to the island of Augusta (Lastovo), Captain Gordon in Active sighted the French force at 09:20 on 29 November, sailing to the north-west.
[11] At 15:05 another British ship appeared on the horizon, the sloop HMS Kingfisher, which persuaded Montfort that he could no longer protect the battered Pomone against superior numbers.
From external appearances, Persanne seemed to be a frigate of similar size to the fifth rate Unite, but in fact the French ship was only lightly armed, carrying 26 small guns to her opponent's 36.
Ultimately Pomone was transferred to Britain, briefly renamed HMS Ambuscade and broken up for materials while Persanne was sold to the Bey of Tunis.
[12] Nearly four decades later the battle was among the actions recognised by a clasp attached to the Naval General Service Medal, awarded upon application to all British participants still living in 1847.
The French Navy would continue to seek reinforcements for their squadrons, concentrating on the construction of several new ships in Italian seaports that would not be ready until 1812.
