In the course of 1809, Lowe and his Corsicans helped in the capture of Ischia and Procida, as well as of Zante, Cephalonia and Cerigo. For some months, he acted as governor of Cephalonia and Ithaca, and later of Santa Maura. He returned to Britain in 1812, and in January 1813, was sent to inspect a Russo-German legion then being formed. He accompanied the armies of the allies through the campaigns of 1813 and 1814, being present at thirteen important battles. He won praise from Blücher and Gneisenau for his gallantry and judgment. He was chosen to bear to London the news of the first abdication of Napoleon in April 1814.
