 Casualties of the operation were not high on either side . British losses in the landing party amounted to 15 killed and 58 wounded , with an additional three missing . The naval squadron suffered no known casualties in the engagement , principally because they did not come under heavy fire . French losses have not been calculated , but apart from General Des Bruslys were probably a similar figure to the British . In contrast , the damage to the morale of the French defenders of Île Bonaparte was severe : the death of Des Bruslys and the failure to properly defend the town undermined their efforts to such a degree that the eventual invasion of the island in 1810 was carried out without significant fighting or loss . This invasion force was similar in size to the raiding party and was once again led by Rowley and Keating .
