 The loss of such a large proportion of his force placed Rowley at a significant disadvantage in September 1810, as Hamelin's squadron, bolstered by the newly commissioned "Iphigénie", now substantially outnumbered his own (the ruined "Néréide" was also attached to the French squadron, but the damage suffered was so severe that the ship never sailed again).Withdrawing to Isle de France, Rowley requested that reinforcements be diverted from other duties in the region to replace his lost ships and to break the French blockade of Île Bourbon, led by Bouvet.These newly arrived British frigates, cruising alone in unfamiliar waters, became targets for Hamelin, who twice forced the surrender of single frigates, only for Rowley to beat his ships away from their prize each time.
