 To distract French attention from the drifting boats, Pym directed Captain Henry Lambert in "Iphigenia" to sail conspicuously off Port Napoleon, where the main body of the French squadron, led by Hamelin in "Vénus", was based.Pym joined Lambert later in the day and the frigates subsequently returned to the waters of Grand Port by different routes, confusing French observers from the shore as to British intentions.By 13 August, the boats originally intended for the attack had still not been assembled and Pym decided that he could not risk waiting any longer without the French launching a counterattack.
