 "Iphigenia" was still from Île de Passe at the edge of the lagoon and was low on shot and unable to manoeuvre in the calm weather without anchors.Recognising that resistance under such conditions against an overwhelming force was futile, Lambert negotiated with Hamelin, offering to surrender Île de la Passe if "Iphigenia" and the men on the island were given permission to sail to Île Bourbon unmolested.On the morning of 28 August, Lambert received a message from Hamelin, promising to release all the prisoners under conditions of parole within one month if Île de la Passe and "Iphigenia" were both surrendered without resistance.
