During World War II, Biuku Gasa and Eroni Kumana were tasked with patrolling the waters of the Solomon Sea near Gizo with Australian coastwatcher Sub-Lieutenant Arthur Reginald Evans, who manned a secret observation post at the top of Kolombangara island's Mount Veve volcano.
They later abandoned Plum Pudding Island and swam to tiny Olasana Island in search of food and water.
