The resulting crisis threatened to bring about even more bloodshed. To defuse the situation, a young anthropologist,
Donald Thomson, offered to investigate the causes of the conflict. He travelled to Arnhem Land, on a mission that many said would be suicidal, and got to know and understand the people who lived there. After a seven months’ investigation, he persuaded the Federal Government to free the three men convicted of the killings and returned with them to their own country, living for over a year with their people, documenting their culture. In the course of his negotiations, he wrote of Wonggu sending a
message stick to his sons, at that time in prison, to indicate a calling of a truce. In etched angles, it showed people sitting down together, with Wonggu at the centre, keeping the peace. The message stick is now housed in the
Buku-Larrnggay Mulka Centre at
Yirrkala. He formed a strong bond with the Yolngu people, and in 1941 he persuaded the Army to establish a special reconnaissance force of Yolngu men known as the
Northern Territory Special Reconnaissance Unit, including Wonggu and his sons, to help repel Japanese raids on the northern coastline of Australia. The historian
Henry Reynolds has suggested that the Caledon Bay crisis was a decisive moment in the history of Aboriginal-European relations. ==References==
