Donaldson was one of about 40 British employees of the British-owned Pacific Phosphate Company on Nauru when World War I broke out. Nauru was then a German colony. On 6 September 1914, the Germans deported the British employees to Ocean Island, part of the Gilbert and Ellice Islands Protectorate. On 3 November 1914, an Australian force under Colonel W. Holmes, arrived at Ocean Island in the company's ship Messina, reembarked the British employees and returned them to Nauru, which was placed under Australian military control.

The diary gives an account of these events and those preceding and following them.

Dr. Ian Heath submitted this thesis as a requirement for the Master of Arts qualifying course in the Department of History, School of General Studies, at the Australian National University, October 1974. He later completed a PhD at La Trobe University in 1979 titled Land policy in the Solomon Islands.

In June 1973, as Professor of Human Geography in the Research School of Pacific Studies at the ANU, Gerry Ward wrote W. F. Straatmans, a field researcher in Papua New Guinea, instructing him to carry out interviews with Danny Leahy and Jack Fox who were amongst the first Europeans in the Highlands of New Guinea. Pim Straatmans had had long personal relationships with both interviewees.
The interviewees recall pre-War and War-time conditions and tell stories regarding transport, airstrip construction, native labour, gold digging methods, sing sings in the Highlands, Edie Creek, Maprik, Bena Bena, Wewak and Sepik regions, including Danny Leahy's account of rescuing nuns and priests from Catholic mission stations on the Sepik during the War. They remark on some of Danny Leahy's photographs, recalling the deaths of Fr Mauschhauser and Br Eugene in the Chimbu, contact with Fr Van Baar, Fr Ross and Fr Schaefer, and the rivalry between the Catholic and Lutheran missions. They comment on the kiaps Robert Melrose and Jim Taylor and on the hanging of Ludy Schmidt in Rabaul.
In the transcript of a further interview with Chris Ashton of the ABC, Jack Fox, who had been in New Guinea with the Australian occupation forces in 1914, recalls the expedition and German resistance.
