I disembarked in Morotai on 16 April, 1945. While I was on the ship and overseas, Bobbie and I wrote to each other every day. I was not able to keep her letters but, unbeknownst to me, she kept all of mine, organized by the month and tied together in neat bundles kept in a drawer next to her bed. I became aware of them when she was in bed with advanced pulmonary secondaries from a colon cancer. When I found her reading one, in October 1995, she looked at me with an expression of such deep love that I could not bear to read the letters, until October 2001, when I undertook to update my Basser Library archives. They are pretty torrid love letters, but mention facets of my scientific career not available elsewhere. The catalogue of my Basser Library archives contains explanatory notes as well as the letters.

For the rest of the War, until 27 August, 1945, I was based at 1 Aust Corps Headquarters on Morotai, and was involved with malaria control in the attacks on Brunei Bay, Tarakan and Labuan. Throughout these campaigns, the malaria rates were very low, with only 97 cases being admitted to medical units between April 6 and September 7, from a force of 17,000. After hostilities ceased, I visited Brunei, Labuan, Tarakan, Balikpapan and Sarawak. With Francis Ratcliffe, I organized some trials of mosquito control by dispersion of DDT from aircraft. As reflected in my letters to Bobbie, there were long periods of boredom and anxiety about the job with Macfarlane Burnet at the Walter and Eliza Hall Institute.
