In April 1938 Agnes Moncrieff, in her role as the YWCA of New Zealand’s foreign secretary to the YWCA of China, wrote to her mother, ‘You do not travel in China at the full moon if you can help. There are always air raids.’ Nessie, as she preferred to be called, was an indomitable spirit and source of strength for many women in China during the Second Sino-Japanese War. There from 1930–1945, she is the only New Zealander to ever be seconded to the YWCA of China. These fascinating excerpts drawn from hundreds of her typed and handwritten letters tell of a remarkable woman, her experiences living and working in China, her observations of Chinese and Japanese military strategies, and her horror at what was taking place around her.
