In July 1915, Fox enlisted in the New Zealand Army Nursing Service and left Wellington on board the SS Maheno. The ship sailed to Port Said, Egypt, and the contingent of nurses worked in a stationary hospital there. In October 1915, she was on board the SS Marquette when it was torpedoed by a German submarine at 9.15am. The Marquette was hit on the starboard side and sunk within fifteen minutes, leading to the deaths of Fox and others aboard.[5]
A commemorative plaque to Fox, and fellow Marquette casualties Mary Gorman and Isabel Clark, was placed in Waimate Hospital. The hospital also named its women's ward Marquette in memory of the three nurses.[3] When the hospital closed in 1996, the plaque was moved to a display at the Waimate Museum.[4]
Fox is named on the Mikra British Cemetery in Greece and in the Nurses' Memorial Chapel at Christchurch Hospital.[6] She is also remembered in the Five Sisters window at York Minster in York, England.[2]
