赤柱監獄
During the battle she joined other auxiliary nurses in La Salle College, an emergency hospital on the Hong Kong mainland. Shortly before Hong Kong surrendered to the Japanese on 25 December 1941, the Japanese took over the hospital. Day and other nurses remained in La Salle College until 20 January 1942 when they were interned with the approximately 2,000 other Western civilian men, women and children in the bomb-scarred prison warders quarters of Stanley Prison on the south eastern peninsula of Hong Kong Island. Stanley is in the neck of the peninsular and, as Day wrote in her memoirs, it was "a relatively easy place in which to make a cage with the sea to reinforce the bars."
