Many casualties were received from the strenuous fighting in the Wong Nei Chong Gap in which units of the Royal Navy took part . The Principal Medical Officer was again operating for several hours .
On this day the electricity and water supplies failed . The hospital now had to rely on the underground water tanks in its grounds . The water was chlorinated and carried from these tanks in buckets .
The failure of electricity meant that the hospital X - ray apparatus could no longer be used , and this lack of X - rays naturally embarrassed the efficient treatment of casualties .
