During the three years that the Japanese took over the Nanjing campus in 1942, serious damages were done to the buildings. Walls were dirty and full of holes. All radiators and furnaces were gone, and so were most furniture, laboratory equipment, and library books. New alterations had been made: a new brick wall, a gatehouse complete with a prison cell, numerous wooden buildings, and military equipment were left behind by the Japanese soldiers. Dr. Davis S. Hsiung planned and supervised rehabilitation of the campus.
