In 1941 when Hong Kong was attacked by the Japanese forces, the Jesuits of the College helped organise the evacuation of the Kowloon civilians to the Island as they closed down the school. During the occupation, the Japanese prohibited its resumption on political grounds. The Nelson Street campus was so thoroughly looted that Mr. Chow Ching-nam (周淸霖), then Principal, could only salvage a small portion of school registers and documents, and the students had to bring in their own chairs when the College reopened after the war.
