James Mackenzie Jack inherited the engineering company W.C. Jack & Co. Ltd. from his father, William Jack, on his death in 1919. He was serving in Salonika with his brother at the time of his father's death. I don't know his brother's name, or if he returned safely to Hong Kong. When my uncle, Leslie Warren, had to wind up C.E. Warren & Co. in May, 1941, James Jack asked him to take over the Jacks branch in Penang while the then MD took six months leave. Jack became a POW and was in the fifth transportation to Japan, where he died in a POW camp on 15 September 1944. Tony Banham's list places him in the Artillery Corps HQ. He was probably an officer in the HKVDC, as he had already served in WW1. There may be more about him in Geoff Emerson's and Tony Banham's books.

Great to have these extra details. Thank you so much for taking the trouble to look them up. I hope to learn more about Jack's role in the Battle for Hong Kong with Tony Banham's help.
