Royal Navy Mobile Malaria Hygiene unit

My father, a RN gunner, sailed to Hong Kong from Australia on HMS Vindex arriving August 1945. He was involved in the liberation of Stanley Internment camp and never forgot the dreadful scenes he witnessed. He remained in Hong Kong until late 1946 working in the RN Mobile Malaria unit . I understand some of the Japanese guards at the camp were placed in work parties supervised by the RN then taken to clear the area around the south of the island. I have several photos of dad with these Japanese which I will upload to the site if of interest. Dad also took a camera from one of these guards with an underdeveloped film and on having them processed revealed some of the brutality that took place. I have found it difficult to find out about this RN unit and would be grateful if anyone can provide further details. I have had the pleasure of meeting up with 2 of the Barton family that were interned in Stanley, Dan and Rosemary but although very interested in my photographs could not enlighten me anymore. I have twice traveled to Hong Kong and really love the place as I know my dad did. This is a fascinating site, so pleased I gave found it.
