Following the Japanese invasion of Burma in early 1942, Rushall evacuated from the country with his daughter Nancy. He stayed out the Second World War in Bombay, but eventually returned to Rangoon, where he died on 3 February 1953, at the age of 87. Upon his death, U Kyaw Tha—chairman of the Commissioners of the Port of Rangoon—commended him as a "born gentleman", and praised his work at the city's hospital and his "kindliness and infectious friendliness".
