Advanced to Knight Commander of the Order of the Bath on 1 January 1944, Power became commander of the 1st Battle Squadron and second in command of the Eastern Fleet with his flag in the battlecruiser in January 1944. He went on to be commander-in-chief of that fleet, renamed the East Indies Fleet, in November 1944, and conducted naval strikes on the Imperial Japanese Army in Borneo and Malaya. Flying his flag in "Cleopatra", the first British ship to enter Singapore since the fall of that city over three years earlier, Power arrived in style to attend the final surrender of the Japanese there in September 1945.
