Spooner served in the Second World War and was ordered to Singapore to take up the post of Rear Admiral, Malaya in 1941. When the Japanese launched their invasion of Malaya on 8 December 1941, Spooner initially had two immediate superiors: Admiral Sir Tom Phillips and Vice-Admiral Geoffrey Layton. However, Admiral Philips was killed when his flagship HMS Prince of Wales was sunk along with HMS Repulse on 10 December by Japanese bombers. Then on 5 January 1942, Vice-Admiral Layton, who had replaced Phillips, moved his headquarters to the island of Java to streamline the organization of supply convoys to the Dutch East Indies and Malaya. This left Spooner as the senior naval officer in Singapore. By the end of January, the Royal Navy had almost no real fighting strength left in Malaya, and the decision was taken to abandon Singapore in favor of Java. Most naval personnel were evacuated aboard the merchantman Empire Star on 12 February, but Spooner and a few others remained behind to assist in organizing the evacuation of civilians from the island, which was now just days away from surrender. Spooner's wife was one of those who was evacuated. The evacuations were a dismal affair due to circumstances beyond Spooner's control. The situation had become so dire that anything more than rudimentary coordination was impossible. Furthermore, Japanese naval and air forces operating in the seas around Malaya destroyed many of the ships that left Singapore in the final days before the surrender on 15 February. One of the unfortunate vessels caught up in the attempted escapes was the ML 310 transporting Spooner, Air Vice MarshalConway Pulford and some 40 others. The vessel was attacked by Japanese aircraft and its passengers became stranded on a small island called Chibia. Chibia was part of the Juju group located north of Bangka Island, and was uninhabited. Even worse, there was almost no fresh water. Despite British search efforts, the stranded refugees remained on the island for two months before disease and starvation forced the survivors to surrender to the Japanese. By that time, both Spooner and Pulford had died of exhaustion and malaria.
