The Bombing of Singapore (1944–45) was a military campaign conducted by the Allied air forces during World War II. United States Army Air Forces (USAAF) long-range bomber units conducted 11 air raids on Japanese-occupied Singapore between November 1944 and March 1945. Most of these raids targeted the island's naval base and dockyard facilities, and minelaying missions were conducted in nearby waters. After the American bombers were redeployed, the British Royal Air Force assumed responsibility for minelaying operations near Singapore and these continued until 24 May 1945.

The raids had mixed results. While significant damage was inflicted on Singapore's important naval base and commercial port, some raids on these targets were not successful and other attacks on oil storage facilities on islands near Singapore were ineffective. The minelaying campaign disrupted Japanese shipping in the Singapore area and resulted in the loss of three vessels and damage to a further ten, but was not decisive. The Allied air attacks were successful in raising the morale of Singapore's civilian population, who believed that the raids marked the impending liberation of the city. The overall number of civilian casualties from the bombings was low, though civilian workers were killed during attacks on military facilities; one attack rendered hundreds of people homeless.

In the decades after World War I, Britain expanded Singapore Naval Base at Sembawang on Singapore's north coast as part of plans to deter Japanese expansionism in the region (the Singapore strategy).The resulting facility was among the most important in the British Empire and included the large King George VI graving dock and Admiralty IX floating dry dock. The Commonwealth forces allocated to Malaya and Singapore were swiftly defeated in the months after the outbreak of the Pacific War, however, and the island was surrendered to the Japanese on 15 February 1942. Singapore was bombed by Japanese aircraft on a number of occasions during the Battle of Malaya and subsequent fighting on the island itself; these raids caused many civilian deaths.

Singapore Naval Base suffered little damage during the fighting in 1941 and 1942, and became the most important facility of the Imperial Japanese Navy (IJN) outside the Japanese home islands.[6] As was the case under British rule, many locally recruited civilians worked in the base, though the Japanese Navy subjected them to harsh discipline which included physical beatings for minor mistakes as well as imprisonment or execution for theft and leaks of information. The Japanese Second Fleet and Third Fleet were transferred from the central Pacific to Singapore and the nearby Lingga Islands between February and April 1944 to be closer to their sources of fuel oil. These two fleets comprised the main body of the IJN, and operated most of its remaining battleships and aircraft carriers.[8]

The forces allocated to the defence of Singapore were not strong. In early 1945, Japanese air defences for the island included only two Army companies equipped with automatic cannon, some IJN anti-aircraft units, and a small number of fighter aircraft. Some of the anti-aircraft guns were crewed by Malay auxiliaries.[9][10] The effectiveness of what was already an inadequate air defence force was hindered by a lack of coordination between the Army and Navy, shortages of fire control equipment for the guns, and no fire-control radar or barrage balloons being available.[10] Defence against night raids was particularly weak as no night fighters were stationed near Singapore and coordination between the anti-aircraft guns and searchlight units was poor.[11]

In June 1944, the USAAF's XX Bomber Command began flying combat operations with B-29 Superfortress heavy bombers from air bases near Kharagpur in northeastern India.[12] Although the Command's primary role was to attack industrial targets in the Japanese home islands, approximately 50 percent of its missions were undertaken to support other Allied operations in the Pacific.[13] The XX Bomber Command reported to the USAAF's Twentieth Air Force, which was personally directed from Washington, D.C., by the commander of the USAAF General Henry H. Arnold, rather than the Allied theatre commanders in India and China.[14] Major General Curtis LeMay assumed command of XX Bomber Command on 29 August after Arnold relieved its first commander.[15]

Following the Japanese defeat in the Battle of Leyte Gulf in late October 1944, the remnants of the IJN were concentrated into two groups of ships. One group returned to bases in the Inland Sea, while the other was stationed at the Lingga Islands.[16] On 27 October, Arnold suggested to LeMay that the Japanese defeat at Leyte might have increased the importance of Singapore's naval facilities and asked whether XX Bomber Command could attack targets on the island. Little recent intelligence on Singapore was available, and on 30 October a photo-reconnaissance B-29 overflew Singapore for the first time and took good photos of the island. Despite this success, LeMay's staff believed that a daylight attack on Singapore—which required a 4,000 mi (6,400 km) round trip from Kharagpur—could not be successful. Regardless, Arnold ordered that XX Bomber Command attack Singapore.[6]

The first raid on Singapore took place on 5 November 1944. XX Bomber Command dispatched 76 B-29s from their bases around Kharagpur. Because of the extreme range to the target, the aircraft were each armed with only two 1,000 pound bombs; pilots were also instructed to bomb from the lower-than-normal altitude of 20,000 ft (6,100 m), and to maintain a loose formation. The raid's primary target was the King George VI Graving Dock, and the Pangkalanbrandan refinery in northern Sumatra was assigned as the secondary target.[6]

The first B-29s arrived over Singapore Naval Base at 06:44. Bombing was highly accurate, with the lead aircraft putting a bomb within 50 ft (15 m) of the graving dock's caisson gate. The third B-29's bombs landed nearby and other aircraft also scored direct hits on the graving dock, rendering it unserviceable for three months. The bombs which landed in and near the King George VI Graving Dock also damaged the 465 ft (142 m) freighter that was under repair in it at the time. Many of the civilian workers in and around the dock were unable to escape and were killed. The raiders also inflicted damage on other facilities in the naval base. Overall, 53 Superfortresses bombed Singapore Naval Base while seven attacked Pangkalanbrandan refinery. Few Japanese anti-aircraft guns or aircraft fired on the raiders, but two B-29s were lost in accidents.[6][17] This raid was the longest daylight bombing operation to have been conducted up to that time.[18] Following the attack, Japanese soldiers murdered a group of injured Indonesian workers.[17] The damage to the King George VI Graving Dock meant that it could not be used to repair the Japanese battleships damaged at the Battle of Leyte Gulf.[19]

The next raid on Singapore took place in January 1945. Following reports that Japanese warships damaged during the Philippines Campaign were being repaired at Singapore, a force of 47 Superfortresses was dispatched from India to attack the Admiralty IX Floating Dock as well as the King's Dock on the island's south coast. These aircraft took off at about midnight on 10 January and began to arrive over Singapore at 08:20 on 11 January. Only 27 of the attackers struck the docks, and due to heavy anti-aircraft fire from Japanese warships in the Straits of Johor the bombers did not cause any damage. The other aircraft bombed Penang in Malaya, Mergui in Burma and several targets of opportunity, generally without success. Two B-29s were lost during this operation.[11][20][21]

XX Bomber Command conducted a major conventional bombing raid on Singapore Naval Base on 1 February. On that day, 112 B-29s were dispatched, each armed with four 1,000 lb (450 kg) bombs. The raid's primary target, the Admiralty IX Floating Dock, was bombed by 67 of the 88 aircraft that reached Singapore. This attack sank the dry dock and destroyed the 460 ft (140 m) ship berthed inside it. The other 21 aircraft that attacked Singapore bombed the West Wall area of the naval base and destroyed many buildings and some heavy equipment; this area housed the base's main offices. Of the remaining aircraft, 20 diverted and attacked targets in Penang and Martaban. A Japanese fighter shot down one of the B-29s and another Superfortress was destroyed on landing after suffering damage from air attack.[23][24]

The next bombing raid on Singapore took place on 24 February. On that day, 116 B-29s were dispatched to bomb the Empire Dock area at Singapore's southern tip. This was a commercial dock, and was considered by XX Bomber Command planners to be "the only suitable primary target free of stipulations left in this theatre". The bombers were armed with incendiary bombs, and the 105 B-29s which reached Singapore succeeded in burning out 39 percent of the warehouse area near the dock.[27] As a result of the target being obscured by smoke, 26 of the B-29s used blind rather than visual bombing, resulting in poor accuracy and damage to civilian residential and commercial areas near the dock area. The Syonan Shimbun newspaper subsequently reported that 396 people had been made homeless by the raid.[28] USAAF losses from the raid were limited to a single B-29 which crashed after running out of fuel on its way back to India.[29]

XX Bomber Command attacked Singapore again on 2 March. As many of the Command's service units were en route to the Marianas, only 64 B-29s could be dispatched. These aircraft targeted the shop and warehouse area in Singapore Naval Base with 500 lb (230 kg) bombs. The 49 B-29s which reached Singapore bombed this area and added to the damage caused by earlier raids, but the results of the attack were again limited by anti-aircraft fire from Japanese warships. Two B-29s were shot down by anti-aircraft guns.[11][30]

The final two raids conducted by XX Bomber Command before it deployed to the Marianas targeted oil storage facilities on islands in the Singapore area. On 12 March, three B-29 groups were dispatched to attack Bukom and Sebarok islands just off the south coast of Singapore as well as Samboe Island, which is a few miles south near Batam Island in the Dutch East Indies. Each of the groups was assigned a different island and no Japanese anti-aircraft guns or fighters were encountered. Despite this, poor weather meant that the 44 B-29s which reached the target area had to use blind bombing techniques and their attacks caused little damage. The command's final attack before it departed for the Marianas took place on the night of 29/30 March when 29 Superfortresses were sent to attack Bukom Island. In order to train the aircrew for the low-level tactics which were being used against the Japanese home islands, the bombers attacked their targets individually from altitudes between 5,000 ft (1,500 m) and 7,000 ft (2,100 m). This raid destroyed seven of the 49 oil tanks in the island, and a further three were damaged. No B-29s were lost in either attack.[11][30]

XX Bomber Command's attacks on Singapore produced mixed results. The raids on Singapore Naval Base damaged or destroyed many workshops and denied the Japanese the use of the King George VI Graving Dock between late 1944 and early 1945, and the Admiralty IX Dry Dock from February 1945. In addition, workers at the Naval Base did not return to work for some time after each raid, and had to be provided with better pay and rations and additional air-raid shelters. Although the damage inflicted on the Empire Docks area impeded Japanese port operations, the poor condition of the port area also hindered British efforts to rehabilitate Singapore following the war. The attacks on the oil storage tanks on islands near Singapore were less successful, and many were found to still be operable after the Japanese surrender.[38]

The Japanese military's efforts to defend Singapore from air attack were unsuccessful. Due to the weak state of the island's air defences, only nine B-29s were shot down during the American campaign, all of them during daylight raids.[39] Minesweeping operations were also slow, and it took three weeks to declare the port safe after each Allied minelaying raid.[37] The surviving crew members of the American bombers that were shot down met varying fates; a small number linked up with resistance movements such as the Malayan Peoples' Anti-Japanese Army, while others were captured by the Japanese and held in harsh conditions. Those who were captured by the IJN and held at the Naval Base were beheaded. After the war, the Japanese personnel believed responsible for atrocities against these prisoners were tried during the Seletar War Crimes Trials and those found guilty were executed or served long prison sentences.[10]

The air raids on Singapore raised the morale of the island's civilian population. They were seen as heralding Singapore's liberation from Japan's oppressive rule, though civilians were generally careful to hide this belief from Japanese occupation personnel.[40] The B-29s were widely believed to be invulnerable, and civilians were cheered by their apparent ability to attack the Japanese at will. In an attempt to counter this view, the occupation authorities exhibited wreckage from downed B-29s and surviving crew members as well as film footage of a Superfortress being shot down. This propaganda campaign was not successful. The Japanese also failed in their attempts to rouse Singapore's Muslim population against the raids by highlighting damage suffered by a mosque on 11 January and 24 February, the latter a raid which coincided with the celebration of Muhammad's birthday.[41] Another factor which contributed to public support for the raids was that the policy of targeting military installations meant that only a limited number of civilians became casualties, and the American bombing came to be seen as highly accurate.[42] The expectation of further attacks caused the prices of food and other commodities to rise, however, as people stockpiled necessities; Japanese attempts to stop this hoarding and profiteering were not successful.[43]
