93-758: 26 aircraft Second Sino-Japanese War The Easter Sunday Raid was an air attack on Colombo , Ceylon during the Indian Ocean raid by carrier -based aircraft of the Imperial Japanese Navy on 5 April 1942. The Japanese objective was to destroy the Ceylon-based British Eastern Fleet in harbour. The British preemptively dispersed shipping from the harbours before the attacks due to advance warning from intelligence in March 1942, and air reconnaissance during

186-730: A full-scale battle in which Beijing and its port city of Tianjin fell to invading Japanese forces (July–August 1937). , On 11 July, in accordance with the Goso conference, the Imperial Japanese Army General Staff authorized the deployment of an infantry division from the Chōsen Army , two combined brigades from the Kwantung Army and an air regiment composed of 18 squadrons as reinforcements to Northern China. By 20 July, total Japanese military strength in

279-738: A campaign of sabotage and guerrilla warfare . In November 1939, Chinese nationalist forces launched a large scale winter offensive , and in August 1940, communist forces launched the Hundred Regiments Offensive in central China. In December 1941, Japan launched a surprise attack on Pearl Harbor and declared war on the United States. The US increased its aid to China under the Lend-Lease Act , becoming its main financial and military supporter. With Burma cut off,

372-540: A communist victory and the Proclamation of the People's Republic of China in 1949. In China, the war is most commonly known as the "War of Resistance against Japanese Aggression" ( simplified Chinese : 抗日战争 ; traditional Chinese : 抗日戰爭 ), and shortened to "Resistance against Japanese Aggression" ( Chinese : 抗日 ) or the "War of Resistance" (simplified Chinese: 抗战 ; traditional Chinese: 抗戰 ). It

465-719: A demilitarized zone between the Great Wall and Beijing-Tianjin region. Japan aimed to create another buffer zone between Manchukuo and the Chinese Nationalist government in Nanjing. Japan increasingly exploited China's internal conflicts to reduce the strength of its fractious opponents. Even years after the Northern Expedition, the political power of the Nationalist government was limited to just

558-675: A few days too early. The Eastern Fleet, led by Vice Admiral Sir James Somerville , sortied on 30 March and deployed in a patrol area 100 miles (160 km) south of the island. Land-based aerial reconnaissance concentrating on the southeast. The deployments accurately reflected the direction that the Japanese would approach. With no sightings of the Japanese, the Eastern Fleet retired late on 2 April toward Addu Atoll to refuel at Port T , about 600 miles (970 km) southwest of Ceylon. Ships were detached to resume previous commitments;

651-732: A result of Depression -era tariffs ), and a protective buffer state against the Soviet Union in Siberia . As a result, the Japanese Army was widely prevalent in Manchuria immediately following the Japanese victory in the Russo-Japanese War in 1905, where Japan gained significant territory in Manchuria. As a result of their strengthened position, by 1915 Japan had negotiated a significant amount of economic privilege in

744-536: A result of its victory at the end of the war. Japan had also attempted to annex the Liaodong Peninsula following the war, though was forced to return it to China following an intervention by France , Germany , and Russia . The Qing dynasty was on the brink of collapse due to internal revolts and the imposition of the unequal treaties , while Japan had emerged as a great power through its modernization measures. In 1905, Japan successfully defeated

837-410: A six Fulmars from Ratmalana early on 5 April to conduct a line patrol from Bentota , 35 mi (56 km) south of Colombo on the west coast, to Pottuvri on the east coast. Ships were ordered to disperse from the harbours at Colombo and Trincomalee. Cornwall and Dorsetshire left Colombo late on 4 April to rejoin the Eastern Fleet, part of which had started sailing back to Ceylon from Port T after

930-647: A strike on the Japanese fleet and arrived during the attack. According to AMES 254's logs, its radar was operational during the battle and it did not detect the incoming strike. Official post-war technical histories attributed the failure to technical limitations of the radar, and operator error caused by fatigue due to "unequally divided watch-keeping roster." The short time that AMES 254 had been in Colombo may not have been sufficient to train operators to identify false radar echoes produced by local conditions; real echoes may have been mistaken for false echoes Additionally,

1023-779: A term used mainly in foreign and Chinese narratives. The origins of the Second Sino-Japanese War can be traced back to the First Sino-Japanese War of 1894–1895, in which China, then under the rule of the Qing dynasty, was defeated by Japan and forced to cede Taiwan and recognize the full and complete independence of Korea in the Treaty of Shimonoseki . Japan also annexed the Senkaku Islands , which Japan claims were uninhabited, in early 1895 as

1116-648: A testing zone for advanced biplane and new-generation monoplane combat-aircraft designs. The introduction of the advanced A5M "Claude" fighters into the Shanghai-Nanjing theater of operations, beginning on 18 September 1937, helped the Japanese achieve a certain level of air superiority . However the few experienced Chinese veteran pilots, as well as several Chinese-American volunteer fighter pilots, including Maj. Art Chin , Maj. John Wong Pan-yang , and Capt. Chan Kee-Wong, even in their older and slower biplanes, proved more than able to hold their own against

1209-520: Is a period of "total" war. This view of a fourteen-year war has political significance because it provides more recognition for the role of northeast China in the War of Resistance. On the night of 7 July 1937, Chinese and Japanese troops exchanged fire in the vicinity of the Marco Polo (or Lugou) Bridge , a crucial access-route to Beijing. What began as confused, sporadic skirmishing soon escalated into

1302-895: Is known in China as the War of Resistance against Japanese Aggression ( simplified Chinese : 抗日战争 ; traditional Chinese : 抗日戰爭 ). On 18 September 1931, the Japanese staged the Mukden incident , a false flag event fabricated to justify their invasion of Manchuria and establishment of the puppet state of Manchukuo . This is sometimes marked as the beginning of the war. From 1931 to 1937, China and Japan engaged in skirmishes, including in Shanghai and in Northern China. Chinese Nationalist and Communist forces, respectively led by Chiang Kai-shek and Mao Zedong , had fought each other in

1395-621: Is most commonly used because of its perceived objectivity. When the invasion of China proper began in earnest in July 1937 near Beijing , the government of Japan used "The North China Incident" (Japanese: 北支事變/華北事變 , romanized:  Hokushi Jihen/Kahoku Jihen ), and with the outbreak of the Battle of Shanghai the following month, it was changed to "The China Incident" (Japanese: 支那事變 , romanized:  Shina Jihen ). The word "incident" (Japanese: 事變 , romanized:  jihen )

1488-657: The Central Plains War broke out across China, involving regional commanders who had fought in alliance with the Kuomintang during the Northern Expedition, and the Nanjing government under Chiang. The Chinese Communist Party (CCP) previously fought openly against the Nanjing government after the Shanghai massacre of 1927 , and they continued to expand during this protracted civil war. The Kuomintang government in Nanjing decided to focus their efforts on suppressing

1581-667: The Chinese Civil War since 1927. In late 1933, Chiang Kai-shek encircled the Chinese Communists in an attempt to finally destroy them, forcing the Communists into the Long March , resulting in the Communists losing around 90% of their men. As a Japanese invasion became imminent, Chiang still refused to form a united front before he was placed under house arrest by his subordinates who forced him to form

1674-818: The German Empire 's sphere of influence in Shandong province, leading to nationwide anti-Japanese protests and mass demonstrations in China. The country remained fragmented under the Beiyang Government and was unable to resist foreign incursions. For the purpose of unifying China and defeating the regional warlords, the Kuomintang (KMT) in Guangzhou launched the Northern Expedition from 1926 to 1928 with limited assistance from

1767-855: The Mukden incident in September 1931. Japanese soldiers set off a bomb on the Southern Manchurian Railroad in order to provoke an opportunity to act in "self defense" and invade outright. Japan charged that its rights in Manchuria, which had been established as a result of its victory in 1905 at the end of the Russo-Japanese War , had been systematically violated and there were "more than 120 cases of infringement of rights and interests, interference with business, boycott of Japanese goods, unreasonable taxation, detention of individuals, confiscation of properties, eviction, demand for cessation of business, assault and battery, and

1860-578: The Neutrality Acts of the 1930s . In addition, due to China's fractured political status, Japan often claimed that China was no longer a recognizable political entity on which war could be declared. In Japanese propaganda , the invasion of China became a crusade (Japanese: 聖戦 , romanized:  seisen ), the first step of the "eight corners of the world under one roof" slogan (Japanese: 八紘一宇 , romanized:  Hakkō ichiu ). In 1940, Japanese Prime Minister Fumimaro Konoe launched

1953-531: The Russian Empire in the Russo-Japanese War , gaining Tailen and southern Sakhalin and establishing a protectorate over Korea. In 1911, factions of the Qing Army uprose against the government, staging a revolution that swept across China's southern provinces. The Qing responded by appointing Yuan Shikai , commander of the loyalist Beiyang Army , as temporary prime minister in order to subdue

2046-647: The Second United Front in late 1936 in order to resist the Japanese invasion together. The full-scale war began on 7 July 1937 with the Marco Polo Bridge incident near Beijing , which prompted a full-scale Japanese invasion of the rest of China. The Japanese captured the capital of Nanjing in 1937 and perpetrated the Nanjing Massacre . After failing to stop the Japanese capture of Wuhan in 1938, then China's de facto capital at

2139-668: The Shanghai French Concession , areas which were outside of China's control due to the treaty port system. Japan moved into these areas after its 1941 declaration of war against the United States and the United Kingdom. Building on the hard-won victory in Shanghai, the IJA advanced on and captured the KMT capital city of Nanjing (December 1937) and Northern Shanxi (September – November 1937). Upon

2232-603: The Soviet Union . The National Revolutionary Army (NRA) formed by the Kuomintang swept through southern and central China until it was checked in Shandong, where confrontations with the Japanese garrison escalated into armed conflict. The conflicts were collectively known as the Jinan incident of 1928, during which time the Japanese military killed several Chinese officials and fired artillery shells into Jinan. According to

2325-731: The Taisei Yokusankai . When both sides formally declared war in December 1941, the name was replaced by " Greater East Asia War " (Japanese: 大東亞戰爭 , romanized:  Daitōa Sensō ). Although the Japanese government still uses the term "China Incident" in formal documents, the word Shina is considered derogatory by China and therefore the media in Japan often paraphrase with other expressions like "The Japan–China Incident" (Japanese: 日華事變/日支事變 , romanized:  Nikka Jiken/Nisshi Jiken ), which were used by media as early as

2418-904: The United States Army Air Forces airlifted material over the Himalayas . In 1944, Japan launched Operation Ichi-Go , the invasion of Henan and Changsha . In 1945, the Chinese Expeditionary Force resumed its advance in Burma and completed the Ledo Road linking India to China. China launched large counteroffensives in South China and repulsed a failed Japanese invasion of West Hunan and recaptured Japanese occupied regions of Guangxi . Japan formally surrendered on 2 September 1945, following

2511-592: The atomic bombings of Hiroshima and Nagasaki , Soviet declaration of war and subsequent invasions of Manchukuo and Korea . The war resulted in the deaths of around 20 million people, mostly Chinese civilians. China was recognized as one of the Big Four Allies , regained all territories lost, and became one of the five permanent members of the United Nations Security Council . The Chinese Civil War resumed in 1946, ending with

2604-485: The 18 September 1931 Japanese invasion of Manchuria marks the start of the War of Resistance. Although not the conventional Western view, British historian Rana Mitter describes this Chinese trend of historical analysis as "perfectly reasonable". In 2017, the Chinese government officially announced that it would adopt this view. Under this interpretation, the 1931–1937 period is viewed as the "partial" war, while 1937–1945

2697-596: The 1921 and 1927 Imperial Eastern Region Conferences reconfirmed Japan's commitment to be the dominant power in the Northeast. The 1929 Red Army victory shook that policy to the core and reopened the Manchurian problem. By 1930, the Kwantung Army realized they faced a Red Army that was only growing stronger. The time to act was drawing near and Japanese plans to conquer the Northeast were accelerated. In 1930,

2790-594: The 1930s. The name "Second Sino-Japanese War" is not commonly used in Japan as the China it fought a war against in 1894 to 1895 was led by the Qing dynasty , and thus is called the Qing-Japanese War (Japanese: 日清戦争 , romanized:  Nisshin–Sensō ), rather than the First Sino-Japanese War . Another term for the second war between Japan and China is the "Japanese invasion of China",

2883-510: The 1931 Japanese invasion of Manchuria . According to historian Rana Mitter , historians in China are unhappy with the blanket revision, and (despite sustained tensions) the Republic of China did not consider itself to be in an ongoing war with Japan over these six years. It is also referred to as part of the "Global Anti-Fascist War". In Japan, nowadays, the name "Japan–China War" ( Japanese : 日中戦争 , romanized :  Nitchū Sensō )

2976-612: The 1937 " Sword March ", which—with slightly reworked lyrics—became the National Revolutionary Army's standard marching cadence and popularized the racial epithet guizi to describe the Japanese invaders. The Imperial General Headquarters (GHQ) in Tokyo, content with the gains acquired in northern China following the Marco Polo Bridge Incident, initially showed reluctance to escalate

3069-545: The Beijing-Tianjin area exceeded 180,000 personnel. The Japanese gave Sung and his troops "free passage" before moving in to pacify resistance in areas surrounding Beijing (then Beiping) and Tianjin. After 24 days of combat, the Chinese 29th Army was forced to withdraw. The Japanese captured Beijing and the Taku Forts at Tianjin on 29 and 30 July respectively, thus concluding the Beijing-Tianjin campaign. However,

3162-474: The Chinese Communists through the Encirclement Campaigns , following the policy of "first internal pacification, then external resistance" (Chinese: 攘外必先安內 ). The internecine warfare in China provided excellent opportunities for Japan, which saw Manchuria as a limitless supply of raw materials, a market for its manufactured goods (now excluded from the markets of many Western countries as

3255-628: The Chinese to deploy troops in their own city. In Manchukuo there was an ongoing campaign to pacify the Anti-Japanese Volunteer Armies that arose from widespread outrage over the policy of non-resistance to Japan. On 15 April 1932, the Chinese Soviet Republic led by the Communists declared war on Japan. In 1933, the Japanese attacked the Great Wall region. The Tanggu Truce established in its aftermath, gave Japan control of Rehe Province , as well as

3348-605: The Japanese Army had been given orders not to advance further than the Yongding River. In a sudden volte-face , the Konoe government's foreign minister opened negotiations with Chiang Kai-shek's government in Nanjing and stated: "Japan wants Chinese cooperation, not Chinese land." Nevertheless, negotiations failed to move further. The Ōyama Incident on 9 August escalated the skirmishes and battles into full scale warfare. The 29th Army's resistance (and poor equipment) inspired

3441-531: The Japanese destroyer Isokaze . The prisoners claimed to have taken off from Colombo instead of Koggala, and this was reported to the fleet flagship Akagi late on 4 April; Koggala was not struck during the raid. The prisoners also denied making any reports; this was undermined when the Japanese intercepted a signal from Colombo asking QL-A to repeat its report, indicating that surprise was lost. Catalina FV-R from 205 Squadron RAF, piloted by Flight Lieutenant "Jock" Graham, took off at 17:45 and took over shadowing

3534-410: The Japanese fleet during the raid. The only air reinforcement to Ceylon in the two months after 7 December 1941 consisted of the first Catalina. By 4 April, there were seven operational aircraft; four RAF, two Royal Canadian Air Force (RCAF), and one Dutch. Two RAF and three Dutch were unserviceable, with at least some being overhauled at Bangalore . Two more RCAF aircraft arrived on 6 and 7 April after

3627-630: The Japanese fleet. FV-R made reports at 22:37, and on 5 April at 00:45 and 06:15. The last reported Japanese ships 110 miles (180 km) and 195 degrees from Dondra Head , the southern tip of Ceylon. The Catalina was shot down by Japanese fighters about 90 minutes after making the final report, with the loss of the entire crew. Within an hour of QL-A's report, D’Albiac met with his subordinates to discuss an anticipated Japanese strike after dawn. 222 Group issued Operation Order No. 43 before midnight to warn subordinate units, and units went on alert at 04:00 on 5 April. Per Operation Order No. 43, 803 NAS launched

3720-446: The Japanese force, commanded by Admiral Chūichi Nagumo , was five aircraft carriers; Akagi , Shōkaku and Zuikaku in Carrier Division 5, and Sōryū and Hiryū in Carrier Division 2. Japanese preparations were detected by Allied intelligence. The British defensive plan was based on assessments from the Far East Combined Bureau (FECB), which expected a "C day" of 1 April. As a result, British forces at Ceylon went on alert

3813-465: The Japanese intercepted most of the attack with A2N and A4N fighters from the aircraft carriers Hosho and Ryujo , shooting down several of the Chinese planes while losing a single A4N in the dogfight with Lt. Huang Xinrui in his P-26/281; the Japanese Army reinforcements succeeded in landing in northern Shanghai. The Imperial Japanese Army (IJA) ultimately committed over 300,000 troops, along with numerous naval vessels and aircraft, to capture

3906-468: The Japanese strongholds in Shanghai, leading to bitter street fighting. In an attack on the Japanese cruiser Izumo , Kuomintang planes accidentally bombed the Shanghai International Settlement , which led to more than 3,000 civilian deaths. In the three days from 14 August through 16, 1937, the Imperial Japanese Navy (IJN) sent many sorties of the then-advanced long-ranged G3M medium-heavy land-based bombers and assorted carrier-based aircraft with

3999-415: The Japanese-backed East Hebei Autonomous Council and the Hebei–Chahar Political Council were established. There in the empty space of Chahar the Mongol military government was formed on 12 May 1936. Japan provided all the necessary military and economic aid. Afterwards Chinese volunteer forces continued to resist Japanese aggression in Manchuria, and Chahar and Suiyuan . Some Chinese historians believe

4092-406: The League of Nations. No country took action against Japan beyond tepid censure. From 1931 until summer 1937, the Nationalist Army under Chiang Kai-shek did little to oppose Japanese encroachment into China. Incessant fighting followed the Mukden Incident. In 1932, Chinese and Japanese troops fought the January 28 Incident battle. This resulted in the demilitarization of Shanghai , which forbade

4185-447: The Middle East for 30 and 261 Squadrons RAF; a Hurricane from 30 Squadron was lost in a crash at sea on 4 April. On 5 April, there were 37 or 38 serviceable Hurricanes near Colombo. By 4 April, there were 803 and 806 Naval Air Squadrons (NAS) from the FAA, and 44 Fairey Fulmars . The number of anti-aircraft guns increased to 144 by 4 April. 222 Group also received Consolidated PBY Catalina flying boats, which spotted and shadowed

4278-432: The QL-A report. At 05:45 on 5 April, Catalina BN-L of 240 Squadron RAF, piloted by Flight Lieutenant Bradshaw, took off to shadow the Japanese fleet. The Japanese carriers began flying off 91 bombers and 36 fighters for the strike on Colombo shortly after 06:00 on 5 April. Shortly after 06:40, Catalina BN-L spotted four Japanese aircraft flying north but misidentified them as Hurricanes and made no report. The flying boat

4371-453: The airbase at 07:45 as Hurricanes from 30 Squadron RAF were taking off in ones and twos. 21 Hurricanes took off (four were still on the ground when the first bombs fell) and another – the commanding officer's – was disabled attempting to take-off. Six Fulmars from 803 and 806 NAS also took off from Ratmalana. These British fighters were fully occupied defending the airbase, and were aided by heavy cloud cover. The first Hurricanes airborne attacked

4464-502: The area of the Yangtze River Delta . Other sections of China were essentially in the hands of local Chinese warlords. Japan sought various Chinese collaborators and helped them establish governments friendly to Japan. This policy was called the Specialization of North China ( 華北特殊化 ; huáběitèshūhùa ), more commonly known as the North China Autonomous Movement. The northern provinces affected by this policy were Chahar , Suiyuan , Hebei , Shanxi , and Shandong. This Japanese policy

4557-506: The bombers before any bombs were dropped. Five Vals and a Zero were destroyed, and up to six more Vals were damaged. In exchange, eight Hurricanes and three Fulmars were shot down. The airbase suffered little damage. 19 Vals from Shokaku attacked the harbour around 07:50; they ultimately sank the armed merchant cruiser HMS  Hector and damaged the submarine depot ship Lucia . They were set upon by 258 Squadron RAF shortly afterwards, which decided to concentrate on bombers rather than

4650-472: The buildings. Koggala Airport Prior to the Second World War , the lake at Koggala was used for seaplanes . After the Japanese occupation of the Malay Peninsula in 1942, the RAF needed a new seaplane base. In March 1942 RAF Koggala consisted of forty people, one PBY Catalina flying boat and no outlet to the sea from the lagoon. Within a month more than a hundred more personnel arrived (mostly from Singapore) and construction began on establishing

4743-404: The capture of Nanjing, Japanese committed massive war atrocities including mass murder and rape of Chinese civilians after 13 December 1937, which has been referred to as the Nanjing Massacre . Over the next several weeks, Japanese troops perpetrated numerous mass executions and tens of thousands of rapes. The army looted and burned the surrounding towns and the city, destroying more than a third of

4836-428: The central and eastern Indian Oceans. Upon Japan's entry into the Second World War, the air defences on Ceylon consisted of only four obsolescent three-inch anti-aircraft guns at Trincomalee. The sole RAF squadron was 273 Squadron based at China Bay near Trincomalee; it flew four Vickers Vildebeest and four Fairey Seals torpedo bombers . With the loss of Singapore in February 1942, British planners identified

4929-411: The city's large foreign community and increase China's foreign support. On 13 August 1937, Kuomintang soldiers attacked Japanese Marine positions in Shanghai, with Japanese army troops and marines in turn crossing into the city with naval gunfire support at Zhabei , leading to the Battle of Shanghai. On 14 August, Chinese forces under the command of Zhang Zhizhong were ordered to capture or destroy

5022-402: The city. After more than three months of intense fighting, their casualties far exceeded initial expectations. On 26 October, the IJA captured Dachang, a key strong-point within Shanghai, and on 5 November, additional reinforcements from Japan landed in Hangzhou Bay. Finally, on 9 November, the NRA began a general retreat. Japan did not immediately occupy the Shanghai International Settlement or

5115-452: The conflict into a full-scale war. Following the shooting of two Japanese officers who were attempting to enter the Hongqiao military airport on 9 August 1937, the Japanese demanded that all Chinese forces withdraw from Shanghai; the Chinese outright refused to meet this demand. In response, both the Chinese and the Japanese marched reinforcements into the Shanghai area. Chiang concentrated his best troops north of Shanghai in an effort to impress

5208-448: The country. China was reduced to a fractured state. As a result, China's prosperity began to wither and its economy declined. This instability presented an opportunity for nationalistic politicians in Japan to press for territorial expansion. In 1915, Japan issued the Twenty-One Demands to extort further political and commercial privilege from China, which was accepted by the regime of Yuan Shikai. Following World War I , Japan acquired

5301-431: The country. Yuan's attempts at restoring the monarchy triggered the National Protection War , and Yuan Shikai was overthrown after only a few months. In the aftermath of Shikai's death in June 1916, control of China fell into the hands of the Beiyang Army leadership. The Beiyang government was a civilian government in name, but in practice it was a military dictatorship with a different warlord controlling each province of

5394-414: The covering Zeros. One Val was shot down, and damaged another, in exchange for eight Hurricanes destroyed and two badly damaged. The Shokaku Vals fully occupied 258 Squadron RAF, allowing the remaining bombers to attack the harbour and port unimpeded by British fighters. Five Vals from Zuikaku damaged the British tanker San Cirilo . 53 Nakajima B5N "Kate" torpedo bombers, acting as level bombers, sank

5487-436: The engagement pre-positioned in the air. At 07:30, an advance force of nine Zero fighters from Hiryu flew over the Colombo Racecourse airbase and were spotted from the ground. The 14 Hurricanes of 258 Squadron RAF took off in good order by 07:35 and climbed toward the harbour. The airbase avoided attack. At 07:40, 38 Aichi D3A "Val" bombers from Shokaku and Zuikaku were spotted from Ratmalana. 14 from Zuikaku attacked

5580-403: The expectation of destroying the Chinese Air Force . However, the Imperial Japanese Navy encountered unexpected resistance from the defending Chinese Curtiss Hawk II / Hawk III and P-26/281 Peashooter fighter squadrons; suffering heavy (50%) losses from the defending Chinese pilots (14 August was subsequently commemorated by the KMT as China's Air Force Day ). The skies of China had become

5673-426: The fleet of Admiral Chuichi Nagumo on 4 April 1942 off the coast of Ceylon. Two Sunderlands from Koggala rescued a group of wounded Chindits from Burma in June 1944. After the loss of Singapore by the British, the QEA / Imperial Airways flight from London to Sydney lost Singapore , its refueling point between Calcutta and Perth, Western Australia . It was vital to the British / Australian war effort that

5766-408: The flight be maintained at any cost, so an alternate route was established through Koggala. In 1943 205 Squadron reestablished a link, flying direct from Koggala lake to the Swan River at Perth, on what was at the time the world's longest non-stop air route. Using Consolidated PBY Catalina flying boats each flight carried three passengers, and 60 kilograms (130 lb) of mail. At 28 hours, the flight

5859-453: The heavy cruisers HMS  Cornwall and HMS  Dorsetshire were sent to Colombo, and HMS  Hermes to Trincomalee. Ceylon air defences stood down, but long range Catalina patrols continued. The Japanese cancelled a planned reconnaissance of Colombo harbour on 4 April by cruiser floatplanes. Before dawn on 4 April, Catalina QL-A of 413 Squadron RCAF, piloted by Squadron Leader Leonard Birchall , took off from Koggala to patrol

5952-405: The investigation results of the Association of the Families of the Victims of the Jinan massacre, it showed that 6,123 Chinese civilians were killed and 1,701 injured. Relations between the Chinese Nationalist government and Japan severely worsened as a result of the Jinan incident. As the National Revolutionary Army approached Beijing, Zhang Zuolin decided to retreat back to Manchuria, before he

6045-562: The island as essential to the defence of India and Allied lines of communication through the Indian Ocean . The threat of Japanese carrier-borne air attack was recognized from the examples of Pearl Harbor in December 1941 and Darwin in February 1942. Ceylon's air defences were reinforced in early 1942. Eight Hawker Hurricane fighters arrived on 23 February; they flew in from Karachi where they had been assembled from crates delivered by Cefn-Y-Bryn . 60 Hurricanes arrived on 6 and 7 March; they were ferried by HMS  Indomitable from

6138-541: The old destroyer HMS  Tenedos , damaged the merchant ship Benledi , and hit port facilities. In addition, the Norwegian tanker Soli was sunk and the British freighter Clan Murdoch was damaged. The Japanese strike was recovered by their carriers from 09:45 to 10:30. Carrier Division 5 reserve strike force was armed with high explosive bombs for a second strike on Colombo. This was cancelled when Japanese scout aircraft discovered Dorsetshire and Cornwall at 10:00 on 5 April. Carrier Division 5 reserve strike force

6231-456: The oppression of Korean residents". After five months of fighting, Japan established the puppet state of Manchukuo in 1932, and installed the last Emperor of China, Puyi , as its puppet ruler. Militarily too weak to challenge Japan directly, China appealed to the League of Nations for help. The League's investigation led to the publication of the Lytton Report , condemning Japan for its incursion into Manchuria, causing Japan to withdraw from

6324-426: The radar antenna projected " lobes " in which objects might be detected, with gaps between lobes or lobes overlapping. The height of an object heavily affected detection range. The trajectory of the incoming Japanese aircraft may have inadvertently taken advantage in gaps between lobes. AMES 254 may simply not have had enough time to process the radar data, especially if operator fatigue was a factor. The terrain around

6417-492: The radar limited maximum range to 60 mi (97 km). The distance travelled by Japanese aircraft between the edge of that radius to Ratmalana was 54 mi (87 km), and could be covered by a Zero at cruise speed in about 17 minutes. During the battle it took five minutes for the Hurricanes to take off and another six to climb to interception altitude. This left only six minutes for AMES 254 to report to No. 20 Operations Room and for orders to be issued to pilots. Birchall

6510-404: The raid started. Squadrons operating Catalinas included 205 Squadron RAF and 413 Squadron RCAF . Other air reinforcements included maritime and naval strike aircraft. The airbases at Ratmalana , near Colombo, and China Bay were expanded. Another was established at the Colombo Racecourse to relieve congestion at Ratmalana. The Catalinas operated from Koggala and the adjacent lagoon , near

6603-659: The raid. The attacking Japanese aircraft were met by fighters of the Royal Air Force 's (RAF) 222 Group , commanded by Air Vice-Marshal John D'Albiac , and the Royal Navy 's Fleet Air Arm (FAA), and anti-aircraft artillery. Port facilities were damaged, and ships both in harbour and – having dispersed – on the ocean were sunk or damaged. The bulk of the British Eastern Fleet was not found and survived. The raid demonstrated Ceylon's vulnerability; British forces were not prepared to face further Japanese carrier raids. The Eastern Fleet relocated its main base to East Africa , from which it regularly deployed carrier task forces into

6696-421: The region by pressuring Yuan Shikai , the president of the Republic of China at the time. With a widened range of economic privileges in Manchuria, Japan began focusing on developing and protecting matters of economic interests. This included railroads, businesses, natural resources, and a general control of the territory. With its influence growing, the Japanese Army began to justify its presence by stating that it

6789-406: The revolution. Yuan, wanting to remain in power, compromised with the revolutionaries, and agreed to abolish the monarchy and establish a new republican government, under the condition he be appointed president of China. The new Beiyang government of China was proclaimed in March 1912, after which Yuan Shikai began to amass power for himself. In 1913, the parliamentary political leader Song Jiaoren

6882-568: The sleek A5Ms in dogfights , and it also proved to be a battle of attrition against the Chinese Air Force. At the start of the battle, the local strength of the NRA was around five divisions, or about 70,000 troops, while local Japanese forces comprised about 6,300 marines. On 23 August, the Chinese Air Force attacked Japanese troop landings at Wusongkou in northern Shanghai with Hawk III fighter-attack planes and P-26/281 fighter escorts, and

6975-556: The southern tip of the island. The Japanese were unaware of the bases at the Colombo Racecourse and Koggala. Colombo and Trincomalee each received a radar station. The Colombo radar station unit was AMES 254. Its personnel arrived on 18 March and its equipment on 22 March. The station became operational at the Royal Colombo Golf Club – about 6 miles (9.7 km) north of Ratmalana – on 25 March, and

7068-409: The southernmost patrol sector. Later that day, the crew decided to repeat an assigned leg that took them to the southern-most point of their patrol; the repetition was conducted for navigational purposes. At 16:00, at the southern-most point of the repeated leg, QL-A spotted the Japanese fleet on the southern horizon about 360  mi (310  nmi ; 580  km ) south-east of Ceylon. The flying boat

7161-551: The tensions in the Northeast that led to the Mukden Incident and eventually the Second Sino-Japanese War. The Soviet Red Army victory over Xueliang's forces not only reasserted Soviet control over the CER in Manchuria but revealed Chinese military weaknesses that Japanese Kwantung Army officers were quick to note. The Soviet Red Army performance also stunned the Japanese. Manchuria was central to Japan's East Asia policy. Both

7254-727: The time, the Nationalist government relocated to Chongqing in the Chinese interior. After the Sino-Soviet Non-Aggression Pact , Soviet aid bolstered the National Revolutionary Army and Air Force . By 1939, after Chinese victories at Changsha and with Japan's lines of communications stretched deep into the interior, the war reached a stalemate. The Japanese were unable to defeat Chinese Communist Party forces in Shaanxi , who waged

7347-462: The war the airport began to develop as a land base. A tarmac runway was laid down and Air Ceylon operated services to and from Koggala by Douglas DC-3 Dakota aeroplanes. In 1964, the Dakotas were replaced by Avro 748 and Nord Aviation 262 aircraft. These services were terminated following the closure of Air Ceylon in 1978. Koggala continued as a Sri Lanka Air Force base. The current runway

7440-515: The water runway and the requirements for a large flying boat base. (slip ways to take boats out of the water, cover etc.) and by the end of 1942 there were over 800 personnel at the base. It became the largest flying-boat base in the east. The RAF flew Consolidated PBY Catalinas and Short Sunderlands initially No. 205 Squadron RAF and No 413 Squadron RCAF and later on of No. 202 Squadron RAF , No. 204 Squadron RAF and No. 230 Squadron RAF. A Catalina of 413 Squadron operating from Koggala located

7533-554: Was assassinated by the Kwantung Army in 1928. His son, Zhang Xueliang , took over as the leader of the Fengtian clique in Manchuria. Later in the same year, Zhang declared his allegiance to the Nationalist government in Nanjing under Chiang Kai-shek , and consequently, China was nominally reunified under one government. The July–November 1929 conflict over the Chinese Eastern Railroad (CER) further increased

7626-480: Was also called the "Eight Years' War of Resistance" (simplified Chinese: 八年抗战 ; traditional Chinese: 八年抗戰 ), but in 2017 the Chinese Ministry of Education issued a directive stating that textbooks were to refer to the war as the "Fourteen Years' War of Resistance" (simplified Chinese: 十四年抗战 ; traditional Chinese: 十四年抗戰 ), reflecting a focus on the broader conflict with Japan going back to

7719-406: Was assassinated ; it is generally believed Yuan Shikai ordered the assassination. Yuan Shikai then forced the parliament to pass a bill to strengthen the power of the president and sought to restore the imperial system , becoming the new emperor of China. However, there was little support for an imperial restoration among the general population, and protests and demonstrations soon broke out across

7812-446: Was attacked by at least 12 Mitsubishi A6M Zero fighters as it closed to get an accurate sighting. The radio was destroyed mid-transmission so that the sighting, but not the size of the fleet, was reported. Within seven minutes, QL-A was forced to make an emergency landing on the ocean. Strafing Zeroes sank the flying boat and killed two crew members in the water. Only six of the nine crew, including Birchall, survived to be captured by

7905-652: Was awarded the Distinguished Flying Cross for the sighting made by Catalina QL-A on 4 April, and was called the "Saviour of Ceylon" by Canadian media. He was a prisoner of war for the remainder of the war.

7998-455: Was connected by telephone to the No. 20 Operations Room on 28 March. The station at Trincomalee was established by AMES 272. The initial IJN order authorizing the raid ("Operation C") was issued on 9 March 1942. By 16 March, the plan was to depart from Staring Bay , Celebes , on 26 March for an attack on Colombo ("C day") on 5 April; these dates were honoured in the actual execution. The core of

8091-676: Was fought between the Republic of China and the Empire of Japan between 1937 and 1945, following a period of war localized to Manchuria that started in 1931. It is considered part of World War II , and often regarded as the beginning of World War II in Asia. It was the largest Asian war in the 20th century and has been described as "the Asian Holocaust ", in reference to the scale of Japanese war crimes against Chinese civilians. It

8184-575: Was most effective in the area of what is now Inner Mongolia and Hebei. In 1935, under Japanese pressure, China signed the He–Umezu Agreement , which forbade the KMT to conduct party operations in Hebei. In the same year, the Chin–Doihara Agreement was signed expelling the KMT from Chahar. Thus, by the end of 1935 the Chinese government had essentially abandoned northern China. In its place,

8277-695: Was ordered to attack the British cruisers, but rearming with torpedoes encountered delays, and the cruisers were sunk by Carrier Division 2 instead. 30 Squadron RAF had seven serviceable aircraft by nightfall. Eight Hurricanes had been shot down, and several damaged. Five pilots were killed and two wounded. 258 Squadron RAF suffered eight Hurricanes shot down and two badly damaged, as well as five pilots killed and two wounded. 803 and 806 NAS suffered four Fulmars shot down and three pilots killed. Six Fairey Swordfish from 788 Naval Air Squadron were also shot down; they were transferring from China Bay to Colombo for

8370-473: Was seen by the Japanese; Hiryu received a report of the encounter at 06:45. The strike group approached Colombo from the sea to the south-east; this course prevented detection by coast watchers and the 803 NAS line patrol. AMES 254 and its radar also failed to detect or report the inbound strike. British fighter pilots waited for a scramble order that, due to the lack of early warning, never came. Instead they were forced take-off under fire, instead of starting

8463-453: Was simply protecting its own economic interests. However militarists in the Japanese Army began pushing for an expansion of influence, leading to the Japanese Army assassinating the warlord of Manchuria, Zhang Zuolin . This was done with hopes that it would start a crisis that would allow Japan to expand their power and influence in the region. When this was not as successful as they desired, Japan then decided to invade Manchuria outright after

8556-457: Was so long that the passengers saw the sun rise twice, and it came to be called the 'flight of The Double Sunrise '. The first flight arrived from Perth on 30 March 1943; the last flight was on 18 July 1945. The service was later taken over by QEA (now Qantas) and Imperial Airways with the Catalinas replaced by civilianised Consolidated B-24 Liberator and Avro Lancastrian aeroplanes. After

8649-425: Was used by Japan, as neither country had made a formal declaration of war . From the Japanese perspective, localizing these conflicts was beneficial in preventing intervention from other countries, particularly the United Kingdom and the United States, which were its primary source of petroleum and steel respectively. A formal expression of these conflicts would potentially lead to an American embargo in accordance with
