- Easter Sunday Raid
The Easter Sunday Raid was an air raid carried out by the
Empire of Japan onEaster Sunday ,5 April ,1942 onColombo ,Ceylon (now Sri Lanka), as a part of theIndian Ocean Raid . A few days laterTrincomalee was also attacked. The raids were intended to disrupt the war effort of British Commonwealth nations and force theBritish Eastern Fleet to leaveAsia n waters.Background
The British had been in occupation of the coastal areas of the island since 1796, but the colony had not had a regular garrison of British troops since 1917. The
Ceylon Defence Force and Ceylon Navy Volunteer Reserve were mobilized and expanded. TheRoyal Navy maintained naval installations inTrincomalee and theRAF had established an aerodrome in China Bay, Trincomalee long before the war.After the
fall of Singapore theRoyal Navy 'sEast Indies Station was moved toColombo and then toTrincomalee .Admiral Sir Geoffrey Layton was appointed Commander-in-Chief, Ceylon withAir Vice Marshal John D'Albaic as Air Officer Commanding andAdmiral Sir James Somerville appointed commander of theBritish Eastern Fleet .The fixed land defences consisted of four
coastal batteries at Colombo and five at Trincomalee; these were established just before the war. Air defences were expanded in 1941 with theRAF occupying the civil airfield at Ratmalana near Colombo with its station headquarters set up atKandawala . Another airbase was rapidly built at Koggala nearGalle and several temporary airstrips were built across the country with the largest at Colombo Racecourse grounds. Several RAFsquadrons were sent to Ceylon.The attack
With
Japan 's entry into the war, and especially after the fall ofSingapore ,Ceylon became a front-line British base against the Japanese. Admiral SirGeoffrey Layton was appointed Commander-in-Chief, Ceylon. Air Vice MarshalJohn D'Albaic became Air Officer Commanding. Admiral Sir James Somerville was appointed commander of theBritish Eastern Fleet . Somerville retreated with his main fleet toAddu Atoll in theMaldives , leaving theaircraft carrier "Hermes", escorted by the heavy cruisers "Cornwall" and "Dorsetshire", and theRoyal Australian Navy destroyer HMAS "Vampire" in Ceylon.After the
sinking of Prince of Wales and Repulse and thefall of Singapore , British morale on the island dropped. The sinking of these two capital ships shocked much of the world; the awareness of the superiority of aircraft carriers over battleships increased dramatically. On Ceylon there was understandably much anxiety that a Japanese attack appeared to be inevitable. A largesea turtle which came ashore was reported by anAustralian unit as a number of Japaneseamphibious vehicle s. However, actual preparations for defence were lackadaisical, apart from the deployment of aRoyal Air Force squadron at the Colombo race course. Anti-British sentiment increased accordingly within some portions of the indigenous population and their hopes ran high for liberation by the Japanese.On
4 April 1942 the Japanese Navy fleet of AdmiralChuichi Nagumo was located by a Catalina aircraft flown by Squadron LeaderLeonard Birchall out of Koggala. However, Nagumo achieved near-complete surprise when he launched an airstrike on Colombo the next day (Easter Sunday ,5 April ). Despite the fact that the war in Europe had been raging for almost 18 months, and in the Pacific for almost four, the British radars were not operating because it was Sunday.But the greatest shock of the day was probably felt by the Japanese high command, who had expected to catch the remnants of the British fleet at anchor in Ceylon. The Japanese had planned the bombing of the Eastern Fleet's home base with meticulous care and precision in a manner almost exactly like the Pearl Harbor operation (in fact many of the same bombers with the same pilots participated in both strikes). Most of the British Eastern Fleet was maintaining radio silence in Addu Atoll, so that when the Japanese arrived at Colombo there were only three ships at anchor instead of the much larger number they had anticipated.
The continued existence of the remnants of the British Eastern Fleet (which included some Dutch warships as well) prevented the Japanese from attempting a major troop landing in Ceylon. Speaking at a dinner party at the British Embassy in Washington after the war,
Winston Churchill called the attempted invasion of Ceylon, “the most dangerous moment of World War II.” Churchill concluded that if the Japanese fleet had succeeded, they would have controlled the Indian Ocean.The
Hawker Hurricane s of No 30 Squadron were on the ground at Ratmalana when the Japanese aircraft passed overhead. Theauxiliary cruiser "Hector" and the old destroyer "Tenedos" were sunk in the harbour. The Japanese discovered the "Cornwall" and "Dorsetshire" 320 km (200mile s) southwest of Ceylon and sank the two ships. British losses were 424 men killed; 1,120 survivors spent hours in the water. The RAF and theFleet Air Arm (FAA) lost at least 27 aircraft, the Japanese only five. The Japanese also bombed the lunatic asylum at Angoda, mistaking it for the fuel tanks at nearby Kolonnawa.On
9 April 1942 the Japanese attacked the harbour at Trincomalee and the British ships offBatticaloa . "Hermes", "Vampire" and theFlower-class corvette "Hollyhock" were sunk. TheRoyal Air Force lost at least eight Hurricanes and the FAA oneFairey Fulmar . The Japanese lost five bombers and six fighters, one in a suicide attack on the Trincomalee fuel tanks.The sortie demonstrated Japanese superiority in carrier operations. Good luck favored Somerville when the Japanese did not find his fast carriers "Indomitable" and "Formidable"; these ships were saved to fight another day. But British prestige was brought even lower than it had been after the fall of Singapore.
