TheBattle of Christmas Island was a small engagement which began on 31 March 1942, duringWorld War II. Assisted by amutiny of soldiers of theBritish Indian Army against theirBritish officers,Imperial Japanese Army troops were able to occupyChristmas Island without any land-based resistance. TheUnited States Navy submarineSeawolf caused severe damage to theImperial Japanese Navy cruiserNaka during the landings.
At the time,Christmas Island was a British possession under administrative control of theStraits Settlement, situated 161 nmi (185 mi; 298 km) south ofJava. It was a good control post for the east Indian Ocean and it was an important source ofphosphates,[1] which were needed by Japanese industry. Since 1900, the island had been mined for its phosphate, and at the time of the battle there was a large labour force, consisting of 1,000Chinese andMalays working under the supervision of a small group of British overseers. In addition, there were about 100 women and 200 children on the island.[2]
After theoccupation of Java, JapaneseImperial General Headquarters issued orders for "Operation X" (the invasion and occupation of Christmas Island) on 14 March 1942.[1]Rear AdmiralShōji Nishimura was assigned to command the Second Southern Expeditionary Fleet's occupation force, with thelight cruiserNaka as hisflagship. The fleet also consisted of the light cruisersNagara andNatori, anddestroyersMinegumo,Natsugumo,Amatsukaze,Hatsukaze,Satsuki,Minazuki,Fumizuki andNagatsuki, oilerAkebono Maru and transportsKimishima Maru andKumagawa Maru, with 850 men of the 21st and 24thspecial base forces and the 102nd Construction Unit.[1]
Opposing this invasion force was a single 6 in (150 mm) gun that had been built in 1900 and had been mounted on Christmas Island in 1940. The British garrison—a detachment of the Hong Kong and Singapore Royal Artillery—numbered 32 troops. It was led by a British officer, Captain L. W. T. Williams. Williams' force consisted of an Indian officer,Subadar Muzaffar Khan; 27Punjabi Indian gunners andnon-commissioned officers (NCOs); and four Britishenlisted men.[3]
A group of Punjabi troops, apparently believingJapanese propaganda concerning the liberation of India from British rule, and probably acting with the tacit support of some or all of the localSikh police officers, mutinied. On 11 March, they shot and killed Williams and the four British enlisted men – Sergeants Giles and Cross and Gunners Thurgood and Tate – and tossed their bodies into the sea.[3] They then locked up the district officer and the few other European inhabitants of the island pending an execution that apparently was thwarted by the Japanese occupation.[1][4]
At dawn on 31 March 1942, a dozen Japanese bombers launched the attack, destroying the radio station. The mutineers signalled their intention to surrender, raising awhite flag before the 850-man landing force had come ashore.[1] The Japanese expeditionary corps was able to disembark atFlying Fish Cove without opposition.[2][5]
At 09:49 the same morning, theUS Navy submarineUSS Seawolf fired four torpedoes at theNaka; all missed.Seawolf attacked again at 06:50 the following morning, firing three torpedoes atNatori, missing again. That evening, with her final two torpedoes, from 1,100 yd (1,000 m),[6]Seawolf managed to hitNaka on her starboard side, near her No. 1 boiler.[7] The damage was severe enough thatNaka had to be towed back to Singapore byNatori, and eventually was forced to return to Japan for a year of repairs. Following the hit, the other Japanese vesselsdepth charged the US submarine for over nine hours but it escaped.[8]
Natori returned to Christmas Island and withdrew all elements of the occupation force, with the exception of a 20-man garrison detachment, toBanten Bay, Indonesia, on 3 April 1942. The Japanese gainedphosphate rock which was loaded on the transport ships.[1]
Following the occupation, the Japanese garrison attempted to put the Chinese and Malays to work, although many escaped further inland to live off the land. The mutineers also became labourers, being employed to clean storage bins.[2] Production was only very limited after the occupation and after the 17 November 1942 sinking of theNissei Maru by the submarineUSS Searaven[9] while unloading at the wharf, phosphate production was halted altogether. Over 60 percent of the island's population, including the European prisoners, were relocated to Java by December 1943. After the war, Christmas Island was reoccupied by the UK in mid-October 1945.[2]
In the post war period, seven Punjabi mutineers were traced and court-martialled in Singapore. The first six to be identified and tried were convicted on 13 March 1947. Five were sentenced to death, and one was sentenced to two years' imprisonment and discharge with ignominy. KingGeorge VI confirmed the death sentences on 13 August 1947. British rule in Indiaended shortly afterward, with India gaining independence andPakistan being created before the executions could be carried out, and thus diplomatic issues had to be taken into account. In October 1947, a seventh mutineer was identified. He was also court-martialled and sentenced to death. An eighth soldier was identified as a participant in the mutiny but was never caught. On 8 December 1947, the death sentences were commuted to penal servitude for life after the governments of India and Pakistan made representations. After further arguments between the UK and Pakistan over where the sentences should be served, with the British demanding they serve nine years, the six prisoners were transferred to Pakistan in June 1955, after which the British government ended its interest in the case.[1][3]
