Sulfureous island is the volcanic island that after on Pacific Ocean one is cooled by volcanic lava, forms, landform rises and fall, gully freely, cliff faces the sea to tower. Have kilometer of 20 more than square only, north is strewn at random fluctuant upland, form by a series of small hillock and abrupt gorge. Hill hillock tall Cheng is controlled 100 meters mostly, landform is complex, but volt a large number of forces. Southern relief is low smooth, have the beach that one flake is forced by ladder shape mesa, can make constrainedly land. Divide this beyond, complete island does not have any berth that can offer shipping berth or harbour. Although sulfureous island is bullet isle, lie however strategic fastness. It just when Tokyo and U.S. Army are new between island of occupational class of a place of strategic importance, be apart from 2 ground to make an appointment with 1200 kilometers each. The U.S. Army is occupational after island of class of a place of strategic importance, it is Tokyo of base air attack with island of class of a place of strategic importance all the time. But because of sulfureous island call the police action, the U.S. Army is right the air attack of Tokyo all the time the effect not beautiful. The Japanese army battleplan that is stationed in sulfureous island often still enters the space intercept, a group of planes of break up United States. For general attack Japan, u.S. Army certainly will should be seized take sulfureous island. And for Tokyo safety, the Japanese army also certainly will wants defend to the last sulfureous island. Result, this untrodden small volcanic island, in later period of Pacific Ocean war, the land that makes day of beauty be contended for surely...
Since the U.S. Army razziaed in July 1944 after the Mariana, begin to build aviation base, dispatch B, Japan of air attack of 29 heavy-duty bomber is native land. But the Mariana is apart from Japanese mainland near 1500 sea mile, b, the 29 air attack that have such Sunday run, because accept the restriction of range, can carry 3 tons of bomb only, it is B only, 30% of 29 the biggest bomb load. And because range is too long, battleplan cannot undertake whole journey convoy, because of this B, 29 can be in 8000 carry out area bomb to 9000 meters of height, the effect very not ideal.
Tokyo of sulfureous island northing 650 sea mile, the island of class of a place of strategic importance that the Mariana is apart from south 630 sea mile, lying almost of two ground among, the Japanese army on the island can offer inchoate early-warning to Tokyo not only, and can take off battleplan undertakes intercept, still dispatch ceaselessly even plane attack U.S. Army is in the airport of and other places of island of class of a place of strategic importance, was to reduce an U.S. Army greatly more the action of bomb of native land to Japan strategy. Sulfureous island is right the U.S. Army, if fishbone,be simply in larynx. If the U.S. Army is occupational sulfureous island, that all adverse translate into is advantageous, from sulfureous island takeoff B, 29 range reduce an in part, bomb load can increase one times; If battleplan takes off from sulfureous island, can be B, 29 offer whole journey to accompany convoy; Connect B even, such 24 medium-sized bomber also can take off from sulfureous island air attack Japan is native land; More important is sulfureous island still can serve as B, the equipment of 29 falls the airport, for wounded B, 29 crash-land or cheer. Accordingly the U.S. Army is to sulfureous island situation in must! Beautiful army air arm (namely the predecessor of air force) admiral of commander Arnaud put forward to razzia to joint meeting of beautiful chief of staff on April 17, 1944 the request of sulfureous island, immediately of joint meeting of beautiful chief of staff agrees with this one request, enjoin Pacific Ocean war zone loads this to fight, commander-in-chief of Pacific Ocean war zone holds admiral of Nimitz of commander-in-chief of Pacific Ocean fleet concurrently to be directed for nearby, its headquarters moves from Pearl Harbor to Guam.
At the beginning of October 1944, the give advice personnel of ministry of Pacific Ocean admiral makes the plan that attacks sulfureous island come out, attend the ground armed forces that fight to be the 5th amphibious army, marine Corps issueing administer the 3rd, 4, 5 division, make an appointment with 60 thousand person in all, by direct of lieutenant general of suddenly Lan Smith; Land form into columns and assist form into columns, by direct of lieutenant general of Kaili Tena; Commanding of Miqieer lieutenant general the 58th mix especially form into columns responsible sea air is covering; All attending a war landing boat a light boat makes an appointment with 500, the warship makes an appointment with 400, the plane makes an appointment with 2000, by the 5th admiral Sipuluensi admiral unites direct.
Because attend a war,the part comparatives to be in those who assist pair of Luzon to land in army fight, sulfureous island battle is obliged to wait for Luzon battle to just can begin after the end in January 1945, make progress because of Luzon battle again slow, the date of the end from the plan on December 20, 1944 remit to on January 9, 1945, nimitz again of will sulfureous island fight remit to in Feburary 1945 the middle ten days of a month.
Sulfureous island, be located in south of former archipelago of small large bamboo hat, it is the 2nd big island of this archipelago, northing Tokyo 1200 more than kilometer () of 650 sea mile, island of class of a place of strategic importance is apart from south 1100 more than kilometer () of 630 sea mile, the Mariana is apart from southeast 500 more than kilometer () of 290 sea mile. The island is about 8000 meters long, about 4000 meters wide, appearance is exactly like ham, the area makes an appointment with 20 square kilometer, insular south has an extinct volcano that has not cool completely, make fold earthen bowl hill, altitude 160 meters, all the year round is erupting mirage, sulfureous flavour diffuses complete island, this gets friend renown. The hill that fold earthen bowl has the raise of a broader level off with north, call mid upland, go to again north, landform rises and fall gradually, and know exactly about sth mountain peak, be called yuan of country region, major area is enclothing deep eruption on the island. Although a mean person of sulfureous island island is little, but lying between Tokyo and island of class of a place of strategic importance, strategic position is very significant.
Before 1944, the Japanese army regards Pacific Ocean as sulfureous island merely mid the aviation relay base with the south, deploy naval fielding army Yu Ren and 1500 planes 20. 1944 after Mariana fall, the value of sulfureous island is overt with each passing day, the Japanese army just begins to enhance its defense power energetically, the last ten-day of a month served an island troop of 4000 more than army in March; The army troops reorganize of will sulfureous in May island is the 109th division, lieutenant general of the path in You Sulin holds the post of division colonel, deployed on the island 120, ack-ack of big gun of 155 millimeter shore, 100 millimeter and double couplet hold 25 millimeter antiaircraft gun; Group of battle of the 27th aviation also moved navy to the island to go up in July. End Feburary 1945, the Japanese army is made an appointment with in the army on the island 15 thousand beyond, navy is made an appointment with 7000 beyond, make an appointment with 23 thousand person in all, plane more than 30, you Sulin unites direct. The Japanese army is mixed in the mid upland on the island each build yuan of country division have an airport, call 1000 islands the airport respectively mix yuan of hill airport, also call an airport and 2 airports, build the 3rd airport with north in 2 airports. Razziaed quickly as a result of the U.S. Army Mariana, original plan fate is turned to be used at sulfureous island by nearby toward the personnel of the Mariana, equipment and goods and materials, although the U.S. Army organizes plane, submarine to hit out with all one's strength, the purpose cuts off the reinforce of sulfureous island and supply, but the Japanese army is terminal with father island, take the kind of cockboat lighterage, block effect of the U.S. Army is not accordingly ideal.
Annihilative blow sufferred in Philippine battle as a result of the brunt of sea air force of the Japanese army, already offerred sea air to assist for sulfureous island feebly, of sulfureous island fight land fighting is to should be below the case that helps without sea air almost undertake. Su Lin is splendid professional soldier, ever had held the position of the commander of army of guard of the emperor of Japan, he realizes face an U.S. Army absolutely sea vacant dominant position, beach head fights hard be successful, the view is mixed by right of the hill that fold earthen bowl the advantageous landform of yuan of hill country, rely on solid defence works, executive depth defence. But naval fielding army still holds to annihilate enemy at beach head, final Su Lin made eclectic plan, give priority to with depth defence, beach head defence is complementary, coastal beach builds naval fielding army to always shoot dot and strong strong point fully, have defence; Army main force is mixed in the hill that fold earthen bowl centrally yuan of country region, executive depth defence.
Su Lin is determined to build sulfureous island solid fortress, it is core position in order to fold earthen bowl hill, it is main defense region with two airports, the thing beach that landing aptly is the defense position that is a backbone with always shooting dot and strong strong point fully, the fortification of the Japanese army is given priority to with subterranean sap position more, concrete defence works and natural grotto organic union, traffic fosse joins each other. Artillerist position also builds half underground pattern mostly, although sacrificed area of fire, rose to issue viability in violent bombard greatly however. Artillery and communication network get good protection, the hill that fold earthen bowl is drawn out almost empty, build some tunnel with respect to 9! Those who be aimed at an U.S. Army fight characteristic, su Lin is buried in beach depth set abundantly thunder, machine gun, trench mortar, Piat makes continous close fire net, the configuration of all weapons and fire cause had undertaken mathematical calculation, can concealment already oneself, can utmost kills and wound enemy. What be not worth exclusively is, plan yuan of mountain area to the tunnel defence works of build the tunnel defence works of build grows 28 kilometers formerly, because time is insufficient, finished only when the U.S. Army launchs attack 70% , make an appointment with 18 kilometers, and the hill that fold earthen bowl and yuan also join without tunnel between hill.
Su Lin changes the Japanese army to die earlierly in the war spell tactics, set be apart from defence of motor-driven of fire, divide forces nearly, lure the tactics such as volt, return forbidden suicide charge, each soldier should kill the appeal at least 10 U.S. Armies. These elaboration of Su Lin, caused tremendous difficulty to the U.S. Army really, make the battle of sulfureous island becomes Pacific Ocean to go up the brutallest, arduous land battle...
