The jaunt was headed by maritime archeologist Dominic Bush , who had been planning to search for the lost ship for the secure part of four eld . This summertime , he and 13 other researcher were finally able-bodied to follow through on those architectural plan , with a slim windowpane of just five days to carry out their employment .

gratefully , Bush and his colleagues ’ sashay raise fruitful . They found three sunken ship on the seafloor , which they documented with Department of State - of - the - artistry equipment .

The two Japanese ship unveil during this sashay were sunk by bombs from American aircraft after Japanese troops invaded the island of Attu in June 1942 . That intrusion , which took stead just about six months afterPearl Harbor , was at long last unsuccessful for the Japanese , as American troops hold in stopping them .
The one American ship that was discovered during this late expedition lapse around a calendar month after the Nipponese invasion was thwarted in May 1943 , when efforts were being made to reinforce the island ’s defenses .

“ This is n’t just an American story , this is n’t just a Japanese chronicle . It ’s a shared story . We ’re hope that archaeology can heal some of those divides , ” Bush order .
This conflict , which call down on for three bloody weeks that May , is often eclipsed in the history books by many other battle from the Pacific Theater , despite being the only battle in World War II to be fought in North America . In aggregate , 549 American service member perished , alongside 2,351 Japanese flock .
“ The original [ Japanese ] thought was to plow Attu into an ‘ unsinkable aircraft carrier , ' ” Bush toldLive Science . By establishing a presence in Alaska , the Japanese would then be able to apply this location to launch tone-beginning on other American locating .

“ But as thing originate to deepen in the Pacific , they were abandoned by the Imperial statement and fundamentally told to view as out for as long as they could — fundamentally , to perish with honor , ” Bush tote up .
The Story Of World War II’s “Forgotten Battle” Of Attu

Attu Island was occupied by Japanese forces in June 1942 , following theBattle of Midway . The occupation of Attu and nearby Kiska was part of Japan ’s broader strategy to divert American force and establish a defensive margin in the Pacific . The harsh , remote surround of the Aleutians made it a difficult theatre for military operations , lead to the struggle ’s obscurity in the chronicle playscript .
“ This was n’t just a little side banknote to the bigger Pacific hunting expedition . This was its own theater of warfare , the North Pacific dramatic art of war , which has for the most part been forgotten , ” Bush say .
The U.S. military , recognise the strategical importance of the Aleutians , plunge Operation Landcrab to reclaim Attu . The struggle was characterise by unrelenting conditions : freeze temperatures , fog , and rugged terrain . American personnel , numbering around 15,000 , face stiff impedance from close to 2,600 Japanese soldier entrenched in the mountains .
The Japanese military unit , commanded by Colonel Yasuyo Yamasaki , struggle ferociously , using the terrain to their vantage . The battle was score by acute hand - to - bridge player combat , artillery bombardment , and hard supply lines .
On May 29 , present impending defeat , Yamasaki led a last , dire banzai charge , which disclose through American lines before being repelled . The charge resulted in threatening casualties on both sides .
By the remainder of the battle , nearly all of the Japanese soldier were killed , with only 28 taken prisoner . The American forces suffered more than 3,800 casualties , including more than 500 dead . The victory at Attu was crucial for the Allies , as it slay the Japanese threat from the Aleutians and allowed the U.S. to focus on the central Pacific safari .
However , the battle remains overshadowed by larger engagement in thePacific Theater , earning it the moniker “ The Forgotten Battle . ”

Researchers said they have no plans to recover any fabric from the wreck . However , they are working with members of the Japanese government to figure out next stair for potentially repatriating any corpse at the land site .
Bush total that the announcement of this breakthrough will hopefully shine more light on this pivotal , often overlooked struggle — as well as another primal constituent of this chapter in history : the remotion and internment of the Unangax people who lived on Attu before the Nipponese invasion .
After the invasion , 42 Unangan Alaskans were get to Japan as prisoner of warfare , and many of their homes and small town were destroy . Half of those POW died from disease and malnutrition . Although the survivors come back to Alaska upon being freed , they did not really turn back to their home island .
“ We ’re really hear to bring tending to it , ” Bush said , “ both from the military perspective and from the Native perspective . ”
