二战期间，所有在被盟军绕过的岛屿上的日本士兵发生了什么？他们都饿死了吗？如果他们幸存下来，他们在战争结束后被遣返了吗？

 二战期间，所有在被盟军绕过的岛屿上的日本士兵发生了什么？他们都饿死了吗？如果他们幸存下来，他们在战争结束后被遣返了吗？

马克-皮蒂的《南洋，日本人在密克罗尼西亚的兴衰》一书在一定程度上探讨了这个问题。在日本驻军（通常由日本平民定居者以及军人组成）被绕过马绍尔群岛、吉尔伯特群岛、卡罗琳群岛、马里亚纳群岛、所罗门群岛和其他地方的各个岛屿后，日本帝国海军试图通过潜艇或水上飞机为他们补给一段时间，但最终无法维持供应任务。

盟军通过频繁的空中轰炸，有时通过水面舰艇的轰炸，对各个被绕过的驻军保持压力。面对饥饿，被绕过的驻军依靠当地的食物，包括椰子、面包果和本地鱼。在某些情况下，孤立的日本驻军完全耗尽了他们所占领的环礁上的鱼群。在一些岛屿上，日本人试图耕种和收获他们自己的农场，结果好坏参半。有几起从被击落的轰炸机上吃盟军战俘的事件，日本人有时可能会吃掉死于饥饿或疾病的战友。说到疾病，在卡罗莱纳群岛的萨塔万岛的驻军被当地一种类似跳蚤的昆虫侵袭，在日本投降后被盟军当局解救之前，这给他们带来了强烈的痛苦和折磨。投降后，幸存的日本军舰和商船被派去执行任务，将岛上的驻军遣送回日本。

附录：我终于找回了我的《南洋》，这里有一些关于密克罗尼西亚被绕过的日本驻军的更多细节。请记住，在密克罗尼西亚以外的荷属东印度群岛、所罗门群岛、海洋岛、瑙鲁和其他地方也有其他被绕过的驻军。

马绍尔群岛--被绕过的驻军有沃特吉（战争结束时，原有的3000名驻军中有1000名幸存者）、贾鲁特、米利（4700名驻军中有1900名死亡）和马洛拉普（原有3000名驻军中有2000名死亡）。

卡罗琳群岛--被绕过的驻军有：波纳佩（由于农业丰富，8,000名军人和5,700名平民定居者幸存下来，损失不大）、特鲁克（38,000名平民和军人；死亡人数不详）、库萨伊（300人死于饥饿）、沃莱伊（原7000名驻军中有1600人幸存）、普鲁瓦、雅浦、莫洛克（诺莫里）和萨塔万。

帕劳--艾梅利克和巴贝尔图普（2000人死亡）已经绕过了驻军。

马里亚纳群岛--罗塔、帕甘和阿吉关有小规模的、被绕过的驻军。

最初（1944年），在上述被绕过的密克罗尼西亚驻军中，仍有6万名日本陆军和海军部队。战争结束后，共有95,000名军人和52,000名平民从太平洋各地（不包括亚洲大陆）被遣送回日本、朝鲜和台湾。

What happened to all the Japanese soldiers who were on islands that were bypassed by the Allies during WWII? Did they all starve? Did they get repatriated at the end of the war if they survived?

The book "Nanyo, the Rise and Fall of the Japanese in Micronesia" by Mark Peattie goes into this to some extent. After Japanese garrisons, often consisting of Japanese civilian settlers as well as military, were bypassed on various islands in the Marshalls, Gilberts, Carolines, Marianas, Solomons, and other places, the Imperial Japanese Navy attempted to keep them resupplied by submarine or seaplane for awhile, but eventually was unable to keep up the supply missions.

The Allies kept pressure on the various bypassed garrisons with frequent aerial bombing and sometimes bombardment by surface ships. Faced with starvation, the bypassed garrisons depended on local foods including coconuts, breadfruit, and native fish. In some cases, the isolated Japanese garrisons completely depleted the fish population in the lagoons of the atolls they were occupying. On some islands the Japanese attempted to cultivate and harvest their own farms, with mixed results. There were a few instances of cannibalism of Allied prisoners of war from shot-down bombers and the Japanese may have sometimes cannibalized their comrades who died of starvation or disease. Speaking of disease, the garrison on Satawan in the Carolines was overrun by an infestation of a local chigger-like insect, which caused them intense pain and suffering before they were rescued by Allied authorities after Japan's surrender. After the surrender, surviving Japanese warships and merchant ships were impressed into duty to repatriate the island garrisons back to Japan.

Addendum: I finally retrieved my copy of “Nanyo” and here are some more details on bypassed Japanese garrisons in Micronesia. Keep in mind that there were other bypassed garrisons outside Micronesia in the Dutch East Indies, Solomons, Ocean Island, Nauru, and other places.

Marshalls- Bypassed garrisons on Wotje (1,000 survivors of original 3,000 in garrison at war’s end), Jaluit, Mili (1,900 died out of a garrison of 4,700), and Maloelap (2,000 died of original 3,000 garrison).

Carolines- Bypassed garrisons were on Ponape (8,000 military and 5,700 civilian settlers survived with few losses due to abundant agriculture), Truk (38,000 civilians and military; unknown number died), Kusaie (300 deaths from starvation), Woleai (1,600 survivors from original 7,000 garrison), Puluwat, Yap, Morlocks (Nomori), and Satawan

Palau- Aimeliik and Babelthuap (2,000 deaths) had bypassed garrisons

Marianans- Rota, Pagan, and Aguiguan had small, bypassed garrisons

Initially (1944), there remained 60,000 Japanese army and navy troops on the bypassed Micronesian garrisons listed above. A total of 95,000 military and 52,000 civilians were repatriated to Japan, Korea, and Taiwan from all parts of the Pacific ocean (excluding mainland Asia) after the war ended.
