Drake, French Indochina, and Tokyo Rose

As September ends and the richness of fall is upon us, we should reflect on events on 26 September that have nearly nothing to do with the season–or not.  But the completion of Drake’s circumnavigation, the Japanese occupation of French Indochina, and the death of Francis Aquino all happened on 26 September, with a half millennia or so separation.

On 26 September 1580, Frances Drake, a career navigator, scoundrel, pirate, politician and seaman sailed his 300 ton galleon Golden Hind into Plymouth harbor in southern England, completing the first circumnavigation of the world as captain, and the second ever (Magellan died on his voyage).  Elizabeth I knighted him soon thereafter.  What was most extraordinary about the voyage wasn’t the three years it took to complete, or the six tons of Spanish gold she captured, but that it was completed with a crew that was half of what he started out with. Drake’s circumnavigation, though mostly a military expedition, was also the first time a English ship had crossed the Pacific Ocean, and may have been the first time that an Englishman saw Indonesia.

What was most extraordinary about the voyage … that it was completed with a crew that was half of what he started out with.

Since the beginning of the “China Incident” in 1937, the Vietnamese port of Haiphong in French Indochina (northern Vietnam) had been one of several ports used by China to receive arms shipments (until 1939, China’s was Germany’s best arms customer), and was an important source of foreign currency for the cash-strapped Vichy French government in Hanoi. After several months of dithering, the Japanese finally got around to moving into French Indochina and, later, what was then Cochinchina (southern Vietnam) on 26 September 1940, after weeks of unsuccessfully negotiating with the Vichy into allowing some sort of “guest” occupation.  The Japanese occupation of French Indochina was the last straw for the Roosevelt administration, which moved to embargo oil, scrap metals, and Japanese funds in American banks.  This embargo was one of the driving forces behind Japan’s attacks on American, British and Dutch holdings in East Asia beginning in December, 1941.

The Japanese occupation of French Indochina was the last straw for the Roosevelt administration

“Tokyo Rose” was the nickname for several female English-language, American-vernacular Japanese propaganda broadcasters during World War II.  The best known announcer was Iva Toguri D’Aquino, a native American caught in Japan at the outset of the war.  Broadcasting her ten to fifteen minute harangue (sometimes accurately naming units, commanders and even enlisted men and their stations) during the Zero Hour program of popular American music, most regarded her broadcasts as harmless, and for the most part useless as an anti-morale weapon.  Though cleared of war crimes in Japan, she was tried and found guilty of treason in 1949 when she returned to the United States.  Released in 1956, she was eventually pardoned in 1977 by Gerald Ford. D’aquino died in Chicago on 26 September, 2006.

 Broadcasting … during the Zero Hour program of popular American music, most regarded her broadcasts as harmless, and … useless as an anti-morale weapon.

From Drake’s epic 16th century expedition to the death of Tokyo Rose in the early 21st, East Asia, Europe and the Pacific have been tied to 26 September, and to many other dates.  Though D’aquino was largely a victim of circumstance, so too was French Indochina, caught as she was in between quarreling giants in a conflict not of her making.  Drake’s ship, one of the first ever to be put on public display, gradually rotted into destruction, and two replicas have also been lost over the years.  Tokyo Rose, too, had copies, like Pyongyang Sally during the 1950-53 war in Korea, and Hanoi Hanna during the American involvement in Vietnam.  The threads of human events are often interwoven in common calendar dates.  We’ll continue to explore this line of thought next week.




20 November: Cambrai and Tarawa

As a matter of perspective, these two battles shouldn’t even be in the same century.  The British attack on the German positions in front of  Cambrai  in norther France were a part of a conflict that Tarawa could not seriously have been a part of, but the slaughter-fest of Tarawa was easily a throwback to the butchery of the Western Front of WWI.

By late 1917 the Allied planners were not only running out of men they were running out of generals willing to use their soldiers bodies as battering rams against each other.  1917 was a weak mirror of 1916’s horrific bloodletting on all fronts from Flanders to the Caucasus.  The French Army was on the verge of collapse, the British relying on Canadians and Australians to shore up their staggering troops, and the Americans were unwilling to do what they were supposed to do, which was to turn over their milk-and-beef-fed manpower to the French and British to shore up their bleeding divisions.

So the British turned to Winston Churchill’s “land battleships” that we now know as “tanks.”  They had nearly four hundred of the huge mechanical contraptions on hand, and thought that with creeping barrages, infiltrating infantry, close air-ground coordination and some good weather they might achieve a breakthrough that could seize the German supply hub at Cambrai, cutting off supply to the Hindenburg Line and displacing the whole of the German force in France.  Although this sounds a great deal like what the Germans would do six months later in the “Michael” offensive and beyond, the British had taken the same lessons from the success of the Huitier tactics first seen in Russia that the Germans who developed them had.

A generation later, the Americans were trying to decide the best way to grapple with the Japanese in the Pacific.  With New Guinea in hand, the Solomons more secure than they were, and the Japanese fleet unbalanced, the planners looked at the next step towards the prewar plan to blockade Japan prior to invasion.  They needed the Marshall Islands as bases, and from the Solomons and the Allied bases in New Zealand and French Polynesia, that meant they needed the Gilbert Islands.  The largest island in that chain was Betio, a part of the Tarawa atoll.

The Americans had spent much of the period between Versailles and Pearl Harbor thinking about how to cross a quarter of the world to bring Japan under its guns.  The US Marines were the US Navy’s base-grabbers, and the Marines had been built from the fire team level up to secure the bases needed to do that.  But like the large numbers of tanks at Cambrai, they had very little live experience at capturing hot beaches.  They had been blooded in the Solomons (where the landing was essentially unopposed) and at Makin (a raid), but their long training and many beach landings had not prepared them for an opposed landing.  They knew that the Gallipoli campaign was, to put it mildly, a negative example of what to do.   But, tactically, how this would work was still a theory.

Cambrai kicked off on 20 November 1917 with the British Third Army under Julian Byng barraging the German Second and Third Armies under Georg von der Marwitz in front of Cambrai, followed by a fraction (sources differ, but probably more than  400) of the tanks that made it to the front and their accompanying infantry.  Though the Germans were ready and had some antitank weapons the sheer number was a problem, even if the early machines were more likely to simply break down than be knocked out by enemy action.  The result was an unexpectedly spectacular British success in some places, unexpected failure in others.

At Tarawa, success was a matter of staying alive.  By the time the Marines stormed ashore on 20 November 1943 the Americas had pounded the two mile by 800 yard coral rock with more ordnance in three days than the Americans used in their civil war.  As the landing craft carrying Julian Smith’s 2nd Marine Division approached the beaches they grounded, often as not, on  coral reefs that hadn’t been accounted for in pre-battle planning.  No one had expected that around that blasted coral rock, oceanographers would first discover the maximum neep tide that would only occur about twice a year, and not everywhere at the same time.  But the landing craft grounded on the reefs that were supposed to be underwater a hundred yards or so from the beach, the ramps would drop, and the Marines would step out into the water often over their heads, and the lucky ones would merely drown.  Many of the rest would be shredded by the Japanese of Keiji Shibazaki’s garrison’s automatic weapons and artillery, which were quite unaffected by the American bombardment.  By dark on the first day the Marines were barely ashore, their casualties in some companies was more than 50%, and the Japanese just kept fighting.

Cambrai turned into a version of what had already happened over and again on the Western Front: attack, counter-attack, bombardment and repeat.  This went on until 7 December, and the territorial gains were minuscule compared to the human cost.  Both sides used the new infiltration tactics, but in the end the artillery dominated, as did exhaustion and a weariness of killing.  Very little changed for another eighty thousand casualties and a quarter of the tanks in the world.

On Tarawa, the slaughtering went on for three days.  The first use of what what would be called “corkscrew and blowtorch” tactics were used against Japanese strongpoints (essentially pinning the defenders down with automatic weapons fire so that flamethrowers could get close enough to be effective).  The Marines suffered some three thousand casualties with about half killed out of a 16,000 man division.  Of somewhat more than 4,600 Japanese defenders, all but 150 or so were killed.

Cambrai pointed the way to eventual success of armored thrusts and coordinated air/ground tactics, together with quick and intense artillery barrages that the Germans would use in 1918, and again in 1939.  Tarawa would point the way to Japanese destruction by isolation because death was their only option as long as they kept faith with the leadership in Tokyo.  It would also show the Americans that hot beaches would need somewhat more than raw courage to overcome.

The Madness of March for Japan

The last days of March have some special significance to Japan, for it was in March from 1854 to 1945, things seemed to go a little…mad.  And it all started, ironically, with a treaty.

On 21 March 1854, Matthew C. Perry secured the signature of the Tokugawa shogun of Japan on what was called the Treaty of Kanagawa, ensuring enduring peace, friendship and diplomatic ties.  While contemporary audiences may not think a great deal of that, it was shocking to Japan.  Traditionally, Japan was a closed-off, secluded place, with a single paved road, a few wheeled carts, no seagoing ships to speak of, and a dominant, militaristic social group–the samurai–that made 19th century Prussian militarists seem like pacifists.  For centuries they had imprisoned or simply murdered shipwrecked sailors, and for two hundred years they had but one trading outlet on Kagoshima Island in Nagasaki harbor.

But then came Perry, and Perry came because the Americans, sharing Pacific Rim status after their purchase of California from Mexico (at gunpoint, but purchased nonetheless), were concerned about their whaling and trading fleet.  More than one shipwrecked Yankee had been hanged or crucified in Japan.  Further, the growing Russian presence in the Pacific was of some mild concern, as were the Russian trading posts in Alaska, along the Canadian Pacific coast, and the growing British bases in Hong Kong and Hawaii–then the Sandwich Islands.  The growing United States needed some assurances that American trade with China–America’s oldest trading partner–was safe from predation.

But societies are closed for a reason, and the reasons Japan was closed from 1635 up to the mid-19th century are somewhat complex, but they usually begin and end with the Japanese concepts of cultural and racial purity, and of the supremacy of Japanese exceptionalism.  These concepts were enforced at the point of the sword by the samurai, who had dominated Japanese society since anyone could remember.

In practice, Japanese society was stratified into three layers.  The nobility, notably the Emperor and his family, but also other petty nobles (daimyos) who had little function other than to provide brides (and the occasional groom) to the royal family, sat at the top.  Directly beneath them were the samurai, who had since time immemorial been providing a totem/warlord/top gang leader called a shogun, who enforced what little civil law there was but mostly just kept the peace.  In 1604, the Tokugawa clan took over the shogunate after a disastrous invasion of the Asian mainland that ended in 1600.  Beneath the samurai there was everyone else.  Social mobility was practically unheard of.

The shoguns may have ruled the country, but they were not the only ones who had, or craved, power.  Since the provincial warlords had a great deal of power themselves, rivals to the Tokugawas were numerous, and dangerous.  Japan’s polity was never inclusive: the bottom 90% existed to support the top 10%.  Peasant revolts–primarily over food– averaged two a year, and were always put down in oceans of blood.  When Ieyoshi signed the Kanagawa treaty, he was signing the death knell for Japan’s way of life.  Almost instantly rival clans claimed that the Tokugawa shogun, whose duty it was to keep the long-nosed barbarians away from the emperor  and the islands of Japan, had betrayed his duty.

Within two years, Japan was in civil war along the length and breadth of the archipelago.  There were two factions: the one that favored Western contacts and expanded trade–generally aligned with the Tokugawas–and those who did not.  Ironically, it was the samurai that did not favor expansion of trade who modernized first, adapting western firearms and artillery.  By 1867 the Meiji Emperor proclaimed the end of the samurai tradition…which in fact only meant the end of Japan’s social structure.  While Japan modernized its industry and economy, its society was left to itself.  The result was, eventually, a polity that regarded China as a resource-rich wilderness infested with vermin–the Chinese–that would have to be subjugated so that the 70 Million (as the Japanese began to refer to themselves) could take what they needed.  On 27 March 1938, one of the most ferocious battles of that subjugation began at Taierzhuang (or Shandong), on the eastern bank of the Grand Canal of China.  When the battle ended on 7 April, there were some 44,000 casualties, a ruined city, and a defeated Japanese host.

But Japan’s March Madness continued.  in the very early morning of 27 March 1943, two Japanese heavy cruisers, two light cruisers  and four destroyers commanded by Boshiro Hosogaya met a US Navy heavy cruiser , a light cruiser and four destroyers under Charles McMorris near the Komandorski Islands in the north Pacific.  After four confused hours the Japanese retired, not understanding how much damage they had done.  What might have been a Japanese victory turned into a strategic disaster, as it ended the surface resupply efforts for the Japanese garrisons in the Aleutians, leaving it to submarines and condemning many to starvation.  It was also one of the last daylight naval actions conducted without air power: in fact, it was Hosogaya’s fear of American air attacks that compelled him to pull out.

Two years later, as Iwo Jima was declared secure on 26 March 1945, the garrison on Okinawa grimly watched the huge Allied fleet gathering and bombarding offshore, and wondered when the madness would end.  On 1 April, the Americans landed on Okinawa, and the last stages of Japan’s Madness in March began.

When the Roof of Hell Opened Up and Tokyo Fell In

When they first heard of it, the men who had flown over St Nazaire and Brest, Schweinfurt and Munich, Ploesti and Wiener-Neustadt, Shanghai and Bangkok and lost a thousand friends in the high altitude combat boxes knew that it was a mistake.  The briefers misread it, they thought.  But no.  The B-29s of the XXI Bomber Command would bomb Tokyo at night, individually, in a continual stream of aircraft at altitudes from 6,000 to 12,000 feet.  There was no mistake.  Curtis Lemay, commanding the B-29s in the Marianas islands in early 1945, was in deadly earnest.

But there was a reason for it: many.  The air campaign against Japan had been disappointing.  The B-29 Superfortresses, the most advanced bombers in the world, the largest and the most powerful aircraft in the world, suffered from teething pains that included engine fires and electrical problems.  Some missions lost as many as 5% of their aircraft to these causes alone.  Added to this, weather over Japan was unexpectedly bad much of the time, even more unpredictable than northern Europe.  The discovery of the jet stream during the bombing missions of 1944 was a boon to the weathermen, but it wreaked havoc on bombing accuracy and on airplanes.

So the planners and the Boeing engineers added it all up and determined that the problem with the engines was uneven engine cooling; with the electrical system was instrument freezing; that with the weather was high-altitude flying.  The answer was to fly lower, which meant abandoning the box.  To accommodate that radical change, the missions would be flown at night, in part because the intelligence boys were saying that Japanese night fighter strength was negligible.

Then the issue became the nature of the target.  Japanese industry wasn’t concentrated in plants or even in small shops; while final assembly was centralized, the components were made in shops based in homes.  One in four Japanese homes had a machine tool or finishing station within the structure.  Many more had made piece-parts in outbuildings or in communal sheds.  Most Japanese cities were primarily made of paper and wood, especially the residential areas.  The insurance industry, performing studies of German and Japanese cities for the Army Air Force, reminded their audiences that massive fires were common in Japan.  In 1922 a fire had destroyed more than five square miles of Tokyo.

So the orders went out to the bases on Guam, Saipan and Tinian: the bombers would carry incendiary bombs only, would leave most of their defensive guns on the ground, and would attack individually from low altitude.  The bombers would launch at dusk on 9 March 1945: target, Tokyo.

Just after midnight the first pathfinders arrived over Tokyo, marking Incendiary Zone Number One, enclosing an area four by three miles with thermite and magnesium flares.  Then came the other bombers with their napalm and white phosphorus.  After fifteen minutes the water mains started to burst and after thirty minutes the electrical power went out. Two-thirds of the Tokyo Metropolitan Fire Department was destroyed in the first hour.

And still the bombers came.  George Seaton, flying a Superfort called Snatch Blatch, wrote “I could read a newspaper from the fires of Tokyo when we were still twenty minutes away.”  Jim Cornwell, who had flown over Hamburg in 1943 during an operation RAF Bomber Command called Gomorrah, recalled, “it looked like the roof of hell opened up, and Tokyo fell in.”

On the ground it seemed like the end of the world.  Fire destroyed neighborhoods in minutes, consumed blocks in seconds, houses in an eyeblink.  This was one of the most densely populated areas in the world, the third largest city on earth, and its residential heart was being consumed by fires that could not be stopped.  There were no firestorms like Hamburg; not enough concentrated heat.  Instead this was what firefighters called a sweep conflagration that grew and moved and fed on its own accord, fanned by southerly winds.  High above, as much as 20,000 feet above the maelstrom of fire, aircrews in the controller aircraft could smell burning pine…and hair, and flesh.

The last of the B-29s dropped its load sometime after 2:00 AM on 10 March, leaving a little over fifteen square miles of Tokyo burning or burned out, the flames having stopped only two miles from the Imperial Palace.  At least 80,000 were dead; possibly as many as 150,000–no one knows to this day for certain.  Downtown Tokyo was a charnel house; power and water systems destroyed; transportation networks completely knocked out.  Tokyo had become an abattoir of frightened refugees scrabbling amid the rubble and ashes to find enough food and water to survive.  By May, two more fire raids would only add another six square miles to the devastation.

With his new strategy Lemay laid waste to every Japanese industrial city that wasn’t on a special list from Washington: one that had on it Kure, Hiroshima and Nagasaki.  When he drove through Tokyo after the surrender, he saw thousands of tool posts standing stark amid the blowing ashes.  Japan may have already lost the war by March 1945, but at that time they didn’t know it.  After the fire raids, and Lemay ran out of targets to burn, the Showa emperor Hirohito certainly did.  After the Imperial War Council meeting of 10 August, he withdrew his support from the war.  He, like Tokyo, was done.

Manila: Stalingrad of the Pacific War

There is a great deal of danger in comparing anything to Stalingrad, or in saying that “X is/was the Stalingrad of Y,” if for no other reason than because Stalingrad was unique in the annals of warfare in sheer scale of misery and desolation, and its place in the strategy of the Russo-German War.  But in the perspective of the Pacific War, it is perhaps instructive to view the month-long city-fight for control of one of the jewels of the Pacific Rim as an example of the extreme depths of desperation the forces of Japan had sunk, and how the Americans had been compelled to fight the last of the samurai in a month-long slog of slaughter and destruction, not unlike the Germans and Russians in their death struggle on the Volga.

If the strategic situations were entirely different, the tactical ones were at least similar. From almost any perspective and by any measure, Japan had already lost the war in 1945; the Germans, in contrast, could conceivably have fought the western allies to a standstill in 1942 and turned their full attentions to the Soviets.  Thus, Manila meant nearly nothing because Japan couldn’t support any force there long-term, while Stalingrad had value as a foothold on the Volga and the hinge for the German armies in the Caucasus.  But short-term, if the Japanese could bloody the American juggernaut enough they just might make peace.  Or, at least, the samurai leadership told themselves that, and had been since Tarawa and the Gilbert Islands.

When the US 1st Cavalry and the 11th Airborne Divisions approached Manila in February 1945, the 16,000 Japanese defenders under Rear Admiral Iwabuchi Sanji had already written themselves off:

We are very glad and grateful for the opportunity of being able to serve our country in this epic battle. Now, with what strength remains, we will daringly engage the enemy. Banzai to the Emperor! We are determined to fight to the last man.

The Soviets were exhorted (if rhetorically) to fight to win.  Since a new Soviet soldier’s life expectancy at Stalingrad was about a day (and officers about three), this was pretty pointless.

The urban fighting in Manila was new to the Pacific War; not so much to the Russians and Germans.  The casualty rate was high, the noise and dust appalling and omnipresent in both cases.  But the defenders at Stalingrad, Vasili Chuikov’s little 62nd Army, would get relieved by the Soviet counterattack; there would be no rescue for the Japanese force.  When on 3 March 1945 the city had been declared secured the Japanese had died to the last man and boy, taking along with them about 100,000 Filipino civilians and nearly every structure in the city.  The Americans suffered some thousand dead and another five thousand wounded.

It is said that Soviet combat methods made casualties, not veterans, and the same can be said for the Japanese.  The island campaigns of the Pacific were fought in conditions unlike any before, where strategic retreat was possible only months before contact, but impossible because of the policies in Tokyo.  At the rate of destruction seen in Manila, by the time the war ended Japanese would indeed have been a language spoken only by the dead.

The February 26th Incident: A Window on the Samurai Soul

It is sometimes puzzling to the casual observer how very caustic the attitudes of the samurai leadership of Japan were before 1945.  Most non-Japanese would meet the February 26th incident with either blank stares or some attempts at putting the event on some bridge in China or a railway in Manchuria.  Though these events are distantly related, they are not, ultimately, what happened on 26 February 1936.
It was on that day that a faction of the Japanese Army attempted to eliminate their rivals in the military and the government.  The faction, called the Kodo-ha or “Righteous Army” (sometimes, Kokutai Genri-ha, or “national principle”), was composed primarily of company grade and junior field grade officers who were convinced that the country had strayed from the traditions of the Meiji Restoration of 1876, and that the Emperor should return to direct rule, instead of governing through a constitution or a parliament.  This would restore national prosperity, return Japan to its rightful and natural place in the scheme of the world, and enable Japan to purge itself of all evil western influences.
It was easy for the rest of the Army to oppose this movement, partly on the basis that many of the “western influences” that enabled Japan to even get a seat at the table of negotiations with the United States and Great Britain were not on the list of “evil” that the faction decried.  Like many radical movements, parts of it simply don’t make any sense.  But others, like ensuring the Emperor’s peace of mind, carried the seeds of samurai arrogance that wished to spread beyond the bounds of the Home Islands.
The attempted coup failed after some four days of tension and violence, but not before the murder of two former prime ministers, Takahashi Korekiyo and Saitō Makoto, and a number of others.  The secret trials took eighteen months.  Nineteen of the conspirators were executed.  But rather than have any thought of a Showa Restoration be extinguished, it became what could be called today a meme, if a false one.  The Army would use the idea that everything they would do right up to 1945 was in the name of, and for the well being of, the Emperor.  Unfortunately, Hirohito was more than willing to go along with whatever they wanted, aware that there was not a lot he could do to stop it.  If provoked, the samurai leadership would either assassinate or imprison him, name his young son emperor and place some general in place as regent (as had happened to his father, the Taisho).  It would be 1945, under the direct threat of invasion of the home islands, before Hirohito would cast caution aside and stop the militarists by withdrawing his support for their actions.
What Were They Thinking: A Fresh Look at Japan At War, 1941-45 examines the consequences of an isolated society dominated by a subgroup that saw themselves as “moderates” if they only wanted to exterminate one neighbor, as opposed to the “extremists” who wanted to dominate a third of the world.  Available in hardbound, paperback or PDF.

Iwo Jima: Strategic Convenience and Shape of Things To Come

The 19 February 1945 American invasion of Iwo Jima in the Bonin islands  was one of those peculiar events that means different things to different people.  The Bonin archipelago (also called the Ogasawara islands) is a volcanic desert: Iwo Jima, the largest of the islands, had no natural water sources and no place that could be used as a harbor.  The only reason anyone ever went there before the 1940s was because it was empty.  An American whaling outpost was established there in the 1830s after Spain and Britain had laid claim to it over the centuries, and Japan was the last to claim ownership in 1862.  No permanent residents were ever “permanent,” but transient fisher folk.

By early 1945, it was clear that the Americans were headed for the home islands of Japan.  Japan had fortified the place and built air fields, they realized that they could not hold the Bonins.  The Japanese 31st Army,  therefore, would be sacrificed in place.  The scanty air units were withdrawn in the face of fifty-odd American aircraft carriers.

At the time, the reasoning given for the invasion was to provide a fighter escort base for the B-29s attacking Japan out of the Marianas islands, and as an emergency landing field for crippled bombers.  About halfway between Japan and Saipan, the northernmost of the Marianas, this claim passes basic geographic muster,  But since the place was useless as a base for either the Army ground forces or the Navy, did the Air Force really need a base with no natural water?

Even the “fighter escorts for the bombers” claim was dubious.  Army fighters had the range to reach some of the big Honshu Island of Japan from the Bonins, but lacked the navigational equipment necessary for long flights over water.  Further, the Air Forces were changing tactics since their European-style high level daylight bombing wasn’t working in the Pacific.

After some 25,000 casualties (nearly 7,000 dead) in the six weeks fighting for Iwo Jima (Chichi Jima, a smaller rock with fewer flat spaces, its own water and a small harbor to the north, fell almost bloodlessly in less than a week) it raises a question: how many Marine lives does it take to save Army Air Force lives?  Of the 2,600 bombers that landed there, less than half “needed” the emergency fields, according to one estimate.  In this view, then, some 13,000 Army air crewman were saved.  The Japanese lost over 18,000 over the sulfurous wastelands.  “Worth the cost” has a whole new meaning with such numbers.   Furthermore, there is a school of thought that suggests that the three Marine divisions used in the Bonins were used up to be kept away from Douglas MacArthur in the Philippines, or his plan for Formosa.  Idle, those 50,000 men and supporting fleets were a tempting tool.  Deployed, they were beyond MacArthur’s reach.

Ultimately, however, like Peleliu, the Japanese needed the Bonins more than the Americans did, and that was the point. The Americans were taking strategic targets from the Japanese because they could, and each one hurt.  But too, like Okinawa would in a few months, it demonstrated to the Marines what the Army had found out on Saipan: the Japanese would fight to the death; military, civilian, man, woman, child–it mattered not.  What Were They Thinking: A Fresh Look at Japan At War, 1941-45 is a study of the Japanese mindset, available at fine bookstores everywhere.
