There is a general
consensus that the closing days of World War II went something like this: On August 6, the United States dropped the
first atomic bomb on Hiroshima. Three
days later, on August 9, a second atomic bomb was dropped on Nagasaki. After a couple of days of communications,
Japan agreed to surrender terms on August 14, and the actual surrender document
was signed on September 2, 1945, ending the war.
That chronology is
correct, but it leaves out a significant number of important events that
affected the surrender. Both the Soviet
Union and Mongolia declared war on Japan following the attack on Nagasaki, the
Chinese Civil War resumed, Korea was invaded by Russia, the Allies had a resounding
victory over the Japanese forces in the Philippines, and the United States
dropped leaflets warning of future nuclear attacks on all the major Japanese
cities—all of these events happened in the week following the bombing of
Hiroshima.
One event that is
missing from this list, which is rarely mentioned in history books (or in war
documentaries, or in Hollywood movies), is the last bombing mission of the war,
when over 1,000 American planes attacked cities across
Japan. The event is rarely mentioned for
two reasons: First, the bombing raid is
relatively unimportant compared with the enormous consequences of the end of
the war or the first use of nuclear weapons.
Second, many accounts of the last days of the war focus on the morality
of using those nuclear weapons. (An
argument that I have no interest in reviving in a blog post of only 1,241
words.)
By November of
1944, the United States was able to begin devastating strategic bombing raids
on Imperial Japan. The production of
thousands of long-range B-29 bombers (each capable of dropping up to ten tons
of explosives), coupled with suitable runways built on the recaptured Marianas
Island, meant that twice the monthly tonnage of bombs that had been dropped on
Germany could now be dropped on Japan.
In addition, the
bombing raids on Japan were more destructive because the United States had made
improvements in the incendiary explosives that proved to be particularly
effective on the type of construction used in Japanese cities. The use of incendiary bombs on Tokyo in the
spring of 1945 were so effective that the city was ruled out as a possible
target for nuclear weapons—in part because the city had suffered so much
devastation that it was feared that Japanese officials would not be able to
appreciate the destructiveness of the atomic bomb.
Nicknamed
“firebombing”, incendiary raids on Japanese industry were far more effective
than using conventional explosives owing to the Japanese custom of putting
factories in densely populated areas of cities.
Realizing the effectiveness of this new tactic, American napalm
production increased by 700% in 1944. In
the test of the new tactics, American bombers destroyed a square mile of the
industrial area of Tokyo.

glance, this looks like Hiroshima or Nagasaki after the nuclear attack, this is
Shizuoka after it was firebombed in June, 1944.
A string of
islands in the Marianas had been turned into bomber bases, each capable of
launching 80 to 120 large bombers. From
the Marianas, the bombers flew 1,500 miles to Japan—the equivalent of taking
off in Canada to bomb Mexico. Along the
way, as the bombers passed Iwo Jima, they were joined by fighter plane escorts
of P-51 Mustangs outfitted with belly tanks to extend their range. After dropping the bombs on their targets,
the planes reversed course, landing back in the Marianas more than fifteen
hours after they had taken off. These
were the longest bombing missions ever undertaken.
Most people are
still surprised to learn that the single most deadly aerial bombing mission
during World War II did not use nuclear weapons. On March 9, 1945, 334 B-29 bombers based in
the Marianas dropped 1,667 tons of napalm and petroleum jelly cluster bombs on
Tokyo. More than 100,000 people died,
injuring several times that number and destroying 267,000 buildings. This remains the highest death toll on any
air raid in history, including Hiroshima and Nagasaki. The raid was roughly four times as
destructive as the firebombing of Dresden, which had occurred a month earlier.
On August 10, the
day after the atomic bomb had been dropped on Nagasaki, the Japanese began
preliminary surrender talks with the United States, generally agreeing to the
terms previously laid out in the Potsdam Conference, but insisting on allowing
Hirohito to keep his historical titles and powers—a rather large exception to
the unconditional surrender demanded by the Allies.
During this time,
two smaller bombing raids were conducted by the Army Air Corps. A night time raid was conducted against an
oil target, and a precision daytime raid, on a factory in Tokyo. The next day, all strategic bombing was
canceled by President Truman, to encourage the Japanese to continue
negotiations for surrender. Truman also
knew that if bombing continued, it might appear that the talks had stalled,
resulting in a loss of morale in Americans who were already jubilant at the
prospect of an end to the war.
On August 13,
American bombers once more took to the air, but the payloads were leaflets that
outlined the Japanese government’s conditional offer to surrender. All major Japanese cities were targeted to
receive the propaganda. This was
actually the third time in less than thirty days that leaflets had been
dropped. The first, on August 3, had
been dropped by the millions on 33 cities (including Hiroshima and Nagasaki)
warning that America had the military power to utterly destroy Japanese
cities. Nicknamed the “Lemay Leaflets”,
it pictured five B-29 bombers firebombing Yokohama. On their second mission, following the
bombing of Hiroshima, warning leaflets that included a photo of the mushroom
cloud over that city were dropped, warning citizens of specific cities that
they should evacuate these targets immediately.
When the surrender
negotiations had made no progress, the President allowed bombing to resume on
August 14. General Hap Arnold planned
for the largest bombing mission in history—over a thousand planes to attack
multiple Japanese cities at the same time.
There were 828 B-29’s escorted by 186 P-51 fighter planes, for a total
of 1,014 aircraft, that attacked targets at Iwakuni, Osaka, Tokoyama, Kumagaya,
and Isesaki (the last two targets were firebombed). The farthest target, the Nippon Oil Refinery
at Tsuchizakiminato, was destroyed.
That last target
is all but unpronounceable for Americans, so it is usually listed in history
books as Tsuchizaki—or even more likely, Akita after a town five miles from the
refinery. Today, a memorial to the more
than 250 civilians killed in the raid stands at Akita.
During the return
flight of their fifteen-hour mission, the planes received a radio message
informing them that after their successful attack, Japan had radioed an
acceptance of Allied surrender terms. At
noon, the next day, August 15, Emperor Hirohito made a radio broadcast
announcing his country’s intention to surrender.
The longest air
raid (and the largest air raid of the war) is all but forgotten today, rarely
mentioned in history books or listed in timelines of the war. When the planes took off, the world was at
war and by the time they all landed (and all returned safely), the world was—at
least temporarily—at peace.
