Great history lesson.
On June 12, 1944, every camera in the world was pointed at Normandy.
Which is exactly why almost nobody noticed the United States launching the operation that actually doomed Japan, on the other side of the planet, that same week.
Here is what the headlines missed.
While 9 divisions fought in the hedgerows of France, Task Force 58 was steaming toward the Mariana Islands: 15 aircraft carriers, over 900 aircraft, escorted by new fast battleships. It was the most powerful naval force ever assembled to that point, and the US had built it in under three years while also supplying the war in Europe.
On June 11 and 12, its planes hammered Saipan, Tinian, and Guam, destroying Japanese aircraft on the ground and in the air, and cutting the islands off from rescue.
Why these specific islands? One number explains everything: 1,500 miles.
That was the combat radius of the new B-29 Superfortress. From the Marianas, B-29s could reach Tokyo. Japan knew it. Their commanders called the islands the absolute national defense line, the wall that could not be allowed to fall.
So when US Marines hit the beaches of Saipan on June 15, just 9 days after D-Day, Japan did what the US Navy had been hoping for since Pearl Harbor. It sent its entire carrier fleet to fight.
The result, on June 19 and 20, was the Battle of the Philippine Sea, the largest carrier battle in human history. 24 carriers in one fight. It was so one-sided that American pilots named it the Great Marianas Turkey Shoot. Japan lost roughly 600 aircraft and 3 carriers in two days. American losses were a tiny fraction of that. Japanese naval aviation never recovered. It effectively died in those 48 hours.
The dominoes from this one week:
Saipan fell in July. The shock was so severe in Tokyo that Prime Minister Tojo's entire government resigned.
By November, B-29s from the Marianas were bombing Japan itself.
And in August 1945, a B-29 named Enola Gay took off from Tinian, one of the islands first hit in these June raids.
Think about that week in June 1944 again. The United States conducted history's largest amphibious invasion in France and simultaneously launched a second massive invasion 7,000 miles away in the Pacific, each one larger than anything any other nation could attempt alone.
D-Day gets the anniversaries. The Marianas got the verdict.
The war was decided in both oceans in the same seven days, and only one of them made the front page.
