Sixty-six years ago this week, US policymakers and President Truman made fateful decisions that meant the use of two atomic bombs against Japanese cities was almost inevitable—virtually unstoppable. Then film footage and other evidence of the true effects of the bomb were suppressed for decades. We’ve been living with the nuclear after-effects ever since, from Hiroshima to Fukushima.

Starting Monday, and related to publication of my new book and e-book Atomic Cover-up, on that film’s suppression, I began offering a daily record of what transpired leading up the bombing of Hiroshima and Nagasaki in 1945. (For more, including video, see my personal blog.)

On this day in 1945:

—Truman wrote letter to wife Bess from Potsdam on deals there (but does not mention A-bomb discussions with Soviets): “I like Stalin. He is straightforward, knows what he wants and will compromise when he can’t get it. His Foreign Minister isn’t so forthright.“ Truman casually informed Stalin about the atomic bomb but no one is quite certain that the latter understood.

—Japanese sub sinks the U.S.S. Indianapolis, killing over 800 American seamen. If it had happened three days earlier, the atomic bomb the ship was carrying to Tinian would have never made it.

—A Newsweek story observes: “As Allied air and sea attacks hammered the stricken homeland, Japan’s leaders assessed the war situation and found it bordering on the disastrous…. As usual, the nation’s propaganda media spewed out brave doube-talk of hope and defiance.” But it adds: “Behind the curtain, Japan had put forward at least one definite offer. Fearing the results of Russian participation in the war, Tokyo transmitted to Generaliissimo Stalin the broad terms on which it professed willingness to settle all scores.”

—Assembling of the first atomic bomb continued at Tinian. It would likely be ready on August 1 and the first use would be dictated by the weather.

—The second bomb—the plutonium device—was still back in the States. The target list, with Hiroshima as #1, remained in place, although it was being studied for the presence of POW camps holding Americans in the target sities.

—Secretary of War Stimson began work on the statement on the first use of the bomb that President Truman would record or release in a few days, assuming the bomb worked.

Greg Mitchell’s new book (also out as an e-book) is Atomic Cover-Up: Two US Soldiers, Hiroshima & Nagasaki, and The Greatest Movie Never Made. He also co-authored, with Robert Jay Lifton, Hiroshima in America.
