Tibbets had a daunting task. He had to devise from scratch the means to deploy the new weapon, assemble and train the units to do it, all under an airtight shroud of security with little or no guidance from command, since command knew less than he did about the requirements.

He ranks as one of the giants of World War II leadership but was overshadowed by more celebrated military figures.
