" Some optimistically hoped the unprecedented bombing of the tiny island would make the conquest of Iwo Jima a two- to three-day job. But on the command ship USS Eldorado, Howlin' Mad shared none of this optimism. The general was studying reconnaissance photographs that showed every square inch of the island had been bombed. "The Seventh Air Force dropped 5,800 tons in 2,700 sorties. In one square mile of Iwo Jima, a photograph showed 5,000 bomb craters." Admiral Nimitz thought he was dropping bombs "sufficient to pulverize everything on the island." But incredibly, the enemy defenses were growing. There were 450 major defensive installations when the bombing began. Now there were over 750. Howlin' Mad observed: "We thought it would blast any island off the military map, level every defense, no matter how strong, and wipe out the garrison. But nothing of the kind happened. Like the worm, which becomes stronger the more you cut it up, Iwo Jima thrived on our bombardment. "
