"The crew had apparently been prepared for their visit. They planted a strange device atop a flimsy tower in a field, and embarked instantly. Within a matter of three minutes, as well as we have been able to determine, the device detonated with unbelievable force. Over a square mile was absolutely desolated; casualties ran into the thousands. And the entire area still remains poisoned with some form of radiation-producing debris which renders the region uninhabitable." I nodded. "I think I understand," I said. "Yes," the general said, "you have something of this sort in your B-I Three world also, do you not?" I assumed the question was rhetorical and said nothing. Bernadotte continued. "Crude though their methods are, they have succeeded already in flaunting the Imperium. It is only a matter of time, we feel, before they develop adequate controls and detection devices. We will then be faced with the prospect of hordes of ragged but efficient soldiers, armed with the frightful radium bombs with which they destroyed their own culture, descending on the mother world of the Imperium. "This eventuality is one for which it has been necessary to make preparation. There seemed to be two possibilities, both equally undesirable. We could await further attack, meanwhile readying our defenses, of doubtful value against the fantastic explosives of the enemy; or we could ourselves mount an offensive, launching a massive invasion force against B-I Two. The logistics problems involved in either plan would be unbelievably complex." I was learning a few things about the Imperium. In the first place, they did not have the atomic bomb, and had no conception of its power. Their consideration of war against an organized military force armed with atomics was proof of that. Also, not having had the harsh lessons of two major wars to assist them, they were naive, almost backward, in some ways. They thought more like Europeans of the nineteenth century than modern westerners. "About one month ago, Mr. Bayard," Bale took over, "a new factor was introduced, giving us a third possibility. In the heart of the Blight, at only a very little distance from B-I Two, and even closer to us than it, we found a second surviving line. That line was of course your home world, designated Blight-Insular Three. "Within seventy-two hours one hundred and fifty special agents had been placed at carefully scouted positions in B-I Three. We were determined to make no blunders; too much was at stake. As the information flowed in from our men, all of whom, being top agents, had succeeded in establishing their cover identities without difficulty, it was immediately passed to the General Staff and to the Imperial Emergency Cabinet for study. The two bodies remained in constant session for over a week without developing any adequate scheme for handling the new factor.
