of microfilm. The white-faced communications sergeant stood just inside the door, and this time he failed to be impressed with the unusual smartness of the Colonel's acknowledging salute. The thick sheaf of yellow papers he held in his left hand was trembling visibly, noisily, and he couldn't make it stop. "Well, Grady, what is it? You look as though you'd picked up a telepath message from one of our Callistan cap-crawlers, or something--" He reached out for the quaking message the sergeant held, and the communications man smiled nervously and held it out to him. "Sorry, sir. I--I guess I just--" "No trouble, boy?" The stocky black-and-silver uniformed figure paused in its movement, the thick pile of yellow papers momentarily forgotten. All of Steele's personnel seemed like sons to him. Even the raw recruits who had previously never been further out than Earth's own Moon. Sometimes, during the lonely hours there had been in the fastnesses of Space, he had surmised it was because there had never been a real son of his own with whom to share the adventures of his calling.

Steele ran a freckled, stub-fingered hand slowly and deliberately along the close-cropped iron-gray side of his squarish skull. _Attention all stations, the message read. URGENT IMPERATIVE. Earth has been successfully invaded. The rapidity, timing, and infallibility of the attack has made the necessity of immediate capitulation unquestionable. The following-listed units are therefore commanded, for the good of the planet, to return to home Earth bases at once, with all armament either completely dismantled or destroyed. The conquerors have warned that failure to comply with this command will result in wholesale liquidation of Earth's populace._ The long list of outposts followed for fifteen closely-spaced pages. The message was signed _Taylor, General, New United Nations World Space Force, Commanding_. Steele suddenly felt himself struggling to keep order for full-scale attack bottled in his throat. Then he fought to keep from simply cursing. He fought to keep the hot, quick panic
