They came aboard a fleet of fifty ships that hovered over Earth's greatest cities from Los Angeles to Paris to Moscow. The Visitors offered technology and knowledge in exchange for resources Earth had in abundance. They came in peace they said.
They lied.
And were it not for Teal'c, Earth would have believed them. Some would have been skeptical at first, but they would have been lulled into believing by the friendly Visitors. It was, Teal'c explained, their modus operandi. On the many worlds where humans and jaffa slaved for the goa'uld, whispers of the Visitors kept the slaves from rebelling against their goa'uld masters. Teal'c detailed what he remembered from the reports of the few survivors from worlds the Visitors had invaded. It would begin he said with people disappearing. On some worlds, it was the scientists that disappeared first while on others it would be the warriors or the clergy or those who were different in some way. The Visitors always chose one group to set the general population against. These fears would be fed by those the Visitors would brainwash to turn against their own. As the fears of the native population grew, the Visitors would begin to secretly loot the resources they needed. It was better to be a slave than cattle, Teal'c told those assembled in the White House Situation Room to hear his briefing, as he explained the eating habits of the Visitors. More than a few of the assembled faces went from the pale of shock to sickly green.
"So what do we do?" President Hayes asked when Teal'c had finished.
Teal'c immediately spoke surprising O'Neill and Hammond with his vehemence. "They must not be allowed to learn of the Stargate," he said.
"Teal'c is right," General Hammond agreed. "The SGC's going to be our best shot at getting more intelligence on these Visitors, more weapons to fight them. In the worst case scenario, Mr. President, the Stargate will be our best chance of getting as many of our people away from them as possible."
"The SGC needs to fall off the map," Colonel Jack O'Neill declared from his seat beside Hammond having spent the entire briefing mulling over possibilities in his head. "You heard what Teal'c said about their brainwashing techniques. We need to move now before they infiltrate us."
The arguments went back and forth for hours, but in the end Hayes agreed. In the following days, all trace of the SGC in government records and computers was destroyed. At the same time a steady stream of supplies were carried through the Stargate to the Alpha and Beta sites as the SGC was quickly and efficiently dismantled from within. Five days after the Visitors arrived, two trucks left the Cheyenne Mountain complex headed for Wright Patterson Air Force Base. They never arrived. Instead the two trucks found their way into the depths of a pit mine somewhere in the Midwest. The Stargate was quickly reassembled and put back into operation as personnel and supplies began streaming back to Earth from the Alpha and Beta sites. The miles of tunnels that spread like a spiders web under the town made the mine an ideal base, and the constant coming and going of trucks would help hide their movements. The resistance had begun.
