America, through a combination of luck, terrain and strategic ruthlessness had managed to survive.
On both coasts there were plains which, except for specific cities, had been ceded to the Posleen. But the north-south mountain ranges on both sides of the continent, along with the Mississippi, had permitted the country to reconsolidate and even locally counterattack.
In the West the vast bulk of the Rockies protected the interior, preventing a link-up between the Posleen trapped in the narrow strip of land between the mountains and the sea. That narrow strip of land, however, had once contained a sizable percentage of the population of the U.S. and the effect of the dislocation and civilian loss there was tremendous. In the end most of the residents of California, Washington and Oregon made it to safe havens in the Rockies. Most of them found themselves in the still-building underground cities, the "Sub-Urbs" recommended by the Galactics. There they sat, working in underground factories to produce the materials the war needed and sending forth their hale to defend the lines.
There were many untapped sources of materials in the Rockies and all of them were being exploited, but what was missing was food production. Prior to the first landing all holds had been released on agricultural production and the American agricultural juggernaut had responded magnificently. But most of the spare food had ended up being sent to the few fortified cities on the plains. They were scheduled to hold out for five years and food was their overriding concern. So there was, elsewhere, a severe shortage when the first massive landing occurred. Almost all the productive farmlands in the west, with the exception of the Klamath Basin, had been captured by the Posleen. So most of the food for the Western Sub-Urbs had to be provided over a long, thin link across the Northern Plains following I-94 and the Santa Fe Railroad. Sever that link and eighty-five million people would slowly starve to death.
In the east it was much the same. The Appalachian line stretched from New York to Georgia and linked up with the Te
The importance of the Appalachian defenses could not be overstated. With the loss of the coastal plains, and much of the Great Plains, the sole remaining large areas for food production were Central Canada, the Cumberland plateau and the Ohio Valley. And although the Canadian plains were high quality grain production areas, their total production per acre was low and they were effectively unable to produce a range of products. In addition, while there was increasing industry throughout British Columbia and Quebec, the logistical problems of a broad-based economy in nearly sub-Arctic conditions that had always plagued Canada continued even in the face of the Posleen threat. It was impossible to shoehorn the entire surviving population of the U.S. into Canada and if they did the survivors would be no better off than the Indians huddling in the Gujarrat and Himalayas.
Lose the Cumberland and Ohio and that would be for all practical purposes the end of active defense. There would be humans left on the continent, but like all the other major continents, they would be shattered survivors digging for scraps in the ruins.
Knowing that the lower Great Plains were indefensible the forces there, mostly armor and Galactic armored suits, had retreated, never engaging unless they could inflict terrific casualties. This retreat had ended near the Mi
All of these defenses were predicated on the Posleen's major weaknesses: inability to handle artillery and inability to cross significant barriers. The God Kings were able to engage aircraft and missiles with almost one hundred percent certainty but still were unable to stop indirect, free-flight artillery. So as long as they were in artillery range of humans they were vulnerable. And because of their odd mental dichotomy, it was virtually impossible for them to overrun modern defensive structures. Posleen attacks that carried the first layer of a prepared defense normally involved casualty rates of one hundred Posleen for every human killed; even with their overwhelming numbers they simply could not take more than the front rank of a prepared defense. And virtually all the defenses along the Rockies and Appalachians were layered with large units up and multiple supporting units. So the Posleen came on and they died in such vast numbers that it was impossible to count. And they lost. Every time.
Now, in most areas humans crouched behind their redoubtable defenses while the Posleen created a civilization just out of artillery range. And in between was a weed-choked and ghost-haunted no-man's-land of shattered towns and ruined cities.
And it was this wilderness through which the LRRPs patrolled.
"Let's head out," Mosovich said quietly, slipping his binoculars into their case. The binos were old technology, not even light gathering, but in conditions like this they worked well enough. And he liked to have a completely nonelectronic backup; batteries, even GalTech batteries, ran out. "I suspect those guys were headed south towards our target."
"What, exactly, are we supposed to do against a globe, Jake?" Mueller asked. But, nonetheless, he headed down the slope to the south.
The week before one of the gigantic "battleglobes" of the Posleen invader had been detected in a landing pattern. The vessel had landed with more control than normal for the Posleen. Usually the landings were more or less at random but this globe landed in one of the few areas in the Eastern U.S. that was not covered by heavy fire; the Planetary Defense Center that would have interfered with the landing had been destroyed before completion.
The globes were made up of thousands of smaller vessels from multiple worlds. They formed at predetermined deep-space rendezvous then proceeded to the target planet. When they reached the outer strands of the atmosphere the globes broke up and the subvessels, Lampreys and Command Dodecahedrons, would fan out in a giant circle around the landing target.
It was one of these that had landed somewhere around the already conquered Clarkesville, Georgia. And it was the LRRP's job to find it and find out where the forces from it were going.
So far it looked like they were gathering forces, not leaving. Which was, to say the least, unusual.
"First we find it," said Mosovich. "Then we figure out what to do."
Finding it would be difficult. There were parties of Posleen moving everywhere throughout the rugged countryside. Since the centauroid Posleen found mountains difficult, that meant they were confined to the roads. That meant in turn that the LRRP team had to be careful to avoid roads. The best way to do that would have been to "ridge run"—follow ridges from hilltop to hilltop. However, the general trend of the ridges in the North Georgia hills was from east to west, rather than north to south. Thus the team had to first climb up one ridge, averaging from two to six hundred feet, then down the other side. In the valley they would carefully cross the inevitable stream and road, then ascend the next ridge.
