Since 1910, Newgate, New York had been a full supporter of the work the Alien Cooperation Enterprise was doing.  People were shifted to the dimensions where it operated and many research projects were done at the University of Newgate. 

Evil alien races looked at earth as a place where raw materials were abundant and the primitive people would pose no problem with an invasion.  What the people weren’t counting on was the resistance the other dimensions would put up to protect this planet.  The people in Newgate were some of the first in this dimension that contributed in the defense of the earth. 

There was one earlier war that took place at the time of the American Civil War.  But it was minor and was quickly resolved.  But the all-out war that nearly allowed a combined federation of planets and empires to invade earth happened between June 8, 1938 and August 4, 1949. 

The Kuyper Belt War, or KBW 2, began when a small fleet of starships that were a part of ACE came in contact with the Dorellian Fleet in the Kuyper Belt on June 8, 1938.  It was on its way to invade the earth and take advantage of the turmoil the Japanese caused by invading China and the Germans and Soviets being involved in the Spanish Civil War.  With the world about to enter a world conflict, the Dorellians headed toward this planet to conquer it. 

What they didn’t count on was a fierce defense by ACE.  There were a dozen starships of various sizes that were navigating the Kuyper Belt when the Dorellian Fleet made up of a dozen heavy cruisers and twenty shock destroyers met them.  Since the ACE commanders were very familiar with the belt, they broke off into small three-ship attack formations that combined force fields to make three ships fight as one more powerful ship.  

The heavy cruisers were lumbering beasts that couldn’t maneuver all that well amidst the rocks and planetoids of the region.  They were easy targets and were taken out early.  But the shock destroyers that were smaller and more agile gave the starships quite a fight.  They hadn’t mastered the technique of field combining to make the ships more potent, so they had a tough time with the ACE starships. 

After losing 15 destroyers, the Dorellians retreated and headed back toward their home worlds with the ACE fleet in hot pursuit.   The alien crews knew about the Dorellian technique of drawing enemies out beyond their normal service radius and before they could call for reinforcements would be attacked and usually destroyed by overwhelming force.  But if the ships could be destroyed before they returned to the Dorellian System, there could be no counterattack waged against the pursuers.
