I got the idea for this fic from Star Trek: Armada, it is about Captain Thaddeus Debbing and ship and crew of the U.S.S. Premonition. The story takes place in the timeline the Premonition is from. But this is what happens to the Premonition before Armada.
Premonitions


Prologue


"Picard, lower your shields. The rest of the fleet will be assimilated, however you and the Enterprise are too great a threat to the collective, you will be destroyed," said the assimilated clone.

"Locutus, if you are truly who you appear to be then you must know I will not comply," responded Picard.

"You will comply, your defensive capabilities are no match for us," said Locutus. Locutus's image went off the viewscreen to show the cube the drone was commanding. The cube's tractor beam's green light then obscured the image with a flash.

Picard felt the Enterprise lurch forward. "Target these coordinates and fire," he commanded the fleet. But it was too late, before the tactical officer could push the button the Enterprise and her crew was gone.

Three days later...

Locutus's cube and escorts orbited Earth with its gray waters, transportation tubes and gleaming cities off Borg.


Chapter One


Eleven years later...

"Target that sphere," said Thaddeus Debbing. As he thrust his finger forward he said, "Fire!" Debbing watched the viewscreen as the Premonition's photophasic torpedoes destroyed a Borg sphere firing on a Klingon Negh'Var-class warship. He watched as the sphere exploded over the atmosphere of Qo'noS. Had the Borg not assimilated Earth eleven years before there would have been no Battle of Bajor, Battle of Vulcan, Battle of Romulus, or Battle of Qo'noS.

He kept his eyes on the viewscreen, "Captain," said Lieutenant Tram, the ship's tactical officer, "Three Borg cubes are coming out of transwarp!"

"Contact the fleet," Debbing told Commander Watkins, who was manning the communications station but was really second-in-command, "And tell them to fall back".

"Sir?" asked Watkins.

Debbing gritted his teeth and said, "Tell them to fall back. We'll all rendezvous back at Starbase 112.

Watkins nodded, he tapped the hail button and said, "This is the Premonition, fall back. I repeat, fall back". Watkins pressed a button that was flashing red and pressed it. A picture of the Klingon's fleet commander appeared.

"Why are you retreating you Pat'akh?" said the Klingon.

"Because we cannot win this fight," said Debbing.

The Klingon gritted his teeth, "Very well. You cowards may retreat, but I wish to go on to Stovokor!"

The image of the Klingon went off the screen to show the Negh'Var class ship the fleet commander was on be destroyed by two Borg cubes.

As the Premonition and the other ships in the fleet retreated Debbing thought about all the years he and the other people of the Federation had lived in fear. After the Borg cloned captain Jean-Luc Picard and assimilated the clone, they began an invasion of the Alpha Quadrant. First they captured the Omega Particle from the Romulans, which only increased their power. Then they began an invasion of Federation space in which they assimilated Earth. After the assimilation of Earth the Borg went after Vulcan, Bajor, Romulus and Remus. And after Eleven years the only planet left that even had relation to the Federation was Qo'noS, but know it had fallen to the Borg. The only thing that barely gave them a fighting chance was the Borg fighting technology that Captain Janeway brought back from seven years in the Delta Quadrant. Luckily she got back just before the invasion. But now the Borg had found ways to protect themselves from everything Janeway brought back. Life in the Alpha Quadrant, the Beta Quadrant, and the Gamma Quadrant had become a living hell.

"Sir the Borg are following," said Tram.

"Well, then let's see if this temporal stasis field really works," said Debbing. "Lieutenant Tram, activate the Temporal Stasis Field." He watched the ensign press a few buttons. Then he heard the beep of the sensors.

"Captain," said Tram, "I'm detecting a temporal distortion around the Borg ships".

"Put me through to the fleet," said Debbing.

"You're on, sir," said Tram.

"This is Captain Debbing, all ships target those cubes," said Debbing. He watched as a casqued of phasers and torpedoes destroyed the two cubes. "Alright, everyone let's get back to the Baku system." He looked at Commander Watkins. "Jack you have the bridge. I'll be in my ready room". Debbing walked into his ready room and over to his desk. He sat down in his chair and tapped the voice command button on his computer. "Computer, play the message containing blueprints on the Temporal Stasis Field".

A picture of an awfully frightened and beat-up looking man appeared on the computer's screen. "Captain Debbing, this is the Temporal Research Facility called the Goddard Station. By the time you receive this message this station will have been assimilated or destroyed. This message contains the blueprints on the Temporal Stasis Field or the TSF. We have spent the last year here researching a method of freezing enemy ships and stations in time without affecting our own ships. These blueprints also show how to adapt the TSF for use on your own ship."

A voice in the back round suddenly yelled out, "Sir, I'm detecting transwarp signatures!" Then an alarm started going off.

"Good," said the man on the screen said, "I just completed transmitting the blueprints. Goodbye captain". Then static over ran the screen.
