The Enterprise-F fleet (the component ships) headed towards the rendezvous to destroy the S-Cube. They saw the Cube go by and then Worf activated his cloaking device and they combined. They approached the Borg cube still cloaked and prepared to strike. They powered up their weapons, de-cloaked, and vaporized the cube in a single shot.

"Now where was the challenge in that?" asked Wesley Crusher from the helm.

"It wasn't supposed to be hard," said Worf "these ships were designed specifically be able to crush the Borg."

"I'd say they accomplished that nicely, wouldn't you captain?" asked Will Riker.

"Oh shit!" exclaimed Wesley "we screwed up, the H-Mine sphere is activating their time travel thingy!!!!!!"

"Fire Mr. Worf!" ordered Captain Picard. Worf fired, but the sphere entered the thingy just in time.

"All ships, follow that sphere!!!!!" ordered Picard the Enterprise-F made it through, but when the Enterprise-E was halfway through it, it dissolved!

Yes I know Thingy isn't the right name, but I'm supposed to be doing homework and didn't feel like re-reading Star Trek: First Contact
