When Starfleet gave a warning surrounding Federation vessels disappearing in the Laurentian System the Starbase was put onto alert -- and when it was discovered that starbases from the Republic and Empire had been destroyed, it became evident that 777 may be the next target. Orders were given to evacuate all civilians and non-essential personnel to the USS Eventide in what would be its first deployment. The ship's progress was swiftly halted by warbirds blocking the way and the station found itself with its power disabled somehow, leaving them defenceless to a mercenary raid.
When the mercenaries fought their way to Starbase Operations it was revealed that they were here in order to obtain equipment, supplies, weaponry, and servants. 777's officers successfully managed to ward away a fair number of the mercenaries but it was then found why they had began to retreat: the station had been rigged to explode. It was with the expert work of Engineering and Operations officers that they managed to disable the explosive device and save the station from further harm.
Eventide - despite being under attack - managed to transmit a distress call to Starfleet who reported that their closest vessels were an entire day away. Eventide managed to hold off continued attacks and hold out until the arrival of a rescue fleet which successfully towed them back to Starbase 777. With the ship and starbase both heavily damaged masses of officers beamed aboard to help in the efforts to treat the wounded and repair the damage. With a reported 80% of its crew having perished in the siege, the attack here was noted as a true tragedy for Starfleet.
