I wasn't originally going to do this section, because the defenses of Bandon Station weren't really related to the Bastion's navy. But I did. So here it is.
Despite, or because of, the extreme secrecy around the Black Fleet demanded by Jonathan Cameron, Bandon Station did not receive a full SDS network. M-3s, M-5s, and the other elements that made up such networks were in high demand across the Hegemony, and diverting large numbers of materials and finished drones away from filling that demand towards a base that didn't officially exist would have raised too many questions.
What Bandon Station did have, especially after its updates, was a large number of automated repair bays, the protocols for installing SDS cores, and a vast amount of mothballed military hardware. These capabilities would be broken in on the mass conversion of over a hundred Baron class destroyers to M-4 Block III (designated in Bastion service as the M-4-3) drones for use in the Bastion and other top secret outposts. While the majority would be sent elsewhere, two modified variants (designated Block IIIA) would remain at Bandon Station as testbeds and guard vessels. Following the Amaris Coup, this defense force was expanded with the conversion of fourteen more drones, two Essex I and twelve vigilant class, organized into two flotillas of one destroyer and six corvettes. Roughly two hundred F-39 Diamondback fighters would also be converted to unmanned drones, providing twelve squadrons worth of fighter cover for each of the new flotillas, with the remainder kept at the station itself. Gun and missile batteries spread across the planetoid containing Bandon Station completed the defenses. While the DMR and the station's own controlling intelligences deemed these defenses inadequate against a determined attacker, there was no way to obtain the Nirasaki computer cores that would be necessary to expand the defense forces further, and even converting the ships they had had required cannibalizing some of the Station's own automated systems, shutting down the autonomous function of entire sectors of the massive complex.
The DMR's fears about the Station's safety would be proven fully justified, but surprisingly this would not take place until after the Amaris Coup had ended, and even years after Kerensky himself had departed on his own Exodus. The identity of the attackers remains unknown to this day, but in 2790 a force of seven WarShips, composed of a Black Lion, a Luxor, a pair each of Sovetski Soyuz and Lola IIIs, and led by a McKenna class battleship, entered the system and began an approach to Bandon Station. Rather than make any attempt at communication, the fleet instead opened with several volleys of nuclear tipped missiles, while simultaneously a powerful NIKE Jammer activated aboard the presumed flagship. Unable to register, track, or directly engage the attackers, the station's drone fleet would be briefly immobilized by the AI equivalent of indecision, resulting in the loss of a corvette and an M-4 from the enemy's first missile salvo before they began scattering away from the station. This maneuver prevented additional casualties among the drone force and, either through the attacker's inexperience or a desire to simply clear the drones off board, the attackers were baited into pursuing.
Now having at least a small luxury of time, efforts aboard the station turned to evacuation and sending out warnings. The most recent refugee convoy was almost loaded, but there still remained many thousands of civilians aboard the station waiting to load, and however this battle turned out, it was now clear that Bandon Station was no longer safe for those who were still on their way. The command center would send off several HPG messages reporting the situation to the Morgan Commissions agents, while within the station, the last of the refugees were being rushed aboard their waiting transports.
Meanwhile, unable to actually detect or directly target anything within the bubble of the NIKE jammer, the drone fleet would instead lob dozens, then hundreds of capital missiles on bearing only launches aimed at the approximate center of the jamming. Unlike the enemy's own missile strikes, which were trying and failing to hit a violently maneuvering and dispersed set of targets, the drone fleet's missiles descended on a concentrated and orderly force, albeit one protected by a substantial number of point defense escorts. Though a fair number of missiles would miss and many others would be intercepted over the next few hours of sustained bombardment, quite a number of hits would be scored, leading to a Soyuz and a Lola being crippled and falling out of line. A pause would follow as the drones reloaded their missile magazines with whatever spares they had in storages and the attackers reoriented their formations to account for their own losses and better protect themselves from a follow up attack. Their maneuvers also shifted their expected path of travel back towards Bandon Station. Though overcoming their current velocity and actually moving in that direction would take several hours at least, it would still put the station itself in danger. So, as their opponents continued their own long deceleration burn, the drone fleet burned hard to assemble for a fast pass directly through the center of the jamming. This did not start well, with the remaining M-4 in the fleet suffering an abrupt engineering casualty which caused it to fall behind the rest of the pack and forced it to break off. The rest of the drones executed the maneuver with machine like precision, descending on the unknown enemy just as they had reached their lowest point of deceleration. The electronic noise of the NIKE jammer screaming in their machine brains, the drones focused as much of their fire as possible on its source, the McKenna class battleship at the center of the formation, though every other gun that could brought to bear on any target also spoke. Behind the capital drones came their fighters, on their own single minded screaming pass, inflicting still more damage. The enemy McKenna staggered out of formation, badly hurt and its jamming system now completely offline, but still operational. The second Soyuz class cruiser, running close escort to the McKenna, was left drifting out of control, having lost main power and rapidly venting atmosphere. The enemy's fighters were still buttoned up in their bays for extended transit, so there was no fighter cover and little in the way of other air defense to repel the swarms of fighter scale drones as they ran past with all guns blazing, inflicting damage throughout the enemy fleet.
The price, however, was heavy. The enemy had known the attack was coming, and they'd likewise opened up with every gun available as the drones shot through their formation. Poor fire discipline offered some grim assistance to the drones, multiple ships concentrated their fire on the two Essex class destroyers leading the charge, absolutely eviscerating them but sparing several of the following corvettes from any fire at all. Many of the drone fighters, though not meeting any active resistance, still fell prey to the massive layered electronic countermeasures surrounding the fleet, either going feral or simply shutting down. Only seven Vigilant drones and roughly two thirds of the fleet's fighters would emerge from the pass in fighting trim. Meeting up with the limping M-4, they would continue in the direction of the station, preparing for the next, and what would very likely be the last, engagement.
The enemy, however, seemed to be in shock, and bled off the rest of their velocity to conduct search and rescue operations before holding position for several more hours, either trying to patch some of the damage they had sustained or trying to decide just what to do now. If they had attempted to restore their NIKE jammer, those attempts had failed, as the fleet now advanced without its coverage, the battered McKenna at the rear of the formation while the remaining ships assembled in an arrowhead formation ahead of it.
The time the drones had won from the enemy had been well spent however. Even as the enemy fleet began moving again, the last of the refugees and non-essential personnel that had been on Bandon Station were now on dropships outbound to the jumpship fleet waiting nearby. The station's own complement of drone fighters would accompany these ships to provide escort against a surprise strike.
With the evacuation complete, the drone forces would withdraw back towards Bandon Station with the intention of bringing the final confrontation within the bubble of the station's own guns. Seemingly anticipating this strategy, the attackers responded with a barrage of nuclear tipped missiles. Though they had proven unable to hit the agile drone capital ships, they had no problem landing hits against the station itself. Fifty peacemaker class warheads were launched at the station, twenty of them making it through the station's own point defenses to strike the planetoid's surface, seemingly targeted to clear out or suppress gun and missile batteries to create an opening in the station's defenses. Though the warheads that struck home lacked accuracy, they made up for it in shear destructive power, silencing several weapons emplacements and largely crippling the station's ability to fight back. The enemy fighters would not be caught napping this time, and waves of fighter squadrons would next descend on the drone fleet, swarming the defenders' badly outnumbered aerospace forces as the two lines of capital ships met. The engagement was brutally one-sided, with two corvettes almost immediately broken in half by the withering fire from the Black Lion and the Luxor. The M-4, still struggling to maneuver, would combine its fire with another pair of Vigilants against the enemy Lola III, inflicting heavy damage and forcing it to break off, but this small victory would be rendered moot as the McKenna entered the fray, raining hellfire down on the Lola's tormenters. The M-4's propulsion system failed, leaving it drifting towards an inevitable collision with the station, while one of her accompanying Vigilants practically disintegrated under the combined fire of the McKenna and the Luxor. As the Black Lion obliterated another ship, The remaining drones, their artificial intelligences having assessed the situation as hopeless, now resorted to the only weapons remaining to them. The three corvettes charged the enemy at maximum thrust, each aiming to take one of their opponents with them. Two fell quickly to the guns of the Luxor and the Black Lion respectively, but the third, against all odds, managed to strike the McKenna amidships, just below its iconic shark fin radiator. The tiny corvette seemed to crumple against the massive battleship, even as the battleship's hull collapsed inward under the impact. The tangled wreckage of both ships, either dead or dying, would slowly spin out of control, drifting into the empty void. Though the actual veracity of this next part is considered suspect, ships of the evacuation fleet would later report detecting one final signal from the unmanned drone, a simple text phrase.
"Go tell Kerensky, traveler passing by, that here, according to our duty, we lie."
But even that last sacrifice would not change the outcome of the battle. The remaining enemies would begin pounding Bandon Station relentlessly, suppressing the last of the weapons batteries to open a hole for their landing parties. As these boots touched the soil of the planetoid, however, Bandon Station and the last of the human personnel aboard denied them their prize. Nuclear scuttling charges ripped through the facility, destroying everything from the stations facilities to its control computers to the hundreds of ships that still remained stored within. The lives and ships this unknown enemy had sacrificed in this attack would be for nothing.
The refugee fleet would jump out of system shortly after, roughly two hours ahead of the angry cruiser burning hard to stop them. As such, determining the actual casualties on either side is difficult. There were still believed to be thirty people aboard Bandon Station at the time of its destruction, and it has to be assumed that none of them would have survived. The station's unmanned forces likewise lost sixteen capital ships and nearly one hundred and fifty fighters, with the only surviving units making up the escort of the refugee convoy. And of course there was the loss of the station itself. Enemy casualties are harder to pin down. It is considered a certainty that the McKenna class ship would have been a total loss, while all but two of the remaining ships suffered sufficient damage to force them to retire from the field. It is difficult, and perhaps inappropriate, to attempt to label either side as a winner or loser. The defenders has pulled of an impressive defense given the disparity in firepower between the two sides, but they had failed to hold Bandon Station in the end. Likewise, the enemy held the field after the battle, but the losses they had suffered in terms of functionally irreplaceable ships had gained them nothing at all. Most important of all, a vital lifeline that had allowed tens of millions of innocent civilians a chance to escape the catastrophic devastation encompassing the Inner Sphere had been closed.
In subsequent years, expeditions to the system where the remains of Bandon Station lie have found nothing but a dead and abandoned husk. While it has been speculated that some portions of the vast facility might still remain undamaged beneath the rubble, actually excavating the ruins would be an undertaking out of the reach of what remains of the Morgan Commission in the Inner Sphere. Instead, the station has been left undisturbed, a memorial to that terrible day.
