{{Quote|With tensions rising on both sides, violence once again rocked the Outer Colonies. It was the Callisto Incident that tipped the scales.|[[Curator]]{{Ref/Reuse|mythos55}}}}

The '''''Callisto'' Incident''' was a violent encounter between forces of the [[Unified Earth Government]] and local [[terrorist]]s from [[Levosia]] in the [[26 Draconis system]], ultimately inflaming violence across the [[Outer Colonies]] and triggering the [[Insurrection]]. While patrolling the 26 Draconis system, the [[corvette]] {{UNSCShip|Callisto}} conducted an inspection aboard a merchant ship that turned tragically violent when shots were fired, resulting in thirty deaths.{{Ref/Reuse|he279}}

''Callisto'' would later be hijacked by terrorists, forcing the [[United Nations Space Command]] to respond by deploying a [[battle group]] of three [[destroyer]]s. The following engagement resulted in the destruction or crippling of all four [[warship]]s involved, with ''Callisto'' disabled by the destroyer {{UNSCShip|Las Vegas}} under the command of [[Lieutenant]] [[Preston Cole]].{{Ref/Reuse|he279}}

In [[2494|January 2494]],{{Ref/Reuse|mythos55}} the distant [[Outer Colony]] of [[Levosia]] in the [[26 Draconis system]] was suspected of diverting refined [[Wikipedia:Selenium|selenium]] and [[Wikipedia:Technetium|technetium]]—utilized in the manufacture of [[Shaw-Fujikawa Translight Engine]]s—to the [[black market]] to yield massive profits. Aside from lost taxes, the [[Unified Earth Government]] realized that it could not allow [[slipstream space]] engine components to fall into the hands of the growing [[Insurrectionist|rebellious]] factions throughout the Outer Colonies; in response, the [[United Nations Space Command]] sought to investigate the matter. The UNSC's [[Central Command]] ordered the [[UNSC Navy]] to blockade and search all ships in the 26 Draconis system for suspected contraband.{{Ref/Reuse|he279}}

The [[corvette]] {{UNSCShip|Callisto}} was patrolling the 26 Draconis system, when the corvette stopped and performed a routine inspection of a trading vessel by [[Naval boarding|boarding]] the ship and searching its cargo. The merchant crew of the vessel was nervous due to rumors of impressments during similar searches in the Outer Colonies. Some at [[Office of Naval Intelligence|ONI]] would later suspect that this rumour was deliberately started by rebel sympathizers.{{Ref|'''''[[Halo: Evolutions]]''' - [[The Impossible Life and the Possible Death of Preston J. Cole]]'', Section 4}} The inspection went tragically awry when a weapon was drawn and shots were exchanged, resulting in the deaths of three naval officers and twenty-seven merchant crewmen; no contraband was located on the trading vessel. This incident sparked outrage throughout the entire 26 Draconis system and the rest of the region.{{Ref/Reuse|mythos55}}

Thirty-seven days later, ''Callisto'' ordered a similar merchant ship to stand by and allow an inspection and the crew of the trading vessel courteously allowed naval officers to board. However, when the officers entered the cargo bay, they found it empty. Suddenly, the [[Blast door|bay doors]] opened and the officers were ejected into space. The "merchant" crew then boarded the unsuspecting ''Callisto'' and murdered the remainder of her crew.{{Ref/Reuse|he279}} ''Callisto'' was now hijacked by local [[terrorist]]s,{{Ref/Reuse|mythos55}} with her computer system gutted and replaced.{{Ref/Reuse|he279}} As the terrorists began using ''Callisto'' against UNSC forces in the system, the UNSC responded aggressively,{{Ref/Reuse|mythos55}} sending a [[battle group]] of three [[Unidentified UNSC light destroyer class|light destroyers]] tasked with locating ''Callisto''. The battle group was led by [[Captain]] [[Harold Lewis]] of {{UNSCShip|Las Vegas}}, and also consisted of {{UNSCShip|Buenos Aires}} and {{UNSCShip|Jericho}}.{{Ref/Reuse|he279}}

On [[2494|March 2, 2494]], ''Las Vegas'', ''Buenos Aires'', and ''Jericho'' arrived in the 26 Draconis system; the battle group soon located ''Callisto'' at 0315 [[Military Standard Time|MST]]. Realizing that the UNSC ships had located them, the rebels aboard ''Callisto'' moved the corvette towards a nearby [[asteroid]] field. Captain Lewis and [[Commander]] [[Rinkishale]] of ''Las Vegas'' determined that they needed to engage the corvette before she entered the asteroid field, otherwise ''Callisto'' would be able to "''play cat and mouse''" with the UNSC battle group. As ''Callisto'' neared the field, the corvette slowed and allowed the battle group to catch up. Lewis had all three destroyers in the battle group prepare to fire six of their seven [[Ares missile]]s at ''Callisto'' once they were within range. At 0317 MST, the battle group fired eighteen missiles at ''Callisto'' as the corvette advanced towards a city-sized asteroid. Suddenly, the corvette rolled and executed a slingshot orbit to the far side of the asteroid. As the missiles recalculated their targeting solutions around the rock, a [[nuclear weapon]] preemptively placed inside the asteroid detonated and blew the rock apart, destroying the missiles and launching debris towards the battle group. ''Buenos Aires'', having been the forward-most ship, was obliterated, while ''Jericho'' was damaged and ''Las Vegas'' was hit by a glancing blow that crumpled her hull. The damage ''Las Vegas'' sustained killed Lewis, Rinkishale, and the rest of the [[bridge]] crew except for [[Lieutenant]]s [[Preston Cole]] and [[Jorgenson]], though the latter was rendered unconscious. ''Callisto'', unscathed, angled out of the asteroid field and turned to face the remaining UNSC [[warship]]s.{{Ref/Reuse|he279}}

''Callisto'' engaged ''Jericho'', and the two ships exchanged missile fire, before the corvette succeeded in disabling the destroyer. Meanwhile, aboard ''Las Vegas'', Cole ordered all surviving crew members to the bridge. However, ''Callisto'' soon fired a missile upon ''Las Vegas'', disabling the destroyer. At 0348 MST, as per [[MIL JAG Order TR-19428-P]], Cole took command of ''Las Vegas'' as the destroyer sat dead in space. Knowing that the insurgents would be unable to resist capturing a destroyer, Cole signaled the unconditional surrender of ''Las Vegas'' to ''Callisto'' and requested immediate aid for the wounded. As ''Callisto'' docked with ''Las Vegas'', the insurgents offered to evacuate the injured to [[Lawrence Space Station]] if the crew of ''Las Vegas'' offered no resistance; Cole accepted. However, he had earlier ordered the crewmen to remove the ship's last Ares missile from its silo and transport it to the cargo bay ''Callisto'' was to dock with. Cole had the missile fired directly into the corvette, crippling ''Callisto'' and forcing her surrender.{{Ref/Reuse|he279}}

Following the ''Callisto'' Incident, the UNSC began to crack down on dissent throughout the territory, sparking rebellion throughout the Outer Colonies. It would be the ''Callisto'' Incident that sparked the [[Insurrection]], a massive civil war that waged across the [[human colonies]].{{Ref/Reuse|mythos55}} The incident had woken [[human]]ity from "complacency", as both the UNSC and the various insurgent factions began fighting and learning various tactics of [[space warfare]], which had been largely hypothetical up until this point. The fact that the Levosia terrorists had realized that nuclear weapons were not as effective in space, and instead planted a device within an asteroid to provide reactive mass to destroy one UNSC warship and cripple two others was noted to be a surprisingly intelligent tactic.{{Ref/Reuse|he279}}

Preston Cole's actions during the ''Callisto'' Incident were also considered a tactical leap of insight. Cole had faked a distress signal to lure ''Callisto'' closer to ''Las Vegas'' to allow him to cripple the corvette, however the action was a severe breach of [[Common Space Law]]. UNSC Central Command dithered over whether to award him the [[Legion of Honor]] or to have him [[court-martial]]ed. Ultimately, Central Command did neither to avoid setting a difficult precedent. However, from that point on, Cole could never again send a distress signal in enemy territory; he suspected that no one would believe it. Cole was quickly promoted, though not without protest, and later further promoted to commander and given command of a small corvette to patrol the Outer Colonies.{{Ref/Reuse|he279}}
