Operation: FIRST STRIKE
From Halopedia, the Halo wiki
Operation: FIRST STRIKE was a raid by the survivors of the Battle of Reach on the Covenant space station Unyielding Hierophant. It was the largest UNSC victory after the Battle of Sigma Octanus IV.
History
Background
Having discovered the location of Earth from a Forerunner artifact recovered from Sigma Octanus IV, the Covenant built up a massive invasion fleet over five hundred ships strong to assault their target. After discovering the plan from a captured VCovenat A.I, Cortana and John-117 formulated a counter-plan that result in either a massive victory or the deaths of every SPARTAN.
The Raid
In a desperate attempt to stop a massive Covenant armada heading for Earth, five Spartans infiltrated the Covenant battlestation Unyielding Hierophant onboard a captured Spirit dropship. This was the first Spartan encounter with Brutes, who guarded a temple in an Atrium-like structure in the battlestation. One of the Spartan-IIs, Grace-093, was killed by a Brute Shot and COM triangulation tactics. The Spartans fought their way to a reactor room and set the generators to overload. Once the reactors were set to overload, the Spartans returned to the Atrium-like room, opened the airlocks, and blew out a shield-like structure that enclosed the Atrium. One of Cortana's clones was taken along and had to open the airlocks for the Spartans. Her copy of a copy in the Covenant network was discovered and forced to make hundreds of copies to protect herself. She sucessfuly opened the airlocks and tied up the Covenant's communication by repeating error messages on their COM systems endlessly. The Spartans then traveled to the far side of a nearby moon and unexpectedly met the UNSC Gettysburg. Vice Admiral Danforth Whitcomb and Lieutenant Elias Haverson took the Ascendant Justice and crashed into the Unyielding Hierophant. Whitcomb pretended to have the Forerunner Crystal on board the ship (using a hologram), challenging all the Covenant in the system to try and take it from him. The Covenant battleships all gathered around the Ascendant Justice and the overloading battlestation, attempting to take the Crystal from Whitcomb. The battlestation then overloaded and exploded, killing the Vice Admiral and Lieutenant, destroying most of the Covenant fleet, and saving Earth from an unexpected strike.
The outcome and historical result of the battle was very important and noteworthy as the Covenant did not yet know the strategic importance of their intended and vectored target. Thus, their actual first entrance into the Sol System was with a much smaller force than the pre-fated Reach. This was crucial to the survival of the human homeworld and the significant UNSC presence on Earth.
