Harvest all the way up to the Battle of Earth

2525

February 3, Harvest:
The Harvest orbital platform made long range radar contact with an object. It was made of an unknown material. Contact with Harvest was lost shortly thereafter.

April 20, The Argo:
Sent by the Colonial Military Administration to investigate the loss of contact with Harvest, the scout ship Argo arrived in-system on 20 April. Other than a brief transmission to confirm their exit Slipstream position no further reports were made.



2525

October 7, Contact:
Fleet Command assembled a battlegroup to investigate and they enter the Harvest system on 7 October. The battlegroup consisted of the destroyer Heracles, commanded by Captain Veredi, as well as the frigates Arabia and Vostok.

They discovered drastic changes to the planet Harvest’s surface and no sign of the three million colonists. An alien ship was detected in orbit. The ship did not attack until Captain Veredi tried to initiate communications. They responded by broadcasting the following message in the clear, in our own language: “Your destruction is the will of the Gods…and we are their instrument.”

The Vostok and Arabia were lost with all hands while the Heracles jumped out of the system, but took several weeks to return to Reach due to damage sustained in the battle.

November 1, War:
The UNSC is placed on full alert. Vice Admiral Preston Cole is mobilizing the largest fleet action in human history to retake the Harvest System and confront this new threat.

The Spartan II program is accelerated to help deal with the new Covenant threat.



2531

The Battle of Harvest:
Admiral Cole's war fleet engages the alien warship responsible for the decimation of the colony, scoring a victory (though the battle cost Cole two-thirds of his battle group). Only a last minute tactical inspiration turned the tide of battle. After returning to Earth, Cole-promoted to Admiral-learns that a number of outlying colonies have been destroyed, leaving behind no survivors. Cole begins to move his fleet around, trying to intercept the invaders. Ground and ship-to-ship battles begin in earnest, raging throughout the Outer Colonies. During one ground engagement, Human forces capture one of the aliens. Before succumbing to his wounds, interrogators learn that the aliens refer to themselves as "the Covenant" (roughly translated).

The Outer Colony Massacres:
Over the next four years, Cole's forces were hammered, despite his excellent leadership and tactical brilliance. It was simply a matter of being outgunned; Covenant kill ratios tend to top four to one in ship-to-ship combat.

By November of 2535, virtually all of the Outer Colony worlds had been destroyed by the Covenant. The "Cole Protocol" was established by military order: All human vessels must ensure that Covenant forces do not find Earth. Human ships—when forced to withdraw—must not travel on an Earth-bound vector, even if that requires jumping into Slipspace without proper navigational calculations.

If blind jumps are not possible, the ship's captain must order self-destruction if capture is imminent. In addition, it is also imperative that the powerful ship AI data cores not fall into Covenant hands, so part of this protocol involved either the removal or destruction of the ship's AI in extreme situations.


2536-2552

The Siege of the Inner Colonies:
Covenant forces swarmed into the Inner Colonies. For several years the war fell into a pattern: humans emerged victorious from isolated battles—typically during ground operations—but at a horrible cost. In space combat, the humans lost at a precipitous rate, and one by one, the colonies fell.



2552

Halo:
Covenant forces arrived at Reach and obliterated Earth's last major military stronghold. The battered cruiser, the Pillar of Autumn, fled the devastation, carrying with it the sole surviving SPARTAN. The SPARTANs—an elite unit of supercommandoes, equipped with the fearsome MJOLNIR assault armor—were created as the ultimate soldiers.

Now, only one SPARTAN remains to carry the fight to the enemy. In accordance with the Cole Protocol, Captain Jacob Keyes—the Autumn's commanding officer—plotted a random, long-distance jump, hoping to lure the Covenant fleet away from Earth.

After deactivating the drive, the Autumn dropped into a distant, uncharted system. There was a Covenant fleet in the system as well, near a planet-sized ring-shaped construct, "Halo."

When the Covenant reached ''Halo'' they somehow activated a long range FTL drive. When the Covenant went through the the Autumn was right behind them but, when they were about to go into slipspace The Spirit of Fire came out of slipspace and opened fire with there port cannons on the Covenant ship. The Covenant ship was damaged but not bad enough that it crashed. The Autumn and the Covenant went through. The Spirit of Fire accelerated its engines to melting point until they made it to the portal before it closed.

When they exited slipspace, every human being on board was appalled to see that the Covenant had found Earth..and they were opening fire. The Autumn and Spirit of Fire immediately intercepted.
But even with the planet-breaking attack that the UNSC were showering on the Covenant, it still did its damage. The whole northern hemisphere was ablaze, the ocean was boiling, the ground imploding on itself...

Admiral Cole made a pin point decision. He told his on board A.I Tabitha, to plot a course for the Covenant ship..His exact words were, ``Were not going out without taking you scum with us!``.
The Covenant were too busy killing Earth that they didnt see the Autumn until she was right on top of them.

There was a deafening crack then a implosion. But it wasnt the Covenant ship...it was Earth. Earth's core was so dense that it imploded on itself..Spirit of Fire was forced to retreat. They entered slipspace and exited 3 hours later in the Andromeda Galaxy. No one knows what happened to Admiral Cole and the The Pillar of Autumn after that.

Since there was no where else to go back to Cryogenic Freezing took effect. The on board A.I Serina was ordered to scan for Earth like planets then awake either him or Anders. After 10 years Serina found a planet with breathable air and it was actually larger than Earth. When they landed all hands were awake and ready for action. Thankfully there wasnt any, as they landed the crew rejoiced to find that there were actually Earth like structures on this planet.

10 years later and now that new found planet is called Hype and its the new Earth.
