The **Second Extrasolar War** also known as the **Second Helghan War** was the second major war between the ISA/UCN and the Helghast.

The War was known to last a grand total of over 37 years before finally coming to an end on December 30th, 2394.

The war began on August 11th, 2357 when the Helghan Empire, under the control of Scolar Visari, sought to dramatically expand itself by invading Vekta, then invading Earth once Vekta was conquered, and destroying the UCN. Any opposition from the ISA-controlled systems would be crushed in a subsequent invasion of all other Human colonies.

## History

### Invasion of Vekta

The first stage in the Helghast's expansionist plans was the reclamation of the ISA controlled world of Vekta. Initially the ISA suffered massive casualties and territorial losses on Vekta after the Orbital Defence Systems 'malfunctioned', opening up the planet to a mass invasion force, and with a pair of high ranking double agents, the Helghast managed to take large swaths of territory and inflict severe ISA casualties in a savage blitzkrieg.

despite intense and harsh actions of Jan Templar and UCN reinforcements, the invasion succeeded and the Helghast occupied Vekta, leaving only one ship that survived the Earth Fleet's destruction.

### Post Vekta

Days after Vekta, celebration was conducted all over Helghan following the Helghast victory of reclaiming the former colony that was lost back at the time of the First Extrasolar War, where not long after Scolar Visari had passed down command of Vekta to General Lente of the Third Army, who in turn killed ISA Traitor General Stuart Adams In front of the people of Helghan after his usefulness had been completed, and his body had been disposed of in the wastelands of Helghan.

News of Vekta's fall quickly stirred shock amongst the Earth Colonies as the UCA prepared for a counter offensive in hopes of reclaiming Vekta.

However due to the sudden declaration of war that was sparked by Helghan, and the immieadely elimination of the Earth Fleet that was sent to reinforce Vekta thanks to Adam's SD Platform hijacking, the UCA was delayed in their counter attack due to them having to recover from the losses sustained during Helghan, however ISA planets that were near Vekta had managed to gather a large fleet together in hopes of launching a full scale counter attack against Vekta on August 29th, 2357, however Visari expecting such an attack sent a fleet of his own in order to blockade Vekta in order to wait for the assault to occur, while also reinforcing the Third Army on the surface of Vekta with the 7th and 2nd Armies.

By September 5th, 2357 a fleet of over 445 ISA Cruisers departed the planets Monastary, Aliosho and Aegis for Vekta just 4 days before the arrival of Helghast reinforcements on Vekta by September 9th, 2357.

#### ISA Counterattack

The first wave of the ISA fleet arrived at Vekta on September 12th, 2357 where they clashed against the Helghast blockade over control of Vekta's orbit.

During the early stages of the Space engagement conducted by both the Helghast and the ISA, the Helghast with the use of the SD Platform was able to inflict heavy losses on the ISA Fleet, prompting ISA bordering teams to try and launch out from their cruisers in hoping of recapturing the SD Platform and turn them against the Helghast blockade.

As more ISA ships arrived in Vekta's orbit the battle intensified into the largest Space engagement to ever occur in the history of the 24th Century, while also involving a defense station. Despite severe resistance conducted by the Heglhast fleet, the constant arriving of wave after wave of ISA Ships coming out of hyper space eventually forced a massive break through allowing ISA forces to land troops on Vekta by September 14th, 2357, where they would engage against the Helghast Third Seventh and Second Armies beginning the ground theater of the Second Battle of Vekta.

While the war on the ground was conducted, the ISA at one point were successfully able to attack and destroy the Helghast at the battle of Fort Arcgor, resulting into Jan Templar escaping Helghast custody and joining the ISA in the counter offensive against the Helghast on the ground. During the course of the ground campaign Templar was also able to free both Hakaha, Rico and Luger from the Helghast as well allowing the 4 man squad that once battle the Helghast during the Invasion of Vekta to be reunited once again on September 15th, 2357.

Despite the ground war going well for the ISA, the war in space started to take a heavy toll when more Helghast reinforcements arrived from Helghan further allowing the Helghast fleet to turn the tide in the war in space by September 16th, 2357, allowing them to close the gap that led to Vekta's surface preventing the ISA armada in space from sending more troops down to Vekta, and trapping the ISA ground forces on the planet, however the balance of power once again fell to the ISA, after Templer and his squad was able to reach the Uplink and smuggle aboard the Helghast controlled SD Platform, and secure the sattelite with the aide of ISA Space Marines that were pinned down by Third Army soldiers.

As the ISA now had control of the SD Platform, the ISA used the platform in order to target incoming Helghast vessels that were coming in from Hyperspace from Helghan, this in turn would force the Helghast to scuttle SD forcing Templer's squad and ISA to abandon the platform, where their pods would crash back down to Vekta's surface.

As the War in Space hit a critical turning point with the remainder of the ISA ships slowly starting to diminish due to more Helghast ships coming from Helghan, the ISA Ground war on Vekta began to take a bad toll as the Third Army was able to destroy a vital supply line that was keeping the ISA Ground Invasion alive at the Battle of Kellin Ridge, thus allowing the Helghast Third 2nd and 7th Armies to over run and reclaim control of the areas on Vekta that they had lost in the last 3 days.

With heavy losses mounting, and more Helghast ships coming in, the ISA remaining forces abandoned Vekta and fled back to Aliosho, ending their attempted offensive and failing to reclaim Vekta.

### Operation Vengeance

The failed ISA counter offensive to reclaim Vekta that occured from September 12th, to September 16th, 2357, had managed to severely conduct a harsh blow to the ISA strength within the Alpha Centuari System, thus allowing Scolar Visari to move forward with the second stage of his plans, which would be known as the Helghast Journey to Earth.

With the UCA still not fully recovered from the Invasion of Vekta, and Vekta alone now being fully under Helghast rule with no possible chances of ISA attacks, the full might of the Helghast Empire was unleashed on the Alpha Centuari System in hopes of gaining more planets and resources in order to fund Visari's War effort in the drive towards the Solar System.

By September 20th, 2357 Scolar Visari declared that the massive Helghast journey towards Earth has now begun, where the Helghast blitzing of the Alpha Centaury System would be codenamed Operation Vengeance, a codename to identify the Helghast's attempt at gaining territories in the Alpha Centauri System in order to begin the great offensive towards the Solar System.

#### Invasion of Monastary

During the course of Operation Vengeance, the Helghast Empire divided its Blitz into multiple groups in order to assault and Invade 7 different planets within the Alpha Centauri System, where the ISA were mostly weak and battered following the failed offensive against Vekta.

On September 30th, 2357 the Helghast Invaded Monastary, one of the planets responsible for launching the Failed counter offensive against Vekta.

During the course of the Invasion, despite severe ISA resistance along with a few reinforcements coming in from Willard, the ISA were completely unprepared for the Helghast retaliatory Invasion thus resulting into the planets downfall on November 14th, 2357, allowing the Helghast Empire to conquer the first planet ever in the Second Extrasolar War following Vekta and the initiation of Operation Vengeance.

#### First Battle of Nygir

Despite the series of engagements that was occurring during the time of Operation Vengeance, the Nygir Moon which orbited Monstary during the Monstary Engagement was landed upon by the Helghan 3rd Space Battalion which planned to occupy the Moon of Nygir in hopes of being able to provide orbital support for the Helghast Forces on the surface of Monstary at the time of the Invasion of Monstary.

A large space engagement occured on September 25th, 2357 between the ISA and Helghast fleets for control of Nygir's airspace, where despite the ISA fleet being outnumbered and outgunned, the use of SD Platforms prevented the Helghast fleet from reaching the moon and forcing them to turn around.

It would eventually be from the Nygir moon where ISA reinforcements would be sent in to aide the exhausted ISA forces on the surface of Monstary throughout the rest of the Monstary campaign.

#### Second Battle of Nygir

After Monstary had fallen on November 4th, 2357, all remaining ISA space forces chose to make one final stand for the planet on Monstary's moon of Nygir, beginning the Second Battle of Nygir on November 7th, 2357.

Despite reinforcing the Moon's defenses, the Helghast was able to attack the ISA Fleet in the same manor that they conducted during the first official engagement, however during the course of the Second Battle of Nygir, a weak spot was revealed in the ISA lines thus allowing the Helghast to break through the SD Platform lines and allowing the Helghast to Invade the Moon where by November 8th, 2357, the Helghast would destroy the remaining ISA resistance left on Nygir, completely conquering Monstary completely.
