Commonwealth-Yaanari Intervention War

Declared not long after the 2nd. Battle of Avaconea, the **Commonwealth-Yaanari Intervention War** was a conflict initiated due to the direct pressure imposed by the defeats of the Galactic Entente at the hands of the Yaanari League. The war involved only the Commonwealth and the Yaanari nation, who had been targeted by the human-led nation as the aggressors of the 2nd. Yaanari-Entente War, in 2291. Seeing the war going poorly for the Entente, the Commonwealth mobilised its forces and attacked the Yaanari before any peace negotiations could be settled between both alliances, giving way to the Commonwealth-Yaanari Intervention War.

Starting on March 27th. 2296, the conflict also included the goal to liberate Billions of Uri citizens enslaved in Yaanari territory. Overall, the Commonwealth’s war demands included: The liberations of the Uri planets of Naff’Sewa and Ur Idra, the conquests of the Yaanari planets of Thrus-Sanguur and Frishac, and the deactivation of the Yaanari frontier outpost on the Kandauri System. After hostilities were officialised, Task Force Manticore and the reformed Commonwealth Army moved in to invade the Yaanari League, resulting in the battles of Thrus-Sanguur, Ebucrosie and Frishac. Amidst the fighting, an entity known as the Wraith of Fulaz appeared in Commonwealth territory, forcing Task Force Manticore to retreat and partake in the Hunt of the Wraith amidst its campaign in the war. Once the fleet had been repaired and could return to relieve Frishac of the Yaanari bombardment, the Yaanari League negotiated a conditional surrender with the Commonwealth, signalling the end to the conflict on July 14th, 2301.

Although a complete Commonwealth victory, diplomatically, it was perceived with a controversial gaze. Despite proven decisive during the confrontations, the efforts of the human-led nation ended up seeming far more like an opportunistic land-grab policy rather than any direct support to the battered Galactic Entente, who were forced to continue to fight on and eventually to sign a mere ‘white peace’, in 2305, with its Yaanari invaders. The event sorrowed relations between the Commonwealth and the federation, and although the league had been severely weakened due to the war, the Commonwealth would end up losing one of its conquered worlds due to high unrest and a subsequent annexation by the Yaanari League, an event today known as the Revolt of Thrus-Sanguur. Riddled with controversy and a myriad of diplomatic failures somewhat overshadowing military victories, the *Intervention War* remains an important event, celebrated by the Uri people and deeply studied by Yaanari citizens of today’s Commonwealth.

## **Prelude**

As the Commonwealth neared a decade of peace and economic growth after conflicts such as the 9 Month’s War and the Great Southeastern War, its neighbours still had their own shares of disputes left to settle with themselves. Down South, the Galactic Entente had been the target of a surprise invasion by the Yaanari League, in 2291, and had suffered a series of defeats that weakened its geopolitical stance against other threats such as the Thadrakos or the Mirovandians. Forced to partake in the 2nd. Battle of Avaconea, the Entente fleet - Led by Admiral Sacoterum cur'Vandom - was defeated and bruised, forced to retreat and thus leaving the gateway to the Alir core worlds open for Yaanari incursions. Reinvigorated after their humiliating defeats from the Great Southeastern Wars, the Yaanari League pressed on its advantage, driving the Entente coalition warships back and creating a distraction for the Mirovandian side of the Regal Axis to strike from behind.

Watching these events unfold from afar, the Commonwealth initiates a session of voting in parliament to officially declare war on the Yaanari League. Having learned its lessons from the Battle of Voice, the army had undergone through a series of changes that made it smaller, more effective and considerably more professional than it was before. Task Force Manticore also received a series of upgrades and bigger, more powerful vessels since the Great Southeastern War, the newly-commissioned Poniatowski-class Battleships being a clear example of their economic growth since the 2260s. After some weeks of voting, Parliament passed its resolution, allowing for war to be declared on the Yaanari League on March 27th. 2296.

## **Conflict**

Once finally into effect, the hostilities were firstly shown by Task Force Manticore’s encroachment on the Ebucrosie System later that year. Amidst the conflict, and, knowing the troublesome cultural shock between Human and Yaanari societies, the Commonwealth’s Prime Minister at the time, Takumi Ishii, drafted the Land Appropriation Act, a measure taken to deport unruly Yaanari individuals who would not comply to Commonwealth laws once the claimed worlds were annexed; In October, parliament passed the bill with a 4 to 1 approval ratio. Several months later, after a severe bombardment campaign undergone by Task Force Manticore, forces under command of General Lop Aspinaca landed on the planet of Thrus-Sanguur, giving way to the Battle of Thrus-Sanguur in early 2298. Afterwards, going against orders of his superiors, the general authorised the lending of arms to several freed Yaanari slave militias for the defence of the planet, either against Yaanari counter-attacks or general popular uprisings sowed by the unrest of the invasion. With its first world secured, the invading forces could now venture deeper into Yaanari territory without risking an envelopment from behind.

Capitalising on their gains, Task Force Manticore ventured deeper into Yaanari systems, a move which left the Ebucrosie System unguarded. Seeing the opportunity, the Yaanari Gror’cash Star Hunters exploited the vacuum of opposition to warp into the system and lay siege to Thrus-Sanguur, in an event which disgruntled the planetary population even further, and forced the Commonwealth forces to hunker down until reinforcements arrived. Seeing their trap work as intended, Admiral Satayesh Ibrahim moved her fleet back to the system and plotted a course directly towards the Yaanari fleet over the besieged planet. The Gror’cash Star Hunters moved to engage, leading to the Battle of Ebucrosie - A resounding Commonwealth victory.

In November of 2299, the Battle of Frishac was fought, bringing another Yaanari planet to Commonwealth control. By the following year, however, the situation within the nation had changed, for the Wraith had appeared on the Fulaz System. Tasked with hunting the creature, Task Force Manticore and the recently formed Task Force Archon were recalled from their offensives and forced to leave the front for the foreseeable future.

Once the Commonwealth Navy had returned from their unexpected campaign to hunt the wraith, they found that the war had changed little since they were forced to leave. After arriving at the Avaconea system, to relieve the Army from heavy Yaanari bombardment at Frishac, Task Force Manticore was instead approached by a Yaanari vessel, containing diplomats that proposed a conditional surrender to the Commonwealth leadership. Over the following days, the negotiations were settled, and the war had come to a close as a resounding Commonwealth victory.

On July of 2301, the Yaanari League admits defeat and surrender unconditionally to the Commonwealth, agreeing to the proposed **Treaty of Frishac**;

* Thrus-Sanguur is annexed by the Commonwealth.
* Frishac is annexed by the Commonwealth.
* Naff’Sewa is liberated and ceded to the Commonwealth.
* Ur Idra is liberated and ceded to the Commonwealth.
* The Yanaari frontier station in the Kandauri System is dismantled, forcing the nation to abandon the local area.
* 10 years of truce between the Commonwealth & Yaanari League, preventing any aggression between both parties officially.

## **Aftermath**

The war, although over, continued to rage on despite the so-called conditional peace agreed by the Yaanari. In the South, the federal fleet of the Galactic Entente continued its scramble to refurbish itself, as its ‘ally’ had left the war as soon as it swooped in, taking the Yaanari fleet out, at the very least. Meanwhile, the Commonwealth had issues of its own when faced with the occupation of Thrus-Sanguur. The population had been rioting intensely despite the end to the conflict, and before army forces could be transferred to the planet from Frishac, a full-blown revolution had erupted in 2302. As violence spiralled out of control, and as those same armed slave militias switched sides and attacked Commonwealth soldiers midway through firefights, the small contingent of the army retreated from Thrus-Sanguur, leaving the Yaanari rebels victorious once combat had ceased in April. Weeks later, as the Commonwealth geared its forces to retake the rogue planet, the Yaanari League swooped in and annexed the recently proclaimed republic, in a blalant land-grab which was then a target of loud denunciations from the Commonwealth and its diplomatic corps.

Unfortunately, for them, the recent Treaty of Frishac prohibited any form of official action translated as acts of hostility against the Yaanari League, meaning that the rebel instigators had essentially come out unmolested from their insurrection against the Commonwealth, only to then be reintegrated to the Yaanari government. Despite a wave of diplomatic threats, there were little allies in which the Commonwealth could rely on to back up their claims; The Entente was already at war with the Regal Axis, and after the human exit from the war, were on worse-off on diplomatic terms than before, meanwhile the Udkavongo had also began distancing themselves from the Commonwealth, and although the Thadrakos reasoned with the numerous denunciations conducted by the outraged humans, their words amounted to nothing when compared to their undercover trading with the Yaanari League. For the time being, it seemed like the Commonwealth would have to swallow its pride and await another opportunity to strike the Yaanari - And strike them for good, when that time came.
