The Hungary-Austria War took place between November 18th, and November 21st, 2009.
Negotiations had been ongoing between Austria and Hungary to close the open state of war since Austria regained all of its original regions in early September, 2009. Though the open war had been used for landswaps and other strategic purposes, rather than for hostile reasons - and both nations were in PEACE GC - there was a growing concern in Austria that it may be used by Hungary in order to take Burgenland. Hungary's unwillingness to close the war, as such, merely grew suspicions. Additionally, two growing sentiments set Austria and Hungary at odds. In Hungary, support for expansionism in general, and into Burgenland in particular, began to grow. These views were shared by Hungary's President, Termetes Samu. Also at the same time, Austria and France had grown increasingly close due to the anti-imperialist views held by President Lyne Faynel of France, and Rangeley of Austria.
On November 16th, Hungary withdrew from PEACE GC, and the next day requested Austrian help for the ongoing Hungarian invasion of Slovakia in the form of passage through Austria. The Austrian government, which had called for a Hungarian withdrawal just days earlier, refused to aid in the occupation.
Having been rejected, the Hungarian government entered a period of division about whether to go forward with the plan. Termetes Samu continued to support the concept, and ultimately launched the invasion into Burgenland.
Battle of Burgenland
The battle opened in the afternoon of November 18th, and Austria was quickly outmatched militarilly. With Hungary having over 14,000 citizens to Austria's 400, the battle easilly went into the underground. France and Malaysia, who had MPP access to the battle, joined the battle on behalf of Austria, and the Austrian government worked to secure the support of other nations. Oraizan, then acting in an advisory role to President Rangeley of Austria, spearheaded the diplomatic effort to get EDEN as well as PEACE GC on board. Alfred Ball, General of the Austrian Army, was tasked with the military effort of organizing Austrian forces for the defense. Meanwhile, President Rangeley called on all Austrian's to resist invasion "not only for ourselves, but for every nation, and their sovereign right to independence. Their right to lead their nation the way they desire. Their right to pursue peace. And their right to stand up to those who so cowardly wield their might, knowing full well that they can convince noone otherwise to support them."
Into day two of the war, several more nations had joined on behalf of Austria, notably including Canada who moved a large part of their mobile corps to fight. In Hungary, debate and disagreement began to grow, casting doubt on the level of support that the invasion actually possessed domestically, which was compounded by an inability to secure international support.
As the battle began to wind down, an array of nations had thrown their support behind Austria, including both alliances of PEACE GC and EDEN. Nonetheless, the battle remained over 100,000 in the underground. Austria's government authorized funds for late tanking by both France and the PeaceKeepers. Ultimately, they were joined by elements of the Hungarian army that was opposed to the invasion - who fought against their own nation. In the end, the battle was a surprising victory for Austria against the much stronger Hungary.
Battle of Bratislava
With the Battle of Burgenland having been won, but tensions not yet having dissipated, both PEACE GC and EDEN desired to turn the tables on Hungary by attempting to liberate Slovakia from Hungarian occupation. The Austrian government consented to join the effort, and opened a blocking battle against Hungary in Bratislava. No major tanking was authorized, in contrast to the earlier battle - and though the battle itself would not be won, two other Slovakian regions were liberated by other forces.
With Austria in possession of all original regions, and Hungary having lost two Slovakian regions since the war began, there was a push to oust Termetes Samu from the Hungarian Presidency. Though the impeachment effort failed, he nonetheless stepped down and handed power over to an interim government, remarking "my decision was not careful enough, not counting all aspects of the consequences." Negotiations organized by former Austrian President Metallon were held between former Hungarian President Feherlofia Koppany, representing Hungary diplomatically, and Austrian President Rangeley, which secured terms for a ceasefire and end to the conflict. Both nations agreed to take no further hostile actions against one another.
With an end to the conflict successfully negotiated, relations between Austria and Hungary began to be repaired - however, the closing of the state of war did not materialize. Fighting would not re-ignite between the two nations - and eventually, the last Slovakian region - Bratislava - was returned to Slovakia by a later resistance war. Within Hungary, expansionist desires involving Burgenland would fade for a time. In Austria, a return to peace was welcomed. Oraizan would go on to become Chief of Staff after Rangeley's re-election to the Presidency in December, while Alfred Ball would be promoted to Minister of Defense in recognition of his work.
