In 1932, the Kadelburg Empire would join a supposedly short war the Zasnyan Empire was fighting against the Kingdom of Druavania, which would catch the attention of pretty much the entire world. The Vebrus Empire would respond to this by increasing the number of units on their borders, which then quickly escalated into a border skirmish that killed a Kadelburian officer and his driver while they were driving to a checkpoint. The Kadelburians declared war, Vebrus called the support of The Commonwealth, who dragged the Republic of Montagne Bleue and Roosenvard into the war. It started out like any other war, firing and maneuvering, but it was slowing down and so both sides dug in, starting trench warfare. Trench warfare would start in the east a few months later too, and brutal battles for no gains were commonplace.
The Union of Estroycor were supply the Commonwealth with much needed equipment, and one day a civilian ship was struck by a Kadelburian submarine's torpedo, which sunk the ship and killed all 500 people onboard. The Union declared war, sent a million troops on their way to the frontlines over the oceans and join the trench warfare themselves. The Union's presence increased morale, sure, but they were eventually bogged down too. Then, the Zasnyans thought it would be a good idea to invade the nearby kingdom of Ujedinjena Slavija, but that resulted in their former ally Repubbliche Unite siding with the Commonwealth's faction and fighting in the mountains began. Meanwhile, The Kingdom of Aspana decides to send a volunteer force to the Kadelburians, this force would later become the Blau Division. Then, Estroycorian forces launched a massive offensive, breaking through a major Kadelburian defensive line and sending the armies retreating to higher ground. The Commonwealth would then deploy the first heavy armored vehicle (codename "Watertank") to the front, making more breakthroughs, but this new enemy defense wasn't going to fall that easily. The Commonwealth calls on the Kingdom of Brandriet to join the war, which is responded with by a telegraph message: "Yes."
The Brandrietians have joined the war, and quickly troops are sent to the front, while a specific division was sent to the East to assist the Vebrusian, that division was the 7th Infantry Division (7e Infanterie Divisie). The front on the West draws to a stalemate while the front in the East is heavily unstable and moving... a lot. Too much, because both sides in the East are getting confused on who has occupied what. This becomes into a mass retreat... by both sides. Never knew Vebrusians would cause that much confusion amongst both themselves and the enemy, but oh well. Repubbliche Unite then launches a mountain assault on the Zasnyan forces, which turns into a stalemate that'd eventually devolve into LITERALLY 20 BATTLES. No joke, it's the Isonzo of this universe.
Then, one fateful morning, a telegraph was sent to Montagne high-command. Montange and Commonwealth colonies in Asia were being attacked by the Raijingusan No Teikoku's armies. And so, the Commonwealth's Australium Division and Montange Colonial Armies in Asia were to hold off said attacks for as long as possible. Micronesia was the first Montagne colony to fall, and then Burma and Vietnam. The Montagne were losing control of the situation quickly, having to rely on the Australium Division and other Commonwealth Colonial Armies such as the Rajian Division and 1st Singaporean Regiment. Then, Singapore was attacked by the Teikokuians and fell quickly, with a pocket of Commonwealth troops holding the capital buildings.
Back in the West, the 2nd Singaporean Regiment was sent to the Western Front. Now, "what's happening on the Eastern Front", none of you are asking. Well, the Vebursians finally got their act together and started advancing forwards... but for a bit before the front stalemated again until the Slavijans came to break through the stalemate.
Quick switch back to the Far-East, there's been new developments. The Luoyang Republic and their coalition of warlords and the Yellow Socialist Party have been invaded by the Teikokuians. Both armies resort to trench warfare, unlike the previous island-hoping and quick offensives the Teikokuians have done in the past.
Okay, BACK TO THE WEST. LIKE, NOW! The Commonwealth launches yet another offensive with armored vehicles and all that but get bogged down again. Just like last time.
And then something massive happened on the Eastern Front. At the same exact time the Vebrusians launched their "August Offensive," territories in Siberia and the Far-East broke off from the empire, forming The Socialist Republics of Vebrus (SRV), but for now they're called The Vebrusian Red Army (VRA). Siberians that didn't submit to the communist menace either were killed off, moved to imperial territories or joined the Vebrusian White Army.
