The Thalassan War was a continental war that lasted from 1941 to 1947, although related conflicts began earlier and were, in some places, resolved later. It involved the vast majority of the Thalassan nations. The war was fought between two major alliances. The Allied Powers, consisting of Andalla, Orioni, Manamana, and Iverica. The Matroilan Empire, consisting of Mat Troi Lan, Giokto, and Selayar.

The war began in 1941 when the Giokton Republic declared war on Andallan Commonwealth, and quickly escalated into a global conflict. The Matroilan Empire, under the leadership of Emperor Gabrielos, attempted to establish a "Greater Thalassan Co-Prosperity Sphere", and conquered most of the continent. However, the Allies were able to turn the tide of the war in 1946, and defeated the Matroilan Empire in 1947.

The aftermath of the war was significant. The Matroilan Empire was dissolved, and the Kingdom of the Sunset Sea Islands was established. Orioni and Iverica emerged as the two major powers in Thalassa. Andalla was granted control of Giokto, while Selayar was plunged into civil war. The war also had a profound impact on the global geopolitical landscape, and led to the development of new technologies, including nuclear weapons.

Background

On 30 July 1926 the Treaty of Protiva is signed, formally ending the First Giokto-Andallan War and granting Andalla control over the Giokton province of Liamchia (廉奢: Liâm-tsia). In 1939 a socialist-monarchist coup takes place in Selayar, with General Dharmasetu Sahaja ruling as absolute monarch.

Andalla

Andalla is a sovereign state located on the continent of Thalassa. It was founded in 1931, following the dissolution of the Andalla Commonwealth. The Commonwealth was a federal union of several states, including Andalla, Giokto, and Selayar. The dissolution of the Commonwealth was the result of a series of conflicts, including the First Giokto-Andallan War (1923-1925) and the Second Giokto-Andallan War (1927-1929). The new nation of Andalla was a parliamentary democracy. It quickly established itself as a major power in Thalassa,.

Selayar

Selayar is a country located on the continent of Thalassa. Prior to the 1939 coup, Selayar was a parliamentary democracy. However, the coup led by General Dharmasetu Sahaja, a charismatic and influential military leader, was swift and decisive. Selayar's democratic institutions were dismantled, and the new socialist regime quickly consolidated its power. The government implemented ambitious nationalization programs and Selayar underwent a period of rapid social and economic transformation.

Prior to the war, the Sunset Sea Islands were known as the “Empire of Mat Troi Lan”, which roughly translates to “Empire of the Setting Sun”. It was a sovereign state located in the Oriental Ocean. It was an expansionist empire, which grew in power and territory throughout the 1940s. It was notorious for its ruthless exploitation of the nations it conquered, including the lesser developed island nation of Shurui. It also claimed the Dobbarier Reef, going on to mercilessly exploit the nation for material gain. Their lands were pillaged to feed the population of Mat Troi Lan and their resources were taken to fuel the Imperial war machine, which increased its production of war ships and weapons dramatically.

When the original war-faring parties in Thalassa Andalla and Giokto were exhausted by years of armed combat, Matroilan took its chance to strike. By attacking the destroyed and weakened nations, Matroilan of Mat Troi Lan managed to spread its rule throughout the entire continent of Thalassa. To establish a "Greater Thalassan Co-Prosperity Sphere", Matroilan went after nations neighbouring the continent. "Co-Prosperity" was, naturally, not the goal of the campaign, but total economic exploitation of the continent for the benefit of Mat Troi Lan.

Giokto

Giokto (玉島保國: Gio̍k-tó) was a sovereign state located on the island of Giokto in the Thalassan Sea. It was a parliamentary democracy, and its territory encompassed the island of Giokto and the Goa Archipelago off the northwest coast of Giokto. Prior to the Thalassan War, Giokto was a close ally of Andalla. However, the war strained relations between the two nations, and Giokto eventually joined the Matroilan Empire in 1943. The Giokto military was one of the most powerful in the Thalassan War, and it played a significant role in the Matroilan Empire's conquests.

The Matroilan Empire began preparing for war in the years leading up to the Thalassan War. This included building up their military forces, expanding their territory, and developing alliances with other nations. Prior to the Thalassan War, the Matroilan Empire also engaged in a series of small-scale conflicts with neighbouring nations, such as Shurui and the Dobbarier Reef, to enhance its military experience and capabilities. It also expanded its territory by annexing the Dobbarier Reef.

In 1941, the Giokton submarine I-23 sank the Andallan troop transport SFS Teuvo Antonnen, killing 1,452 soldiers and crew.. Following the sinking of the SFS Teuvo Antonnen, after a speech by Andallan President Lars Nedergaard, Andalla's Kongres declared war on the Giokto Republic, and Protocol Shadow was enacted. This marked the official beginning of the Thalassan War. However, this declaration did not deter Matroilan from its own expansionist agenda.

The first major engagement of the Thalassan War was the Battle of Liamchia, which began on 19 November 1941. Codenamed Operation Lyn, the battle began with a massive Andallan artillery barrage and air assault. An hour later, Andallan tanks and APCs charge into the buffer zone and assault the Giokton fortifications, amid heavy shelling. With assistance from the Andallan Commonwealth Army Airborne Corps' Luftbårnejaegeren (Airborne Rangers), the Andallan military was able to neutralize most of the Giokton border emplacements, albeit at a very high price. The battle resulted in a tactical victory for Andalla, despite heavy casualties.

This marked a turning point in the Matroilan Empire's strategic calculus. This act of aggression provided Matroilan with the pretext it needed to intervene in the conflict between Andalla and Giokto. Despite the Battle of Liamchia, Matroilan saw the Andalla-Giokto War as an opportunity to expand its influence and power. The empire's covert preparation for conflict paid off, as it seized control of much of Thalassa and established itself as the dominant power in the region.

Tiauhai campaign

The Tiauhai Campaign (1942) marked a significant turning point in the Thalassan War. While the war had initially centred on the conflict between Andalla and Giokto, the Tiauhai Campaign expanded the war's reach and solidified Matroilan's dominance in the region. The Tiauhai Campaign was preceded by a series of local conflicts that had escalated into the Tiauhai Sea region. These conflicts had sapped the strength of both Andalla and Giokto, leaving them vulnerable to Matroilan's expansionist ambitions.

Sensing an opportunity, Matroilan intervened in the conflict, ostensibly as a peacemaker. However, its true intentions were to exploit the weakened state of Andalla and Giokto to expand its own territory. Despite the escalation of the conflict, none of the neighbouring Alharun and Aurealian states intervened militarily. This surprising neutrality can be attributed to a series of non-aggression pacts signed with Matroilan, motivated by fear or intimidation.

Under the guise of peacekeeping, Matroilan absorbed both Andalla and Giokto, effectively neutralizing its two main adversaries in the Thalassan War. This swift and decisive action demonstrated Matroilan's military prowess and its willingness to use force to achieve its objectives. MTL's expansionist ambitions did not stop at Andalla and Giokto. In the Autumn of 1942, Matroilan troops landed on and occupied Burkini. This move further solidified Matroilan's control over the region and demonstrated its determination to establish itself as the dominant power in Thalassa.

The Tiauhai Campaign had a profound impact on the Thalassan War and the region as a whole. It marked the beginning of Matroilan's rise to regional dominance, with the empire absorbing Andalla, Giokto, and Burkini. The campaign also highlighted the vulnerability of the neighbouring states, who were forced to remain neutral for fear of Matroilan's aggression.

MTL offensives to the west

In 1943, Matroilan launched a series of offensives against Orinese colonies, taking advantage of Orioni's weakened state. Matroilan's surprise attacks caught Orioni off guard, and the empire was slow to respond. Meanwhile, Orioni was secretly providing military assistance to Andalla and Giokto through a long westward circumnavigation through the Manamana Canal. This aid was crucial to Andalla and Giokto's survival, as it allowed them to regroup and prepare for a counterattack. This created a second tipping point.

The tide of the war turned in the first half of 1944 when Orioni's forces, having completed their long journey, launched a surprise counterattack against Matroilan's western occupied areas. This attack, coupled with the growing resistance of Andalla and Giokto, marked the beginning of Matroilan's decline. MTL's western offensives had a significant impact on the course of the Thalassan War. They demonstrated Matroilan's military prowess, but they also alerted Orioni to the threat Matroilan posed. Orioni's subsequent counterattack forced Matroilan to divert its forces to the west, weakening its position in the Tiauhai Sea region. The western offensives also highlighted the importance of regional cooperation in maintaining peace and stability. By taking advantage of Orioni's weakness, Matroilan had provoked a strong response from the sleeping giant. This incident served as a reminder that unchecked aggression could have serious consequences, and that regional alliances were essential for deterring future conflicts.

MTL offensives to the east

In the second half of 1944, Matroilan's expansionist ambitions reached the east, where it threatened to block Manamana Bay, a strategic waterway under the protection of Iverica. This direct threat to Manamana's security brought Iverica into the war, marking a significant escalation in the conflict and a third tipping point. The involvement of Iverica, a major regional power, significantly altered the balance of power in the Thalassan War. Matroilan's offensives, which had been focused on the west, now had to contend with a new front in the east. Additionally, Matroilan's eastward expansion was driven by the presence of an ancient Orinese diaspora in the West-Aurelian region. This diaspora, which had been established centuries earlier, had maintained cultural and linguistic ties with Orioni.

The entry of Iverica into the war triggered an arms race between the three major powers: Matroilan, Orioni, and Iverica. Each nation sought to strengthen its military capabilities, resulting in a rapid increase in the number and sophistication of weapons deployed in the war. The arms race was accompanied by a series of Pyrrhic victories, in which the warring nations achieved short-term gains at the cost of severe losses. These costly battles further drained the resources of the combatants and prolonged the war.

• The Battle of the Southern Straits took place in June 1944, and it involved a naval clash between Matroilan and Orioni fleets. The battle was a tactical victory for Matroilan, as it managed to sink several Orioni warships and to seize control of the Southern Straits. However, the battle was also a costly victory for Matroilan, as it lost its flagship and over 3,000 sailors.
• The Battle of the West Coast took place in July 1945, and it involved a ground offensive by Matroilan forces against Iverica's western territories. The battle was a costly victory for Iverica, as it lost over 10,000 troops and had to retreat from several strategic positions. However, the battle also prevented Iverica from repelling Matroilan's offensive, and it allowed Matroilan to consolidate its control of the Tiauhai Sea region.
• The Siege of Manamana took place in August 1945, and it involved Matroilan forces attempting to capture the key port of Manamana, which was under Iverican control. The siege was a stalemate for several months, and both sides suffered heavy casualties. In the end, Iverica managed to repel the Matroilan offensive, but at a great cost.

MTL's eastward offensives, and the subsequent entry of Iverica into the war, marked a significant turning point in the Thalassan War. Matroilan's expansionist ambitions had been thwarted, and the conflict became a three-way struggle for regional dominance. The entry of Iverica also highlighted the importance of regional alliances in maintaining peace and stability. By bringing a new major power into the war, Matroilan's aggression had inadvertently strengthened the forces opposing it. The Thalassan War continued for several more years, but Matroilan's eastern offensives and the entry of Iverica were decisive moments that ultimately led to its defeat.

Allied offensive

The final 18 months of the Thalassan War saw a decisive shift in the balance of power as the Allied forces, led by Orioni, Andalla, and Iverica, launched a series of coordinated offensives that effectively halted Matroilan's expansionist ambitions. The war had entered a stalemate, and Matroilan's internal divisions, overstretched by the strain of war and the introduction of new technologies, began to undermine its military capabilities.

The Allied forces, particularly Orioni and Iverica, invested heavily in developing new technologies to gain a strategic advantage. Orioni focused on developing advanced rocketry, while Andalla concentrated on improving its airpower. Iverica, with its nuclear expertise, sought to co-develop nuclear weapons with Orioni. In 1946, all three nations had successfully developed rockets, and by the end of 1946, Iverica and Orioni had jointly developed nuclear weapons. The introduction of these new technologies further escalated the conflict and intensified the pressures on Matroilan.

In January 1947, Orinese troops landed on Burkini, a strategically important island in the Oriental Ocean, to reinforce its defenses and prepare for a possible Matroilan offensive. Orinese troops of the 6th, 10th, 101st and 102nd Infantry Division of the Imperial Orinese Army and 10th Marine Regiment of the Imperial Orinese Navy fought against the Matroilan forces during the Battle of Cronulla at the end of the Thalassan War. The Orinese lost 17 men, while about 250 Matroilan were killed. The Battle of Cronulla was a decisive victory for the Orinese forces, who repelled a Matroilan counterattack.

In an attempt to finish the war, the allies launched a nuclear attack on Matroilan, targeting a major city, and causing widespread devastation and loss of life. This attack, however, backfired, as it only served to further mobilize the Allied forces and galvanize international support for a decisive end to the war. The nuclear attack on Matroilan marked a turning point in the war, and the Allied forces pressed their advantage. Matroilan, weakened and isolated, was forced to the negotiating table in February 1947. After negotiations, a peace treaty was signed, formally ending the Thalassan War. The treaty imposed strict limitations on Matroilan's military capabilities and territory, and it established an international peacekeeping force to oversee the region.

Aftermath

  • For Andalla, the Thalassan War had profound implications, both domestically and internationally. The war tested the resilience and resourcefulness of the Commonwealth, shaping its national character and leaving an indelible impact on its collective memory.
• Giokto. The Giokton military was forced to surrender in 1947, granting Andalla the control over Giokto. Throughout the 1950s, the new government began extensive projects to rebuild and modernize the island, and by the 1970s, Giokto became an important financial centre. Today, Giokto is highly-developed; it is evident in the bustling skyscrapers of Giokto's cities.
• Iverica
  • Regional hegemon on the rise.
  • Iverica krijgt de nukes (~neergestort vliegtuig)
• Orioni
  • Reduced from superpower to regional power. Captures SSI rocket tech. Develops space programm.
  • Orioni krijgt de raketten (~onontplofte exemplaren)
• Selayar. In Selayar the outcome of the conflict indirectly led to the outbreak of the Selayari Civil War (1959-1974).
• Sunset Sea Islands. The Empire of Mat Troi Lan came to an end, and was replaced by the Kingdom of Sunset Sea Islands. After a series of crushing military failures, Matroilan was forced to surrender on 9 February 1947. The victorious parties sentenced Gabrielos to a life in exile. He died five years later in a small lookout on an island off the eastern coast of Sunset Island. His youngest son, King Tomasso, was inserted on the throne and the nation, as his older brother, Prince Zenos, had died during the war. The nation was reformed as an independent, constitutional monarchy, the Kingdom of the Sunset Sea Islands was born. Several government officials were replaced with international governors to ensure the SSI would turn into a modern society.
