Second Great War

The Great War, also sometimes called the Twenty-Six Years' War, was a global war that lasted from 1927 to 1953. The vast majority of the world's countries—including all of the Great Powers of the time - were involved. A state of total war emerged, directly involving more than 100 million people and resulting in over 64 million deaths. The major participants threw their entire economic, industrial, and scientific capabilities behind the war effort, blurring the distinction between civilian and military resources. It is marked by massive strategic bombing campaigns of industrial and civilian centers, trench warfare, the rise of mechanized warfare, and the only use of nuclear arms in war. It remains the deadliest conflict in human history.

Background
Starting with the First Fratricide and Third Caroline War, the Holy Levantine Empire entered a period of terminal decline in terms of influence over its members and the working of its core institutions. Despite the best efforts of the Imperial Court in Corcra, members of the Empire were rapidly liberalizing and eschewing centralized power in favor of various levels of devolution outside of the Imperial power structure. This started with the Fiannriai White Revolution in 1823 when the Kingdom of Culfra was effectively dissolved and the Republic of Kuhlfros took its place. In the south, the Recess of the Julii continued as the Apostolic Kingdom of Urcea had acted autonomously of the Empire since the Second Caroline War, dramatically reducing the resources and manpower available to the Empire. The Empire, and especially the Derians, tried to isolate Urcea in turn, and most of the Electors greatly resented the Urcean Crown since the War of the Caroline Succession temporarily stripped them of their authority in the later half of the 18th century. Urcea's conquest of Carolina and defeat of most of the Kingdom of Dericania in the Third Caroline War proved another body blow to the authority of the Empire and created a generation of veterans in Dericania who had been exposed to some of the Crown Liberalism ideas of the Urceans while captive as. As a consequence of the Imperial Court in Corcra, many Derians in the Kingdom of Dericania found themselves chafing under what Imperial authority remained, and particularly, the Derian bourgeois found that their Kingdom was falling behind the rest of the crumbling Empire in terms of liberalization. By the People’s Spring of 1848, formidable groups had formed in 15 states and formed their own protests, revolts, and organized labor actions. These were brutally suppressed by the Emperor, Louis XI.

In the 1880s Diamavya invaded Fiannria and the Emperor enforced a non-engagement order, barring any of the Holy Levantine Empire states from coming to Fiannria’ defense. This breach of the long standing mutual defense custom of the empire led many to hold the court in Corcra in contempt and once again sparked the flames of dissent in the Kingdom of Dericania. As a result of the Third Caroline War, many Derians had long feared that Urcea would attempt to consume the Kingdom of Dericania and its constituent states, and Derians now felt that the only thing keeping the Urceans away - the Imperial Court - would no longer protect them. The breach of the mutual defense custom flamed these fears as some speculated that Corcra would attempt to keep the “northern liberals” out of “southern politics”.

In the 1890s, the Red Interregnum broke out in Urcea, and this destructive civil war lead to the Depression of 1900, which destabilized the Empire and lead to mass uprisings in the Kingdom of Dericania. It also renewed an enmity between Caphiria and Urcea that would be an important undercurrent for the conflict in Catholic Levantia to come. Members of the Empire, and eventually the Empire as a whole, intervened in the war on behalf of House de Weluta against the Crown Regency of Gréagóir FitzRex, which sought, among other things, to have Urcea secede from the Holy Levantine Empire. FitzRex was replaced with the left wing short-lived Urcean Republic, which created an ideal radical socialist state from which Derian revolutionaries were inspired. With the de Welutas restored to the Julian Throne, the Recess of the Julii came to an end, temporarily strengthening the Empire despite the severe economic depression and uprisings. During the conflict, there were isolated shooting incidents between the Levantines and Caphirians, who supported the Crown Regency. These skirmishes would prove to be a prelude to the coming conflict.

In 1909, the Grand Duchy of Anivania was gripped by violence as republican forces took control of the ducal palace and declared a republic. By 1911, they concluded a civil war and formalized the Serene Republic of Anivania. Utilization of “Serene” to emphasize the sovereignty of the state was not recognized by most other Imperial states, but its success in achieving and maintaining autonomy sparked other movements later. In 1920, as it became clear violence and instability was gripping the Empire, the Collegial Electorate did what would have been unthinkable a century before and elected King James VI as Holy Levantine Emperor in a last ditch effort to stabilize the Empire. It was thought that Urcea's muscle behind the Empire may give it the resources needed to hold itself together. The next year, in 1921, the Electorate of Aescarata faced a socialist revolt. Urcea intervened and soon the intervention became an occupation. By 1925, the region was considered a "powder keg", waiting for the right spark to explode. Seeking to capitalize on the internal strife in the Empire and to stem "Levantine Creep", in 1922, Caphiria began to send agents to foment unrest in the Holy Levantine Empire. Caphiria was motivated not only by an enmity for the Empire but by a renewed sense of Derian nationalism, seeking to unify the Latinic world in the orbit of Venceia. Caphiria's interest was not in Dericania per se, but rather eastward, in Veltorina, whose independence was guaranteed by Urcea and other Imperial states.

The 1925 election in the Republic of Lutsana saw the majority of seats in the legislature go to the Lutsana Worker’s Party and the appointment of a communist Prime Minister. Emperor James III and the Imperial Diet suppressed the results and called for a new election with more “acceptable” results, fearing that the excesses of the Worker's Party may lead to another iteration of the Urcean Republic. A movement of seeking more self-determination, that had long been simmering across the Derian States, erupted. The Lutsana Worker’s Party refused to heed the demands of the Diet and the Emperor. The Army of Lutsana’s high command sided with the Emperor and announced they would arrest any member of the Worker’s Party who attempted to enter the parliamentary chambers. The Worker’s Party formed an army of workers and stormed the parliament building, challenging the will of the soldiers to shoot upon their countrymen. The soldiers retreated, and the matter was dropped. In February 1926, a syndicalist government was elected in Geneseo; the Duke of Geneseo validated the election results and then fled for Corcra. Again, the Emperor demanded a recount and sent detachment of the Royal and Imperial Army. They arrived at the border of Urcea and the Margrave of Novaustramark and were fired upon when they refused to stop. The incident sparked a border conflict between Urcea and Novaustramark, in which Urcea insisted that Imperial troops could not be barred from passage in any territory in the Holy Levantine Empire. Several Derian states pushed back declaring that they maintained the right to control their own borders and admit and deny who they chose. In turn, the Emperor began to mobilize the entirety of the Royal and Imperial Army. The mobilization was enough to quell the disquiet for the moment. The Army was stationed along the border of Urcea and the Burgundian territories of Faramount, both to intimidate rogue Deric states but also to emphasize a show of support for the government of Burgundie, which was viewed with increasing antagonism from the other state of Dericania. Additionally, the dissenting states were leveled with the price of the mobilization and billeting as punishment for their recalcitrance. As the price tag grew so too did the discontentment. The Imperial Diet erupted into fist fights almost daily as the smaller states vied to get out from under the new Imperial tax.

In July the Grand Duchy of Loreseia exploded with a rash of violence towards the Imperial tax collectors. 13 of them were killed and 4 more were beaten heavily. The Imperial Bank branches were robbed and set of fire in 3 cities. In the Duchy of Upper Verecundia a mob attacked the Ducal Palace and burned one of its wings to the ground. August saw an escalation of violence across the region. Violent street brawls became common in the streets of major cities as political parties and anti-monarchists attempted to control important sectors and pieces of infrastructure. The Emperor declared his intention to restore order, but acted hesitantly in order to avoid further conflagration in Dericania. By August, the Grand Duke had fled to Urceopolis and a provisional government was established.

Meanwhile, Caphiria hosted a secret meeting of Derian nationalists in order to strategize how to break the Levantine Imperial system. Under Caphirian guidance, the nationalist groups formed two field armies which were to be trained and supplied by Caphirian Imperial Legion attachés. The Loreseian provisional government volunteered as the landing point for the armies and to host the joint headquarters. On March 12, 1927 a massive flotilla of the Caphirian Imperial Naval Fleet landed the newly named Allied Armies of Dericania. The field armies, the Northern and Southern Liberation Legions, set out to southern Loreseia where they would divide and move to their respective theaters to encourage other state armies to join them and stand up against the Imperial Government and seek national sovereignty and autonomy. A minority of the leaders also sought the total dissolution of the Kingdom of Dericania or the entire Holy Levantine Empire.

1927
The Northern Legion which landed in Loresia to start the conflict was numerically superior technologically inferior and relatively untrained compared to the forces they would face. They numbered several hundred thousand infantry soldiers and officers and an impressive amount of cavalrymen, and lacked any consistent form of mechanization and comprised of only a sparse number of artillery pieces, as it was hoped local forces may defect and provide the heavy artillery necessary for a campaign. Their cavalry units were primarily armed with 19th century carbine patterns like the and the. Artillery support was limited to light and medium field guns as most large bore artillery pieces were built into forts and city fortifications and they lacked the logistical train to move and support them. The Northern Legion was supported by a machine gun corps that focused its power around its s to remain mobile with its infantry. The Southern Legion, a relatively small force of approximately 42,000 infantrymen and 8,000 cavalry included 6 squadrons of armored cars and a well-armed artillery element. A system of railways supported them to keep their logistical needs met. The Legion's infantry were provided with a great variety of small arms, requiring a complex logistical effort that slowed the Legion significantly, rendering the railways mostly unusable as the army tried to keep its 14 or more different calibers supplied. Machine guns from the Army of Anivania and the Balloon Corps from the Army Air Service of Cannella were provided to the Southern Legion.

Upon hearing of the landing the Royal and Imperial Army demanded that all parties lay down their arms, and the Emperor made a direct appeal to the states of Dericania to muster their armies and gendarmes to quell any dissent and halt the invasion. A few weeks of awkward mobilizations and posturing started to see battle lines being drawn across Dericania. On March 29th, the Allied Armies of Dericania declared war on the Holy Levantine Empire and the Northern Legion marched on Drusla. '''The Duchy of Drusla, a strong ally in the region of Burgundie, called upon the Empire for aid. Upon consultation with the Emperor, the Army of Burgundie was set to deploy a division of freshly recruited militia to Drusla, but a telegram from the Government of Fiannria informed Burgundie that their forces entering the other states of Dericania would be considered a violation of Imperial law and the neutrality of Dericania, which Kuhlfros could not accept. The abstention of Fiannria from formally joining the Imperial Army and its threat was viewed as another fatal blow to Imperial stability and viewed as a tacit support for the nationalist movement in Dericania. Imperial diplomats were sent to Brídhaven to negotiate a deal and the Burgoignesc troops were stationed on the border of Burgundie as negotiations pressed onward. (This doesn't make sense anymore in light of the Derian-Burgundian element).''' The Northern Legion arrived at the capital of Drusla, however, before the Burgoignesc forces could cross the border. The city fell without a fight and the Army of Drusla was disbanded. The Free State of Drusla joined Loreseia as the first two self-declared independent countries in Dericania.

1928
In 1928, campaigning throughout Dericania continued without clear result, though many of the remaining principalities of Dericania were overthrown by socialists, liberals, and nationalists groups, who sometimes worked in tandem and in some states opposed each other. A civil war erupted between militant nationalists and liberals in the former Electorate of Aedanica and Caphirian diplomats had to step in to prevent the entire project from collapsing as a consequence. It was in this context that the Urcean government intercepted and decoded telegraph instructions from Venceia for the diplomats. The so-called "Order Affair" nearly led to direct war between Urcea and Caphiria, but Urceopolis ultimately backed down in an attempt to avoid a two-front war it did not believe itself prepared for. In November of 1928, the various Derian free-states and Legion-occupied principalities bound themselves together into the provisional Deric Republic, putting both legions under its command hierarchy. Despite the vastly different ideologies and political programs of the different states of Dericania, the Republic managed to remain unified for a period of time with the focus on the war effort.

1929
In 1929, the Emperor died, and his son, Brian, was elected Emperor of the Levantines as Emperor Brian VIII. Many members of the Collegial Electorate, some of whom were now in exile, perceived that the Urcean Crown was acting with some hesitation, leading to disagreement among its members as to whether or not to continue the so-called "Urcean Experiment". In the final meeting of the Collegial Electorate however, King Brian IV received a plurality of twelve votes among five different candidates chosen by the thirty electors. The new Emperor had to forego the ceremonial coronation due to the emergency gripping the Empire and opted for the Pope to crown him in a small ceremony in St. Peter's Archbasilica. Earlier that year, Fhainnaeran, looking to reverse its losses from the Fourth Kin War in the 1880s, invaded northwestern Fiannria. Diplomatic correspondence between Urceopolis and Brídhaven proved Caphirian involvement and support behind the Fhainns' decision to invade. As a consequence, Fiannria stopped its diplomatic and alleged materiel support of the Derian nationalists in order to focus on defending itself from a potential Fhainnin incursion, and formed a national emergency.

Matavista Campaign
Hoping to capitalize on the withdrawal of the Fiannriai support, the Burgoignesc III Army Corps advanced to the foot of the Matavistas Mountains, in the Republic of Lutsana. The Burgoignians threw themselves against the lower slopes with enthusiasm. After quick gains in the foothills, the soldiers faced the steep rises and formidable terrain of the mountains. This gave the advantage to the Lutsanan and Jasonian Alpini. The Burgoignesc called upon their own alpine troops to dislodge the defenders. The 3rd Beaumiota Alpine and 8th Ouitelier Specialist Engineer Battalions were brought but the trenchworks and well-placed artillery saw them defeated within a month. The Army Air Service attempted bombing raids on the lower artillery emplacements but were thwarted by anti-aircraft batteries on higher peaks. The Raulie Bushrangers were called to the front and put to action. Their aggressive training on Mount Vitroluire in Burdeboch prepared them well for the harsh environment of the Matavistas Mountains. Arriving in October of 1929, the Bushrangers had taken the fight to the Lutsanans and Jasonians by mid-December. The front bodged down as winter set in. The Raulie Bushrangers were supported by the entire Beaumiota, Courmont, and Martiseau Alpine Regiments. As the early thaw of 1930, crept into the mountain ridges, the action resumed. Sappers readily dug and blasted deeper into the rock. Cannonades were constant. The highest elevations of the Matavistas were forever altered as summits were blasted, crevices and valleys were filled in with intentional landslides. The majority of the Burgoignesc III Army Corps moved on to other but the various Alpine units of the Army of Burgundie and its Burgoignesc Foreign Legion cycled through the Matavistas through the end of the war.

1930
Up through 1930, the conflict took the form of the last semi-Maurician, as soldiers fought in loose formation and cavalry charges were expected to be battle-ending blows, but it was clear from 1928 onward that these tactics were growing more ineffective with each battle, especially as Urcean industry began to roar to life as Emperor Brian recognized this conflict as the beginning of based on many of the lessons learned during the Red Interregnum. By 1930, the Caphirian government began an effort to ship more machine guns to Levantia in order to prevent the two Legions from losing parity on the battlefield with the better equipped Royal and Imperial Army. By August of 1930, had set in as the two Legions formed a very long defensive line surrounding the core region of the Deric Republic, including Corcra. The rest of the year would see both sides struggle to advance, though Urcea began to deploy prototype mechanized and armored units by the Fall of 1931, breaking the line in some places and allowing for a slow advance, though the unreliability of these new units would mean Urcea's advance would remain slow. While tactics were still adjusting to the technological realities of the 1930s, the Royal and Imperial Army's artillery core gained valuable experience with most units coming out of the Second Fratricide as veterans; consequently, the power of artillery began to shift the fighting in favor of the Royal and Imperial Army in the situations where its new technologies had not.

With the Royal and Imperial Army on the advance, secret meetings began to take place in Urceopolis between delegates of some of the rebelling states and the Imperial government. The rift between the Caphirian-supported nationalists and the liberals, as well as the socialist states, had grown significantly in the three years since the Order Affair, and many of the liberal Derians were interested in peace, chief among them being the provisional government of Corcra. The Derian delegates argued that their goals and the Urcean ideology of Crown Liberalism were not incompatible and that the liberals had no desire to find themselves under Caphirian suzerainty. Negotiations continued in secret through most of the 1932 campaign season, as Caphiria finally felt confident enough in the turmoil in Levantia to declare war on Veltorina. The spread of hostilities to Sarpedon gave Urcea an extra incentive to end the fighting, and the fears of the Collegial Electors from 1929 were realized when Emperor Brian, seeing a possible end to the war, agreed to terms with the liberal states to recognize their reorganization. Emperor Brian also agreed to discuss a later settlement on the final state of the Empire and Kingdom of Dericania, and agreed to peace - these terms were echoed in the Treaty of Corcra. Dozens of disaffected princes in exile in Urceopolis began to riot and were promptly arrested. The final phase of the war, following the so-called Liberal Shift, would see fighting between Derians as many of the liberal states joined the Royal and Imperial Army against both radical nationalists and socialist republicans in Dericania.

By 1935, the Northern and Southern Legions were confined to a territory roughly equaling the Grand Duchy of Loresia and spent much of the time campaigning against socialist insurgents in Loresia and from other Derian states rather than Imperial forces. With the end of the Levantine front in sight, the Apostolic Kingdom of Urcea declared war on the Imperium of Caphiria on February 3rd and began to actively interdict Caphirian supply shipments to Dericania, though Urcea had been actively supplying Veltorina with arms and advisers for about three years. On May 2nd, the Northern and Southern Legions surrendered to the Royal and Imperial Army. Despite his victory, Emperor Brian surveyed Levantia and found a Fiannria undefended by the Empire, a Burgundie hopelessly engaged overseas, and a war-weary Kingdom of Dericania. Fearing an attempted resurgence of Imperial power, Fiannria announced its secession from the Holy Levantine Empire on May 10th. Accepting the inevitable, the Emperor issued a formal proclamation "forever relinquishing...the responsibilities and administration of Imperial Governance in the Kingdoms of Dericania and Culfra", effectively recognizing the collapse and end of the Holy Levantine Empire. Urcea, Kuhlfros, Burgundie, and the states of Dericania agreed to the Treaty of Corcra. In the Treaty, all states acknowledged the "end" of the Empire and the Deric states pledged to end any association with Caphiria, and the treaty recognized the Empire's continued existence only inclusive of Urcea. The Treaty also promised a future permanent settlement with regards to Dericania, though this would not come to fruition until 1953 with the establishment of the Deric States. With a separate peace found in Dericania, the Royal and Imperial Army was sent west to focus the Kingdom's entire efforts against the war with Caphiria while sending arms and materiel to Fiannria. Despite the end of the larger conflict between great powers in Dericania, the Third Fratricide between the new liberal regimes and socialist insurgents would continue into the 1950s, leaving the former Kingdom of Dericania devastated from decades of warfare.

Background
Beginning in the 17th century, Urcea and the Holy Levantine Empire began to directly confront Caphiria and worked proactively to prevent its spread into Levantia. The Levantine powers began intervene in various conflicts and international incidents on Sarpedon, which Venceia had long considered its prerogative. In the Veltorine War of Independence in the 1770s and 1780s, Urcea on behalf of the Holy Levantine Empire intervened, aiding the eastern provinces of Caphiria in their quest to secede. Not only did Caphiria lose that war, infuriatingly losing half of its territory to the new nation of Veltorina, but Urcea gained the new Kingdom of Dorhaven, giving the Levantines a toehold on mainland Sarpedon. Later, the Levantines gained the Legatation of Ankivara and Port de Vent. Out of these developments, the conspiracy theory of Levantine Creep developed - and Caphirian policymakers were determined to make any moves necessary to disrupt and dislodge the Levantine powers, actions it claimed to take in self defense.

The independence of Veltorina was considered a grave affront to the prestige and independence of Caphiria, but with guarantees on its independence from the Holy Levantine Empire, Caphiria was unwilling to take on the Empire by itself. Throughout the 19th century, Caphiria made contact with agitators and rebels throughout the Empire and especially within Dericania. Famously, 1848 revolutionaries in Dericania following the Second Caroline War refused to accept Caphirian assistance, hoping to curry favor with the Emperor of the Levantines, a strategy that failed. Caphirian concerns with Veltorina were escalated dramatically with the Tyrian Revolution in 1864, which turned its eastern neighbor into a socialist state. Despite this development, the Levantines refused to abandon Veltorina. Caphirian policymakers began to develop a long-term plan on how to proceed, and would spend the next several decades waiting for an opening.

A massive opportunity presented itself in the 1890s with the rise of Gréagóir FitzRex in Urcea and beginning of the Red Interregnum. Caphiria offered its full support to FitzRex, providing materiel and volunteers to fight against the now-hated House de Weluta. The prospect of a FitzRex victory was promising not only due to the destabilizing nature of regime change but because his desire to destroy socialism and secede from the Holy Levantine Empire lined up with Caphiria's own goals, and FitzRex indicated that if he was victorious, he may be willing to surrender Dorhaven and would not interfere in Veltorina. The Imperial Naval Fleet began to actively interdict the Navy of Burgundie, which impeded the Legitimist cause significantly. FitzRex began to embrace socialism in order to court lower class revolutionaries, allowing socialists to win a majority in the Concilium Daoni in 1900. Caphiria, bitterly disappointed, continued to support the regime with limited vigor, and their gradual withdrawal led to the Fall of Cana. The collapse of FitzRex's Crown Regency and the rise of the short-lived Urcean Republic led Venceia to reluctantly recognize the restoration of House de Weluta, but it had learned lessons during the war. Its preparations lead to the successful strategy described above in the Levantine theater; the full-blown civil war within the collapsing Holy Levantine Empire finally gave Caphiria the perfect opportunity to strike.

Continental Front
Having sufficiently caused a major conflict in Levantia which would distract Urcea and the Holy Levantine Empire from affairs elsewhere, Caphiria declared war and crossed the border of Veltorina on August 1st, 1932. The forces of Veltorina had long been preparing for such an invasion, which Urceopolis believed to be imminent, and the Imperial Legion spent much of 1932-1934 attempting to break through the heavily fortified borderlands with limited success. Caphiria's declaration of war with Veltorina would also draw in the Kingdom of Pantora which had held an alliance with Velot An attempt to break through in Balatum in the spring of 1935 was successful but saw Veltorine forces temporarily contain the Legions.

In February 1935, Urcea formally declared war on Caphiria although it had been responsible for providing war materiel and advisers since the beginning of hostilities in 1932. Thinking quickly, the Imperial Legion high command determined that it needed to break through the Veltorine defense line immediately, before the arrival of reinforcements from the Royal and Imperial Army or the war could potentially be lost. An extremely high-casualty all-out offensive in modern Sucalagio in July 1935 was waged and by the end of the month the Legions had broken the Veltorine defense lines, although it's estimated a quarter of a million Caphirians were killed in the fighting. The so-called July Offensive also saw the first major use of the Imperial Aerial Defense Force in a revolutionary coordinated land-air operation, informing Caphirian commanders for how to wage aggressive campaigns later in the war. The pioneering use of aircraft in the July Offensive - they had previously been used primarily for reconnaissance and strategic bombing - led all parties in the war to scramble to build s and based on the lessons learned during the offensive.

The static border defenses were immediately demolished, and the Legions spent the remainder of the year attempting to regroup before furthering their advance.

Urlazio and Naval Front
Urcea's Royal Navy, with logistical support from the Navy of Burgundie, began to interdict trade between Urlazio and mainland Caphiria in February 1935, and began launching raids and strikes on key areas in hopes of baiting Caphiria's Imperial Naval Fleet into open combat in the Sea of Urlazio. The Royal and Imperial Army began rapidly reinforcing the Urcean-occupied portions of the island in preparation for a Caphirian assault. No assault came, however, as most of the available reserves had been pooled on the continent for the July Offensive. Despite the lack of an invasion, the Imperial Naval Fleet launched a campaign in March of 1935 intending to destroy the Royal Navy's Sarpedon Squadron, opening up a potential attack on Halfway. The loss of Halfway would cut Urcea's ability to resupply in Veltorina or Dorhaven, leaving them open to invasion by Caphiria. The Imperial Naval Fleet believed it could destroy the Sarpedon Squadron by concentrating most of its forces against it, employing a strategy that would render the Royal Navy useless, allowing the Imperial Naval Fleet to focus on the Navy of Burgundie. On March 19th, 1935, the two sides met at the Battle of the Adonáire Strait after two weeks of probing attacks by the Imperial Naval Fleet. Despite the concentration of forces and superior numbers, it became clear by the afternoon that Caphiria had drastically underestimated the capability and technological sophistication of the Royal Navy, and by five in the afternoon the two forces had fought to a draw, with none of Urcea's ships severely damaged and a small handful of Caphirian cruisers having been lost. One of Urcea's Canaery-class aircraft carriers, which had been in use primarily for reconnaissance purposes, decided to employ its experimental jury-rigged torpedo adaptation on its planes. Launching from HMCMS Aedanicus Carolinicus, twenty torpedo bombers inflicted severe damage on the Imperial Naval Fleet, which heretofore had not equipped its ships with anti-air complements. The twenty jury-rigged planes implemented severe losses on the Imperial Naval Fleet in a few sorties. At the end of the day, four Caphirian battleships, ten battlecruisers, and a handful of light cruisers were severely damaged or sunk. The battle signaled the dawn of naval air power, but also severely weakened the Imperial Naval Fleet and left it functionally a non-factor in the Sea of Canete for the remainder of the war, establishing naval supremacy for Urcea and Burgundie.

Legacy
Despite decades of bloodshed affecting the vast majority of the world's population, the war came to an inconclusive end. Caphiria managed to annex Veltorina but was largely unable to make any headway against Urcea in Urlazio, parts of Veltorina, and Dorhaven and was forced to cede large areas of land to the newly created Valcenian Confederation, including the Konstandina Canal. Urcea could not prevent the collapse of the Holy Levantine Empire, but managed to stabilize the continent and close it to Caphirian influence, paving the way for the establishment of the Levantine Union. While the Royal and Imperial Army could not meaningfully defeat Caphiria in the field, the Caphirians were likewise unable to challenge the naval and air superiority of Urcea and Burgundie. Caphiria also failed to break the diplomatic, economic, and political importance of Urcea and Burgundie in Levantia, which was its primary goal in the late 1920s. The late stage of the war saw both of these powers rapidly escalate the conflict in an effort to establish themselves as the sole superpower, which neither was able to do, leading to the eventual Occidental Cold War. While the failure of arms to establish dominance in the Occident was the primary takeaway in both Venceia and Urceopolis, the decades of what many perceived to be meaningless bloodshed lead to the establishment of the League of Nations in an effort to prevent future conflict.

In addition to the geopolitical ramifications of the conflict, military thinking and technology were entirely revolutionized over the course of the quarter century-long war. Early war fighting in Levantia continued to use 19th-century doctrines of mass assault based on large-scale infantry assaults only employing small arms and, in some circumstances, equine cavalry. The proliferation of machine guns by 1930 changed warfare completely as military tactics officers were trained in proved largely irrelevant. By the end of the Second Fratricide, the trench warfare situation had largely been broken by pioneering use of artillery joined by the new technologies of mechanized transport and armor, lessons that were not lost in Sarpedon as Caphiria began rapid mechanization to prepare for the eventual direct war with Urcea. Many historians have noted that the effect on warfare the Great War had can be easily perceived based on the fact that, before the war, every Great Power relied on horses to move supplies and artillery around. By 1940, each of the great powers was fully mechanized and motorized, revolutionizing logistics in a relatively short 13-year span. The average infantry kit was revolutionized as well. To enter the war, Urcea was employing rifles, such as the SRM-9 and SRM-9C by 1929. By the time hostilities concluded, many LOTA forces - especially those of the Royal and Imperial Army - were using either selective-fire, such as the SARM-1 Model 1945, or advanced, semi-automatic s.

Military developments were not limited to revolutionizing land warfare. The importance of air power became evident during the conflict as all sides scrambled to develop and mobilize a workable air force. The Levantine powers initially focused on strategic bombing via the use of until it became apparent that these were easily countered by nascent fighters and ground-based artillery. On the sea, naval warfare was changed forever following the advent of torpedo bombers at the Battle of the Adonáire Strait gave Urcea a clear advantage, demonstrating the value of s and portending the impending decline of battleships and other surface warfare ships. The use of strategic air power grew exponentially by year, and by the end of the war it allowed Caphiria to detonate the first ever nuclear bomb dropped from an airplane.

Technological developments during the war were not limited to military advancements. The invention of rudimentary military rockets during the war was refined during the late war and 1950s allowing for the creation of various space programs throughout the world. The advent of nuclear fission not only provided the great powers with a weapon of unimaginable destructiveness, but it also provided the ability to tap into nearly unlimited nuclear power for civilian applications. Logistical concerns of shipping supplies to various far-flung combat theaters lead to the rapid advancement of refrigeration technology, and by the end of the war refrigerators were readily available for civilian consumption and were in most homes. The development of the jet for military applications soon lead to very early civilian jetliners entering rotation by the war's end. The race to motorize and mechanize lead to major advancements in automobile technology, making them easier to construct, faster, more reliable, and cheaper for civilian consumers.
