Battles over the history of TFEOD...

The Human Colonial Alliance against the Volunteer Corps of the Colonies
The Battle of Kiela, a battle which entered the legend, was the first battle of the First Secession War, in which the newly built Valkyrie Class Battlecarriers of the Freikorps attacked a force of the Human Colonial Alliance by surprise, completely destroying it. In military terms, the battle showed the advantage the battlecarriers possessed, which would set the tone for the military development of centuries to come, and proved that the old converted ships of the HCA weren't as powerful as the galaxy believed. The battle had a huge impact, as it was the direct catalyst which convinced the first million Colonies to sign and ratify the Articles of Colonization, proving that the Colonies can stand up to Earth. As such, the Battle of Kiela is considered to be the bloody beginning of the Federated Colonies.

The United Republics of Earth against the Federated Colonies
The United Republics of Earth broke the Eternal Armistice that had been signed between them and the Federated Colonies at the end of the First Secession War. Taking advantage of a backdoor in the Colonial Defense Network, the forces of Earth attacked the capital system of the Federation, Sol Nova, right in the middle of the Colonial celebrations of the Armistice Day, shutting down most Colonial defenses and destroying the main Colonial forces. After that, the forces of Earth broke all known galactic and intergalactic war regulations and treaties by using extensive nuclear weaponry against the civilian population of the system, especially against the capital planet, Terra Nova, killing hundreds of billions in what came to be known as the Massacre of Terra Nova. A decesive Terran victory, it marked the winning of the first part of the Second Secession War by the United Republics of Earth.

The United Republics of Earth against the Federated Colonies
After the Massacre of Sol Nova and the loss of their capital system, the Federated Colonies gathered under the command of their Hegemon in the system of Xalion, where the remains of the Kriegsflotte put up a desperate resistance against the Terran forces. The failure of the forces of Earth to capture the planet of Xalion due to the incredible resistance of the Freikorps on the surface of the planet led to a desperate counterattack made by the Colonial War Fleet with their flagship, the C.M.S. Terra Nova, which led to the final defeat of all Terran forces in the system, and ended the momentum and advantage the United Republics of Earth had gained after taking their old rivals by surprise. The heroic victory of the Colonials started their return, and became one of the greatest moments of their history. The end of the battle marked the beginning of the Operation Forward Until Dawn, which brought the Federation on the same stand as the United Republics, and eventually led to the end of the war.

The Dothvalian Confederacy against the Delieggen Ascendancy
This was the final, most difficult battle of the Great Delieggen War. Led by High Admiral George Hamilton, the Confederate Navy besieged the Delieggen homeworld of Karlaazen. They duelled the Delieggen armada there, but the real battle took place on the planet below, where thousands of Naval Commandos gave their lives to establish beach heads on the planet.

Eventually however, the Delieggen ran out of defenders in the face of relentless Confederate onslaught. And after razing the cities on the surface, the Confederate soldiers followed their shape-shifting enemies into the tunnels below the planet. What they found there was the fuel of nightmares for centuries to come. Entire cities, all dedicated to some form of darkness. Some form of evil. There were dark shrines, rituals, and clergy. All were slain or destroyed. The Battle of Karlaazen was the last step of an attempted complete xenocide of the Delieggen, and the commandos were thorough in their work. Some, however, survived, and went on to rebuild the Ascendancy. They built in silence, but still they lurked in the shadows.

The Drathian Natives and the Federated Colonies against the Keltaken Empire
The Battle of Drathia initially began as a series of unconnected battles in the system of Drathia. One of the most chaotic and well known battles of the last decade, the battle began with the arrival of the Colonial and Keltaken forces in the system. Although they were officially allied, the tensions between the Keltaken Empire and the Federated Colonies had been raising, which often led to fleets from both nations following the other in unknown systems. The Colonial forces were however suddenly attacked by a third force, and the Keltakens refused to help, instead focusing on the only inhabited planet in the system, Drathia, which was inhabited by a tribal alien race. In accordance with the treaties signed between the Federation and the Empire, such races were to be protected from the usual genocidal actions of the Keltakens, but the forces of the Empire broke it on purpose, landing on the planet, and trying to take away its inhabitants for research, killing any native that opposed it, even using orbital bombardments when the Dratians managed to hold their ground. In the meantime, after managing to defeat their enemy, the Colonials realized what was happening and demanded the Keltakens to stop. In the chaos that followed, the Kriegsflotte and the fleets of the Keltakens entered combat, with the Colonials holding their ground against a numerically superior force, and sending transports to the planet to save as many natives as possible, before retreating. Tactically, the battle was a Colonial victory, as the Colonial War Fleet of the Andromeda has accomplished its tactical objectives, which included saving as many natives as possible, keeping the Keltaken forces away from the planet, and destroying as many enemy ships as possible. But strategically, it was a crushing defeat, as it started the First Intergalactic War, and it allowed the Keltakens to take advantage of the weakness of the Colonial forces in the Andromeda before they started an invasion of the Milky Way, which eventually ended with the defeat of the Colonials and an armistice. In the Colonial history records, this battle is often considered to have been the worst mistake of the Colonies in the entirety of their history, and it marked a huge blow to the Colonials, their ideals, and the way they spread it.

Battle of Goblonius
- Goblonius is attacked by a Keltaken expeditionary force, barely managing to fight off the attackers until Drathian forces arrive and push back the Keltakens. Results in a Goblonian protectorate under the Drathian Fylkirate.

Reclamation of Aiur
- The Eldari return from their exile to reclaim their homeworld, only to find ancient Keltaken constructs dormant beneath the surface. It is also here the Monoliths wreak havoc in various galaxies.

The Intergalactic Armada against the Swarms of the Abyss
Ships of the Intergalactic Armada jump near the desolate planet of Tau Volantis, but the Invaders ambush them. In the process, something was found that might defeat the Invaders, but many nations lose many of their most prized ships.

The Fleets of the Commonwealth against the Swarms of the Abyss
Commonwealth battlefleets arrive in Line Gloria, but is consequently ambushed by Abyssal swarms. The Commonwealth forces inflict horrid losses against the Abyssals, but in the end they are destroyed. It is estimated that around 20,000 Commonwealth warships faced a force that at least 100 times their number, but possibly more. Using shield barriers, nuclear weapons, and unbreakable resolve, the two battlefleets hold on for 8 hours before driving themselves inside the Abyssal swarm and self destructing, obliterating them completely.

Acruani-Confederate Forces Versus the Thirteenth Order Of the Abyss
Acruani ships arrive in the Milky Way. Despite fierce resistance in orbit, Acruani transports carrying the soldiers of Nightmare Company landed on the planet Pegida. This was a small, elite unit, armed with experimental armour improved by the Acruani. It was led by Tau Volantis and HCS Pluto survivor Scott Carver, as well as Archene d'Night of the Acruani Collective. After liberating a POW camp, they are taken to the Marker for the system, where they battle Sigma and two other Abyssal children. Carver is seriously wounded, but survives, along with a good portion of the commandos. Archene also survives, and the battle ends when Sigma's forces are ordered to withdraw.

The Intergalactic Armada against the Swarms of the Abyss
Ships of various nations of the Intergalactic Armada arrive in the ruined system of Sol Nova in an attempt to find the last relic piece of Heaven's Fall. The Invaders are waiting for them. A horrid battle follows. (ongoing)

Battle of Svartsvol
Keltaken ships invade the Drathian rebel capital of Svartsvol. Unable to make a landing due to rebel moon bases, Keltaken General Karraka destroys the planet, and a defeated rebel fleet barely manages to escape.

Battle of Norga
Drathian loyalists attack the rebel stronghold of Norga, securing the planet after bloody fighting both in space, and on the ground. The battle results in the death of Fylkja Zlasa 'God-Seer' and the capture of rebel General Serratus "Shred-Freak" 'Thrill-Kill'.

Siege of Endion(2300)
Endion is an Eldari moon orbiting a gas giant whose sole purpose is to be a research facility. Around 100,000 Eldari scientists, also called "phase smiths", reside there, along with 10 Templar Orders. In 2300, Endion was besieged by the gaseous Kalathi race. These gaseous entities possessed powerful psychic powers much like the Eldari, and they jammed communication between Endion and the rest of the universe, so the phase smiths and Templar Order would have to hold on until the Great Fleet notices that something is wrong and comes to investigate. The Kalathi wished to prevent that, and tried to destroy Endion's orbital defences before that happens, but Endion's warfleet prevented them from success. A string of unsuccessful assaults followed, but the Templar forces were being slowly whittled down in number. After a 5 week long siege, the Phase Smiths reactivate the ancient Strathirite Constructs, which then wiped out the Kalathi in a matter of hours. The Strathirites are then hastily deactivated soon after to prevent them from rampage.

Massacre of Sevastapol Novaratus(3100)
This is one of the more notorious wars fought by the Commonwealth. Here, the Commonwealth finds the homeworld of one of their hated and longtime foes, the Ujarn; crustacean pirates that have terrorized the supply lines of the quadrants of Murmansk and Moscovia for too long. After years of relentless searching, they find the homeworld of the pirates - Sevastapol Novaratus. Shortly thereafter, hundreds of Commonwealth warfleets attack from various directions, unleashing a powerful orbital bombardment using the solar cannons of their Tiger Class Battlecarriers, resulting in life in Sevastapol Novaratus being completely wiped out. The planet's existence, and even the fact that the massacre even took place, has been shrouded in confidentiality, with all but the highest military and political officials of the Commonwealth ever allowed to know of it.

Battle of Nordr Kas(3169)
The frozen planet of Nordr Kas holds something very important for the Eldari survivors after the Aiur System was conquered by the Keltakens - the ancient arkship, the Shield of Aiur, as well thousands of ancient warships and war machines that were left there because the Conclave thought them too dangerous because of the sheer amount of death and suffering they caused. The Eldari aboard the Spear of Adun along with thousands upon thousands of starships landed upon Nordr Kas, only to find that one of their ancient foes, the Kalsari, have turned the desolate planet to a fortress. Determined to take their ancient weapons back, the Eldari sent the Kalsari to hell with relentless orbital attacks and merciless hit and run strikes. After 7 full months, the Kalsari gave up and evacuated Nordr Kas. The Eldari then excavated their weapons of war, which will proved very useful to them later.

The Purge of the Nal'thar(5000 BC)
This is one of the bloodiest campaigns waged by the Union of the Suprion Empires, one which is against their own kind. The Nal'thar, known better as the "Heretics", are believed to be dark shapeshifters, plotted against the government, and practiced heinous debaucheries. For the most part, it was true. Due to constant pressure from the Orders of War, the Council of Seers, as well as the general population, the Thal'hus organize a ruthless Inquisition to hunt down and slaughter the heretics one by one. It resulted in a bloody purge, and the number of Nal'thar killed is believed to be at around 30 billion, out of a total population of 34 billion. Those who survived used interdimensional portals to escape, and to this day, none except for their allies know of their existence. To this day, they plot their vengeance, hiding behind the curtain of galactic events and politics to manipulate events to their own ends and dark purposes.
