The Battle of Earth

The Battle of Earth was one of the final engagements in the Second Great War. It was the last stand of the Alliance. This is the closest the Alliance has ever come to complete destruction.

Alliance Forces
The Alliance was desperate at this point, hoping for a miracle. Earth was all that was left. Even the cities and colonies on the moon (Luna) had been destroyed, along with most of the vast array of ODPs (Orbital Defense Platforms), hangar stations, and battlestations that had once defended Earth, along with almost every orbiting civilian structure. The forces of the Alliance in this battle consisted of a total of 164 ships, including 1 superdreadnought, the Heroic (which was the flagship of the fleet at that point in time), 3 heavy cruisers, 21 destroyers, 37 frigates, and 102 light and medium corvettes, along with about 23 ground-to-orbit cannons from bases on the planet's surface.

Dark Vanguard Forces
The Dark Vanguard were overconfident at this point, assuming that they would win easily. They brought every ship they had in their fleet to totally crush the Alliance forces. They deployed 370 thousand dreadnoughts, 2 million battleships, 7 million heavy cruisers, 27 million combined light and medium cruisers, 135 million destroyers, 238 million frigates, and 997 million corvettes.

Space
The battle began 3 days after the Vanguard took Luna, when missiles were launched from beyond the moon, hitting civilian orbital installations, destroying 22 and damaging 13 more. This was followed by 5 additional waves of missiles, each wave aimed at civilian targets. After the last wave, the Vanguard armada emerged from behind the moon and immediately moved to attack, losing dozens of ships before they got into range. The Alliance forces retreated behind the few remaining orbital defenses, which were swiftly overwhelmed by enemy attacks. By now the fire of remaining defenders had reduced the Vanguard numbers by 7-8 thousand ships, but those losses were nothing to the enemy armada's size. After 4 hours of fighting, the only defender remaining was the Heroic. Even the ground-based weapons had been destroyed by a mix of orbital strikes and ground assaults. However, before the Heroic could be destroyed, the enemy leadership was killed at Darkbase 1, leading to the surrender of the Dark Vanguard and the end of the war.

Land
Two hours into the attack against Earth, the Dark Vanguard had been able to successfully break a hole through the defenders in orbit to begin landing ground forces.

Aftermath
After the surrender, the Vanguard surrendered their entire fleet to the Alliance. After being used to retake the galaxy, these ships were deconstructed for material to rebuild the Alliance navy. After the treaty, there was peace until the Ascendant Saber Crisis.
