Plot
The 2010s: Alien scientists from an alliance of races known as the Galactic Hegemony review footage of the Battle of Agincourt, taken by a survey ship during the Hundred Years' War. They liken humans to the carnivorous, vulpine Shongairi, a species recently admitted to the Hegemony. Ultimately, a Shongairi fleet is sent to establish control of Earth in the name of the Hegemony. Upon arrival in the Solar System, the Shongairi are amazed to discover that in six centuries since the Agincourt survey, the technology base of Earth has advanced considerably, to the Hegemony's classification of "Level II."
The Hegemony constitution prohibits conquest of any Level II or higher society. Fleet Commander Thikair, head of the Shongairi expedition, resolves to ignore this law in service of Shongairi plans to advance beyond their Hegemony rivals and ultimately conquer the galaxy; a human client state could provide scientists and soldiers to this end. Furthermore, the Hegemony's leaders have quietly authorized the Shongairi to attack the "bloodthirsty" humans. Hegemony leaders, mostly pacifist herbivores, view humans as dangerous and morally beyond redemption; they are to be subjugated, or if necessary, exterminated.
The Shongairi kill more than half of Earth's population with orbital strikes, falsely assuming the survivors will surrender. As the Hegemony has to date prohibited war on advanced societies, the Shongairi are completely unprepared for the conflict that ensues. U.S. Air Force remnants using stealth F-22 Raptor aircraft shoot down a flight of Shongairi transport shuttles. U.S. and Russian tanks prove far superior against poorly armored and armed Shongairi vehicles. The Shongairi use further kinetic strikes to destroy the attackers and the remaining human cities as a reprisal, but the survivors continue the struggle as loosely organized guerillas. Superior infantry tactics and weapons cause irreplaceable Shongairi casualties to mount.
