July 1st, 863 years after the second Nightmare Moon event and the re-assumption of Princess Luna to the dual throne. The Armies of the New Lunar Republic and the Solar Empire have been fighting for the past two years, locked in conflict since the succession of several southern provinces of Equestria, which then formed the New Lunar Republic, with the disposed Princess Luna as its chief of state. Celestia then declared war on the rebellious provinces, in order to bring them back into the Empire.
Several invasion attempts all failed at the hooves of the skillful Republican commander, Big Macintosh, who, after defeating the several invasion attempts, grew bold and began his second invasion of the Solar Empire, with the aim of bringing the horrors of the war, which so far had been fought only on Republican soil, to the citizens of the Empire.
He descended on the town of Fillysburg, which had a store of much need shoes for his troop. This is the story of the battle that ensued. The Battle of Fillysburg.
