"Dubreton's launched an attack on the new trench!" An out-of-breath runner said as he stumbled into the officers' mess. Without being told, all of the aviators immediately began throwing on their bottle-green jackets to go to battle. Achilles and his crew was the first dragon off the ground, followed closely by Iskierka.

"Assassins, prepare to air assassinate!" Kenway shouted, and a few of the others took positions outside of Achilles's rigging to leap onto the French carrying off the Allies' equipment. "Achilles, two points off starboard bow!"

Achilles nodded as he roared a defiant challenge at a passing French Chanson-de-Guerre. Without stopping, Achilles collided into the heavyweight, allowing his crew to open fire with their rifles and pistols. By the time they had finished, the Chanson-de-Guerre was barely able to make a retreat, and the Assassins turned their attentions to aiding their brethren fighting on the ground.

"William, Kulingile is outnumbered!" Achilles cried out, and Kenway saw that Kulingile was being harried by a number of light- and middleweight dragons. Letting out a blood-chilling roar, Achilles charged in, and Assassins leapt onto the backs of the enemy to kill their crews. Achilles was a terrifying sight to behold as he snapped the neck of an extremely unfortunate lightweight with his powerful jaws, and his captain was equally merciless as he drove the edge of his tomahawk into the brain matter of a Spanish aviator.

"Signals coming in from Lily, Kenway!" An Assassin armed with a spyglass reported, and Kenway nodded as he saw the flags flying from beneath the Longwing's wings.

"Captain Harcourt's calling for a withdrawal. Achilles, pray wear to leeward and follow her."

"They've struck again!" Another runner said, and Kenway was sorely tempted to slam his head into the table. Here he was, ready to enjoy his well-earned banana, and now the French had interrupted his snack time. How typical of them.

Rain was falling in sheets as Lily's formation flew above the battlefield, and it flooded the siege trenches the Allied engineers were digging. The French were swarming out of the fortress, chasing after the broken British, Spanish, and Portuguese as they ran away.

"All hands, prepare to drop!" Kenway shouted through his speaking trumpet. Within a minute, the Assassins were hanging from Achilles's belly rigging, and they begun a rapid descent down some ropes to the ground. Unclipping their carabiners just in time for their feet to hit the ground, the ropes were then hauled back up to Achilles's belly as the Assassins on the ground drew their weapons of choice.

"Into them, go!" Kenway shouted, and the Assassins began taking down the charging French with ruthless efficiency. Gunpowder weapons would be near-useless in the wet weather, so the Assassins were reduced to swords and bayonets as Achilles soared overhead.

Parrying the bayonet of a young French soldier barely into his twenties, Kenway kicked him away, and unsheathing his Hidden Blade, he spung around just in time to intercept another French soldier's bayonet, and he thrust the blade into his throat, killing him.

Another French soldier screamed with rage as he charged towards Kenway, who simply deflected his bayonet off to the side with his tomahawk, and he tripped the soldier by extending a foot out. Slipping a throwing knife out of his pouch, he hurled at a distracted Frenchman's back, and he crumpled forward onto the muddy ground.

"Hold them back!" Kenway shouted hoarsely, thunder booming overhead as the rain struck him like bullets. Pulling a Frenchman closer with the help of a rope dart, Kenway skewered him with a scavenged sword and withdrew it, leaving the blade stained with crimson blood that was quickly washed away by the rain. Picking up the fallen soldier's musket, Kenway hurled it like a spear towards an unsuspecting Spaniard, who suddenly found himself skewered from behind.

The Assassin the Spaniard had been fighting nodded his thanks towards Kenway, and she turned to face another foe. Kenway then heard movement behind him, and he turned to see French and Spanish soldiers approaching him, bayonets at the ready.

Flying above Kenway was not his dragon Achilles, but a force of nature howling for dragon blood. The scaled tempest could not be stopped - would not be stopped, and It was ruthless as it attacked enemy dragons no matter their size.

That was the real power of the American Sky Hunters. They were bred to be much like what the American Founding Fathers hoped the young United States would be - favoring calm peace, yet when pushed, a deadly force to be reckoned with. Even without a projectile weapon like Lily's venom, Iskierka's fire, or other dragons' rifles, It was death from afar.

Achilles roared an indiscernible challenge as he tore a poor Flecha-del-Fuego apart with his claws, and he was soon locked in deadly combat with the largest heavyweight amongst the French military presence at Burgos.

—

It was a fight to the finish - not between the Allies and the French, but the Assassins and whoever was unfortunate enough to stand in their way. By the end of the long day, the French had retreated back into the fort, and the exhausted Assassins and their dragon had to be helped back to the fort.

"Did… we win?" Kenway asked his dragon softly as they lied down together, and Achilles nodded. "We drove them back, dear William. Now pray rest, so that we may face tomorrow with all of our strength."
