Captain John Granby of the British Aerial Corps was in high spirits, along with the rest of the aviators stationed near Burgos. They had managed to capture another fire-breather for the Corps's use, and it was all thanks to Kenway and his dragon, Achilles. It didn't hurt that all of the captains present at the skirmish received a hefty amount of prize money, either.

Granby strode over to where Achilles was resting and his crew was at work, repairing sections of his harness or cleaning their weapons. "Hello, Achilles - is your captain hereabouts?"

"William is taking a nap - or at least that's what he told me. You're more likely to find him raiding the food stores for those fruits he has an obsession with." Achilles snorted, and Granby blinked as he began walking towards the covert's food stores.

Meanwhile, Kenway was not napping, nor was he conducting a one-man pantry raid as Achilles's cover suggested. He was inside his tent, preparing his equipment to infiltrate Burgos Castle. Stealth would be of utmost importance inside the heavily-guarded castle, so no gunpowder weapons would be brought with him.

He had sharpened his two swords with a whetstone, and he had slung his bow around his chest. Rope darts and throwing knives were kept handy on his belt, and he twirled the tomahawk his father had used during the Revolution before sheathing it. And last, but not least, were the hidden blades mounted on his wrists.

With a flick of the wrist, both blades unsheathed themselves, and Kenway nodded in satisfaction as he pulled up his hood. Leaving his tent, he began walking towards the covert gates.

"I'll be taking a walk around the camp, mates." Kenway said, nodding towards the two midwingmen standing guard with rifles, and without saying another word, he continued walking.

There was a lone tree some distance away from the covert, and it was here that Kenway found the horse left by his contact. It was a swift-looking gray stallion, and he now mounted it to ride off into the sunset towards Burgos Castle, hooves thundering on the pavement.

It was nightfall as he reached the section of the castle walls that been hit by the Anglo-Portuguese cannon fire. Avoiding the French and Spanish patrols on the way there had been easy - their lanterns gave away their positions, and he was able to ride out of their line of sight.

Dismounting his horse, Kenway walked up to the high wall. It had stone bricks missing in some places and an entire hole through the wall in another. Perfect for climbing.

Kenway took a few large steps back to take a running leap atop the wall, and he began surging his way up the wall like a monkey. As he neared the top of the wall, he could hear footsteps, and he pressed himself as close to the wall as possible to avoid being seen by the French sentry.

The sentry paused as he gazed around the countryside from his position behind the battlements, and Kenway breathed a sigh of relief as the sentry went away. Hand and hand went up over the other as Kenway lightly landed onto the top of the wall without a sound.

Before the sentry knew it, he had a hand clamped over his mouth as Kenway drove his hidden blade into his back, and Kenway laid his kill down carefully onto the wall to avoid making a sound. "Quién eres?"

"Me llamo William Kenway." Kenway answered easily as if he didn't just stab a guy, and as he stood up to face the change of watch, he pointed off into the distant countryside. "Qué es esto allá?"

The sentry was caught off-guard by the intruder's introduction, and as he turned to look, William hurled a knife at his head. Unfortunately, it didn't land blade first, and its pommel struck the sentry's skull, fracturing it and knocking the sentry out.

Kenway casually walked over to retrieve his fallen throwing knife. "I can't believe he actually bought that, and the same thing goes for his hat… Aw, well."

Throwing the second sentry over the battlements and stripping the first sentry naked before disposing of the body over the wall, Kenway put on his clothes and left his Assassin robes in a nearby barrel. It wasn't too bad a fit, considering the disguise had come from a dead man, and Kenway put away his conspicuous bow and other sword behind the wooden barrel where his robes were hidden.

The other sentries off duty in the tower paid him no attention in his disguise as they played cards, and as Kenway went out of their sight, he pulled out a map his contact within the French army had drawn for him. He had quite a ways to go to get to Jean-Louis Dubreton…
