Bayonets, muskets, and Assassins? Akame ga kill / The Kingdom of Prussia)

Prologue 1 - Waterloo (Outdated)

Y/N POV

"The guard has broken!" I'd hear a soldier shout.

In my mind, I rejoice. This is it! The war is over! Finally, Napoleon's reign has come to an end! We'll march on to Paris by next week! Not yet, I'd tell myself, we must rout the frogs first. Riding up to a colonel, I exclaimed:

"Well, what are you waiting for? They won't stand! Rally all the horse you have, and ride down those Frenchmen! Peirce their lines, they'll break quickly! Go on now!"

With a salute, the Colonel responded by raising his saber, calling on all the hussars under his command to rally.

I'd take out my spyglass, observing them as they galloped forward. As I predicted, the French lines were routed quickly, as losing the Garde Imperiale tanked their morale. Riding back to Generalfeldmarschall Blucher, I'd relay the good news.

Blucher: "Well done!" He'd pat me on the back. "We've won the day, this was a decisive victory." Suddenly becoming serious, he'd then turn to me. "Now then, I know you wish to go home, but a soldier's duty never ends, how would you feel about commanding an expeditionary force into a new continent?"

I'd ponder my choices, do I go home or take this offer? Thinking back, I don't have much at home, I've never been married, nor had any children. There's nothing back there to look forward to. Making my choice, I'd turn towards the Generalfeldmarschall.

"I'll accept the position, sir!"

He'd chuckle, then pull out a letter, handing it to me.
Blucher: "You don't need to call me sir anymore, Y/N."

I'd take the letter, reading it. It read:

FREDERICK THE THIRD, by the Grace of God of the Kingdom of Prussia King, Defender of the Faith.

To: Generalmajor Y/N

Generalmajor Y/N, you are now hereby appointed an Officer in His Majesty's Prussian Armed Forces.

With Seniority of a Generallieutenant, on the day of June 18, 1815.

We reposing especial Trust and Confidence in your Loyalty, Courage and Intergrity do by these Presents Constitute and Appoint you to be an Officer in our Prussian Armed Forces. You are therefore carefully and diligently to discharge your Duty as such in the Rank of  Generallieutenant or in such other Rank as We may from time to time hereafter be pleased to promote or appoint you to, and you are in such a  manner and on such occasions as may be prescribed by us to - Blah Blah Blah.

By Command of His Excellency the Chief of Prussian General Staff.

Reading this, I was jubilant, I rose quickly through my military career, being the youngest member of the General Staff at just 38. Now, I was a Generallieutenant, and even more seniority.

Blucher: "With that, you are now in total command of the 7th Corp, to be shipped to this foreign land, after we take Paris of course! Now then, rally your men! We'll chase these frogs all the way, my children!"
