I hope someday there will be no fighting and we can all just...nap the afternoon away...

Caspar

Don't worry about me... I always knew...losing meant death...

Imperial Soldier

Report! A group posing as Imperial soldiers has infiltrated! They seem to be affiliated with the church!
Death Knight
volume_up

Close the gates. Leave no survivors.

Imperial Soldier
volume_up

General, reinforcements have arrived from the capital.
Imperial Soldier
volume_up

They clashed with Alliance forces in the outskirts of the city, but should enter the fortress soon.
Death Knight
volume_up

You let them in? Make haste and slaughter them all.
Imperial Soldier
volume_up

Huh? Why?
Death Knight
volume_up

They are enemies. Slaughter them all. I will not say it again.
Claude
volume_up

We made it in. Professor, take control from the south.
Claude

I have my own task to do from here. There are preparations to be made for our secret plan.

I see your skills haven't dulled yet, kiddo.
What did you expect?
Everyone, listen up!
From now on, the Almyran forces will be fighting by our side!
We'll work as one! And we will bring down that fort together!

Claude
volume_up

An impregnable fortress is a wide-open prairie once you get inside. From here, we'll attack from the north and south at once!
Nader
volume_up

No different than a prairie, you say? Heh! You've got a strange head on your shoulders, kiddo.
Claude
volume_up

For Nader the Undefeated, this should be as easy as a walk in a meadow, right?
Nader
volume_up

Heh. Well, goddess or death god or whoever they may be, let's crush them to dust.

Enemy reinforcements will appear from all sides of the fortress.
If you move one of your units to the space where enemy reinforcements enter the battlefield, you can stop them from appearing there.

Seteth
volume_up

We've come this far—we cannot let him escape now! Everyone, after the Death Knight!
link
Claude
volume_up

He's hiding something... It's annoying to do what he's telling us to, but we don't really have a choice. After him!
link
Death Knight
volume_up

The time is ripe.
link
Seteth
volume_up

Do not let him get away! Circle around and cut off his retreat!
link
Alliance Soldier
volume_up

Report! The Death Knight is moving! It looks like they're abandoning the fortress and making an escape!
Claude
volume_up

We need to put an end to this here and now. Come on, let's circle around and cut off his retreat.
link
Death Knight
volume_up

The time of ruin draws near... But their slaughter must wait until next we meet...
link
Seteth
volume_up

He's fled, has he? Let us deal with the remaining foes and then make haste in our pursuit!
link
Alliance Soldier
volume_up

Report! The Death Knight has escaped the fortress!
Claude
volume_up

He gave up too easily. Does he have some other plan? Let's deal with the remaining enemies and go after him, quickly!

It is coming...
Leave now or all of you will die.
Run!
We have to evacuate immediately!
What just happened here?
The fort, it's...
It's just...gone.

Attack: Byleth - Death Knight

Death Knight
volume_up

You're stronger now. Whether I kill you or you kill me, I'm looking forward to this!
link

Attack: Claude - Death Knight

Claude
volume_up

Hey, how long's it been? Five years? Who'd have thought you'd end up an Imperial general...
Death Knight
volume_up

So, you wish to die.
Claude
volume_up

Heh. As antisocial and unhinged as ever, I see.
link

Attack: Seteth - Death Knight

Seteth
volume_up

You will not escape, Death Knight. Today you will be unmasked!
Death Knight
volume_up

My true identity has no value.
Seteth
volume_up

I will be the judge of that, once I've seen your face.
link

Attack: Flayn - Death Knight

Flayn
volume_up

So it's you, Death Knight! Remember me?!
Death Knight
volume_up

You again. Here to lose more blood?
Flayn
volume_up

Never! You will not lay a hand on me ever again!
link

Attack: Mercedes - Death Knight

Death Knight
volume_up

You. Leave.
Mercedes
volume_up

No! I won't! I...I refuse to run from you anymore!
link

Attack: Byleth - Caspar

Caspar
volume_up

It's way over my head, and I don't really get what's going on between you and Edelgard.
Caspar
volume_up

I thought for sure you two would come to an understanding, but I guess I was wrong.
link

Attack: Byleth - Linhardt

Linhardt
volume_up

Ever since returning to the Empire, I knew this day would arrive. I just hoped it might take a bit longer.
Linhardt
volume_up

Ugh...
link

Attack: Caspar - Linhardt

Caspar
volume_up

Looks like we ended up on opposing sides, Linhardt!
Linhardt
volume_up

Certainly seems that way. I could almost weep over how things turned out.
Linhardt
volume_up

Do you realize, Caspar, that this is the first time we've ever fought?
Caspar
volume_up

Yeah, I think you're right. The first and probably the last!

Attack: Enemy Units - Caspar

Caspar
volume_up

Did you have to kill a lot of your friends to get here?
Caspar
volume_up

Cause I'm gonna give this fight everything I've got!
link

Attack: Enemy Units - Linhardt

Linhardt
volume_up

I'd rather not fight, yet avoiding it is more frustrating and fruitless than engaging in the battle itself.
link

Attack: Enemy Units - Death Knight

Death Knight
volume_up

I have no need of you.
