Exactly. Who the fuck goes "Let's pick a fucking fight with 3m tall battle puppet. I bet we can take it!"
Like "We've seen the puppet deployed before, ALSO us and the enemy have secret weapons... so its actually not even a surprise to see it... we already know it fucking BUZZSAWED through people last time. But this time? We have horses! That will do the trick!"
My brothers in christ, did you huff too much fucking dragonfire smoke or are you this full on fucking stupid always?
Going out of their way to attack the 3m tall figure that's just standing there?
1. These soldiers have probably not seen the Sword Puppet deployed. They're the reserve forces left behind while Prince Reinhardt went out. (Chapter 44, page 21). These princes, don't really know the specifics, just a "mysterious group" countered all their new tactics. They don't seem to know that the wyverns were attacked on their own walls. Chapter 44 Page 27, Panel 2, they specifically say, they were only told what happened. So, they might not even know the Puppet is a puppet. Just some ridiculously tall person in an armor dress that was inhumanly strong and fast.
2. They're retreating towards the mountain road, behind Scudet. The smartest move to do that is to use the treeline so you won't get sniped by archers. They were just unlucky enough that that was where the Sword Puppet was on standby. And they're escorting a Prince. Of course you attack. You're worried they're chasing you down. Your honor depends on defending him. Do you think you're rushing past the 3m tall lady you heard killed wyverns in a single hit? You rush to distract them and let the Prince escape. Of course it's a bad choice, but it's the least bad choice for their situation.
On a separate note, this is definitely Prince Bashiz. Chapter 45.1 page 2, Freightliner has noped right out of there.
