It's so hard to take this seriously when the casualty number is 4.
He's standing in front of the emperor to talk about a battle where thirty thousand of his people were killed, and he goes on to make a grand speech and say... Even four of my own soldiers died. Truly, it was a tragedy.
Like, hello? 4 is a rounding error at this level of scale. You should've expected four casualties on a successful mission, and instead you're bemoaning it as a serious loss on a suicide one. The emperor should be laughing him out of the room, regardless of his accomplishments.
