This is the part where their noble Littenheim is losing the battle and chooses to run away, but his escape path is blocked by his own supply ships. Instead of just going through them, since space is big and all, he instead opens fire on them. Right before this we get a scene with two guys, one of them showing a picture of his wife and newborn twins to the other, commenting on how he wants to go home and hold them soon. Both of them are then killed in the attack by their own forces. Now that’s just brutal right there.
