Not sure if this is spoilers or not, but
Ashford
is referred to as "incompetent" at least once. It seems, though, that he was just given a bad lot. For example,
Bull was insubordinate in the sick bay and, in a normal situation, Ashford should have cracked down hard. There was no real reason to trust anyone else in the flotilla to send over only their injured and unarmed. As a captain, didn't Ashford react as he was supposed to?
In addition,
When the Roci was broadcasting the message about the Seung Un, Ashford did not want to fire on them. That makes some sense - another ship was claiming to be OPA and threatening the flotilla's ships, the Behemoth was totally untested and, when it fired, it broke the ship. Ashford not wanting to fire seemed like a prudent move
So what was it about his actions that were "incompetent"?
