His luck was great, as the number of these alpha holes weren't that high, only twenty. He sent his armies there, so he could now control them at the same time, while preparing for the huge battle to come.

That wouldn't work, and the leaders of this kingdom must be feeling quite humiliated right now with his actions, so the first and logical order to give was to force their way through his blockade, even if they sacrificed half of their fleet.
