Aeon planned to separate the Orc Soldiers from the Orc Sergeant because most Orc Sergeants have a skill that could raise the battle morale of his Orc Soldiers.
So, with his current strength, even with the help of the Goblin Sergeant and his group, he won't be able to take down all the Hornless Orcs at once.
Hence, he planned to kill the two Orc Soldiers and made the remaining ones chase his Summoned Goblin Soldiers while he and his Goblin Followers took care of the Orc Sergeant.
'Swoosh'
Aeon silently went to his Goblin Followers and informed them about the Orc Group along with his plan to kill the Orc Sergeant before the Orcs returned.
"Captain Aeon, do you think we can kill an Orc Sergeant?"
Hearing Aeon's plans, one Goblin Soldier asked Aeon after some hesitation.
Even though the other Goblin Soldiers didn't say it out loud, they all had the same doubts regarding Aeon's plan.
