The woman was trying to fight off one of the orks who was attacking her, but she knew she was not able to defeat this ork in her current wounded state.
However, before she was about to get to hit, the attacking ork got pulverised as a sudden thunder hammer hit its head point blank, killing the ork, making its body get blown away by the force of the hit.
"M-my lord Astartes! Forgive me, I was-" The woman said with a bit of a frightened voice but was interrupted.
"Status!" The space marine captain told her firmly, as his figure was towering over her.
"Right, I was scouting ahead when I noticed the natives of this world and the orks clashing in a battle, but it seems those aliens are starting to drive the orks back." The woman responded, snapping back to attention.
"You must know your enemy to defeat them, Orks only retreat to regroup, they will keep coming until either you or they are dead." He replied "Head to the Apothecarion and see to it that your wounds are tended to. We will take it from here."
"Of course my lord, forgive me if I speak out of place, but..... What is your next course of action? Wouldn't it be wise to wait until the battle has ended, and then take action?" She asked.
"And risk the opportunity for those greenskins to regroup with their bigger horde? No, we are here to slay every single of those orks, we WILL succeed, natives involved or not." The Captain said with resolution.
None of these events were happening close to the actual battle itself, but eventual contact would become apparent soon...
------------------------------------------------------------------------
The orks were starting to retreat back into the forest, though it was apparent that this was a rather mild assault for ork standards, which meant this assault force had only been a group of recently regrouped orks.
Around only 50 remained, while there quite a few losses to the royal guard as well during this conflict, in theory the defenders of the train location where safe, but would they hun down the last remaining attackers, or do something else?
