The human commander sat in the saddle and observed the situation. He wasn't afraid of charging Orks, or as he called them Trolls. He fought many times with enemies that were simple-minded brutes and that would charge his lines. Even if they broke through they would lose because he had more men, twice as much as the Troll(Orks) actually, and eventually seeing the loss of their brethren would break their spirit. Usually 1/4 of the enemy would die in a charge from arrows and then they would clash with heavy infantry and smash into their shields and die. Then the enemy would run away. He would then follow up and kill everyone. That's what was supposed to happen. His archers shoot a volley of arrows, but it only spilled a little bit of blood. He wanted to order a second volley but Trolls(Orks) were already smashing into his man. Swords were barely able to cut the thick Orcish skin, and even then blood would quickly form a blood cloth and made them even more violent and loud. The biggest one was especially scary as he would simply smash his club around and if not outright killed a soldier he would heavily wound or cripple them.
From Orc side they saw a lot of umies. All were armed and ready to fight. There was more umies than Orks but it did not matter as this would make fun longer, bloodier, and funnier. Also Orcs did not care if somehow one of them was wounded. That wounded Orc was simply stupid and weak so he deserved it. All Orcs had fun, but the most fun had Boss.
Boss was inside the biggest crowd. He smashed left and right as the were lotz of umies round `im dere. Blood would splatter around him and other Orcs making them quicker on their feet.
The fight went on until humans started too break ranks and run away. The human commander decided to take action. His target was the biggest Troll(Ork). He blew his warhorn and took out his sword. All soldiers started to retreat leaving a big place for their commander to fight. The human leader pointed his sword at Boss and called him to a one-on-one fight. The primitives always wanted it, and he never lost. He decided that this green monster will be slain by him personally.
When Boss saw that the humans started to retreat he was confused at first as the fight was so fun. He did not understand how you may not like it. Then he saw the biggest umie on a horse pointing his sword at him. He understood it immediately. This fight will be resolved by one on one battle. Boss answered with one thing that came to his mind - WAAAAAAAAAAAAAAAGHHH and run towards the umie. Somehow other Orcs also understood the meaning of what was going on and stopped fighting. All their eyes were focused on their boss, and when he went WAAGH they did it too.
Two leaders were closing on each other, humans on his horse had height advantage and decide to use it. He kicked the horse making him jump forward and swung his sword aiming for Boss`s head. Boss from the beginning wasn't planning on fighting fair. Well, he wanted to fight fair but on his terms, and the horse that umie was on wasn't fair. So when horse jumped and was about to land, the sword was about to hit his head. He was prepared with an upper swing. The clobba hit the horse in the throat so hard that it caused the spine to brake thru the skin.
The human wasn't expecting such power and lost balance making him miss the head and lightly tap the shoulder that was covered in leather armor, doing nothing. However, the commander quickly regained his balance and jumped off the saddle. The horse fell dawn and died on the spot. Now both fighters were on even ground. Boss smiled and windmilled his clobba over his head creaming WAAAAAAAAAAAAAGHHHH.
Human watched terrified as his enemies readied for a fight. He was weaker and slower, the technique he was so proud of wasn't going to help him if his enemy could simply smash his horse with one swing.
Orc did not wait any longer and jumped at puny umie. The annoying pest dodged but was too slow to dodge another hit. The clobba hit him in the knee. - Nuw, ya gunna die!
-Mercy?- Asked human/. - At least let my man go?
He got no response as Boss smashed his head like a tomato. The body fell down and the human spirit totally broke. They started to run away without any sort of organization. Orks seeing this started to chase them. Maybe there would still be some fight to do, or they could get their hands on some good loot. They did not care, as today was fun. In the forest, only WAAAAAAAAAGHHH and screams of killed humans could be heard.
