Breaking the stalemate of the Orcs and goblins, is the Orc lord shouting out an order.
Following the orders of the Orc lord (representative), some of the Orcs raised their hands up and pulled it towards themselves.
The Goblin king and his Goblin subjects were surprised at the Orcs acts.
from the Goblins point of view, what the Orcs did was raise their hand and hit their chest with it.
Why?...
The Goblin king questioned their reasoning for acting in such a way.
"have they gone mad?".
The Goblin king said, but he knew that could not be the case.
Not too long, they stood courageously before he and his army, boosting of how they were going to be put down by them.
To say such an army have gone mad is indeed right in the sense of being courageous.
But mad in the sense of cowardice is what the Goblin king is referring to now, their actions right now is akin to that of a coward.
The Goblin king knew that could not be the case.
