A Good Strategy: Pincer Attack

Deoras and his pack then almost immediately went towards the right. As they were explained, they would attack from the right side.

Whereas for the goblins, Shin gave the orders to move towards the left side. He had given the commanding position to Arzoo and Mirza.

It was actually best to have just a single commander, but Shin decided to go with two. He had actually divided the goblin troops into two so it was understandable. Also, it was seen that these two were Shin's favorites so there was no reason for him not to choose them.

Whatever, Shin was probably planning to launch a pincer attack. He would alone press from the front, while the wolves and the goblins would attack from the sides.

The reason why Shin left the back open was that he didn't want to needlessly massacre the humans. Surely he hated them, but he surely knew that there were some good ones and those that had many things and uses in the future.
