Kili caught one of the pinecones, quickly shifted it to his other hand, then whipped it at the nearest warg. The rest of the company helped, and soon the clearing was engulfed in a wall of flame. This earned cheers from them all, and Azog roared in fury at their show of resistance. This was not to last, however. The cheers turned into cries of fear as the roots of the tree started to give way; the tree tipped precariously over the edge of the cliff, but stopped, only inches away from the cliff.

Again, Kili almost lost his grip. Holding on at such an angle was becoming impossible, and he was frightened certain that one of them was sure to fall. As if to answer his fears, Dori fell, but he managed to hold on for dear life when Gandalf extended him his staff. 

Thorin would take no more of this. Saeril could not handle them all on her own, nor should she have to. Slowly, he pushed himself up, hatred burning in his eyes. Azog would pay for the grief and torment he had brought to them all.
Through the flames, Thorin ran towards him, Ocrist drawn.
The attack never made its mark; Azog was one step ahead. With the assist of his warg, he was faster, and both attacked Thorin first. Thorin managed to swing his sword, but he was thrown to the ground, then hit with Azog's mace as the others looked on in shock.

"Thorin!" Kili attempted to climb forward in order to reach him, but any movement risked the tree falling over completely.
