What words and phrases does the author use to show the violence of the scene in which Buck meets the man "with a red sweater"?

1) That was the man, Buck divined, the next tormentor, and he hurled himself savagely against the bars. The man smiled grimly, and brought a hatchet and a club.

2) Buck rushed at the splintering wood, sinking his teeth into it, surging and wrestling with it. Wherever the hatchet fell on the outside, he was there on the inside, snarling and growling, as furiously anxious to get out as the man in the red sweater was calmly intent on getting him out.

3) And Buck was truly a red-eyed devil, as he drew himself together for the spring, hair bristling, mouth foaming, a mad glitter in his bloodshot eyes.

4) A dozen times he charged, and as often the club broke the charge and smashed him down.
