What is Ralph's behavior during the attack by Jack's boys?

Wheh Jack and his hunters attack the shelter. Ralph's boys fight them off but suffer considerable injuries. Piggy tells Ralph that they wanted the conch, but he then realizes that they came for something else: Piggy's broken glasses.

Ralph hit out; then he and what seemed like a dozen others were rolling over and over, hitting, biting, scratching. He was torn and jolted, found fingers in his mouth and bit them. A fist withdrew and came back like a piston, so that the whole shelter exploded into light. Ralph twisted sideways on top of a writhing body and felt hot breath on his cheek. He began to pound the mouth below him, using his clenched fist as a hammer; he hit with more and more passionate hysteria as the face became slippery. A knee jerked up between his legs and he fell sideways, busying himself with his pain, and the fight rolled over him. Then the shelter collapsed with smothering finality; and the anonymous shapes fought their way out and through. Dark figures drew themselves out of the wreckage and flitted away, till the screams of the littluns and Piggy’s gasps were once more audible.
