How we cite our quotes:
"You've done that for me, Joey. Given me back my confidence. Feel I can do anything now. Feel like one of those knights in armor when I'm up on you." (7.7)
Not only is Joey confident himself, but he gives confidence to others, too. He pays attention to Trooper Warren as he rides and compensates for Warren's mistakes so that he doesn't fall off. Because of these subtle corrections, Warren feels like he's improved and can do anything.
We were back among the fearful noise and stench of battle, hauling our gun through the mud. (12.2)
Instinct, both human and animal, practically screams at you to run away from the noise of gunfire and smell of death. But Joey and the soldiers must march toward it. And you know what? Joey never even considers running away.
Our newfound health and the optimism of the singing, whistling soldiers brought us to a fresh sense of exhilaration. (13.2)
Even when facing death, the soldiers find a way to maintain their spirits. The soldiers and the horses feed off the courage of one another to build morale.
