what evidence is there that the youth fear of battle and his own merit within battle are increasing

Henry continues to think as the regiment marches. He feels threatened by the landscape. He sees it as full of fierce-eyed enemies. All of a sudden, he is full of distrust of his commanders. He is sure they have led the men into a trap. He must get out; he must be the sole eyes and ears aware of this danger.Henry's feelings remain ambivalent and shifting. He almost always has some opinion or thought about battle, but they change often. In this chapter, they change at least three times, from fear and dread upon seeing the battle, to anticipation of an actual fight, to frustration when the men are being withdrawn.

Henry's manner begins to become more outward in this chapter as well. This will come to bear later in the book, but he starts to act less and less in his head. This is not through his doing.
