how does the tone of this chapter contrast to the previous

I think in chapter 22, Henry puts all distractions behind him. Rumours, perceptions and odds mean little to Henry. Unlike Chapter 21, Henry is now firm of purpose and duty. He stands strong in the rush and din of battle. Interestingly, the gray phantoms, which haunted him at the first skirmish, are not bothering him now. They are smoke that he can see through. He makes out different parts of the battle and sees how the greater body, that of the army, is engaged even if he himself is not yet fighting.
