what does he see that he resents and envies

A column of troops comes up in the road, heading in the opposite direction. They push themselves through the fleeing wagons towards the enemy. These men bring Henry's feelings of inadequacy back. He feels that these are chosen beings, marching in the sunlight. He could never be like these men. He feels that the final blame for his condition lies on some unnamable thing. He wonders why these men would be in such a hurry to get to the battle. Henry grows more envious. He wishes a tremendous force would throw him off, leaving a better person. He can see pictures of this more fleet and heroic soldier he would make. He feels the desire to fight again.
