How does David Chotjewitz use imagery in Daniel Half Human?

"There was no more street, just a path through massive piles of rubble. My jeep couldn't get through. I put it in reverse, backtracked, and turned off to the right" (June 1945, I, p. 1).

"Daniel kept looking left and right. It was so cold, his eyes were watering. The teardrops froze hard on his cheeks. He wiped his face with his glove, and then he heard something - faint, still far away. It sounded like marching" (Painting, p. 10).
