Harry was allowed to obtain a few hours sleep in the latter part of the night in one of the captured wagons.

It was a covered wagon and he selected it because he noticed that the night, even if it was the first of June, was growing chill.

But he had no time to be particular about the rest.

He did not undress--he had not undressed in days--but lying between two sacks of meal with his head on a third sack he sank into a profound slumber.
When Harry awoke he felt that the wagon was moving.

He also heard the patter of rain on his canvas roof.
