"The road is steeper here," said Berger, halting after he had led his party half a mile through the darkness.

"We now go up hill." It was harder climbing, going up that incline.

A quarter of a mile of this, and Lieutenant Terry suddenly found himself following the guide through a cut in between two walls of dirt higher than his head.
"We are in the communication trenches," said Berger in French.

Noll gathered the meaning of the remark.
At every few yards there was a twist or a turn in the trench.
At times they came to points where two trenches crossed each other.

Had it been left to the Americans to find their own way they would have been hopelessly confused in this network and maze of intersecting ditches.
