Berger, however, proceeded with the certainty of one long familiar with the locality.
"Here is one of our defence trenches," said Captain Ribaut, halting at last and calling softly to Berger to stop.

"This is our fifth line trench, formerly our third line.

We have no men here, you will note, nor in the next line.

In case of a heavy general attack men would be rushed up from the rear to occupy these two lines of trenches.

We will proceed, Berger." They were soon at the fourth line trench.
