enemy line

This spur, strongly fortified by the enemy, made the greater part of the salient in the enemy line.

The opposing lines of trenches go down the slope, much as usual, with the enemy line above on a slight natural glacis.

Our line goes along the top of the ridge here, at a good distance from the enemy line.

This flattish land, well within the enemy line, was the scene of very desperate fighting on the 1st of July.

Our line passes over the spur slightly below it, the enemy line takes in as much of it as the enemy needed.
