3rd. Lastly, a line of men with entrenching tools.[B]
66.—Method of advance.
Proceed by short leaps making use of available protection and crawl flat on the ground in approaching the enemy's trench.
67.—Capture of the enemy's fire trench.
After the defenders in the fire trench are killed, jump in, throw bombs into the dugouts, pursue the enemy into the support and communication trenches.
68.—Organize it against the enemy.
Let then the engineers block up to the right and left the captured trench and organize it rapidly against the enemy, making it face about (through changing the parados into a parapet). The enemy is pursued as far as possible and kept away while fatigue parties from the rear bring up all necessary ammunition, sand bags, barbed wire, etc., carrying back all the captured enemy material. Other fatigue parties start at once to connect the former fire trench with the captured trench by communication trenches.
