One of the chief incidents of the fighting this week
in the west has been the energetic use by the Allies of their aero- planes. Thirty-five French aeroplanes on Monday, despite a strong wind, flew over and threw bombs on the strategic rail- way which serves the famous Calonne trench and the German works in the forest of Apremont. They are stated to have thrown a hundred and seventy-one bombs on the German storehouses, and to have caused several outbreaks of fire. The aeroplanes returned safely, though they were vigorously shelled. Later in the week another aerial raid was made on the railway system between Douai and Lille.
