The French method of aerial maneuvering is interesting as well as effective. Their air squadrons operate in the following manner: ten machines rise 6,000 feet along the enemy's line; ten others rise 9,000 feet. If an enemy machine attempts to pass the Frenchmen attack simultaneously from above and below, while, if necessary, two other machines come to their aid. Thus the intruder is always at a disadvantage. On several occasions the Germans attempted to fly across the French lines in force, but always with disastrous consequences. When the French set out in squadrons to make a raid or bombard a position they pursue the same tactics and achieve very important results.
Early in September, 1915, General Joffre paid a visit to Rome, was received in audience by King Victor Emmanuel, and decorated with the highest Italian military distinction--the Grand Cross of the Military Order of Savoy--as proof of his majesty's esteem for the French army. General Joffre afterward made a tour of the Italian battle front and conferred with General Cadorna.
About September 8, 1915, the Germans recommenced to attack in the Argonne, where the German Crown Prince had failed to break the French line in June and July. After a violent artillery preparation, including the use of a large number of asphyxiating shells, two infantry divisions were flung against the French. The Germans rushed the first-line trenches at several points. Strong attacks were launched against them and prevented any further advance.
French and British airmen raided the aviation sheds at Ostend; another air squadron dropped sixty shells on the aviation ground at Saint Medard and on the railway station at Dieuze, in Lorraine, twenty-five miles northeast of Nancy. A bombardment of Zeebrugge by the British fleet caused much damage, the Germans losing forty dead and some hundred wounded. Here the submarine port, with two submersibles and two guns on the harbor wall were destroyed, while the central airship shed, containing at the time two dirigibles, was also severely damaged. The semaphore tower was shot to pieces and some sluices crippled. Perhaps the most exciting incident at this period was the great allied air raid on the Forest of Houlthulst, about halfway between Ypres and Dixmude. The forest was quite sheltered from the ravages of the allied guns, and had been converted into a regular garrison district, with comfortable barracks full of soldiers, provision stores, and large munition depots. The whole camp was brilliantly illuminated with electric light.
