On October 28, 1916, it was announced that Captain Boelke, the famous German aviator, had been killed in a collision, with another aeroplane. He was credited with having brought down forty aeroplanes. Not until almost the middle of November, 1916, did aeroplane warfare develop its usual activity. On the night of November 9-10, 1916, British aeroplanes dropped bombs without success on Ostend and Zeebrugge. One British machine was forced down and captured and the aviator, a British officer, made prisoner. On the morning of November 10, 1916, a German battleplane attacked two British biplanes between Nieuport and Dunkirk. It shot down one and forced the other to retreat. In the forenoon three German battleplanes met a superior British aerial squadron off Ostend and attacked it. After a combat the British were forced to withdraw. The German machines returned to their base, having suffered insignificant damages. Between 10 and 11 o'clock on the morning of November 10, 1916, a group of seventeen British aeroplanes bombarded the steel works at Voelklingen, northwest of Saarbruecken. One thousand kilograms of projectiles were dropped on the buildings, which were damaged seriously. In the course of the operations British machines fought several actions against German machines, three of which were felled. On the following night between 8 and 9 o'clock eight British aeroplanes executed a fresh bombardment of these works, dropping 1,800 kilograms of projectiles. Several fires were observed. All British machines returned safely. During the night of November 10-11, 1916, British squadrons drenched with projectiles the stations of Ham, St. Quentin, Tergnier, and Nesle, in the Somme region, and the aerodrome at Dreuze, the blast furnaces of Ramsbach, the aeroplane sheds of Frescati (near Metz), and the blast furnaces of Hagodange (north of Metz). These operations caused great damage, and several explosions and fires were observed. A German aeroplane during the night of November 10-11, 1916, bombarded several French towns. Nancy and Luneville received projectiles which caused damage or casualties. Amiens was also bombarded on various occasions during the same night. Nine persons of the civilian population were killed and twenty-seven injured. On November 11, 1916, five German machines were claimed to have been brought down by the British. The following day, November 12, 1916, a squadron of British naval aeroplanes attacked the harbor of Ostend. A considerable number of bombs was dropped on the dockyards and on the war vessels in the harbor. On the same day it was also reported that two successful air raids had been carried out by aircraft operating with the British forces in Egypt. The points raided were Maghdaba and Birsaba. A ton of high explosives was dropped. Two Fokker machines were brought down by the raiding aeroplanes, all of which returned safely.
