"On the 24th [June 1918], after shooting down a kite-balloon over the Lys, at Warneton, to the south of Ypres—incidentally the observer stayed on in the basket to fire at me with a small machine-gun, jumped too late, and was caught up and enveloped in the flaming gas-bag—I was clumsily attacked by a Hannoveraner that dived upon me from on high, firing as it came. Carried away by its speed, it overshot me and had no time to turn before I got into position on its tail, and opened fire at point-blank range. It broke up in the air and crashed near the Bois de Ploegsteert. This mixed brace, my ninth and tenth victories, had cost me six 1 mm. bullets. . . ."
Excerpt from Flying in Flanders, a memoir by Willy Coppens, Belgium's greatest ace in World War I with 37 victories, all but two of the victims observation balloons. After repeated attempts to bring down a balloon, Coppens was finally successful on May 8, 1918 after being provided with 20 French incendiary bullets, bullets he used sparingly. Observation balloons were tethered like a kite, and heavily defended with anti-aircraft guns and fighter planes. The Hannoveraner was likely either a Hannover CL.II or CL.III, a two-seater with a distinctive biplane tail, unusual for a smaller plane. Warneton, Belgium is on the Lys River and the French border, about 13 km south of Ypres.
