Perhaps one of the most impressive French memorials in the Salient is that of the French pilot Georges Guynemer in Poelkapelle. Guynemer was one of the great pioneers of aerial warfare with 53 victories, some of his most notable in the skies above Poelkapelle. It was here that he disappeared on 11 September 1917 during a routine mission. His body was never recovered. The Guynemer monument was inaugurated on 8 July 1923 and is crowned by a graceful stork - a reference to the great ace's squadron: l'Escadrille des Cigognes.
