 This book (published with the explicit consent of King William II as a semi-official rebuttal), was received with much enthusiasm in Dutch military circles.When soon thereafter there was a false rumor in the Dutch press that captain Siborne was on his way to demand satisfaction, no less than six officers of horse-artillery spontaneously offered to act as Knoop's seconds, if necessary.Knoop's book was soon translated in French and German, and met with much interest in France and Prussia at the time.
