Volume 2 covers Hans-Joachim Buddecke, Kurt Wintgens, and Max Ritter von Mulzer, the third through fifth aviation recipients of the Pour le Mérite. Buddecke spent much of his career in Turkey and is reasonably well known, but the other two aces have received modest coverage until now. Volume 2 includes 168 period photographs and 10 color profiles of aircraft flown by these aces.
