Note 521 — Chapter IV · BAYEZID THE OSMANLIS INHERIT THE BYZANTINE EMPIRE
Reading edition
Lavisse, Histoire de France, iv. 311: ‘on l’avait vu à la bataille de Nicopoli sur les bords de la Baltique avec les chevaliers teutoniques.’ Lavisse has evidently mixed up the Nicopolis expedition with the earlier Prussian one in which Henry did take part. His statement on the same page that Henry IV took part in the Boucicaut expedition is another error.
