This article re-examines the adoption of Hussite Wagenburg-warfare in the army of King Matthias of Hungary. While Hungarian historiography traditionally assumes the transfer of both war wagons and their associated tactical system, this study argues that only the device, not the method, was adopted. By analysing key engagements from the eras of John Hunyadi and Matthias – including the Battle of Varna (1444), Kosovo Polje (1448), Baia (1467), and the Breslau campaign (1474) – it demonstrates that wagon forts consistently played a secondary, primarily defensive role. Rather than functioning as an integrated tactical framework, they served as mobile fortifications. The presence of experienced mercenary commanders further suggests that this limited adoption cannot be explained by a lack of technical knowledge.
