The author Karl Kiesel addresses the period of the Thirty Years' War in the Vosges in this work. From the preface: The following pages contain a modest contribution to the assessment of the Vosges border. They were created on the Maashöhen, in the Argonne, and at La Bassée, and may that excuse their shortcomings. The references were often taken from French sources, as enemy concessions are the most convincing. The inevitable notes are compiled at the end of the text.
