Les sieges 2 is the second volume of a two‑part study on military sieges written by Guillaume Janneau and originally published in 1928 by Librairie d'Art. The work examines the tactics, engineering, and historical significance of siege warfare across different periods, drawing on contemporary sources and military theory of the early twentieth century. Though detailed publication information is scarce, the edition notes indicate a French‑language context with an English language listing, suggesting it may have been circulated internationally. Janneau’s approach combines narrative description with technical analysis, aiming to provide readers with both a chronological account and an understanding of the strategic considerations involved in conducting and defending sieges. The volume likely complements the first part by continuing the historical survey or focusing on specific case studies. As a product of its time, the text reflects the interwar interest in military history and the lessons drawn from World War I fortifications, offering insight into how military scholars of the era interpreted past conflicts to inform contemporary thought.
