Originally published by William Clowes & Sons in 1908, Campaign in Bohemia, 1866 by T. Miller Maguire provides a concise tactical and strategic study of the Austro-Prussian War, or Seven Weeks' War. Focusing on the Bohemian theatre, Maguire traces the rapid campaign that culminated in the decisive Battle of Königgrätz (Sadowa), one of the largest European battles of the nineteenth century. The narrative follows the opposing movements towards Königgrätz before examining the wider consequences of the Prussian victory, which ended Austria's predominance among the German states and established Prussian ascendancy. Maguire also highlights the campaign's significance as a landmark in military modernisation, examining the practical impact of breech-loading rifles, steel-rifled artillery, the electric telegraph and the strategic use of railways. At 42 pages, this compact study offers a focused account of a campaign whose operational methods and technological innovations had a lasting influence on European warfare.
