The book "Wellington and the Lines of Torres Vedras: The Defense of Lisbon During the Peninsular War, 1807-1814" by John H. G. Hill is a comprehensive study of one of the most important military campaigns of the Napoleonic Wars, which took place in the Iberian Peninsula between 1807 and 1814. The book focuses on the defense of Lisbon, which was crucial for both the British and Spanish armies fighting against the French invasion. The author provides an in-depth analysis of the strategic decisions made by the Duke of Wellington, who led the British forces, and how his tactics were influenced by the geography of the region and the political situation at the time. The book begins with an overview of the historical context of the Peninsular War, including the political and social factors that led to the conflict, as well as the military campaigns fought before and after the defense of Lisbon. The author then delves into the details of Wellington's strategy, highlighting his use of the Lines of Torres Vedras, a series of fortifications that protected the city from the French army. The book also explores the role of other military leaders and their contributions to the defense of Lisbon, such as the Spanish general Francisco Javier Venegas. Throughout the book, Hill emphasizes the importance of understanding the technological evolution of warfare during this period, particularly the development of artillery and the use of siege engines. He argues that this technological advancement played a critical role in the success of Wellington's defense and ultimately led to the defeat of Napoleon's armies in the Iberian Peninsula.
