In 1809 French armies controlled almost every province of Spain and only
Wellington's small force in Portugal stood between Napoleon and the
conquest of Iberia.
The French invaded Portugal in the summer of 1810 but found their way
blocked by the most extensive field fortifications the world had ever
seen - the Lines of Torres Vedras. Unable to penetrate the Lines, the
French were driven back into Spain having suffered the heaviest defeat
yet experienced by Napoleon's armies. The retreat from Portugal marked
the turning point in the Peninsular War and, from the security of the
Lines, Wellington was able to mount the offensive campaigns that swept
France's Imperial armies back across the Pyrenees.
The Lines of Torres Vedras is an authoritative account of the planning,
construction and occupation of the Lines and of the battles, sieges and
horrors of the French invasion. It is also an important study of
Wellington's strategy during the crucial years of the war against
Napoleon.
