Lines of Torres Vedras

Definition and stakes

Most of the heights are capped by towers, and scored along the faces of the mountains may still be discerned lines and marks of earthworks and redoubts. These are the never-to-be-forgotten lines of Torres Vedras, by which the genius of Wellington finally held the legions of Napoleon at bay, and saved Portugal—and incidentally Europe—from the domination of the French.

On the whole, only about £100,000 was paid out between November 1809 and September 1810—so that the Lines of Torres Vedras may be considered one of the cheapest investments in history. The militiamen and peasantry were worked in gangs of some 1,000 or 1,500 men, each in charge of an engineer officer, who had a few English and Portuguese military artificers as his assistants: only 150 such were available, so short were both armies of trained men.

Behind the British army and immediately to the north of Lisbon, in an arc some thirty miles long, following the inflection of the hills from the sea at the mouth of the Zizandre to the broad waters of the Tagus at Alhandra, the lines of Torres Vedras were being constructed under the direction of Colonel Fletcher and this so secretly and with such careful measures as to remain unknown to British and Portuguese alike.
