Slingsby frowned, but said nothing as Sharpe climbed the ladder to the mast's platform that stood fifteen feet above the hilltop. Three pock marks in the boards showed where the Midshipman had placed his tripod so he could stare at the neighboring telegraph stations and read their messages. The station to the north had already been destroyed, but looking south Sharpe could just see the next tower somewhere beyond the River Criz and still behind British lines. It would not be behind the lines for long, he thought. Marshal Massena's army was flooding into central Portugal and the British would be retreating to their newly built defensive lines at Torres Vedras. The plan was to retreat to the new fortifications, let the French come, then either kill their futile attacks or watch them starve.

And to help them starve, the British and Portuguese were leaving them nothing. Every barn, every larder, every storehouse was being emptied. Crops were being burned in their fields, windmills were being destroyed and wells made foul with carcasses. The inhabitants of every town and village in central Portugal were being evicted, taking their livestock with them, ordered to go either behind the Lines of Torres Vedras or else up into the high hills where the French would be reluctant to follow. The intention was that the enemy would find a scorched land, bare of everything, even of telegraph ropes.

Sharpe untied one of the signal ropes and pulled down the white flag that turned out to be a big handkerchief of fine linen, neatly hemmed with the initials PAF embroidered in blue into one corner. Ferreira? Sharpe looked down on the Portuguese Major who was watching him. "Yours, Major?" Sharpe asked.

"No," Ferreira called back.

"Mine then," Sharpe said, and pocketed the handkerchief. He saw the anger on Ferreira's face and was amused by it. "You might want to move those horses," he nodded at the beasts picketed beside the shrine, "before we burn the tower."
