"Thank you, Captain," Ferreira said icily.

"Fire it now, Sharpe?" Slingsby demanded from the ground.

"Not till I'm off the bloody platform," Sharpe growled. He looked round one last time and saw a small mist of gray-white powder smoke far off to the southeast. He pulled out his telescope, the precious glass that had been given to him by Sir Arthur Wellesley, now Lord Wellington, and he rested it on the balustrade and then knelt and stared towards the smoke. He could see little, but he reckoned he was watching the British rearguard in action. French cavalry must have pressed too close and a battalion was firing volleys, backed up by the cannons of the Royal Horse Artillery. He could just hear the soft thump of the far-off guns. He swept the glass north, the lens traveling over a hard country of hills, rocks and barren pasture, and there was nothing there, nothing at all, until suddenly he saw a hint of a different green and he jerked the glass back, settled it and saw them.

Cavalry. French cavalry. Dragoons in their green coats. They were at least a mile away, in a valley, but coming towards the telegraph station. Reflected sunlight glinted from their buckles, bits and stirrups as Sharpe tried to count them. Forty? Sixty men perhaps, it was hard to tell for the squadron was twisting between rocks in the valley's deep heart and going from sunshine to shadow. They looked to be in no particular hurry and Sharpe wondered if they had been sent to capture the telegraph station which would serve the advancing French as well as it had served the British.

"We've got company, Sergeant!" Sharpe called down to Harper. Decency and courtesy demanded that he should have told Slingsby, but he could barely bring himself to talk to the man, so he spoke to Harper instead. "At least a squadron of green bastards. About a mile away, but they could be here in a few minutes." He collapsed the telescope and went down the ladder and nodded at the Irish Sergeant. "Spark it off," he said.
