“But four fortress guns,” Elphinstone said harshly, “could slice a Battalion to mincemeat. I’ve seen it!” Implying, evidently truthfully, that Wigram had not.

“If we imagine disaster,” Bampfylde said smoothly, “then we shall allow timidity to convince us into inaction.” The comment implied cowardice to Elphinstone, but Bampfylde seemed oblivious of the offence he had given. Instead he unrolled a chart on to the table. “Weight the end of that, Sharpe! Now! There seems to me just one sensible way to proceed.”

He outlined his plan which was, indeed, the only sensible way to proceed. The naval flotilla, under Bampfylde’s command, would sail northwards and land troops on the coast south of the Point d’Arcachon. That land force, commanded by Sharpe, would proceed towards the fortress, a journey of some six hours, and make an escalade while the defenders were distracted by the’incursion of a frigate into the mouth of the Arcachon channel. “The frigate’s bound to take some punishment,” Bampfylde said equably, “but I’m sure Major Sharpe will overcome the gunners swiftly.”
