Love Among the Ruins by Warwick Deeping

August came in with storm and rain, and a dreary wind blew from the south-west, huddling masses of cloud over a spiritless sky. Southwards, the sea tumbled, a grey expanse edged with foam, its great breakers booming dismally upon the cliffs. The wind swept over Gambrevault, moaning and wailing over battlement and tower, driving the rain in drifting sheets. The bombards still belched and smoked under their penthouses, and the arms of the catapults rose and fell against the sullen sky.

The eighteenth night of the siege came out of the east like a thunder bank, and the grey shivering ghost of the day fled over the western hills. When darkness had fallen, the walls of Gambrevault were invisible from the trenches. Here and there a light shone out like a spark in tinder; the sky above was black as a cavern, unbroken by the crack or cranny of a star.
