At the two extremities of the port, in order that their fires should converge upon the great axis of the ellipsis formed by the basin, in the first place, two batteries had been raised, evidently destined to receive flank pieces, for D'Artagnan saw the workmen finishing the platform and making ready the demi-circumference in wood upon which the wheels of the pieces might turn to embrace every direction over the epaulement.
Ten Years Later by Dumas, Alexandre View in context
The wide expanse that opened out before the heights on which the Russian batteries stood guarding the bridge was at times veiled by a diaphanous curtain of slanting rain, and then, suddenly spread out in the sunlight, far-distant objects could be clearly seen glittering as though freshly varnished.
War and Peace by Tolstoy, Leo View in context
Harling was very indulgent; bought him guns and tools and electric batteries, and never asked what he did with them.
My Antonia by Cather, Willa View in context
