Love Among the Ruins by Warwick Deeping

It was dawn; mists covered the forest; not a wind stirred or sobbed amid the boughs. A vast grey canopy seemed to tent the world, a mysterious veil that tempered the sun and spread a spiritual gloom over rock and tree.

The noise of horns played through the misty aisles -- horns many-tongued, faint, clamorous, like the trumpeting of forest elves. There was the dull, rhythmic onrush of many thousand feet, the hurrying, multitudinous tramp of men marching. Armour gleamed through the glooms; casque and bassinet, salade and cap of steel flowed on and on as phosphorescent ripples on a subterranean stream. Pike, glaive, gisarme shone like stubble over the forest slopes. The sullen tramp of men, the clashing clamour of arms, the blaring of a solitary clarion, such were songs of the great pine forest on that July morning.
