At length the long summer twilight closed, and the pitying night drew her veil over the horrors of the scene. Still, amid the darkness, the stubborn contest raged. The American and British guns were almost muzzle to muzzle. Some of each were captured and re-captured in fierce hand-to-hand fights, the gunners being bayoneted while serving their pieces. About nine o'clock, a lull occurred. The moon rose upon the tragic scene, lighting up the ghastly staring faces of the dead and the writhing forms of the dying; the groans of the wounded mingling awfully with the deep eternal roar of the neighbouring cataract. The retreating van of Riall's army now returned, with a body of militia--twelve hundred in all. The Americans also brought up fresh reserves, and the combat was renewed with increased fury. Thin lines of fire, marked the position of the infantry, while from the hot lips of the cannon flashed red volleys of flame, revealing in brief gleams the disordered ranks struggling in the gloom. By midnight, after six hours of mortal conflict, seventeen hundred men lay dead or wounded on the field, when the Americans abandoned the hopeless contest, their loss being nine hundred and thirty, besides three hundred taken prisoners. The British loss was seven hundred and seventy. To-day the peaceful wheat-fields wave upon the sunny slopes fertilized by the bodies of so many brave men, and the ploughshare upturns rusted bullets, regimental buttons, and other relics of this most sanguinary battle of the war. Throwing their heavy baggage and tents into the rushing rapids of the Niagara, and breaking down the bridges behind them, the fugitives retreated to Fort Erie, where they formed an entrenched camp. [Footnote: Withrow's "History of Canada," 8vo. Ed., pp. 323-333.] We must now return to trace the individual adventures in this bloody drama of the personages of our story. Every possible provision that wise foresight could suggest had been made for the defence of the Niagara Frontier. Fort George had been strengthened and revictualled. A new fort--Fort Mississauga--with star-shaped ramparts, moat and stockade, had been constructed at the mouth of the river. Its citadel is a very solid structure, with walls eight feet thick, built of the bricks of the devastated town of Niagara. A narrow portal with a double iron door admits one to the vaulted interior of the citadel, and a stairway, constructed in the thickness of the wall, conducts to the second storey or platform, which is open to the sky. Here were formerly mounted several heavy guns, and the fire-place for heating the cannon-balls may still be seen.
