Two brigades were now in midstream on the Isle of Orleans and one on Point Lévis. Landing artillery and stores, intrenching both positions, and mounting siege-guns at the last-named one consumed the first few days of July. Wolfe's skill in erecting and firing batteries had been abundantly demonstrated at Louisburg; and though his head quarters were on the island, he went frequently to superintend the preparations for the bombardment of Quebec. On July 12th a rocket leaped into the sky from Wolfe's camp. It was the signal for the forty guns and mortars that had been mounted on Point Lévis to open on the city that Vaudreuil and his friends had fondly thought was out of range. The first few shots may have encouraged the delusion, as they fell short; but the gunners quickly got their distance, and then began that storm of shot and shell which rained upon the doomed city, with scarce a respite, for upward of eight weeks.
Houses, churches, and monasteries crashed and crumbled beneath the pitiless discharge. The great cathedral, where the memories and the trophies of a century's defiance of the accursed heretic had so thickly gathered, was gradually reduced to a skeleton of charred walls. The church of Notre Dame de la Victoire, erected in gratitude for the delivery of the city from the last and only previous attack upon it sixty years before, was one of the first buildings to suffer from the far more serious punishment of this one. Wolfe, though already suffering from more than his chronic ill-health, was ubiquitous and indefatigable; now behind Monckton's guns at Point Lévis, now with Townshend's batteries at Montmorency, now up the river, ranging with his glass those miles of forbidding cliffs which he may already have begun to think he should one day have to climb. Some of Saunders' ships were in the Basin, between Orleans and Quebec, and frequently engaged with Montcalm's floating batteries; while in the mean time the roar of artillery from a dozen different quarters filled the simmering July days, and lit the short summer nights with fiery shapes, and drew in fitful floods the roving thunder-clouds that at this season of the year in North America are apt to lurk behind the serenest sky.
