At nine o'clock, Montcalm moved some distance to the front, and developed his line of battle; at the same time, M. de Bougainville, who was hastening down the left bank of the St. Lawrence, made a demonstration with some light cavalry upon Wolfe's extreme left. Townshend checked this movement by throwing the third battalion of the 60th into a line extending from the threatened flank to the post over the landing place.

Montcalm was already worsted as a general; it was, however, still left him to fight as a soldier. His order of battle was steadily and promptly arrayed. The center column, under Montcalm in person, consisted of the regiments of Bearne and Guienne, numbering together no more than 720 bayonets; with them were formed 1200 of the Canadian militia. On the right stood the regiments of La Sarre and Languedoc, and a battalion of the marine or colony troops, in all 1600 veterans; 400 of the militia, with one light field-piece, completed this wing. On the left, the Royal Roussillon and a battalion of the Marine mustered 1300 bayonets, while these disciplined regiments were supported by no less than 2300 of the Canadian levies. The total force, therefore, actually engaged, amounted to 7520 men, besides Indians; of these, however, not more than one half were regular troops: it was on them the brunt of the battle fell, and almost the whole loss. Wolfe's "field state" on the morning of the 13th of September, showed only 4828 men of all ranks from the generals downward, but of these every man was a trained soldier.

The French attacked. At about ten o'clock a crowd of Canadians and Indians emerged from the bush on the slope which falls toward the Valley of the St. Charles; as they advanced they opened fire upon the English pickets of the extreme left, and drove them into their supports. Under cover of the cloud of smoke which rose above the scene of this attack, the French veterans of the right wing passed swiftly round the left of Murray's Brigade, and turned his flank; then, throwing aside their irregulars, they fell upon Howe's Light Infantry. This gallant officer felt the importance of his post: the houses and the line of coppice which he occupied formed almost a right angle with the front of the British army, covering it in flank and rear. He was hardly pressed; his men fell fast under the overpowering fire of the French; but, in a few minutes, Townshend, with the 15th, came to his aid: soon afterward the two battalions of the 60th joined the line, and turned the tide of battle.

In the mean time swarms of skirmishers advanced against the right and center of the British army; their stinging fire immediately dislodged the few Light Infantry which Wolfe had posted in his front, and forced them back in confusion upon the main body. This first impression was not without danger: the troops who were in the rear, and could not see the real state of affairs, became alarmed at the somewhat retrograde movements in front. Wolfe perceived this: he hurried along the line, cheered the men by his voice and presence, and admonished them on no account to fire without orders. He succeeded: confidence was restored.

The spirited advance of the skirmishers was but the mask of a more formidable movement. The whole of the French center and left, with loud shouts and arms at the recover, now bore down to the attack. Their light troops then ceased firing and passed to the rear. As the view cleared, their long, unbroken lines were seen rapidly approaching Wolfe's position. When they reached within 150 yards, they advanced obliquely from the left of each formation, so that the lines assumed the appearance of columns, and chiefly threatened the British right. And now from flank to flank of the assailing battalions rolled a murderous and incessant fire. The 35th and the Grenadiers fell fast. Wolfe, at the head of the 28th, was struck in the wrist, but not disabled. Wrapping a handkerchief round the wound, he hastened from one rank to another, exhorting the men to be steady and to reserve their fire. No English soldier pulled a trigger: with matchless endurance they sustained the trial. Not a company wavered; their arms shouldered as if on parade, and motionless, save when they closed up the ghastly gaps, they waited the word of command.

When the head of the French attack had reached within forty yards, Wolfe gave the order to "fire." At once the long row of muskets was leveled, and a volley, distinct as a single shot, flashed from the British line. For a moment the advancing columns still pressed on, shivering like pennons in the fatal storm; but a few paces told how terrible had been the force of the long-suspended blow. Numbers of the French soldiers reeled and fell; some staggered on for a little, then dropped silently aside to die; others burst from the ranks shrieking in agony. The Brigadier de St. Ours was struck dead, and De Senezergues, the second in command, was left mortally wounded upon the field. When the breeze carried away the dense clouds of smoke, the assailing battalions stood reduced to mere groups among the bodies of the slain. Never before or since has a deadlier volley burst from British infantry.

Montcalm commanded the attack in person. Not fifteen minutes had elapsed since he had first moved on his line of battle, and already all was lost! The Canadian militia, with scarcely an exception, broke and fled. The right wing, which had recoiled before Townshend and Howe, was overpowered by a counter attack of the 58th and 78th; his veteran battalions of Bearne and Guienne were shattered before his eyes under the British fire; on the left the Royal Roussillon was shrunk to a mere skeleton, and, deserted by their Provincial allies, could hardly retain the semblance of a formation. But the gallant Frenchman, though ruined, was not dismayed; he rode through the broken ranks, cheered them with his voice, encouraged them by his dauntless bearing, and, aided by a small redoubt, even succeeded in once again presenting a front to his enemy.

Meanwhile Wolfe's troops had reloaded. He seized the opportunity of the hesitation in the hostile ranks, and ordered the whole British line to advance. At first they moved forward in majestic regularity, receiving and paying back with deadly interest the volleys of the French. But soon the ardor of the soldiers broke through the restraints of discipline: they increased their pace to a run, rushing over the dying and the dead, and sweeping the living enemy off their path. On the extreme right, the 35th, under the gallant Colonel Fletcher, carried all before them, and won the white plume which for half a century afterward they proudly bore.[184] Wolfe himself led the 28th and the diminished ranks of the Louisburg Grenadiers, who that day nobly redeemed their error at Montmorency. The 43d, as yet almost untouched, pressed on in admirable order, worthy of their after-fame in that noble Light Division which "never gave a foot of ground but by word of command." On the left, the 58th and 78th overcame a stubborn and bloody resistance; more than 100 of the Highlanders fell dead and wounded; the weak battalion by their side lost a fourth part of their strength in the brief struggle. Just now Wolfe was a second time wounded, in the body; but he dissembled his suffering, for his duty was not yet accomplished. Again a ball from the redoubt struck him on the breast:[185] he reeled on one side, but, at the moment, this was not generally observed. "Support me," said he to a Grenadier officer who was close at hand, "that my brave fellows may not see me fall." In a few seconds, however, he sank, and was borne a little to the rear. Colonel Carleton was desperately wounded in the head at a few paces from Wolfe; the aid-de-camp who hastened for Monckton, to call him to the command, found him also bleeding on the field, beside the 47th Regiment. At length Townshend, now the senior officer, was brought from the left flank to this bloody scene to lead the army.

The brief struggle fell heavily upon the British, but was ruinous to the French. They wavered under the carnage; the columns which death had disordered were soon broken and scattered. Montcalm, with a courage that rose above the wreck of hope, galloped through the groups of his stubborn veterans, who still made head against the advancing enemy, and strove to show a front of battle. His efforts were vain; the head of every formation was swept away before that terrible musketry; in a few minutes, the French gave way in all directions. Just then their gallant general fell with a mortal wound: from that time all was utter rout.

The English followed fiercely in the pursuit; the 47th and 58th, with fixed bayonets, pressed on close to the St. Louis and St. John's gates, till the first were checked by grape-shot from the ramparts, and the latter by the artillery of the hulks which were grounded in the river. But foremost in the advance, and most terrible to the flying enemy, were the 78th Highlanders; active and impetuous in their movements, and armed with the broadsword, they supplied in this case the want of cavalry to the British army. Numbers of the French fell beneath their vigorous blows;[186] others saved themselves by timely surrender, piteously craving mercy, and declaring that they had not been at Fort William Henry.[187] The remainder of Montcalm's right wing only found shelter beyond the bridge over the St. Charles. The survivors of the right and center soon placed the ramparts of Quebec between themselves and their pursuers.
