It is said that Junot and Reynier were in favour of trying the frontal attack which Masséna had dictated, as was also Laszowski, the Polish general who commanded the engineers of the army. Fririon, the chief of the staff, and Eblé, commanding the artillery, spoke against the policy of ‘taking the bull by the horns.’ Masséna, according to Fririon, turned on the doubters with the words ‘You come from the old Army of the Rhine, you like manœuvring; but it is the first time that Wellington seems ready to give battle, and I want to profit by the opportunity[423].’ Ney, too, as we read with some surprise, is said to have given the opinion that it would have been feasible to assault the heights yesterday, but that now, when Wellington had been given time to bring up his reserves and settle his army down into the most advantageous position, the policy of taking the offensive had become doubtful. He therefore advised that the army should turn aside and make a stroke at Oporto, which would be found unprotected save by militia. Masséna, according to his official biographer, announced ‘that the Emperor had ordered him to march on Lisbon, not on Oporto. This was entirely correct: the capture of Lisbon would end the whole war, that of Oporto would prolong it, and bring no decisive result. Moreover, it was quite uncertain whether Wellington would not be able to prevent such a move. He has troops échelloned as far as the Vouga, and he could get to Oporto in three marches, because he possesses the Oporto-Coimbra chaussée, while the French army, moving by worse roads, would require five marches to reach it.’ It is suggested that Ney’s policy was really to goad his superior into making the frontal attack at Bussaco, by feigning to believe it dangerous and to counsel its abandonment. For he thought that Masséna would do precisely the opposite of what he was advised, out of his personal dislike for himself, and general distaste for having counsel thrust upon him. If this was so, the Duke of Elchingen carried his point—to the entire discomfiture both of himself and his commander-in-chief[424].

On the 26th, after Masséna had retired to his head quarters at Mortagoa, there was a little skirmishing on the English right-centre, where Reynier’s advanced guard drove the light company of the 88th off some knolls at the foot of the heights, opposite San Antonio de Cantaro. Much about the same time there was some bickering on Ney’s front: the pickets of Pack’s 4th Caçadores and Craufurd’s 95th were attacked, but held their ground. The contest was never very serious and the fire died down at dusk. That evening the British army slept in order of battle, ‘each man with his firelock in his grasp at his post. There were no fires, and the death-like stillness that reigned throughout the line was only interrupted by the occasional challenge of an advanced sentry, or a random shot fired at some imaginary foe.’ Below and in front, all the low hills behind Moura and San Antonio were bright with the bivouac fires of the French, of which three great masses could be distinguished, marking the position of the 2nd, 6th, and 8th Corps[425].

The dawn of the 27th was somewhat misty, but as soon as the light was strong enough Reynier commenced his attack. He had chosen for his objective, as was natural, the lowest point of the ridge opposite him, the dip where the country-road from San Antonio de Cantaro crosses the Serra. His two divisions, according to order, were drawn up in two heavy columns preceded by a dense swarm of tirailleurs. Heudelet’s division on the left was across the high-road, with the 31st Léger in front, then the two regiments of Foy’s brigade, the 70th and 17th Léger, with the 47th in reserve. The whole made 15 battalions, or 8,000 men. Merle’s division had the right, and was to attack north of the road: of its eleven battalions, making 6,500 men, the 36th of the Line led, the 2nd Léger followed, the 4th Léger brought up the rear. All the battalions were in serried column with a front of one company only, and in each regiment the three, or four, battalions were originally drawn up one behind the other. But the involuntary swerving of the attack soon turned the two divisions into an irregular échelon of battalion-columns, the right in every case leading. And the roughness of the hillside soon broke the ordered ranks of each column into a great clump of men, so that to the British defenders of the ridge the assault seemed to be delivered by a string of small crowds crossing the hillside diagonally. It is curious that Reynier placed no troops to his left of the road; a study of his orders (as of those of Masséna[426]) leads to a suspicion that they had failed to discover Leith’s division, and still more Hill’s, and imagined that the road was on the extreme right, not in the right-centre, of the British position. Otherwise Reynier would have taken some precaution to guard himself from a flank attack from Leith, to which he was deliberately exposing his left column.

There were, as has already been pointed out, several gaps in the nine-mile British line. One was between the 8th regiment of Portuguese, on Leith’s extreme left, and the rest of the 5th Division. Another was between Picton’s troops at the pass of San Antonio and his left wing—the 88th and Lightburne’s brigade. Between the 45th and the 88th there was three-quarters of a mile of unoccupied ground. The first gap led to no danger, the second caused for a moment a serious crisis. Such was indeed almost bound to occur when a line so long was held by such a small army. But this morning there arose the special danger that fog hid the first movements of the enemy from the eye, if not from the ear.

Merle’s division seems to have been the first of Reynier’s two columns to move: at dawn, with the mist lying thick on the hillside, it began to move up the steep slope some three-quarters of a mile to the right of the San Antonio-Palheiros road. Here its tirailleurs came in contact with the light companies of the 74th, 88th, and 45th regiments, which were strung out along the front, and soon began to push this thin line up hill. For some reason undetermined—a trick of the mist, or a bend of the hillside—the three French regiments all headed somewhat to their left, so as to pass across the front of the 88th, and to direct their advance precisely to the unoccupied piece of crest between that regiment and the troops placed immediately above the pass of San Antonio. Their progress was slow: the tirailleurs left far behind them the eleven battalion-columns, which were trampling through the dense matted heather which here covers the hillside. Hearing the bicker of the skirmishing far to his left, Picton took the alarm, and though he could see nothing in the fog, detached first a wing of the 45th under Major Gwynne, and then the two battalions of the 8th Portuguese, to fill the unoccupied space which intervened between him and the 88th. If he had suspected the strength of the column that was aiming at it he would have sent more. But he was already distracted by the frontal attack of Heudelet’s vanguard along the high-road. A column of four battalions—the 31st Léger—was pushing up the road, and driving in the skirmishers of Champlemond’s Portuguese brigade. Just at this moment the mist began to lift, and Arentschildt’s guns opened on the broad mass, and began to plough long lanes through it. It still advanced, but was soon brought to a standstill by the fire of the British 74th and Portuguese 21st, which were drawn up in line to right and left, a little below the guns. The 31st Léger tried to deploy, but with small success, each section being swept away by the converging fire of the Anglo-Portuguese musketry, as it strove to file out of the disordered mass. Nevertheless, the French regiment gallantly held its ground for some time, shifting gradually towards its right to avoid the fire of the guns, and gaining a little of the hillside in that direction with its first battalion, while the other three were tending to edge away from the road, and to break up into a shapeless crowd[427].

Picton soon saw that there was no danger here, handed over the command at the Pass of San Antonio to Mackinnon, and started off towards his left, where the firing was growing heavier every minute, and the vast column of Merle’s division, climbing the hillside diagonally, had become visible through the mist.

It was fortunate that the attack of Merle was made very slow by the steepness of the hillside and the heather that clung about the soldiers’ stumbling feet. For the leading regiment reached the crest before there were any British troops yet established on the point at which it aimed. It was lurching over the sky-line on to the little plateau above, just as the defenders arrived—the 88th descending from the British left, the wing of the 45th and the two battalions of the 8th Portuguese coming along the hill-road from the right. If the French had been granted ten minutes to rest from the fatigue of their long climb, and to recover their order, they might have broken the British line. But Wallace, the commander of the 88th, was one of Wellington’s best colonels, the very man for the emergency. Seeing that the French must be charged at once, ere they had time to make a front, he threw out three of his companies as skirmishers to cover his flanks, called to the wing of the 45th to fall in on his right, and charged diagonally across the little plateau on to the flank of the great disordered mass before him. At the same moment the 8th Portuguese, a little further along the hilltop, deployed and opened a rolling fire against the front of the enemy, while Wellington himself, who had been called down from his post of observation on the Convent height by the noise of the fighting, came up with two of Thompson’s guns, and turned their fire upon the flank and rear of the climbing mass, which was still surging up the hillside. Apparently at the same instant the light companies of the 45th and 88th, which had been engaged in the earlier skirmishing with the French tirailleurs, and had been driven far away to their right, were rallied by Picton in person, and brought up along the plateau, to the right of the 8th Portuguese. They drew up only sixty yards from the flank of the leading French regiment, and opened a rolling fire upon it.

At any other juncture and on any other ground, four battalions would have been helpless against eleven. But Wallace had caught the psychological moment: the French 36th, dead beat from its climb, and in hopeless disorder, was violently charged in flank by the Connaught Rangers and the wing of the 45th, while it was just gathering itself up to run in upon the Portuguese battalions that lay in its front. The French had no time to realize their position, or to mark the smallness of the force opposed to them, when the blow fell. The four battalions of the 36th were rolled down hill and to their left by the blasting fire of Wallace’s little force, followed by a desperate bayonet charge. They were thrust sideways against the 2nd Léger, which was just reaching the sky-line on their left, and was beginning to struggle in among some rocks which here crown the crest of the heights. Then the whole mass gave way, trampled down the 4th Léger in their rear, and rushed down the slope. ‘All was confusion and uproar, smoke, fire, and bullets, French officers and soldiers, drummers and drums, knocked down in every direction; British, French, and Portuguese mixed together; while in the midst of all was to be seen Wallace fighting like his ancestor of old, and still calling to his soldiers to “press forward.” He never slackened his fire while a Frenchman was within his reach, and followed them down to the edge of the hill, where he formed his men in line waiting for any order that he might receive, or any fresh body that might attack him[428].’ This was certainly one of the most timely and gallant strokes made by a regimental commander during the war, and the glory was all Wallace’s own, as Picton very handsomely owned. ‘The Colonel of the 88th and Major Gwynne of the 45th are entitled to the whole of the credit,’ he wrote to Wellington, ‘and I can claim no merit whatever in the executive part of that brilliant exploit, which your Lordship has so highly and so justly extolled[429].’
