During the year 1811 the French arms made considerable progress on the east side of Spain: this did not however give them any real additional advantage as against Wellington. They had more fortresses to garrison, more territory to occupy, and the Spanish armies went on causing much the same trouble to them as before. Moreover Napoleon's system of giving the various generals independent spheres of action, with no common control except his own, worked in Wellington's favour. If he made a threatening movement against Marmont, who commanded what was called the army of Portugal, occupying the basin of the upper Douro, or against Soult in Andalusia, neither marshal could order the other to assist him by a diversion. There was an obvious difference between combined action ordered by a chief who controlled the whole, and co-operation arranged between equals who had each his own separate ends in view. Napoleon should either have come to Spain in person—he was too far off in point of time to direct from Paris—or have given one marshal[71] command throughout the country. When towards the end of 1811 Wellington judged that the time was come for operations no longer merely defensive in purpose, he formed his plans to take advantage of this want of union among his enemies.

It has been pointed out that the ways into Spain from Portugal are practically three: but the central one by the valley of the Tagus being ill suited for the movements of armies, there are but two really advantageous. That by the basin of the Douro is guarded at the frontier by two fortresses, Almeida and Ciudad Rodrigo; that by the Guadiana is guarded by Elvas and Badajos. Without possession of the pair of fortresses commanding one route or the other, invasion is scarcely feasible: with both pairs in his hands Wellington could choose, and he already held both Almeida and Elvas. Accordingly he resolved during the winter season, when the French would have serious difficulty in moving, to besiege first one and then the other of the Spanish border fortresses. He began with Ciudad Rodrigo, partly because it was the easier task to prepare for, as he had a battering-train in Almeida of which the French knew nothing (the guns were supposed to have been brought there to arm the fortress), partly because he then purposed to move against Soult if he succeeded in capturing Badajos. The preparations for the siege were very quietly made in Almeida, and on January 8, 1812, the first British troops appeared before Ciudad Rodrigo. That very evening a detached fort to the north of the town was suddenly stormed, which enabled the trenches to be begun much nearer to the walls than could otherwise have been done. Wellington had calculated that he should require twenty-four days, but the uncertainties were great, for besides the prospect of Marmont coming to its relief, there was always the risk that heavy rain might raise the river Agueda in flood prematurely, which would have stopped the siege by intercepting communication across it. On the 19th the walls were sufficiently breached to make storming them possible, though according to the ordinary rules of siege warfare much remained to be done before an assault was made. Wellington however knew as well how and when to make a sacrifice in order to attain an adequate object, as how to spare his men: he issued orders for the assault to take place that night, ending with the emphatic words: "Ciudad Rodrigo must be stormed this evening." There were two breaches near together on the north face of the fortress, both of which were directly assailed, besides minor attacks on other points. The fighting at the main breach was desperate, for the French were well prepared: possibly the attack there might not have succeeded, but the conflict was ended by the success of the light division at the smaller breach.

"The bottom of the ditch was dark and intricate, and the forlorn hope took too much to their left; but the storming party went straight to the breach, which was so contracted that a gun placed lengthwise across the top nearly blocked up the opening. Here the forlorn hope rejoined the stormers, but when two-thirds of the ascent were gained, the leading men, crushed together by the narrowness of the place, staggered under the weight of the enemy's fire; and such is the instinct of self-defence, that although no man had been allowed to load, every musket in the crowd was snapped. The commander, Major Napier, was at this moment stricken to the earth by a grape-shot which shattered his arm, but he called on his men to trust to their bayonets, and all the officers simultaneously sprang to the front, when the charge was renewed with a furious shout, and the entrance was gained. The supporting regiments, coming up in sections abreast, then reached the rampart, the 52nd wheeled to the left, the 43rd to the right, and the place was won."

The loss of life was great, the English having nearly as many killed and wounded as the whole garrison: General Craufurd, the brilliant commander of the light division, was killed. The officer who led the forlorn hope at the lesser breach was the man to whom the governor of Ciudad Rodrigo surrendered, an incident probably unique in the annals of siege warfare. The advantage gained, which was attainable in no other way, was well worth the cost. It was henceforth impossible for Marmont seriously to invade the north-east of Portugal: and the capture in Ciudad Rodrigo of Marmont's battering-train made it certain that he would not even try.

Wellington's calculations were nicely adapted to the season of the year, as well as to the other conditions. He felt sure that in the rains of February and March, with all the rivers in flood, Marmont could not practically move at all, and that therefore he might be watched by a very small force, while he himself went south to continue the scheme he had formed. Elvas served, as Almeida had done, for a convenient place to make siege preparations within a short distance of Badajos, and on March 16 the famous siege was begun, ten days at least later than Wellington had intended, through the default of the Portuguese in providing transport. This was a much more serious task than the capture of Ciudad Rodrigo, the garrison being three times as large, the defences stronger, and the governor, Phillipon, a man of great energy and fertility of resource. Two of Soult's divisions were near at hand; but Wellington, having decided that he might practically ignore Marmont, had plenty of men to spare for covering the siege, at least until Soult should approach with his whole army. He had also arranged, so far as it was possible to arrange anything with the Spanish armies, that one of them should be in a position to march on Seville if Soult denuded Andalusia too completely of troops.

Badajos is situated on the south bank of the Guadiana, with a strong fort on the north bank. The castle was at the north-east corner of the town, close to the river: along the east face a rivulet flowing into the Guadiana had been artificially extended into a complete defence for nearly half the length. A small outwork covered the northern end of this piece of water, and outside its southern end, on an isolated hill, stood a work called the Picurina. The plan was to breach, at the south-eastern corner of the town, the two great bastions known as the Trinidad and the Sta. Maria, and the curtain uniting them. In order that this might be done effectually, the Picurina must first be taken, and after the siege works had made sufficient progress, on the night of March 25, this work was stormed, and batteries constructed on its ruins. As the siege progressed, Soult drew near, and arrangements were actually made for leaving two divisions to hold the trenches, and marching with the rest of the army to give him battle. On April 6 however the breaches were reported practicable, Soult being still some way off; Badajos could therefore be assaulted with adequate force.

Three separate attacks were arranged, besides minor ones merely to distract attention, all to begin at ten p.m. The third division, Picton's, was to cross the rivulet on the east side and scale the castle walls; the fifth was to attack the west face of the town; to the fourth and light divisions was assigned the frightful task of storming the breaches. A fireball thrown by the French however disclosed to them the third division ready formed and awaiting the signal: the assault was consequently begun half-an-hour sooner on the east and south-east, and the perfect concert with the other distant attacks was lost. After one failure, the third division succeeded in scaling the castle and driving the French out of it, but were unable for some time to advance any further. The assault on the breaches was one of the most terrible scenes on record. Nothing could exceed the determination of the stormers, but the French had made preparations for defence which were simply insuperable.

"Now a multitude bounded up the great breach as if driven by a whirlwind, but across the top glittered a range of sword-blades, sharp-pointed, keen-edged on both sides, and firmly fixed in ponderous beams, which were chained together and set deep in the ruins; and for ten feet in front, the ascent was covered with loose planks, studded with sharp iron points, on which the feet of the foremost being set the planks moved, and the unhappy soldiers, falling forward on the spikes, rolled down upon the ranks behind. Then the Frenchmen, shouting at the success of their stratagem, and leaping forward, plied their shot with terrible rapidity, for every man had several muskets; and each musket in addition to its ordinary charge contained a small cylinder of wood stuck full of leaden slugs which scattered like hail when they were discharged.

"Again the assailants rushed up the breaches, and again the sword-blades, immovable and impassable, stopped their charge, and the hissing shells and thundering powder-barrels exploded unceasingly. Hundreds of men had fallen, and hundreds more were dropping, but still the heroic officers called aloud for new trials, and sometimes followed by many, sometimes by a few, ascended the ruins; and so furious were the men themselves, that in one of these charges, the rear strove to push the foremost on to the sword-blades, willing even to make a bridge of their writhing bodies, but the others frustrated the attempt by dropping down; and men fell so fast from the shot, that it was hard to know who went down voluntarily, who were stricken, and many stooped unhurt that never rose again. Vain also would it have been to break through the sword-blades, for the trench and parapet behind the breach were finished, and the assailants, crowded into even a narrower space than the ditch was, would still have been separated from their enemies, and the slaughter would have continued.

"Two hours spent in these vain efforts convinced the soldiers that the breach of the Trinidad was impregnable; and as the opening in the curtain, although less strong, was retired, and the approach to it impeded by deep holes, and cuts made in the ditch, the troops did not much notice it after the partial failure of one attack which had been made early. Gathering in dark groups and leaning on their muskets, they looked up with sullen desperation at the Trinidad, while the enemy stepping out on the ramparts, and aiming their shots by the light of the fire-balls which they threw over, asked, as their victims fell, 'Why they did not come into Badajos?'"
