A history of the Peninsular War, Vol. 4, Dec. 1810-Dec. 1811

The loss of the British on this occasion, all in the 13th Light Dragoons[329], was 10 killed, 3 officers and 24 men wounded, and 22 prisoners; among the Portuguese 1st and 7th cavalry an officer and 13 men killed, 40 wounded, and 55 prisoners—a total of over 150. The French suffered more—the 26th Dragoons alone had 8 officers[330] and over 100 men killed, wounded, and taken, the train and artillery had been dreadfully cut up at the capture of the convoy, and the infantry had lost 3 officers and many men by the fire of Cleeves’s guns. The total casualties were over 200[331]. But the moral effect of a combat is not judged by a mere comparison of losses, and the British officers were much disappointed. Beresford and his friends held that Long had by mismanagement wasted 150 precious cavalrymen—Long declared that if Beresford had not taken the command out of his hands he would have captured the whole French column. This last claim was absolutely unreasonable: it is far more likely that he would merely have caused severe loss to the two heavy dragoon regiments by persisting. The Marshal and the General were on bad terms from this moment onward, and the former took the next opportunity given him to remove the latter from the chief command of the allied cavalry. The most curious comment on the combat of Campo Mayor is Napier’s statement that ‘the 13th Light Dragoons were severely reprimanded for pursuing so eagerly. But the unsparing admiration of the whole army consoled them!’ Pursuing eagerly is a mild expression for riding seven miles off the battlefield, and on to the glacis of a hostile fortress. Wellington’s comment was that ‘the undisciplined ardour of the 13th Dragoons and the 7th regiment of Portuguese cavalry is not of the description of the determined bravery of soldiers confident in their discipline and their officers. Their conduct was that of a rabble galloping as fast as their horses could carry them, after an enemy to whom they could do no further mischief when they were broken: the pursuit was continued for an unlimited distance, and sacrificed substantial advantages, and all the objects of the operation, by want of discipline[332].’ A similar reproof was published in a General Order, to be read to the cavalry.

The only really satisfactory result of the combat of Campo Mayor was that Beresford recovered the town intact, with some guns which had not yet been sent off to Badajoz, and a considerable amount of stores, including 8,000 rations of biscuit. The place was at once re-garrisoned with the Faro regiment of militia from Elvas, who rapidly repaired the breach. It was tenable again in a few days.

On the 26th Beresford discovered that the French had withdrawn entirely beyond the Guadiana, keeping nothing north of it save the bridge-head and Fort San Cristobal at Badajoz. All accounts agreed that after deducting the garrison of that place Mortier could not have more than 8,000, or at the most 10,000, men available for the field, so that there was no reason why Wellington’s orders to thrust him out of Estremadura, and besiege Badajoz, should not be carried out. It was particularly directed in those orders that the expeditionary force should cross the Guadiana at Jerumenha, and make a bridge at that place, only a few miles from the strong fortress of Elvas, the base of its line of communications[333]. Accordingly the 2nd Division and Hamilton’s Portuguese marched to Elvas on the 26th, leaving Cole and the 4th Division (still much fatigued by their long march) for a day at Campo Mayor. There can be no doubt that if Beresford had been able to cross at Jerumenha on the 27th or 28th he would have compelled the French to retire southward at once, and might have invested Badajoz, then not yet fully repaired, as soon as he chose. But a most tiresome series of hindrances, for which it seems unjust to blame the Anglo-Portuguese commander, now began to crop up. The first and most fatal was that the stock of Spanish pontoon boats which, as he had been told by Wellington, would be found at Elvas or Jerumenha, was not forthcoming. Only five were discovered: two complete bridge-equipages had been kept by Imaz at Badajoz, and were now in the hands of the French. But twenty large pontoons, as the engineers declared, was the least number which would suffice to bridge the Guadiana. An attempt was made to seek for river-craft to eke out the pontoons. But by Wellington’s orders all the boats on the river for many miles had been destroyed, when Soult entered Estremadura in January. Some Portuguese pontoons were ordered from Lisbon, but it would be a week or so before they could be carted across the Alemtejo. Meanwhile Captain Squire, the engineer charged with the bridge-building, offered to lay trestles across the shallower part of the bed of the Guadiana on either bank, and to moor the five pontoons in the deep channel in the middle to join them. To this Beresford assented, and the bridge-place was selected on the 30th: Squire promised that the whole should be completed on the 3rd of April; he could not finish it earlier, as the wood for the trestles had to be found, cut down, and shaped ab initio.

The delay of a week thus caused was of the less importance, however, because of another contretemps. There were no stores ready to feed the army when it should cross the Guadiana. The 200,000 rations at Estremos which Wellington (as it will be remembered) had promised to Beresford, were found to have been entirely consumed by the wreck of Mendizabal’s army, who had been lying there for the last three weeks. There was nothing to lade upon the mules and carts of the expeditionary force; the troops were in great difficulties from day to day, ate the 8,000 rations at Campo Mayor, and were finally forced to indent upon the stores of the garrison of Elvas, which ought to have been sacred to the defence of the town.

Lastly, and this was perhaps the most important of all, the shoes of the 4th Division, which had marched continuously from the 6th to the 22nd of March, first from the Lines to Espinhal, and then from Espinhal to Portalegre, were completely worn out. Cole protested against the division being moved till it was reshod. No footgear could be found at Elvas, and though an immediate requisition was sent to Lisbon, the convoy bringing the shoes would obviously take a week or so to get up[334]. From the 26th of March to the 3rd of April Beresford was perforce immovable. This loss of eight days was apparently the reason why Badajoz did not fall into his hands a little later, for the fortifications, which were still in a dangerous state of disrepair on the 25th, were practically tenable by the second week in April. The stores in the fortress were a less important matter. Imaz when he surrendered had over a month’s rations for 9,000 men, which, even when a certain amount had been consumed by Soult’s field army, left a nucleus sufficient to keep the garrison of 3,000 men placed in the town by Mortier out of need for many weeks. In addition, cattle had been requisitioned all over Estremadura. The small movable force of 8,000 men which was available for observing Beresford, was now living entirely on the country-side, in order to spare the stores of Badajoz.

Beresford’s delay in crossing the Guadiana, therefore, was unfortunate, but apparently inevitable, and there seems no reason to blame him for it. On April 3rd the engineers reported that the bridge at Jerumenha would be ready that evening, and the three divisions concentrated on the left bank: the water was low, and a difficult ford for cavalry had been found above the bridge, by which a squadron of dragoons passed, and established a chain of pickets on the Spanish side. No French were seen abroad, though it was discovered that they still had a garrison in Olivenza, only six miles away. It is difficult to make out why no attempt was made to obstruct the building of Beresford’s bridge—the enemy had five regiments of cavalry in Estremadura, and 6,000 infantry of Girard’s division were available for field service. Even a small detachment with some guns would have made it impossible for the British engineers to complete their work. But the Allies found a great advantage in the fact that Mortier had just received orders to return to Paris, and had on March 26th handed over the command of all the troops on the Guadiana to Latour-Maubourg, who was a good divisional general on the battlefield, but a very indifferent strategist. All his manœuvres during the following month were weak and confused. How it came that from the 30th of March to the 7th of April no French cavalry were seen opposite Jerumenha, much less any serious force sent to disturb the bridge-building, it is impossible to conceive. By all accounts the horsemen who should have been in front of Olivenza were at this time mainly employed in scouring the villages of Central Estremadura for cattle and corn, and escorting what they could seize into Badajoz and the camp of Girard’s division.

On the morning of March 4th, when the allied troops should have crossed the Guadiana, Beresford was brought the untoward news that the river had risen three feet in the night, had swept away the trestles, and forced the engineers to draw back the five pontoon boats in the central stream to the Portuguese bank. The squadron beyond the river was cut off from the army, and communication with it was only restored during the day, by rigging up a flying bridge composed of a raft and a rope. The cavalry ford above the destroyed bridge was of course impassable. Throughout the 4th and 5th the water continued to rise, from storms higher up the river apparently, for there was no rain at Jerumenha.

The position was exasperating to the highest degree. ‘Establishing a permanent bridge is out of the question,’ writes D’Urban, the chief of the staff, in his journal. ‘The means are anything but secure either for passing the army (tedious beyond measure, too, no doubt), or for establishing a communication afterwards for supplies and other purposes. Nevertheless the general state of things, and above all Lord Wellington’s reiterated orders received this morning, render it necessary to pass[335].’ The engineers, put upon their mettle, finally made the five Spanish pontoon boats into two flying bridges worked by ropes. On these a battalion of infantry was passed across the river, and stockaded itself on the other side. Later in the day (April 5) some small tin pontoons arrived from Lisbon, and out of these, helped by all the wine-casks of the neighbouring villages, collected in haste, a floating bridge was constructed, ‘not very substantial, but, upon trial, found capable of admitting infantry to pass in file[336].’ It was not ready till noon on the 6th, but by the two flying bridges the whole 2nd Division and three squadrons of cavalry were passed on the night of the 5th-6th. What might have happened it Latour-Maubourg had concentrated at Olivenza, and fallen on the first two or three battalions that crossed with a force of all arms, we had better not inquire[337]. A disaster on a small scale might very possibly have occurred. But not a Frenchman was seen.

During the 6th Hamilton’s Portuguese passed with infinite slowness on the flying bridges, and the cask and pontoon bridge being at last completed, Cole’s 4th Division and Long’s cavalry began to file over it at dusk, an operation so tedious that the last of them were not over till the following dawn. Ere they were all across a ‘regrettable incident’ occurred: the advanced cavalry pickets were formed on the night of the 6th-7th by Major Morris’s squadron of the 13th Light Dragoons. Owing to bad staff work in the placing of them (as D’Urban and General Long both assert), the main guard of this squadron was surprised by French cavalry in the dusk of the morning, and captured almost entire, two officers and fifty men being taken. The assailants found that they had run into the camp of a whole army, and promptly retired before they could be touched.

At last Latour-Maubourg had given signs of life; this reconnaissance had been conducted by a flying column of two cavalry regiments and four battalions, under General Veilland, sent out to Olivenza from the camp of Girard’s division, with the very tardy purpose of hindering Beresford’s passage. Veilland reported to his chief that the enemy was across in such strength that he could do nothing. The appearance of 20,000 men on the Spanish bank of the Guadiana, so far to the south of Badajoz, placed Latour-Maubourg in a very delicate position: if he stayed twenty-four hours longer in his present camp close to Badajoz, he lost his communications with Andalusia, and might be pushed eastward up the Guadiana, out of touch with Soult, and having no retreat save towards the distant Army of the Centre. It was even possible that a rapid advance of the Allies might drive him into Badajoz, the last thing that he would desire. Accordingly he concentrated at Albuera, twelve miles south of that fortress, as a preliminary move, and prepared to fall back from thence by the great southern chaussée, towards Llerena and the Sierra Morena, where he would preserve, and shorten, his line of communication with Soult. Phillipon was left with 3,000 men in Badajoz, which was now quite beyond danger from a coup de main, and able to take care of itself for some weeks, till reinforcements should come up from Andalusia for its relief. With great unwisdom Latour-Maubourg left Olivenza garrisoned also; it was, as had been shown in January, contemptible as a fortress, even when held by a large force, and the French general placed in it only a single weak battalion of under 400 men. There were still on the walls the few guns that had been taken from the Spaniards—no more than fifteen were mounted, and several of these only on makeshift carriages. Why Latour-Maubourg chose to sacrifice a battalion it is hard to see; Napoleon wrote to Soult a month later to condemn the policy of small garrisons in the strongest terms[338]. At the best Olivenza, when so weakly held, could not hold out for more than a few days, and if Beresford had tried to rush it by escalade, when first he arrived before its walls, he must undoubtedly have succeeded, for 400 men cannot defend three miles of enceinte against a serious assault. There were some magazines in the place, and a small hospital of sick, who could not be removed[339]. But it was obviously absurd to throw away a battalion of sound men to keep them from capture for a few days. It has been suggested that Latour-Maubourg merely wanted to gain time[340]; but the time gained was trifling—Olivenza only held out five days—and might have fallen much sooner.
