A history of the Peninsular War, Vol. 1, 1807-1809

When we turn to enumerate the forces opposed to the Emperor at Burgos, the disproportion between the two armies appears ludicrous. Down to November 6 the only Spanish troops in that ancient city consisted of two battalions, one from the reserves of the army of Galicia, the other from the army of Castile[452]. They numbered 1,600 men, and had four guns with them. If Bessières had attacked on the sixth, he would have found no more than this miserable detachment to oppose him. But on November 7 there arrived from Madrid the 1st Division of the army of Estremadura under the Conde de Belvedere, 4,000 foot and 400 horse with twelve guns. On the next day there came up the greater part of the 2nd Division of the same army, about 3,000 infantry and two regiments of hussars. On the tenth, therefore, when Soult attacked, Belvedere—who took the command as the senior general present—had about 8,600 bayonets, 1,100 sabres, and sixteen guns under his orders.

Down to November 2 the army of Estremadura had been commanded by Don Joseph Galluzzo, Captain-General of that province—the officer who had given so much trouble to Dalrymple by his refusal to desist from the futile siege of Elvas. He had been repeatedly ordered to bring his army up to Madrid, but did not arrive till the end of October. On the twenty-ninth of that month he marched for Burgos, his three divisions, 13,000 men in all, following each other at intervals of a day. But on November 2 he received orders to lay down his command and return to Aranjuez, to answer some charges brought against him by the Supreme Junta. No successor was nominated to replace him, and hence the conduct of the army fell into the hands of the Conde de Belvedere, the chief of the 1st Division, a rash and headstrong young aristocrat with no military experience whatever. His family influence had made him a general at an age when he might reasonably have expected to lead a company, and he found himself by chance the interim commander of an army: hence came the astonishing series of blunders that led to the combat of Gamonal.

Belvedere’s army was still incomplete, for his 3rd Division had only reached Lerma, thirty miles back on the Madrid road, when the French cavalry came forward and began to press in his outposts. Clearly a crisis was at hand, and the Count had to consider how he would face it. Isolated with 10,000 men on the edge of the great plain of Old Castile, and with an enemy of unknown strength in front of him, he should have been cautious. If he attempted a stand, he should at least have taken advantage of the ancient fortifications of Burgos and the broken ground near the city. But with the most cheerful disregard of common military precautions, the Count marched out of Burgos, advanced a few miles, and drew up his army across the high-road in front of the village of Gamonal. He was in an open plain, his right flank ill covered by the river Arlanzon, which was fordable in many places, his left completely ‘in the air,’ near the village of Vellimar. In front of the line was a large wood, which the road bisects: it gave the enemy every facility for masking his movements till the last moment. Belvedere had ranged his two Estremaduran batteries on the centre: he had six battalions in his first line, including two of the Royal Guards—both very weak[453]—with a cavalry regiment on each flank. His second line was formed of four battalions—two of them Galician: two more battalions, the four Galician guns, and his third cavalry regiment were coming up from the rear, and had not yet taken their post in the second line when the short and sudden battle was fought and lost[454].

Soult came on the scene during the hours of the morning, with the light-cavalry division of Lasalle deployed in his front. Then followed the dragoons of Milhaud, and three infantry divisions of the 2nd Corps—Mouton in front, then Merle, then Bonnet bringing up the rear. When he came upon the Spaniards, arrayed on either side of the road, the Marshal was able with a single glance to recognize the weakness of their numbers and their position. He did not hesitate for a moment, and rapidly formed his line of battle, under cover of the wood which lay between the two armies. Milhaud’s division of dragoons rode southward and formed up on the banks of the Arlanzon, facing the Spanish right: Lasalle’s four regiments of light cavalry composed the French centre: the twelve battalions of Mouton’s division deployed on the left, and advanced through the wood preceded by a crowd of tirailleurs. There was no need to wait for Merle and Bonnet, who were still some way to the rear.

The engagement opened by a discharge of the two Spanish batteries, directed at those of Mouton’s men who were advancing across the comparatively open ground on each side of the high-road. But they had hardly time to fire three or four salvos before the enemy was upon them. The seven regiments of cavalry which formed the left and centre of the French army had delivered a smashing charge at the infantry opposed to them in the plain. The regiment of Spanish hussars which covered their flank was swept away like chaff before the wind, and the unfortunate Estremaduran and Galician battalions had not even time to throw themselves into squares before this torrent of nearly 5,000 horsemen swept over them. They received the attack in line, with a wavering ill-directed fire which did not stop the enemy for a moment. Five battalions were ridden down in the twinkling of an eye, their colours were all taken, and half the men were hewn down or made prisoners[455]. The remnant fled in disorder towards Burgos. Then Milhaud’s dragoons continued the pursuit, while Lasalle’s chasseurs swerved inwards and fell upon the flank of the surviving half of Belvedere’s army. At the same moment the infantry of Mouton attacked them vigorously from the front. The inevitable result was the complete rout and dispersion of the whole: only the battalion of Walloon Guards succeeded in forming square and going off the field in some order. The rest broke their ranks and poured into Burgos, in a stream of fugitives similar to that which was already rushing through the streets from the other wing. The sixteen Spanish guns were all captured on the spot, those of the second line before they had been unlimbered or fired a single shot.

Belvedere, who was rash and incompetent but no coward, made two desperate attempts to rally his troops, one at the bridge of the Arlanzon, the other outside the city; but his men would not halt for a moment: their only concern was to get clear of the baggage-train which was blocking the road in the transpontine suburb. A little further on the fugitives met the belated battalions of Valencia and Zafra, which had been four or five miles from the field when the battle was lost. The Commander-in-chief tried to form them across the road, and to rally the broken troops upon them: but they cried ‘Treason,’ pretended that their cartridge-boxes were empty, broke their ranks, and headed the flight. Ere night they had reached Lerma, thirty miles to the rear, where the 3rd Division of Estremadura had just arrived.

Napoleon was probably using less than his customary exaggeration when he declared in his Bulletin that he had won the combat of Gamonal at the cost of fifteen killed and fifty wounded. It is at any rate unlikely that his total of casualties exceeded the figure of 200. The army of Estremadura on the other hand had suffered terribly: considering that its whole right wing had been ridden down by cavalry, and that the pursuit had been urged across an open plain for nine miles, it may well have lost the 2,500 killed and wounded and the 900 prisoners spoken of by the more moderate French narrators of the fight[456]. It is certain that it left behind twelve of the twenty-four regimental standards which it carried to the field, and every one of its guns[457].

The French army celebrated its not very glorious victory in the usual fashion by sacking Burgos with every attendant circumstances of misconduct. They were so much out of hand that the house next to that in which the Emperor had taken up his quarters for the night was pillaged and set on fire, so that he had to shift hastily into another street[458].

The night of the tenth was devoted to plunder, but on the following morning Bonaparte resumed without delay the execution of his great plan, and hurried out to the south the heavy masses of cavalry which were to sweep the plains of Old Castile. Lasalle’s division pushed on to Lerma, from which the shattered remnants of the army of Belvedere hastily retired. Milhaud’s dragoons were directed on Palencia, Franceschi’s light cavalry more to the west, along the banks of the Urbel and the Odra. Nowhere, save at Lerma, was a single Spanish soldier seen, but it is said that some of Milhaud’s flying parties obtained vague information of the advance of Sir John Moore’s English army beyond the frontier of Portugal. His vanguard was reported to be at Toro, an utter mistake, for the expeditionary force had not really passed Salamanca on the day when the rumour was transmitted to the Emperor[459]. There is no sign in his dispatches of any serious expectation of a possible British diversion.

On the same day on which the cavalry poured down into the plains of Castile, the Emperor began also to execute the great flanking movements which were to circumvent the armies of Blake and Castaños and to drive the one into the Bay of Biscay and the other against the Pyrenees. On the afternoon of the eleventh Soult, with the three divisions of Mouton, Merle, and Bonnet, and Debelle’s cavalry brigade[460], was directed to make forced marches upon Reynosa, by the hilly road that passes by Urbel and Olleros[461]. It was hoped that he might reach Reynosa before Blake, whose retreat towards the west was being closely pressed by Victor and Lefebvre. If he failed to catch the army of Galicia, the Marshal was to push on across the mountains, and occupy the important harbour-town of Santander, where it was known that British stores had been landed in great quantities. Milhaud was to co-operate in this movement by sending from Palencia one of his brigades of dragoons, to cut the road from Reynosa to Saldaña, by which the Emperor considered it likely that Blake would send off his heavy baggage and guns when he heard of Soult’s approach[462]. Two days after dispatching Soult to the north-west, the Emperor gave orders for the other great turning movement, which was destined to cut off the army of Castaños. On the thirteenth Marshal Ney, with one division of his own corps (that of Marchand) and with the four regiments of Dessolles from the central reserve, together with the light cavalry of Beaumont, had marched from Burgos, in the wake of Lasalle’s advance. On the sixteenth he reached Aranda de Duero, and, having halted there for two days, was then directed to turn off from the high-road to Madrid, and march by Osma and Soria so as to fall upon the rear of Castaños, who was still reported to be in the neighbourhood of Tudela[463]. If he could succeed in placing himself at Tarazona before the enemy moved, the Emperor considered that the fate of the Spanish ‘Army of the Centre’ was sealed.
