Exhausted
The nature of the campaign was a divergence from what we had come to expect. There was no experience upon which to plan a campaign. . . . The armed and disciplined enemy army sustained with steady constancy a national struggle against French armies on fields of battle and especially in besieged towns. But the greater part of the population, sometimes without any distinction of age or sex, embarked in that active and obstinate species of contest which brought enemies upon us in all directions and exhausted us far more than regular engagements.
- Marshal Louis-Gabriel Suchet, in his memoirs on the war in Spain
It was a fateful decision when this nation was chosen as the destination of the next campaign. It was a hostile territory to any conventional army, a barren landscape with scattered forests, and occasionally rough and hilly terrain. It was unsuitable for large strategic manoeuvres, and the supply lines were stretched far over land. This war was nothing like the other wars of this, the strongest army in the world. Suddenly the army was given the task of handling a hostile population, fighting guerrillas roaming the countryside, fighting gangs of robbers attacking supply lines, and fighting conventional troops either supporting the guerrillas or sometimes even appearing for full-scale battle.
Today, this is not an unusual situation for a large conventional force to find itself involved in. Neither is it a new one, it could be seen when the Romans attacked Germany, when the French attacked Tyrol and Calabria, when the Germans fought partisans in Russia, when the Americans intervened in Vietnam, the Russians in Afghanistan, and the list could go on. So far, we do not seem to have found any solution to this problem, and to this date, a guerrilla war in a hostile remote country is the terror of many or most conventional armed forces. To find another, and perhaps more interesting example of this warfare, and more significantly of how to fight it, we should look at the origin of the word guerrilla. It is Spanish and literally means little war.
The word originated in the French wars on the Iberian peninsula from October 1807 till the end of Napoleon after The Russian Campaign in 1814. These wars were to be known as some of the most brutal and bitter fighting of the Napoleonic Wars with French forces fighting far away from home in a country nothing like the fertile lands of Germany and Italy they were used to.
Napoleon used to boast that 20,000 troops could find food for themselves in a desert, and it remained a doctrine of the French and many other armies of the Napoleonic Wars that armies should support themselves through confiscating, foraging, in the territories they fought. This had worked well for the French troops when fighting in the fertile Po valley or the rich fields of southern Germany but the situation was entirely different in Spain. Spain consisted of large hilly plateaus, sunny desert-like plains, and mountains, as unwelcoming as possible. Furthermore, the practice of foraging in enemy territory did, as could be expected, spark hostility among the natives. In Spain, where the locals were already living in poverty and in conditions close to starvation, this became a huge problem.
The War
By 1807, Napoleon dominated the continent. The Austrians had been defeated at Ulm and Austerlitz in 1805 in two of the most stunning victories of military history. In the ensuing war with Prussia, Napoleon and his perhaps most able marshal, Davout, had finished off the Prussians at Jena and Auerstedt in 1806. After defeating the Russians in Eastern Prussia at Friedland in 1807, Napoleon stood left uncontested on the continent. But one foe remained. This was the British.
The British had since the start of the revolutionary wars been the most stubborn and tenacious enemy. The French had intended an invasion of Ireland as early as 1796, and Napoleon had contemplated invading the British mainland many times until the disaster at Trafalgar in 1805, where the bulk of the French navy was irreparably destroyed.
Napoleon had consequently decided to try and starve the British to subjection by means of the Continental Blockade. This was an attempt to close all the ports of continental Europe from British shipping. For this to be effective, which it never was, all ports of continental would have to be under Napoleons control, directly or indirectly.
The only exceptions to this rule by the time were Denmark and Portugal.
Denmark, Sweden, and Russia had had an armed union of neutrality to enforce the independence of their shipping, but this was destroyed by a British attack on Copenhagen in 1801, and when the British returned in August 1807 and besieged and bombed an undefended Copenhagen killing thousands of civilians, the Danes had been pushed into the arms of Napoleon. Consequently only Portugal had to be forced into submission.
To accomplish this, Napoleon saw an opportunity to kill two birds with one stone: Spain had been an ally of France for a long time, and that had kept French forces out of Spain, and French influence at bay. The blockade of Britain had therefore not been taken as seriously in Spain, as Napoleon had hoped for, and an invasion of Portugal through Spain would allow the French to place troops in the country, while at the same time ending the Portuguese problem.
French troops in Spain
So, in October 1807, Napoleon sent a force of 25,000 French commanded by marshal Junot into Spain, and he reached Lisbon uncontested on the 1st of December. The supply line of Junot was long and stretched all the way back through the friendly Spain and into France. This did not remain so for long, however. Napoleon had intervened unwisely in some complicated affairs of the Spanish royal family, and soon Spain turned hostile. To relieve the French in Portugal, Napoleon sent an army of 82,000 men into Spain under command of Murat. Murat occupied large parts of the country, and moved into Madrid in March 1808.
The French had already now antagonised the Spanish population which rose against the French in Madrid in May and all over the countryside, as urged to by the Spanish nobility and clergy bacause of the abovementioned French meddling in the affairs of the royal family. The French army was successful against these initial uprisings, and fought well against the Spanish regulars who faced them, but with the people against them, the French were unable to secure their supply lines and rear guards. This meant that large contingencies had to be left along their path to occupy the roads, and fortresses.
The French consequently got stuck in a siege of Saragossa, were repelled at Valencia, and 18,000 French were forced to surrender at Bailén. The situation was chaotic, and the British soon decided to intervene. 15,000 British troops landed in Portugal on 1 August under the leadership of Sir Arthur Wellesley the later duke of Wellington and nemesis of Napoleon at Waterloo in 1815 and defeated the French at Vimeiro on the 21st of August. After Vimeiro, all the French captured were sent back to France by the British in the absence of Wellesley.
After much fighting and spectacular French failures, Napoleon decided to go to Spain himself, and finish of the enemy. He brought with him forces to raise the total strength to more than 300,000. He defeated the Spanish army, marched into Madrid, then defeated the British, who evacuated and left through Coruña. He then considered the war to be over, and left again for Austria, taking large forces with him. Spain was now formally under the control of Napoleons brother, King Joseph.
But the British soon returned, again under the command of Wellesley, together with British trained Portuguese, Germans, and other nationalities. Assisted by the British and remnants of the Spanish regular forces, the guerrillas were able to harass the French disastrously. Wellesley was able to secure Portugal, and fortified himself at Lisbon. Again, and again, French onslaughts on Portugal and Lisbon had to be abandoned.

The French let the civilian population suffer from the French frustrations and anger, and resorted to mass murder, extensive plundering and raping. The Spanish reacted, as could be expected, by attacking the French more and more Frequently. This soon became a downwards spiral, and the French lost control of larger and larger parts of the country. Several times, the British, in cooperation with the Portuguese and remaining Spanish regulars attempted to first secure Portugal, then march into Spain. But they were unable to do that, as the French forces were still formidable in conventional battle.
The French suffered from many serious problems with their leadership: Napoleon never returned after 1809, but he still tried to command the troops and lead the administration from Paris. This gave much confusion, since the formal ruler of Spain was King Joseph, who did not have much to say against the marshals of France, and in fact did not seem to be interested in the affairs of his kingdom. The marshals themselves couldnt agree, and as the only one with authority over them was Napoleon, the leadership wasnt as dynamic, as the French staff organisation was known for.
Many separate offensives were launched by the marshals, and they each fought their own separate wars, in their own provinces against the civilians. That was another mistake in the leadership of the French. The army corps had each been assigned a province or territory to rule. This meant that there was virtually no unity of effort. Each force was relatively small and could not call on the other formations, as they would be busy too. Therefore, out of a force of more than 200,000 troops, the French were only able to mobilise about 60,000 for battle.
