TheBattle of Nördlingen,[c] fought over two days from 5 to 6 September 1634, was a major battle of theThirty Years' War. AImperial-Spanish force led by theCardinal-Infante Ferdinand andFerdinand of Hungary inflicted a crushing defeat on theSwedish-German army led byGustav Horn andBernhard of Saxe-Weimar.
By 1634, the Swedes and their German allies occupied much of southern Germany. This allowed them to block theSpanish Road, an overland supply route running from Italy toFlanders, used to support Spain'swar against theDutch Republic. Seeking to re-open this, a Spanish army under the Cardinal-Infante linked up with Imperial forces nearNördlingen, which was held by a Swedish garrison.
Horn and Bernhard of Saxe-Weimar marched to its relief, but significantly underestimated the numbers they faced. After limited fighting on 5 September, on the 6th they launched a series of assaults south of Nördlingen, all of which were repulsed. Superior numbers allowed the Spanish-Imperial commanders to continually reinforce their positions, and Horn ordered his troops to withdraw. As they did so, they were outflanked by Imperial cavalry and retreat turned into a rout, with both Horn and his deputyScharffenstein among those taken prisoner.
Defeat forced the Swedes to withdraw fromBavaria, while in May 1635 their major German allies signed thePeace of Prague withEmperor Ferdinand II. In response,France now intervened on behalf of Sweden and theDutch Republic by declaringwar on Spain, and entering the Thirty Years' War as an activebelligerent. As a consequence, some suggest Nördlingen was the pivotal battle of the Thirty Years' War.[6]
Swedish intervention in the Thirty Years' War began in June 1630 when nearly 18,000 troops underGustavus Adolphus landed in theDuchy of Pomerania. Provided withsubsidies as part of aFrench policy of opposition to theHabsburgs, and supported bySaxony andBrandenburg-Prussia, Gustavus won a series of victories overImperial forces, includingBreitenfeld in September 1631, thenRain in April 1632.[7]
Despite the death of Gustavus atLützen in November 1632, Sweden and its German allies formed theHeilbronn League in April 1633, once again financed by France.[8] In July, the coalition defeated an Imperial army atOldendorf inLower Saxony; a few months later,Emperor Ferdinand II dismissed his leading generalAlbrecht von Wallenstein, who wasassassinated by Imperial agents in February 1634.[9]
The removal of Wallenstein made Emperor Ferdinand more reliant on the Spanish, Since their primary objective was re-opening theSpanish Road to support theircampaign against theDutch Republic, the focus now shifted to theRhineland andBavaria.[10]Cardinal-Infante Ferdinand, newly appointed Governor of theSpanish Netherlands, recruited an army of 11,700 in Italy, which in May crossed theAlps through theStelvio Pass. AtRheinfelden, he linked up with forces previously commanded by theDuke of Feria, who died in January 1634. This brought his numbers up to 18,000 infantry and 4,000 cavalry.[11]
The Swedes and their German allies largely operated as separate units, each with their own objectives. WhileJohan Banér andHans von Arnim invadedBohemia,Gustav Horn tried to block the Spanish by investingÜberlingen, andBernhard of Saxe-Weimar sought to consolidate his position inFranconia by takingKronach.[12] Neither was successful and leftRegensburg isolated, which was besieged on 23 May by an Imperial army of 25,000 underFerdinand of Hungary. Horn and Bernhard met atAugsburg on 12 July and marched towards the Bohemian border, hoping the threat of them combining with Arnim would force Ferdinand to abandon the siege.[12]
Although they defeated an Imperial blocking force underJohann von Aldringen atLandshut on 22 July, the siege continued and Regensburg surrendered on 26 July.[13] With 15,000 men, Ferdinand marched down theDanube (see Map) and reachedDonauwörth on 26 August, where he turned aside to besiege the Swedish-held town ofNördlingen, which had to be taken before continuing his advance. Horn and Bernhard marched toBopfingen but delayed their attack; with both sides short of supplies and suffering from plague, they were confident the outnumbered Imperials would have to withdraw.[14]
However, on 2 September the Imperial and Spanish armies linked up, and Nördlingen nearly fell to an assault two days later.[3] Horn and Bernhard were joined by 3,400 men underScharffenstein, giving them around 26,000 in total, although this included 8,000 poorly trainedWürttemberg militia, many of whom had previously served in the Imperial army. Horn wanted to wait for additional troops, which were a week's march away, but Bernhard urged an immediate attack, claiming the Spanish reinforcements numbered less than 7,000. The true figure was over 18,000, which meant the combined Spanish-Imperial army totalled over 33,000 and outnumbered their opponents.[15]

Early on 5 September, the Protestant army broke camp, feinted west as if retreating toUlm, then moved across country to seize a line of hills two kilometres south of Nördlingen.[3] From west to east, these included the Himmelrech, Ländle, Lachberg, Heselberg, and Albuch, the latter in particular being key to the Spanish left. TheCardinal-Infante ordered these to be occupied, with veterans from theTercio of Fuenclara holding the Heselberg.[16]
Later in the afternoon, infantry led byBernhard of Saxe-Weimar made contact with Spanish and Imperialpickets on the Himmelreich, which was quickly captured. They then occupied the Ländle and Lachberg hills, before their advance was stopped by Spanish troops holding the Heselberg. Despite a heavy artillery bombardment, a number of Swedish assaults were repulsed, before Horn ordered a halt just before midnight.[16]
The delay allowed Cerbellón and theTercio of Toraldo time to construct defensive positions on the Albuch, and around 2:00 am on 6 September, the Heselberg was abandoned.[17][18] This meant it was defended by 6,600 Spanish veterans led by Leganés and Cerbellón, 1,500 Bavarian infantry underOttavio Piccolomini, a battery of 14 guns, along with 2,800 cavalry.[19] The rest of the Imperial army was left holding a line running north to Nördlingen.[18]
The defenders of the Albuch faced 8,800 infantry commanded by Horn, along with 4,000 cavalry and 800 dragoons, led by Scharffenstein.[20] Bernhard and the remaining troops took position opposite their Imperial counterparts, with 2,000–2,500 Württemberg militia in the rear protecting the baggage train. Bernhard was tasked with preventing the Imperial right reinforcing their colleagues on the Albuch, although it soon became clear he was badly outnumbered, and was thus restricted to limited skirmishing.[21]

At 5:00 am on 6 September, the Swedish artillery opened fire, followed by a general assault on the Albuch led by the Scottish and Vitzhum brigades, along with 3 cavalry squadrons. Scharffenstein's cavalry were quickly repelled by their Spanish counterparts, but the relatively inexperienced infantry gave ground.[22] Horn believed he was on the verge of a great victory, but as the Imperial troops fell back in disorder, they were rallied by veterans from theTercio of Idiáquez, who drove forward in a sudden counterattack, taking their opponents by surprise and re-forming their lines.[23][17] By 6:00 am, Imperial forces were back in control of the Albuch.[22]
Whilst reorganising his scattered infantry, Horn kept up the pressure by ordering a second attack, which was stopped short of the Spanish positions with heavy losses. followed by another attack with all available troops, which also failed.[24] With his forces largely unengaged, at 7:30 am Bernhard transferred the Thurn brigade to join a series of assaults, which persisted for another hour without success.[25] Their numerical superiority allowed Leganés and Gallas to send a constant stream of reinforcements to support those holding the Albuch.[26]

Trying to prevent this, Bernhard moved his cavalry against the Imperial right, but they were repulsed and forced back to their previous positions. The troops assaulting the Albuch were exhausted, and after one last attack around 10:00 am, Horn ordered them to hold their positions until nightfall, before withdrawing towards Ulm. However, seeing their adversaries pulling back, the Spanish-Imperial troops began a general advance, routing Bernhard's cavalry and allowingCroat light cavalry to outflank his infantry. At the same time, combined Imperial, Bavarian, and Spanish forces attacked the Heselberg, driving those holding it into the woods.[27]
Horn's men were now attacked on two sides, from troops advancing from the Albuch, and Imperial cavalry charging out of the woods, cutting off his retreat.[28] His army disintegrated, and suffered between 12,000 and 14,000 casualties, compared to 3,500 for their opponents.[d] This included 4,000 prisoners, most of whom were enrolled in the Imperial army. Scharffenstein, previously a senior Bavarian commander, was captured and later executed for treason, while Horn was held in custody until 1642.[30] Bernhard and von Taupadel reachedHeilbronn with the survivors a few days later.[31]

Nördlingen effectively destroyed Swedish power in southern Germany, and has been described by some commentators as "arguably the most important battle of the war".[6] It has been also portrayed as "a Spanish victory," with victory owing much to the performance of the veteran tercios, while Cardinal-Infante Ferdinand performed well in what was his first battlefield command.[32] The Imperial army retook most of Württemberg and moved into theRhineland, while Ferdinand and his troops continued into theSpanish Netherlands, where he took up his appointment as Governor.[33]
Swedish ChancellorAxel Oxenstierna faced domestic pressure to end the war, stating defeat was "so terrible, it couldn't have been worse."[34] In December, two of their main allies,Saxony andHesse-Darmstadt, negotiated a peace agreement with Emperor Ferdinand, later formalised in the May 1635Treaty of Prague. Its terms included the dissolution of the Heilbronn and Catholic Leagues, and the treaty is generally seen as the point when the Thirty Years' War ceased to be primarily a German religious conflict.[35]
However, the collapse of the anti-Habsburg alliance in Germany now prompted direct French intervention. In February 1635,Cardinal Richelieu signed a treaty agreeing a joint Franco-Dutch offensive in the Spanish Netherlands, while a French army underHenri, Duke of Rohan, cut the Spanish Road by invading theValtellina in March.[36] This was followed in April by anew alliance with Sweden, as well as financing an army of 12,000 under Bernard of Saxe-Weimar in the Rhineland. In May, France formally declared war on Spain, starting the 1635 to 1659Franco-Spanish War.[37]
