Why is Gustavus Adolphus called the Lion of the North?

Protestant writers of his own day cast him as the biblical lion from the north coming to save God's people. The Scottish colonel Robert Monro, who served in his army, called him the Lion of the North, the invincible King of Swedes, in a memoir printed in 1637.

What was his greatest victory?

Breitenfeld, north of Leipzig, on 17 September 1631. After his Saxon allies fled, his flexible Swedish brigades turned to face Tilly's flank attack, and the king's cavalry captured the imperial guns. Tilly lost thousands of men and all his artillery, and northern Germany lay open to Sweden.

Why did Gustavus Adolphus enter the Thirty Years' War?

Historians give several reasons. Habsburg armies held the Baltic coast and threatened Sweden. German Protestantism seemed close to defeat. And Sweden wanted Baltic land and revenue. He told his own Riksdag mainly about the danger to Sweden. France later paid him subsidies to fight the Habsburgs.

Did Gustavus Adolphus fight Poland?

Yes, for most of his reign. His cousin Sigismund III of Poland claimed the Swedish crown. Gustavus took Riga in 1621 and invaded Prussia in 1626, but Stanisław Koniecpolski fought him hard, defeating his cavalry at Trzciana in 1629. The Truce of Altmark that year still favored Sweden.

What military reforms did Gustavus Adolphus make?

He raised Swedish regiments by conscription, cut his units smaller and thinner, drilled musketeers to fire in salvos, gave infantry light regimental guns and taught cavalry to charge with the sword. Historians still debate whether these changes amounted to a military revolution, as Michael Roberts argued.

Gustavus Adolphus: Sweden's Lion of the North and His Wars

Q: Who was Gustavus Adolphus?

Gustavus Adolphus, Gustav II Adolf in Swedish, was king of Sweden from 1611 to 1632. He made Sweden a great power, fought Denmark, Russia and Poland, reformed his army, entered the Thirty Years' War in 1630, won at Breitenfeld in 1631 and was killed at Lützen in 1632.

Q: How did Gustavus Adolphus die?

He was killed at the Battle of Lützen on 16 November 1632, 6 November by the Swedish calendar. Leading a cavalry charge in fog and smoke, he was hit in the arm, lost control of his horse and was shot and stabbed several more times by imperial horsemen. His army fought on and held the field.

Quick answer

Who was Gustavus Adolphus?

Gustavus Adolphus (1594 to 1632), Gustav II Adolf in Swedish, was king of Sweden from 1611. He ended wars with Denmark and Russia, took Livonia from Poland, rebuilt the Swedish army, and in 1630 entered the Thirty Years’ War. He crushed Tilly at Breitenfeld in 1631 and was killed leading a cavalry charge at Lützen in 1632.¹

He reigned for twenty-one years and spent most of them at war. In two campaigning seasons in Germany he took a small, poor northern kingdom to the Rhine and the Danube, and his death in battle made him a Protestant martyr. To Poles he was the usurper’s son who invaded Prussia. To many Germans, a foreign warlord: long after the war, children were still threatened with “the Swede.” This is the life behind the legend, with each side’s view of him.²

Early life: a usurper’s heir

Gustavus was born in Stockholm on 9 December 1594 by the Swedish calendar (19 December by the Gregorian calendar), the eldest son of Duke Charles, the future Charles IX, and his second wife, Christina of Holstein. His father had driven his own nephew, Sigismund III Vasa, who was also king of Poland, off the Swedish throne in 1599. That usurpation shaped the boy’s whole life: the Catholic Polish Vasas never gave up their claim to Sweden, and the quarrel set the two kingdoms fighting on and off for sixty years.³

His education was run by the Swede Johan Skytte and the Brandenburg nobleman Otto von Mörner. Wittich calls it largely German, and says the king spoke German like a native. He was also schooled in the new Dutch ideas of warfare, and his father brought him into affairs of state early: according to the Gale encyclopedia he stood in for the ailing king at the Riksdag of 1609.⁴

King at sixteen: three wars at once, 1611 to 1617

When Charles IX died in October 1611, Gustavus was some weeks short of seventeen. The high nobility made him buy the crown with a charter that guaranteed its privileges and a share of government through the Council of State. It was drafted by Axel Oxenstierna, who became chancellor and, for the rest of the reign, the king’s closest partner: an aristocrat who believed in a strong nobility working beside a king who believed in a strong crown.⁵

He inherited wars with Denmark, Russia and Poland. Denmark was winning, and by the Peace of Knäred in 1613 Sweden had to pay a huge ransom for Älvsborg, its only port on the North Sea. In the words of the German biographer Karl Wittich, he made peace “not as he wished, but as he could.”⁶

Russia went better. Gustavus learned his trade in hard, indecisive campaigns there, and the Peace of Stolbovo in 1617 gave Sweden Ingria and Kexholm. Russia was cut off from the Baltic, and Sweden’s Finnish and Estonian lands were joined by a continuous belt of territory.⁷

At home he and Oxenstierna built a modern state. A supreme court was set up in 1614, permanent boards for the treasury, chancery, war and the navy followed, the Riksdag was organized into four estates, the first gymnasia were founded and Uppsala University was well endowed. Many new towns were chartered, Gothenburg among them. Historians still argue how much of this was the king’s own work. The Gale encyclopedia credits Oxenstierna with most of it, except the army.⁸

Against Poland: Riga, Prussia and Trzciana, 1621 to 1629

In 1620 Gustavus married Maria Eleonora of Brandenburg. The next year, while Poland was fighting the Ottomans, he renewed the war with Sigismund and took Riga in 1621, then most of Livonia. In January 1626 at Wallhof, in Courland, his reorganized army beat the Polish-Lithuanian cavalry that had routed his father’s army at Kircholm in 1605.⁹

In the summer of 1626 he carried the war to Prussia, landing at Pillau and taking the towns of the Vistula delta, among them Elbląg and Tczew, while his ships blockaded Gdańsk and charged its skippers heavy tolls. The aim was to take hold of the Vistula and its trade. The Polish historian Szymon Wachoń sees the war as part of Sweden’s drive for mastery of the Baltic, with Sigismund’s claim to the Swedish crown used as the pretext.¹⁰

Poland fought back. In the autumn of 1626 Sigismund’s own army fought the Swedes around Gniew (Mewe). A review of Polish scholarship on dzieje.pl says the Swedish advance was halted there, while Szymon Wachoń counts the campaign among the setbacks that made the king call in Field Hetman Stanisław Koniecpolski, a veteran of the steppe wars against Tatars and Cossacks, who took command in Prussia. Gustavus was badly wounded twice in 1627, once near Gdańsk in May and again at Tczew (Dirschau) in August. At Tczew, Jakub Pokojski counts some 12,500 Swedes against 3,000 Poles at the start, yet the battle ended undecided when the king was hit. Swedish tradition long called it the first Swedish victory over the hussars, a claim Pokojski rejects.¹¹

At sea the small Polish royal fleet beat a Swedish squadron off Oliwa on 28 November 1627, capturing the Swedish flagship. The blockade of Gdańsk was lifted, but only until the spring, and the war on land went on.¹²

The worst moment came in late June 1629 at Trzciana (Honigfelde), where Koniecpolski, now joined by an imperial corps under Hans Georg von Arnim, caught the Swedish cavalry covering the king’s withdrawal and routed it. Dodge dates the fight to 27 June, the Polish History Museum to 25 June. Gustavus was in the thick of it and nearly captured: by Dodge’s account a Polish horseman seized him by his shoulder belt, and he slipped out of it to escape. A local Polish legend says he dropped his mace into a lake as he fled.¹³

The war was ended not by battle but by diplomacy. Dutch, French and English envoys, the Dutch eager to reopen Baltic trade and the French and English to turn Sweden against the Habsburgs, brokered the six-year Truce of Altmark in September 1629. It let Sweden keep Livonia north of the Daugava and most of the Prussian ports, and gave it the right to levy tolls on Gdańsk’s trade. Read the whole story in the Polish-Swedish War of 1600 to 1629.¹⁴

The army that changed warfare

Gustavus built his army around Swedish provincial regiments, well trained and regularly paid when the treasury allowed, and filled it out with hired Scots, Germans and others. He cut units smaller and thinner than the deep Spanish-style squares, mixed musketeers with pikemen, and drilled the shot to fire by ranks in salvo.¹⁵

His artillery was the wonder of its day. He standardized calibers and gave the infantry light regimental guns that could keep pace with the foot, at one stage even experimenting with leather guns. He taught his cavalry to charge home with sword and pistol at a gallop instead of trotting up to fire.¹⁶

He also made the soldiers dig. The Scottish colonel Robert Monro, who served him for years, wrote that the king could never rest until his earthworks were finished, “for when he was weakest, he digged most in the ground.” His famous articles of war, read to the army before the Riga campaign of 1621, set up regimental and general courts-martial and held the troops to strict discipline.¹⁷

Monro’s own regiment, raised by Sir Donald Mackay, was one of many Scottish units in Swedish pay, and his memoir of 1637, Monro, His Expedition, is one of the best eyewitness accounts of the king’s wars. Fletcher, who drew on it heavily, counts it among the first-hand evidence for the reign.¹⁸

How new was all this? In 1955 the historian Michael Roberts argued that the tactical reforms of Maurice of Nassau and Gustavus started a “military revolution” that produced bigger armies and stronger states. Geoffrey Parker, his first major critic, challenged the timing and the causes in 1976, putting artillery fortresses and sieges at the center instead, though he accepted that the scale of war was revolutionized. Jeremy Black went further and placed the real change in army size and organization after 1660. Gustavus remains at the heart of that debate.¹⁹

Into Germany, 1630 to 1631

By 1628 Wallenstein’s imperial army stood on the Baltic coast, and Gustavus and the Danes together saved Stralsund from it. To Gustavus, Wittich writes, Stralsund and Wismar were the keys to the Baltic from the German side. In the speech to the Estates that Fletcher quotes, he said little of oppressed Protestants and much of the danger to Sweden: the “Papists” held the Baltic ports and meant to destroy Swedish trade.²⁰

Historians have weighed his motives ever since. Britannica’s article by Michael Roberts stresses the defense of Protestantism and of the Baltic. The Norwegian national encyclopedia adds economic, political and dynastic aims. Peter Wilson sees a Sweden that left an unprofitable war in Poland for easier pickings in the Empire to sustain its Baltic empire.²¹

At midsummer 1630 the fleet reached the island of Usedom, and the army landed near Peenemünde. Fletcher tells how the king went ashore first, knelt to pray, and took a spade to start the entrenchments. Schiller too has him giving thanks on his knees. His enemies mocked him as the “Snow King”: Wallenstein’s letters, Fletcher notes, sneer at a “King of snow and ice” who would melt in Europe.²²

He moved fast. Stettin opened its gates in July, giving him the mouth of the Oder and a base in Pomerania, and through the winter the Swedes cleared the coast. In April 1631 they stormed Frankfurt an der Oder.²³

The German Protestant princes held back. While Gustavus haggled with the electors of Brandenburg and Saxony, Tilly’s army stormed the Protestant city of Magdeburg on 20 May 1631 and burned it, one of the worst atrocities of the war. Critics blamed Gustavus for coming too late. Dodge defends him, arguing that he could not march on without secure allies behind him. Catholic France, meanwhile, had agreed in January 1631 to subsidize the Swedish war against the Habsburgs.²⁴

Breitenfeld, 1631: his greatest victory

Magdeburg’s fate, and Tilly’s invasion of Saxony, finally pushed Elector John George into alliance. On 17 September 1631 (7 September in the Swedish calendar), north of Leipzig, the joined Swedish and Saxon armies met Tilly. Dodge, following the official Swedish list, counts 26,800 Swedes and perhaps 45,000 allied troops in all, against an imperial army he puts well short of 40,000. The Saxons broke and fled, but the Swedish brigades turned to face the attack on their open flank, and the king led his cavalry into Tilly’s rear, took the imperial guns and turned them on their owners. By Dodge’s count Tilly lost 7,000 killed, 6,000 wounded or captured and all his artillery, against some 2,100 Swedish killed and wounded.²⁵

The victory made Gustavus the hero of Protestant Europe: a memorial stone at Breitenfeld still says that there he saved freedom of belief for the world. The London news-book The Swedish Intelligencer marveled in 1632 at a commander “so vigilant upon every occasion, that there were few great actions which himself was not at one end of.” Read the full account of the Battle of Breitenfeld.²⁶

Instead of marching on Vienna, Gustavus turned west and south into the rich Catholic bishoprics. Würzburg, Frankfurt and Mainz fell, and he wintered at Mainz. Schiller, writing in the 1790s, has him crossing Germany “with the sword in one hand, and mercy in the other.”²⁷

Bavaria and the Alte Veste, 1632

In April 1632 he forced the crossing of the river Lech near Rain under the cover of his massed guns. A cannon ball shattered Tilly’s leg, and he died of the wound at Ingolstadt on 30 April. In May the Swedes entered Munich, the capital of the Catholic League’s leader, Maximilian of Bavaria. Gustavus was then at the height of his power, planning a permanent Protestant league in Germany under Swedish leadership.²⁸

The emperor recalled Wallenstein, who raised a new army and dug in near Nuremberg. For weeks the two armies starved each other: by Dodge’s count, some 125,000 people crowded into the city, sickness spread and dead horses lay unburied.²⁹

At the start of September (late August by the Swedish calendar) Gustavus stormed Wallenstein’s camp at the Alte Veste and was beaten off with heavy losses. The sole of his boot was shot away. The authors of a 2017 study of the Lützen battlefield write that this undecided clash cost him his reputation for invincibility.³⁰

Lützen, 1632: how did Gustavus Adolphus die?

When Wallenstein turned north into Saxony, the king followed and caught him at Lützen, south-west of Leipzig, on 16 November 1632 (6 November in Sweden). Fletcher gives the king about 18,000 men against 25,000 imperial troops, with 8,000 to 10,000 more expected under Pappenheim. William Brockington’s account for EBSCO has 18,000 against 28,000. The town was burning and fog and smoke hid the field. Leading the Småland cavalry in a charge, the king had his elbow shattered by a musket ball, lost control of his horse Streiff and was wounded several more times before he died. Fletcher adds that he wore only a hat and a riding coat that day, because his breastplate had galled him since his Tczew wound, and that imperial horsemen stripped the body.³¹

His army fought on, and Wallenstein was the first to order a retreat, but who really won is still debated. Between 6,000 and 9,000 soldiers died in the battle, by the count of the 2017 study.³²

The body was laid in the village church at Meuchen, then carried home to Sweden. Queen Maria Eleonora had the relics of Lützen kept, and the Royal Armoury in Stockholm still shows his bloodstained clothes and Streiff, his horse, mounted after its death. He lies in the Riddarholm Church in Stockholm, in a burial chapel he had ordered built before he left for Germany. His only child, Christina, born in December 1626 and so not yet six, succeeded him, with Oxenstierna governing for her. See the full story of the Battle of Lützen.³³

The battlefield still gives up its dead. In 2011 archaeologists found a mass grave of 47 soldiers there, men aged between 15 and 50, many killed by handgun wounds to the skull. It was lifted in a single block and later became the centerpiece of an exhibition at the State Museum of Prehistory in Halle.³⁴

Was Gustavus Adolphus a great commander?

His admirers had no doubt. Monro called him “the Lyon of the North, the invincible King of Swedes,” and the American soldier-historian Theodore Dodge named him “the father of modern war,” great “because he knew when to be cautious and when to be bold.” He combined infantry, cavalry and guns, cared about supply and winter clothing, and campaigned through winters that sent other armies into quarters.³⁵

He also had failures. Koniecpolski held him in check in Prussia and routed his cavalry at Trzciana. The Alte Veste was a bloody repulse. And his habit of leading charges in person, which inspired his men, killed him at thirty-seven. Wittich notes that he exposed his life again and again in skirmishes, to the dismay of those around him. The Gale encyclopedia judges that he preferred to fight on the defensive, letting enemies wreck themselves on Swedish firepower.³⁶

Legacy: Lion of the North, Snow King, invader

Sweden came out of his reign a great power, confirmed by the Peace of Westphalia in 1648, and Swedes still call him Gustav Adolf the Great. In Protestant Germany he became a savior: a biography printed for the bicentenary of Lützen in 1832 called him the savior of Germany and the martyr of Protestant freedom of belief.³⁷

For the bicentenary of his death in 1832, a Leipzig man, August Schild, proposed a penny collection for poor Protestant congregations instead of a monument, and this led to the Gustav-Adolf-Stiftung, today the Gustav-Adolf-Werk, the diaspora charity of the German Protestant churches, which still bears his name.³⁸

The view from the other side was darker. For many Catholics he was a foreign tyrant who sacked their lands. For Poland he was the king who used a dynastic quarrel to seize Livonia and tax the Vistula trade. Modern scholars such as Peter Wilson warn against reading the war as a simple Protestant crusade: religion mattered, but so did the Swedish crown’s hunger for Baltic territory and revenue.³⁹

The memorial where his body was found, a boulder under a canopy designed by Schinkel with a chapel built in 1907, still draws Swedes and Germans, and anniversaries on 6 November, the date of Lützen in the old Swedish calendar, have been kept there since at least 1832. Compare him with his great opponent Stanisław Koniecpolski, with Turenne, who learned his trade in the same war, or see where he stands among the greatest military commanders and the most influential military leaders in history.⁴⁰
