What happened at the Battle of White Mountain?

On 8 November 1620, on a low hill on the western edge of Prague, the armies of Emperor Ferdinand II and the Catholic League routed the army of the rebel Bohemian estates in an hour or two. King Frederick V, the Winter King, fled into exile, Prague surrendered, and the Habsburgs crushed the revolt with executions, confiscations and forced re-Catholicization, ruling Bohemia as hereditary lords until 1918.1

It was a Sunday, and the gospel read in the Catholic camp that morning told the faithful to render unto Caesar the things that are Caesar's. Across the valley, on the bare slope called the White Mountain, the army of the rebel kingdom of Bohemia waited behind two hastily dug redoubts, hungry, unpaid and close to mutiny. Its king was not even there: Frederick V was dining in Prague with two English envoys. By the time he rode out, his army was already in flight. The battle that ended the Bohemian revolt, and with it the independence of the Bohemian estates for three centuries, was over almost before it began.2

Background: from the window of Prague Castle

Bohemia before 1618 was a kingdom of many faiths, Lutherans, Calvinists and heirs of Jan Hus alongside a Catholic minority, and its religious freedom rested on a royal charter granted by Emperor Rudolf II in 1609. His successor Matthias evaded it, and in 1617 the Bohemian diet was induced to accept his cousin Ferdinand of Styria, a zealous Catholic, as the next king. Disputes over Protestant churches built on Church lands soon followed, and one of them was pulled down.3

On 23 May 1618 a band of Protestant noblemen led by Count Heinrich Matthias von Thurn burst into Prague Castle and threw two of the king's regents, Jaroslav Martinitz and Wilhelm Slawata, and their secretary out of a high window. The Defenestration of Prague began the revolt of the Bohemian estates and, as it turned out, the Thirty Years' War. The estates set up their own government and raised an army.4

When Matthias died in March 1619, Ferdinand succeeded him as king and was elected Holy Roman Emperor. The Bohemians deposed him, and on 26 August 1619 their diet offered the crown to Frederick V, the Calvinist Elector Palatine and son-in-law of James I of England. Frederick accepted. The Jesuits, Gardiner records, whispered that he would be only a winter king, and the name stuck.5 › Battle of Humenné, 1619

Frederick had been chosen for the friends he was supposed to bring, and they did not come. The Protestant Union would not fight for him, and James I preferred to mediate. Ferdinand did far better. Maximilian of Bavaria, head of the Catholic League, agreed to send an army in return for Frederick's electoral title; the Lutheran Elector of Saxony, John George, joined the Emperor; and Spain sent troops under Spinola into Frederick's own lands on the Rhine. In the summer of 1620 the Union signed a treaty of neutrality with the League at Ulm, and Frederick stood alone.6

Armies and commanders

The Catholic side had two armies. The Imperial army was led by Count Charles Bonaventure de Bucquoy; the Catholic League army by the Walloon Count Johann Tserclaes Tilly, with Maximilian of Bavaria present in person. On 20 September 1620 they crossed into Bohemia together and turned toward Prague.7

The Bohemian army was commanded by Christian of Anhalt, Frederick's chief adviser, with Count Thurn among his officers and Hungarian horsemen sent by the Prince of Transylvania, Gabriel Bethlen, as allies. Gardiner judged that Anhalt, though brave, did not inspire confidence. His men had not been paid for months: Gindely describes an army in a constant state of mutiny, and the Hungarians plundered friend and foe alike.8

The numbers are uncertain. EBSCO gives the Imperial army about 15,000 men and the League about 10,000, against some 15,000 Bohemians, many of them untrained volunteers. Herodote.net gives 21,000 Bohemians against about 25,000 Imperials. Gindely, writing in the 1880s, thought sickness had cut the League to about 12,000 and the Imperials to under 15,000, and that the two armies were perhaps nearly equal in numbers but not in spirit.9

The battle in phases

The race to Prague. For weeks Anhalt shadowed the Catholic armies across western Bohemia without risking a battle. When they slipped away toward Prague in early November, he hurried to get there first, and in the night of 7 to 8 November he reached the White Mountain, a low plateau on the western edge of the city. He had two redoubts dug and placed his few cannon in them. Parker writes that he hoped his opponents would not dare to attack so late in the year.10

The position. The ground favored the defenders. The Bohemians held the high ground, with the royal game reserve of the Star (Hvězda) and its hunting lodge, a star-shaped summer palace, covering their right flank and a brook below them. The Catholic armies had to cross the brook at the foot of the slope before they could attack.11

The council. On the Catholic side the commanders disagreed. Bucquoy, wounded a few days earlier, wanted to avoid an attack and march around the position; Tilly and Maximilian wanted to fight at once. A friar who accompanied the army, the Carmelite Father Dominicus in Gindely's account, a Dominican in Gardiner's, urged them to attack in God's name, and Bucquoy gave way.12

The attack. Around midday the Catholic troops crossed the brook and went up the slope. Tilly sent his well-trained and well-equipped soldiers straight at the Bohemian line, and Herodote.net writes that the Imperials settled the matter in the afternoon.13

Turning point: the panic

Then the Bohemian army broke. The Hungarian horsemen, on whom Frederick had counted most, fled almost without fighting, and their flight spread panic through the whole army. The redoubts and their guns fell to the attackers, and the Bohemians fled in every direction, down the slopes toward Prague and the Vltava. The battle had lasted about an hour by Parker's and Gindely's accounts, about two hours by EBSCO's and Herodote.net's.14

The losses were small for so decisive a day. Herodote.net counts about 2,000 Bohemian dead against a few hundred on the Imperial side; Gindely, from the reports he studied, gives 1,600 bodies found on the field and perhaps a thousand drowned, against 250 Imperial and League dead. An English envoy in Bohemia, quoted by Parker, saw at once what mattered: the loss of soldiers was not much unequal, but the loss of cannon, baggage and reputation gave the Imperialists Bohemia by conquest.15

Aftermath

Frederick had set out from Prague Castle too late, and on the way learned that his army was beaten. The next morning the king, the queen and their court left the city in haste. Frederick never saw Bohemia again; he ended his days in exile in the Netherlands. Thurn fled to Moravia.16

Prague fell at once, and its citizens, who surrendered without resistance, hoped in vain for mercy. Imperial soldiers plundered the city and the countryside, and suspected rebels were killed without trial. Moravia, Silesia and Lusatia submitted within months.17 › Battle of Khotyn, 1621

The reckoning came the next summer. Leaders of the revolt were arrested in February 1621 and tried by a special court. On 21 June 1621 twenty-seven of them, nobles and burghers, were executed on Prague's Old Town Square. The rector of the university, Jan Jesenius, had his tongue cut out before he was beheaded, and the heads of the executed were displayed on the Old Town Bridge Tower.18

The lands of everyone who had supported the revolt were confiscated and sold cheaply to Catholic loyalists, and a new Catholic and largely German-speaking nobility took the place of the old one. Protestants were ordered to convert or leave the kingdom; many families went into exile, among them the scholar Jan Amos Komenský (Comenius), and the university of Prague was handed to the Jesuits. In 1627 Ferdinand imposed a new constitution that made the crown hereditary in his house, moved the Bohemian chancellery to Vienna and reduced the diet to a shadow.19

Legacy and memory

For the Habsburgs and the Catholic world White Mountain was a triumph, the first great victory of the Thirty Years' War. Parker calls it the battle that let the Habsburgs end constitutional rule in Bohemia and its neighbors and set up an authoritarian government that lasted three centuries, until Czechoslovakia was created in 1918. The war itself moved on, to the Palatinate, Denmark and northern Germany, and lasted until the Peace of Westphalia in 1648.20 › Battle of Lutter, 1626

For Czechs it became the great national catastrophe. Radio Prague calls it a defining moment in the history of the Czech lands; the exile of so many nobles, burghers and scholars was, in the words of the Prague theologian Pavel Černý, a blow from which the kingdom did not recover for centuries. The twenty-seven executed are remembered as martyrs of the nation, and every Czech schoolchild learns the story of the battle.21

Visiting the battlefield today

The battlefield lies in the Prague district that bears its name, Bílá Hora, where a memorial marks the site of the fighting, and costumed reconstructions of the battle are held nearby. Next to it is the Hvězda (Star) game reserve, founded in 1534, with its Renaissance summer palace built on a six-pointed star plan, where Maximilian and Bucquoy spent the night after the battle. In the city, the Old Town Square and the Old Town Bridge Tower recall the executions of 1621.22 › 8 November in military history
