The Second Schleswig War (Danish: 2. Slesvigske Krig; German: Zweiter Schleswig-Holsteinischer Krieg[1]) was the second military conflict due to the Schleswig-Holstein Question. The war began on February 1 1864 when Prussian forces crossed the border into Schleswig.

The war was fought between Denmark on the one side and Prussia and Austria on the other side. Like the First Schleswig War (1848–51), it was fought for control of the duchies because of succession disputes concerning the duchies of Holstein and Lauenburg when the Danish king died without an heir acceptable to the German Confederation. Decisive controversy arose due to the passing of the November Constitution, which integrated the Duchy of Schleswig into the Danish kingdom in violation of the London Protocol.

Reasons for the war were the ethnic controversy in Schleswig and the co-existence of conflicting political systems within the Danish unitary state.

The war ended on October 30 1864 with the Treaty of Vienna (1864) causing Denmark's cession of the Duchies of Schleswig, Holstein and Lauenburg to Prussian and Austrian administration, respectively.

Background

The secessionist movement from Denmark of the large German majority in Holstein and Southern Schleswig was suppressed in the First Schleswig War (1848–51), but the movement continued throughout the 1850s and 1860s, as Denmark attempted to integrate the Duchy of Schleswig into the Danish kingdom and proponents of the German unification expressed the wish to include the two Danish-ruled duchies Holstein and Schleswig in a 'Greater Germany'. Holstein was a part of the German Confederation and before 1806 a German fief and completely German, whereas Schleswig was a Danish fief and linguistically mixed between German, Danish, and North Frisian. Originally Schleswig was homeland of the Angles and Jutes, when, in the Viking Age, Denmark tried to increase its influence, which was finally rejected by the Holy Roman Empire after several wars with Denmark. However, the northern and middle parts of Schleswig (up to the Eckernförde Bay) originally spoke Danish. But in modern times the language in the southern half shifted gradually to German. In parts of the west coast of Schleswig the population spoke one of the North Frisian dialects. Holstein stayed completely German.

German culture dominated in the clergy and nobility, while Danish had a lower social status. For centuries, when the rule of the king was absolute, these conditions had created few tensions. When ideas of democracy spread and national currents emerged ca. 1820, identification was mixed between Danish and German.

To that was added a grievance about tolls charged by Denmark on shipping passing through the Danish Straits to pass between the Baltic Sea and the North Sea. To avoid that expense, Prussia planned the Kiel Canal, which could not be built as long as Denmark ruled Holstein.

Much of the dispute focused on the future successor of King Frederick VII of Denmark. In general terms, the Germans of Holstein and Schleswig supported the House of Augustenburg, a cadet branch of the Danish royal family, but the average Dane considered them too German and preferred the rival Glücksburg branch and Prince Christian of Glücksburg as the new sovereign. Prince Christian had served on the Danish side in the First Schleswig War in 1848-1851. At the time the king of Denmark was also duke of the duchies of Holstein and Schleswig. In 1848 Denmark had received its first free constitution and at the same time (and partly as a consequence) had fought a civil war with the Germans of Schleswig-Holstein in which Prussia had intervened.

Part of the peace treaty stipulated that the duchy of Schleswig should not be treated any differently than the duchy of Holstein in its relations with the Kingdom of Denmark. But during the revisions of the 1848 constitution in the late 1850s and early 1860s Holstein refused to acknowledge the revision, bringing a crisis in which the parliament in Copenhagen ratified the revision but Holstein did not. That was a clear breach of the 1851 peace treaty and delivered Prussia and the German union with a casus belli against Denmark.

Constitutional crisis

The adoption of the Constitution of Denmark in 1849 complicated matters further as many Danes wished for the new democratic constitution to apply for all Danes, including in the Danes in Schleswig. The constitutions of Holstein and Schleswig were dominated by the Estates system, giving more power to the most affluent members of society, with the result that both Schleswig and Holstein were politically dominated by a predominantly German class of landowners. Thus more systems of government co-existed within the same state: democracy in Denmark, and absolutism in Schleswig and Holstein.

The three units were governed by one cabinet, consisting of liberal ministers of Denmark who urged for economical and social reforms, and conservative ministers of the Holstein nobility who opposed political reform. This caused a deadlock for practical lawmaking. Moreover, Danish opponents of this so-called Unitary State (Helstaten) feared that Holstein's presence in the government and, at the same time, membership of the German Confederation would lead to increased German interference with Schleswig, or even into purely Danish affairs.

In Copenhagen, the Palace and most of the administration supported a strict adherence to the status quo. Same applied to foreign powers such as Great Britain, France and Russia, who would not accept a weakened Denmark in favour of Germany, nor that Prussia acquired Holstein with the important naval harbour of Kiel or controlled the entrance to the Baltic.

In 1858 the German Confederation deposed the 'union constitution' of the Danish monarchy, concerning Holstein and Lauenburg which were members of the Confederation. The two duchies were henceforth without any constitution, whereas the 'union constitution' would still apply to Schleswig and Denmark proper.

As the heirless King Frederick VII grew older, Denmark's successive National-Liberal cabinets became increasingly focused on maintaining control of Schleswig following the king's future death.

The king died in 1863 at a particularly critical time; the work on the November Constitution for the joint affairs of Denmark and Schleswig had just been completed with the draft awaiting his signature.

The newly appointed King Christian IX felt compelled to sign the draft constitution on November 18 1863, although expressing grave concerns in the process.

This action caused an outrage among the duchies' German population and a resolution was passed by the German Confederation at the initiative of the Prussian Prime Minister Otto von Bismarck. This resolution called for the occupation of Holstein by Confederate forces. The Danish government abandoned Holstein and pulled the Danish Army back to the border between Schleswig and Holstein. Most of it fortified itself behind the Danevirke. This order to retreat without combat caused adverse comment among some Danish private soldiers,[2] but the military circumstances made it wise to shorten the frontier needed to be defended. Also, as the administrations of Holstein and Lauenburg were members of the German Confederation, not pulling back might have caused a severe political crisis and perhaps war.

Strategy

There were so-called "flank positions" (near Æbeltoft (North), the fortified city of Fredericia (center), and Dybbøl in the south) designed to support the strategy of defending the peninsula of Jutland along the North-South axis using naval supremacy at sea to move the army North-South and hence trap the invading army in futile marches between these flank positions, denying the (assumed superior) invader the chance of forcing the defending army to a decisive battle, and giving the defending army the opportunity to swiftly mass and counter-attack weak enemy positions, besieging forces, or divided forces by shifting weight by sea transport. The political dimension of this strategy was to draw out the war and hence give time and opportunity for the "great powers" to intervene diplomatically and (it was assumed) such an intervention would always be to the advantage of (neutral) Denmark.

This strategy had been successful in the previous First Schleswig War.

Unrealistic expectations of the potency of the Danish army and incompetence at the political level had overruled the command of the army's wishes to defend Jutland according to the above plan and had instead favoured a frontal defense of Jutland on or near the historical defense (and legendary border) line at the Danevirke (near the city of Schleswig in the south).

Hence resources had been put into the Danevirke line and not into the flank positions, which stayed more battlefield fortifications than modern fortifications capable of withstanding a modern bombardment.

The problem with the Danevirke line was that perhaps the Danevirke line was relatively strong against a frontal assault, but the entire position could be easily encircled to the west as well as to the east (though with more difficulties). And hence a defense along the Dannevirke line was, correctly, anticipated by the Danish high command to be a trap, in which the Danish army would be surrounded and forced to give battle at hopeless odds.

When the Prusso-German army approached the "Danevirke line", the estuaries and marshes which had been planned to support the flanks of the Danevirke were frozen solid in a hard winter and the command of the Danish army disobeyed orders and ordered a full, orderly retreat back north to "the old Dybbøl" and its ill-prepared flank position. There is little doubt that the command of the army did not believe that they could successfully repulse a well-prepared German siege and consequent assault on the Dybbøl position, but instead assumed that the political level would come to sense and let the army be evacuated by sea and then fight the war on the principles of the North-South axis strategy.

But the political level did not appreciate the gravity of the situation, insisting on maintaining military presence in Schleswig and at the same time refused more modest German demands of peace. Hence the army was ordered to defend the Dybbøl position "to the last man", and consequently the siege of Dybbøl began.

Communications in the area

The only railways in 1864 in Denmark north of the Kongeå were a line in Sjælland, from Copenhagen to Korsør, and another in northern Jutland, from Århus to the northwest. Any reinforcements for the Danevirke from Copenhagen would have gone by rail to Korsør and thence by ship to Flensburg, taking 2 or 3 days, if not hindered by storm or sea-ice. There was a good railway system in the duchies, but not further north than Flensburg and Husum.

Schleswig town, Flensburg, Sønderborg and Dybbøl were all connected by a road paved with crushed rock, this being the route the army took. The same road continued from Flensburg to Fredericia and Århus and this was the route later taken by the Prussian army when it invaded Jutland.

Events

1863

On November 18 1863 King Christian IX of Denmark decided to sign the November constitution (after the German Confederation disclined former the union constitution of 1855), which declared Schleswig as part of Denmark, what was seen by the German Confederation as a violation of the London Protocol.

In December 24 Saxon and Hanoverian troops marched into Holstein in the name of the German Confederation, and supported by their presence and by the loyalty of the Holsteiners the duke assumed government as "Frederick VIII, Duke of Schleswig-Holstein".

1864

January

For further political events, see History of Schleswig-Holstein.

In January the situation remained tense but without fighting; Danish forces controlled the north bank of the Eider River and German forces the south bank. On January 16 Bismarck issued an ultimatum to Denmark demanding that the November Constitution should be abolished within 48 hours. This was politically impossible, particularly given the short deadline, and the demand was consequently rejected by the Danish government.

All the inland waters (Eider River, Treene, Schlei, and the marshes east of Husum and around the Rheider Au) that the Danes were relying on as defence to guard the flanks of the Dannevirke, were frozen hard and could be crossed easily.

February

At the start of the war, the Danish army consisted of about 38,000 men in 4 divisions. The 8th Brigade consisted of the 9th and 20th Regiments (approximately 1600 soldiers each), which consisted mainly of soldiers from the middle and west and north of Jutland. About 36000 men defended the Dannevirke, a job which it was said would have needed 50000 men to do properly. The 1st Regiment had been changed freom a battalion to a regiment in 1 December 1863. [3]

The Prussian army had 37 battalions, 29 squadrons, and 110 guns, amounting to approximately 38,400 men. The Austrian army had 20 battalions, 10 squadrons, and 48 guns consisting of approximately 23,000 men. During the war the Prussian army was further strengthened with 64 guns and 20,000 men. The supreme commander for the Prussian-Austrian army was Field Marshal Friedrich Graf von Wrangel.

Prussian and Austrian troops cross into Schleswig on February 1, and war became inevitable. The Austrians attacked towards the refortified Dannevirke frontally while the Prussian forces struck the Danish fortifications at Mysunde (on the Schlei coast of Schwansen east of Schleswig town), trying to bypass the Danevirke by crossing the frozen Schlei inlet, but in 6 hours could not take the Danish positions, and retreated.

In the Battle for Kongshøj of February 3, Austrian forces commanded by General Gondrecourt pushed the Danes back to the Dannevirke. The Danish 6th Brigade had an important part. The battle was fought in a snowstorm at -10°C. A Danish fighting against Austrians at Selk and Kongshøj and Saksarmen on 3 February 1864 is described as follows:

The enemy sharpshooters immediately got reinforcement of a whole battalion, which advanced in a column with a music band which blew a storm-march, the batallion's commander followed on a horse, and after that the battalion's standard. Captain Stockfleth ordered his men to fire on the band and the battalion's commander and the standard-bearer. After that the storm-march sounded not so beautiful now that that lacked quite a few voices. The battalion commander's horse was shot under him. He grasped the standard when the standard-bearer fell, and now it went forward again with great strength.This link

A Danish military report[4] dated 11 Feb 1864 describes the incidents near Kongshøj and Vedelspang as follows:

On the 3 February the Regiment's 1st Battalion occupied the Brigade's forward post line while its 2 Battalion stood as a reserve in Bustrup. The company commanders Daue and Steinmann under Major Schack's command increased its main position near Vedelspang while the Stockfleth Company stood between Neder Selck and Alten Mühle as well as the Riise Company behind the dam near Hadeby. During the relief there, 9. Regiment first found its place about 1.30 p.m. and attacked an enemy unit which was coming from Geltorf and Brechendorf. The Stockfleth Company's main position, coming from Vedelspang, had advanced to Kongshøi, and Kastede the same distance behind the Danevirke rampart in front of Bustrup. In Bustrup the shooting was heard about 2 p.m.; Aarsag was in reserve. 2. Bataillon occupied the rampart and covered the withdrawing squads. The enemy pressed intensely in the east towards Hadeby-Noer, but was stopped here and remained fighting in one place until it turned dark. They sent a company to drive away the enemy from Vedelspang, but could not press further on than to towards the north part of the exercise ground.
The regiment's losses in this fighting are: Dead, 1 corporal 1 undercorporal 7 privates; wounded, 2 corporals 3 undercorporals 18 privates; missing 11 privates.
Fredericia 11 February 1864, Scholten, Oberstlieutenant and Regimentscommandeur.

On February 5 the Danish commander-in-chief, lieutenant general Christian Julius De Meza, abandonede the Dannevirke by night to avoid being surrounded and withdrew his army to Flensburg; 600 men were captured or killed, 10 of them frozen to death;[3] he was also forced to abandon important heavy artillery.

The railway from the south to Flensburg was never properly used during this evacuation, and thus the Danish army only evacuated what men and horses could carry or pull by road, leaving behind much artillery, most importantly heavy artillery. In the records are these two stories as to why:-

  • That a waiting train had been instructed to head north at a specific time, which it did, but the army had not yet arrived at the station due to heavy snow.
  • That the artillery was left behind on purpose, to allow a fast escape before the Prussian army noticed anything.
  • But in hindsight other considerations are possible:-
  • That steam railway trains are so noisy that in a silent winter night an unnoticed getaway by railway would be impossible.
  • That the railway to Flensburg was a spur from a system centered in Holstein, and thus its engine's driver and stoker were likeliest Holstein Germans and thus very unwilling to help the Danish Army, given their likely recent clear memories of the First Schleswig War.
  • That the Danish army command had not yet become accustomed to thinking in terms of railways.
Some hours later, the Prussians and Austrians discovered the retreat and started to pursue.
This withdrawal to Als and Dybbøl has gone down in Danish history as one of the worst that Danish soldiers have been exposed to. Some of them compared it to Napoleon's retreat from Moscow. It was northwards in a north gale with driven snow, and most soldiers had had no rest for the last 4 days and nights:image. The march was burdened with artillery guns and supplies carts and had to be as slow as its slowest component. Men and horses had trouble standing. Horses could not carry or pull their loads properly because of the snow and ice; riders had to dismount and lead their horses. Artillery guns and carts overturned. The column of men and horses and vehicles seemed endless. The army had to march from the Danevirke to Flensburg, which took about 14-18 hours. (Schleswig by the east end of the Danevirke is 35 km from Flensburg as the crow flies, but further by road, plus getting from their positions to Schleswig town first.) They also had to fight rearguard against pursuing Prussians and Austrians. Some men in sight of Flensburg and thankful for coming rest were ordered to stop or go back to man checkpoints. Many men were missing at the roll call, and it was thought that that the many Schleswig-men among the soldiers would desert the march on the way and go home; but most of them came in that morning or the next morning.

Near Helligbæk, about 10 kilometers north of Schleswig, pursuing Austrians reached them, and in heavy fighting near Oversø 9the and 20th Regiments of the 8th Brigade lost 600 men dead and injured and captured. On that day 10 Danish soldiers died of hypothermia.

The Prussians crossed the frozen Schlei at Arnis on February 6, defeating the Danes theremap. Near Sankelmark (about 8 kilometers south of Flensburg) pursuing Austrians caught up with the Danish rear party, consisting of the 1st and 11th regiments. The Danes were commanded by Colonel Max Müller. A hard fight where large parts of 1st Regiment were taken prisoner, stopped the Austrians, and the retreat could continue. The Danes lost more than 500 men there. After a short rest and some food and drink in Flensburg, the 8th Brigade had to march to Sønderborg where they were taken by ship to Fredericia; the ship was so loaded that the men could not lie down, and on deck they had no shelter from the winter weather. Other units stayed in Dybbøl; a report says that some were so exhausted on arrival that they lay on the ground in heaps 3 or 4 deep to sleep.

The combatless loss of the Dannevirke, in which the 19th century had a big role in Danish national mythology due to its long history, caused in Denmark a substantial psychological shock, and de Meza as a result had to resign from supreme command. Denmark never again ruled the Dannevirke. The Austrians, under Ludwig Karl Wilhelm von Gablenz, marched north from Flensburg, while the Prussians advanced east on Sønderborg.

On February 18 some Prussian hussars, in the excitement of a cavalry skirmish, crossed the north frontier of Schleswig into Denmark proper and occupied the town of Kolding. An invasion of Denmark itself had not been part of the original programme of the allies. Bismarck determined to use this circumstance to revise the whole situation. He urged upon Austria the necessity for a strong policy, so as to settle once for all not only the question of the duchies but the wider question of the German Confederation; and Austria reluctantly consented to press the war.

The Austrian army decided to stop at the north frontier of Schleswig. Some Prussians moved against Kolding and Vejle. On February 22 Prussian troops attacked the Danish forward line at Dybbøl, pushing them back to the main defence line.

March

In Fredericia Danish 8. Brigade's 20. Regiment were involved in a bigger skirmish: the regiment's 1. Company were captured near Snoghøj (on the mainland near where the Middelfart bridge is now.) The rest of Fredericia's garrison retreated to Fyn.

April

May

June

July

August and after

The preliminaries of a peace treaty were signed on August 1: the King of Denmark renounced to all his rights in the duchies in favour of the Emperor of Austria and the King of Prussia.

In the Treaty of Vienna (October 30 1864) Denmark ceded Schleswig, Holstein and Lauenburg to Prussia and Austria. Denmark was also forced to surrender the enclaves in western Schleswig that were legally part of Denmark proper and not part of Schleswig, but was allowed to keep the island of Ærø (which had been administered as part of Schleswig), the town of Ribe and its surrounding land, and eight parishes from Tyrstrup Herred south of Kolding. As a result of the peace settlement, the land area of the Danish monarchy was decreased by 40% and the total population reduced from 2.6 million to 1.6 million (by about 38.5%) [5]. The Danish frontier had retreated about 250 km as measured from the furthest corner of the Duchy of Lauenburg to the new frontier on the Kongeå river.

When the Danish army returned to Copenhagen after this war, they received no cheering or other public acclaim, unlike on their victorious return to Copenhagen after the First Schleswig War.

Summary

In late 1863 King Frederick VII of Denmark died leaving no sons as he was about to sign a controversial new draft constitution for Denmark and the duchies. The resulting dispute over the succession added to the controversy, and precipitated war between Denmark and an alliance of German states when Christian IX became king and signed the draft constitution.

Denmark pulled its army back to the border between Schleswig and Holstein (Holstein was part of the German Confederation). Most of it fortified itself behind the Danevirke. German troops soon occupied Holstein, which was a German federal state.

The Danish army had smaller guns and an older type of rifle. The Prussian army used the Dreyse needle-gun, a breech-loading rifle that could be loaded while the user was lying down. Since the Danes had to load their older muzzle-loading rifles while standing, they were better targets for the Prussians.

On 5 February 1864, after four days of skirmishing in front of the Danevirke, the Danish army, fearing being outflanked by enemy marching over hard-frozen inland waters, abandoned the Danevirke and retreated to the Dybbøl fort and Als island. Germans pursued the retreat through a blizzard. On 18 April the Prussian army stormed and took Dybbøl in heavy fighting, and on 29 July took Als. This was in effect the end of the war, despite a skirmish on 3 July at Lundby south of Ålborg, and the Danish navy stopping two Prussian naval attempts to break Denmark's naval blockade of the area. The Prussian army advanced far into Denmark proper. On 30 October Denmark signed away Schleswig, Holstein, and Lauenburg except for a few small remnants.

Aftermath

In the Prussian forces' first clash of arms since reorganization, their effectiveness proved clear, something the Austrians ignored, to their cost 18 months later in the Austro-Prussian War. Prussia and Austria took over the respective administration of Schleswig and Holstein under the Gastein Convention of August 14, 1865. About 200.000 Danes came under German rule [6].

The subsequent Peace of Prague, in 1866, confirmed Denmark's cession of the two duchies but promised a plebiscite to decide whether north Schleswig wished to return to Danish rule. This provision was unilaterally set aside by a resolution of Prussia and Austria in 1878.

The Second Schleswig War shocked Denmark out of any idea of using war as a political tool. Danish forces were not involved in war outside their frontiers until the 1999 NATO bombing of the Federal Republic of Yugoslavia. It became clear that against the might of Germany, Denmark could not assert its survival with own arms; this played a crucial role in the "adjustment policy" and later "Cooperation policy" during the Nazi-German occupation in World War II.

Since Sweden (and Norway) refused to come to Denmark's rescue although the Swedish king promised troops, this put an end to any dreams of political Scandinavism. As a consequence, the pan-Scandinavian movement after this year focused on literature and language, rather than politics.

There is little doubt that the defeat was a traumatising event for Denmark, which lost approximately a quarter of its population and some of the richest parts of the country; but some of the most "ethnically Danish" parts of this "lost land" were returned to Denmark by the Treaty of Versailles.

From a Danish perspective, perhaps the most grievous consequence of the defeat was that thousands of Danes living in the ceded lands were conscripted into the German army in World War I and suffered huge casualties on the Western Front. This is still (though waning in time as the children of the conscripted men are dying out) a cause of resentment among many families in the southern parts of Jutland and the direct reason why a German offer of a joint 100 years anniversary in 1966 was rejected.

In Germany the Battle of Dybbøl and the Second War of Schleswig have largely vanished out of the consciousness of the German public.

In literature

Danish author Herman Bang wrote about the war and its effects on the island of Als in his novel Tine, published in 1889. The book has been translated into many languages, including English, and is considered to be an example of an impressionist novel.
