Question: The Battle of Bov was the first battle of what military conflict between southern Denmark and northern Germany?
Context: The First Battle of Champagne (French: "1ère Bataille de Champagne" ) was fought from 20 December 1914 – 17 March 1915 in World War I in the Champagne region of France and was the second offensive by the Allies against the Germans since mobile warfare had ended after the First Battle of Ypres in Flanders(19 October – 22 November 1914).  The battle was fought by the French Fourth Army and the German 3rd Army.  The offensive was part of a strategy by the French army to attack the Noyon Salient, a large bulge in the new Western Front, which ran from Switzerland to the North Sea.  The First Battle of Artois began on the northern flank of the salient on 17 December and the offensive against the southern flank in Champagne began three days later. Low German or Low Saxon (Low German Plattdütsch, Plattdüütsch, Plattdütsk, Nedderdüütsch; Platduuts, Nedderduuts ; German: "Plattdeutsch, Niederdeutsch" ; Dutch: "Nedersaksisch" or "Nederduits" ) is a West Germanic language spoken mainly in northern Germany and the eastern part of the Netherlands.  It is also spoken to a lesser extent in the German diaspora worldwide (called the Plautdietsch), by ethnic Frisians wherever Friso-Saxon dialects are spoken, and in Southern Denmark. The First Schleswig War (German: "Schleswig-Holsteinischer Krieg" ) or Three Years' War (Danish: "Treårskrigen" ) was the first round of military conflict in southern Denmark and northern Germany rooted in the Schleswig-Holstein Question, contesting the issue of who should control the Duchies of Schleswig and Holstein.  The war, which lasted from 1848 to 1851, also involved troops from Prussia and Sweden.  Ultimately, under international pressure, the Prussians had to withdraw their forces.  As a result, the war ended in a Danish victory over the rebels.  A second conflict, the Second Schleswig War, erupted in 1864. The Battle of Changshao was a military conflict between Qi and Lu, two major principality states in Shandong Peninsula during the Spring and Autumn Period of Zhou dynasty.  The battle happened in the January (lunar calendar) of 684 BC at Changshao.  Lu claimed the victory under the lead of general Cao Gui (曹刿).  This battle is described in detail by Zuo Qiuming in his "Spring and Autumn Commentary of Zuo", but it is not mentioned in Sima Qian's book of "Shi Ji".  This battle is considered as a classic example of winning by good military strategies, and the widely-used Chengyu of "Yi Gu Zuo Qi" was derived from this battle. The Battle of Bov (German : Bau) was a battle between troops fighting for Schleswig-Holstein, and those for Denmark, which happened on April 9, 1848 in the area of Flensborg in Denmark, during the First Schleswig War.  Denmark won the engagement.  It was the first battle of the First Schleswig War. Old Saxon, also known as Old Low German, was a Germanic language and the earliest recorded form of Low German (spoken nowadays in Northern Germany, the northeastern Netherlands, southern Denmark, the Americas and parts of Eastern Europe).  It is a West Germanic language, closely related to the Anglo-Frisian languages.  It has been documented from the 8th century until the 12th century, when it gradually evolved into Middle Low German.  It was spoken throughout modern northwestern Germany, primarily in the coastal regions and in the eastern Netherlands by Saxons, a Germanic tribe who inhabited the region of Saxony.  It partially shares Anglo-Frisian's (Old Frisian, Old English) Ingvaeonic nasal spirant law which sets it apart from Low Franconian and Irminonic languages, such as Dutch, Luxembourgish and German. The Battle of Ticinus was a battle of the Second Punic War fought between the Carthaginian forces of Hannibal and the Romans under Publius Cornelius Scipio in November 218 BC.  The battle took place in the flat country of Pavia county on the right bank of the Ticino River, not far north from its confluence (from the north) with the Po River.  The battle is named from the river, not the nearby contemporaneous settlement of Ticinum (today's Pavia).  Although the precise location is not known, it is generally accepted that a settlement known today as Vigevano is mentioned in Livy's text and that Scipio's camp was to the south at Gambolo, whose coordinates are given on the map.  The conflict would have been west of there.  It was the first battle of the war against the Romans that was fought on Italian soil and the first battle of the war to employ legion-sized forces.  Its loss by the Romans, and the temporary disablement of Scipio's command, set the stage for the Roman disaster at the Battle of Trebbia in December. The Siege of Golubac (Hungarian: "Galambóc" ) was a military conflict between the Hungarian–Wallachian–Lithuanian alliance and the Ottoman Empire in May 1428.  This siege was the first battle in the Hungarian military history, when the Hungarian army used significant artillery.  However, they could not capture Golubac as it was defeated by the Ottoman main army, led by Sultan Murad II.  After the battle, most of Serbia and Bosnia was conquered by the Ottoman Army.
