Before daybreak the Swedish army broke camp and made preparations to cross the river. The Swedes had 2,000 infantry and 6,000 cavalry at their disposal; their Danish opponents had more than 5,000 infantry, 6,000 cavalry, in addition to a few hundred
Dutch sailors—in all, about 13,000 men. Under the cover of a moonless night, between 04:00 and 05:30, the entire Swedish force successfully crossed the river and reached the southern bank without alarming the Danes. The Swedes planned to attack the sleeping Danish camp with cavalry from the southeast. Reconnaissance patrols reported that the ground between the two armies was unsuitable for mounted troops, so King Charles XI and his
generals gathered to discuss the new situation. Most advisers pointed out that it would be foolish to attack by foot as the Danish army possessed much more infantry and the Swedish main strength lay in its cavalry. Additionally, the Swedes would likely lose the element of surprise during the long march towards the Danish camp. The king was eager to attack at once, but was swayed by his advisers. He ordered the troops to advance towards the hills just outside the north wall of Lund, to seize a tactical advantage. The hills would mean better terrain for the cavalry and the town itself would cover the Swedish southern flank. By then the Danes had woken, and soon recognised the Swedish intentions. The Danes quickly broke camp and started to race the Swedes for control of the hills. The first skirmish was between the Swedish right wing and the Danish left wing, and ended in a draw. However, the hills were secured under Swedish control, and the Danes were pushed to the east. The main battle began at 09:00, at sunrise. The front now stretched one kilometer from north to south, with the Danes to the east and the Swedes to the west. The Danish army was supported by 56
cannon of various calibers, while the Swedes brought only eight six-pounders and four three-pounders. Once the fighting commenced, Charles XI personally led a flanking maneuver to overwhelm the Danish left flank. During the fighting, the Danish commander
Carl von Arensdorff was badly wounded, and the entire left wing was forced to retreat at 10:00, severely crippling the Danish army. Von Arensdorff would later die from
gangrene after amputation. Charles XI and Field Marshal
Simon Grundel Helmfelt used their cavalry to pursue fleeing Danish troops and cut down any who lagged behind. The pursuit continued for eight kilometers, right up to the river. Some officers at the Danish camp attempted to ward off the Swedes, but many Danes were forced onto the ice. The ice did not hold, and a great number of the remaining Danish left wing drowned. While the Danish left wing fled, the right wing pushed the Swedes back until the Swedish left wing scattered with its commander
lieutenant general Johan Galle killed. With the absence of Danish King Christian V and with General Arensdorff wounded,
Friedrich von Arensdorff, the general's brother, had assumed command of the Danish army. The Danish front was now facing south and the Swedish forces found themselves under constant attack with their backs against the town wall. The situation for the Swedes was desperate, as there had been no sign of the king, the Household cavalry, or the Field Marshal for hours. The Swedes were also greatly outnumbered, with approximately 1,400 infantry and 2,500 cavalry, as the Danes approximately counted 4,500 infantry and 2,100 cavalry. However, instead of forcing the attack, Friedrich von Arensdorff ordered the army to regroup at noon, halting the battle. At the river, the Swedish king was contemplating his next move. Available intelligence from the town was scarce, and suggested that the whole Danish army was on the run. Although he was tempted to rout the fleeing Danish cavalry all the way to
Landskrona, he decided to return to his army instead. The battle at Lund renewed, and the Swedes were forced back once more. At sunset (about 15:00) the Swedish king returned from the north with his cavalry, combined with some cavalry units from the scattered Swedish left wing. He decided to try to circle the Danish army to the west to join the remains of the Swedish center. Danish commander Arensdorff made the decision to halt the offensive on the Swedish center and instead tend to the enemy cavalry in the northwest. Charles XI, two generals, and three guards broke through the Danish lines to join the diminished Swedish center. While Arensdorff was still attacking the cavalry in the north, the return of the Swedish king inspired the exhausted troops, who attacked the Danish forces in the back. Though the Danes still outnumbered the Swedes, by approximately 4,500 to 4,000, Arensdorff had lost the initiative and after half an hour his army disintegrated. Charles XI wanted to clear the field of Danish soldiers. The remaining Danish cavalry quickly disappeared into the night. Although Danish General Siegwert von Bibow protected the infantry retreat, many of the Danes were massacred until Field Marshal Helmfelt ordered the killing to stop and the surrendering Danish soldiers were spared. At 17:00 a ceasefire was sounded. ==Aftermath==
