context_page_description: The Swedish invasion of the Holy Roman Empire or the Swedish Intervention in the Thirty Years' War is a historically accepted division of the Thirty Years' War. It was a military conflict that took place between 1630 and 1635, during the course of the Thirty Years' War. It was a major turning point of the war: the Protestant cause, previously on the verge of defeat, won several major victories and changed the direction of the War. The Habsburg-Catholic coalition, previously in the ascendant, was significantly weakened as a result of the gains the Protestant cause made. It is often considered to be an independent conflict by most historians.
  After several attempts by the Holy Roman Empire to prevent and contain the spread of Protestantism in Europe, King Gustav II Adolf of Sweden led an invasion of the Holy Roman Empire. Although he was killed in battle at Lützen, southwest of Leipzig, the Swedish armies managed to successfully defeat their Catholic enemies and established Sweden as one of the great powers of Europe for the next 100 years.
context_section_description: The battle started in the middle of the day and lasted over six hours. The first two hours consisted of an exchange of artillery fire. This was followed by an Imperial attack with cavalry from both wings to both ends of the Protestant line. The cavalry attack routed the Saxon troops on the Swedish left flank. The imperial army then conducted a general attack to exploit the exposed left flank. The Swedes repositioned their second line to cover the left flank and counterattacked with their cavalry to both imperial flanks. The attack on the Imperial left was led personally by Gustavus Adolphus, capturing the Imperial artillery and enveloping the Imperial left flank. The Swedes now had much greater weight of fire from their artillery, infantry, and the captured Imperial artillery. The Imperial line became disorganized under the heavy fire and was enveloped. The Imperial line collapsed and over 80% of Imperial forces were killed or captured.
  The combined Swedish-Saxon forces were to the north of Leipzig centred around hamlet of Podelwitz, facing southwest toward Breitenfeld and Leipzig. The battle began around mid-day, with a two-hour exchange of artillery fire, during which the Swedes demonstrated firepower in a rate of fire of three to five volleys to one Imperial volley. Gustavus had lightened his artillery park, and each colonel had four highly mobile, rapid firing, copper-cast three pounders, the cream of Sweden's metallurgical industry. When the artillery fire ceased, Pappenheim's Black Cuirassiers charged without orders, attempting to turn the Swedish right. Instead, their attack fell between Johan Banér's line and the Swedish reserves. They attacked with a caracole and were driven back, repeating the maneuver six more times to little effect. The small companies of musketeers dispersed between the squadrons of horse fired a salvo at point blank range, disrupting the charge of the Imperialist cuirassier and allowing the Swedish cavalry to counterattack at an advantage.  The same tactics worked an hour or so later when the imperial cavalry charged the Swedish left flank. Following the rebuff of the seventh assault, General Banér sallied forth with both his light (Finnish and West Gaetlanders) and heavy cavalry (Smalanders and East Gaetlanders). Banér's cavalry had been taught to deliver its impact with the saber, not to caracole with the hard-to-aim pistols or carbines, forcing Pappenheim and his cavalry quit the field in disarray, retreating 15 miles northwest to Halle.
  During the charges of the Cuirassiers, Tilly's infantry had remained stationary, but then the cavalry on his right charged the Saxon cavalry and routed it towards Eilenburg. There may have been confusion in the imperial command at seeing Pappenheim's charge; in their assessment of the battle, military historians have wondered if Pappenheim precipitated an attempted double envelopment, or if he followed Tilly's preconceived plan. At any rate, recognizing an opportunity, Tilly sent the majority of his infantry against the remaining Saxon forces in an oblique march diagonally across his front.
  Tilly ordered his infantry to march ahead diagonally to the right, concentrating his forces on the weaker Saxon flank. The entire Saxon force was routed, leaving the Swedish left flank exposed. Before the Imperial forces could regroup and change face towards the Swedes, the commander of the Swedish Left, Marshal Gustav Horn, refused his line and counter-attacked before the tercios could regroup and change face.
  With the Imperial forces engaged, the Swedish right and centre pivoted on the refused angle, bringing them in line with Horn. Banér's cavalry, under the direct command of Gustavus Adolphus, attacked across the former front to strike the Imperial right and capture their artillery. As Tilly's men came under fire from their own captured batteries, the Swedish cannon, under Lennart Torstensson, rotated, catching the tercios in a crossfire.
  After several hours of punishment, nearing sunset, the Catholic line finally broke. Tilly and Pappenheim were both wounded, tho
