The Battle of Nördlingen took place on 6 September 1634 during the Thirty Years' War. A combined Imperial-Spanish force inflicted a crushing defeat on the Swedish-German army.
The Battle of Rocroi, fought on 19 May 1643, was a major engagement of the Thirty Years' War between a French army, led by the 21-year-old Duke of Enghien and Spanish forces under General Francisco de Melo only five days after the accession of Louis XIV to the throne of France after his father's death. Rocroi shattered the myth of invincibility of the Spanish Tercios, the terrifying infantry units that had dominated European battlefields for the previous 120 years. The battle is therefore often considered to mark the end of Spanish military greatness and the beginning of French hegemony in Europe during the 17th century. After Rocroi, the Spanish progressively transformed the tercio system incorporating more of the line infantry doctrine used by the French over time.

The Battle of Kallo was a major field battle fought from 20 to 21 June 1638 in and around the forts of Kallo and Verrebroek, located on the left bank of the Scheldt river, near Antwerp, during the second phase of the Eighty Years' War. Following the symbolic recovery of Breda during the 1637 campaign, the Dutch Republic agreed with the French Crown, with whom it had allied in 1635, to besiege a major city in the Spanish Netherlands during the 1638 campaign. The commander of the Dutch States Army, Frederick Henry of Orange, planned an approach over Antwerp from the two sides of the Scheldt. After marching the army, Frederick Henry transferred 50 barges to Count William of Nassau-Siegen and he was left entrusted to land in the Spanish-controlled Waasland region, west of Antwerp, to seize the forts of Kallo and Verrebroek, along with several other key fortifications, to invest Antwerp from the west. In the meantime, Frederick Henry would advance on the opposite bank to complete the blockade of the city while the armies of France invaded the Spanish Netherlands from the south to oblige the Spanish Army of Flanders to divide its forces.

The Army of Flanders was a multinational army in the service of the kings of Spain that was based in the Spanish Netherlands during the 16th to 18th centuries. It was notable for being the longest-serving army of the period, being in continuous service from 1567 until its disestablishment in 1706 and taking part in numerous pivotal battles of the Dutch Revolt (1566–1609) and the Thirty Years' War (1618–1648). Because it employed or pioneered many developing military concepts more reminiscent of later military units, enjoying permanent, standing regiments (tercios), barracks, military hospitals and rest homes long before they were adopted in most of Europe, the Army of Flanders has been considered the world's de facto first modern professional standing army. Sustained at huge cost and at significant distances from Spain via the Spanish Road, the Army of Flanders also became infamous for successive mutinies and its ill-disciplined activity on and off the battlefield, including the Sack of Antwerp in 1576.

Johann Philipp Kratz von Scharffenstein was a German nobleman and field marshal, who fought during the course of the Thirty Years' War. He served with distinction in forces of both the Catholic League and Holy Roman Empire. His poor relationship with the Imperial generalissimo Albrecht von Wallenstein frustrated his plan of becoming the supreme commander of the League's forces. Embittered by this he defected to Sweden, where he attained the rank of field marshal. He was captured at the Battle of Nördlingen in 1634 and executed for treason a year later.
