The Battle of Saint Quentin took place from August 10 to August 23, 1557, during the Habsburg-Valois Wars. It was fought between the forces of King Philip II of Spain and the French army led by King Henry II of France. The battle was significant for its strategic location near the town of Saint Quentin in northern France, which was a key point for both sides. The Spanish forces, numbering around 30,000, achieved a decisive victory over the French, who were outnumbered and poorly coordinated. This battle solidified Spanish dominance in the region and marked a turning point in the ongoing conflict between the two powers.
