- Lucas: We’ve spent a lot of time talking about the shadows cast by the Third Reich, but before the swastika, there was the black eagle, and before that, there was the relentless, disciplined march of Frederick the Great. It’s easy to view the 18th century as a distant prelude to modern nationalism, but for Prussia, it was a period of existential improvisation where survival depended on winning every single battle. Lucas: By 1757, Frederick had already proven himself a military prodigy, taking Silesia from Austria with shocking speed and making himself the arbiter of Central European politics. He was young, brilliant, and utterly convinced of his own tactical genius, believing that the Prussian army could fight multiple wars simultaneously without breaking. Luna: So he was basically betting the entire kingdom on his ability to keep winning? Lucas: Exactly. And that bet came due in June of 1757, when he marched into Bohemia to capture Prague. He had defeated the Austrians under Prince Charles earlier that spring, so he assumed the path to Vienna was clear. But history has a way of punishing arrogance, especially when it’s armored in steel. Lucas: The problem wasn't just the enemy; it was the ground. After the initial victory at Prague, Frederick found himself besieged by a new Austrian force led by Marshal Leopold von Daun, a commander who was far more cautious and experienced than his predecessor. Daun didn't attack head-on immediately; he waited, maneuvering to cut off Frederick’s supply lines and forcing the King to make a move he didn't want to make. Luna: And that’s when the Battle of Kolin happened? Lucas: It was. On June 18, 1757, Frederick decided to break the siege and drive Daun out of Bohemia once and for all. He launched a massive assault against the Austrian positions on the Rosemberg Heights, a ridge that offered commanding views and defensive advantages. What followed was not a clean victory, but a grinding, bloody disaster that would shatter the myth of Prussian invincibility. Lucas: Frederick attacked with overwhelming numerical superiority, throwing wave after wave of infantry against the Austrian right flank. For hours, the Prussians fought with their usual discipline, but they were fighting uphill, against entrenched artillery, and into a killing zone designed by Daun. The Austrians held firm, and eventually, the Prussian momentum stalled completely. Luna: I can imagine the sheer exhaustion of fighting uphill against entrenched guns. Lucas: It was brutal. The Prussian cavalry charges were repulsed with heavy losses, and the infantry, despite their reputation, began to falter under the sustained fire. Daun saw the hesitation in Frederick’s lines and ordered a counterattack that broke the Prussian center. The order to retreat was given late, and the withdrawal turned into a chaotic rout, with soldiers dropping their weapons to flee toward the border. Lucas: Frederick lost nearly a quarter of his army, roughly 14,000 men killed or captured, while Daun suffered fewer casualties. More importantly, Frederick was forced to abandon his siege of Prague and retreat back into Saxony, leaving Bohemia in Austrian hands. It was the first major defeat of his career, and it sent shockwaves through the royal courts of Europe. Luna: That must have been devastating for his confidence. Lucas: Devastating isn’t the word; it was traumatic. Frederick never quite recovered his psychological edge after Kolin. He wrote to his sister, Princess Wilhelmine, saying that if God had not protected him, he would have fallen into the hands of the enemy. That level of vulnerability was alien to him, and it changed how he approached warfare forever. Lucas: But the political consequences were even more severe. Before Kolin, some powers had hesitated to join the war against Prussia, fearing his brilliance. After Kolin, the French saw an opening. They signed the Second Treaty of Versailles with Austria, pledging financial support and troops to crush Prussia. The 'Diplomatic Revolution' was underway, isolating Frederick completely. Luna: So one bad day effectively brought France and Russia into the war? Lucas: It accelerated it massively. Within months, Russia joined the coalition, bringing its vast manpower to bear on East Prussia. Frederick now faced enemies on three fronts: Austria to the south, France to the west, and Russia to the east. He had gone from being a regional aggressor to a nation under existential threat. Lucas: Yet, Frederick refused to surrender. He retreated to Saxony, regrouped his battered forces, and prepared for another year of fighting. He knew he couldn't win a war of attrition against such numbers, so he doubled down on mobility and surprise, hoping to defeat each enemy individually before they could coordinate. It was a gamble that would define the next seven years. Luna: He basically had to keep winning just to stay alive. Lucas: Precisely. And that pressure cooker environment is what led to his later masterpieces, like Rossbach and Leuthen, where he annihilated larger French and Austrian armies through sheer tactical audacity. But those victories were built on the ashes of Kolin. Without that disaster, he might have remained confident, but he wouldn't have become the desperate, calculating survivor that history remembers. Lucas: The Battle of Kolin also highlighted the limitations of linear tactics. The rigid formations that worked so well on the flat plains of Brandenburg struggled in the broken terrain of Bohemia. Daun proved that patience and defensive positioning could neutralize Frederick’s offensive power, a lesson that other commanders quickly learned. Luna: Did Daun get credit for that victory at the time? Lucas: Not nearly enough. In Vienna, Maria Theresa celebrated the recovery of Prague, but Daun was viewed with suspicion by the court faction, who blamed him for not pursuing Frederick more aggressively after the battle. He was replaced shortly after, showing that even successful generals could be victims of political intrigue in the Habsburg court. Lucas: Frederick, meanwhile, used the defeat to reform his officer corps and refine his strategic thinking. He realized that he could no longer rely on quick victories. He had to prepare for a long war, which meant securing alliances and managing his economy carefully, though the latter was always a struggle for Prussia. Luna: It sounds like a harsh teacher. Lucas: It was. And it set the stage for the Seven Years' War, which historians sometimes call the first global war, fought in Europe, North America, India, and at sea. For Germany, it was a painful adolescence, forging a national identity through fire and blood, centered around the figure of the King who refused to fall. Lucas: If you've been stepping into history with us episode by episode, you know that these stories aren't just about dates and battles, but about the human capacity to endure. Our work here is independent, driven by curiosity rather than algorithms, and it relies entirely on the support of listeners like you to remain ad-free and continue digging into these complex narratives. Luna: It really helps keep the research deep and the storytelling honest. Lucas: Exactly. If you’d like to support that mission, you can find us on buy me a coffee dot com slash fexingo. It’s a simple way to say thanks and help us bring more of these conversations to light. Luna: We appreciate every bit of help in keeping the archives open. Lucas: Back to the battlefield. After retreating from Kolin, Frederick’s situation looked dire, but he had one ace left to play in the west. While the main coalition forces massed in the east and south, a French army under the Duc de Richelieu was advancing toward Saxony, aiming to link up with the Austrians and squeeze Prussia into submission. Lucas: Frederick responded with a daring maneuver. Instead of waiting for the French, he moved rapidly to intercept them, leading to the Battle of Rosbach in November 1757. This engagement would become legendary, a perfect example of Frederick’s tactical brilliance, but it was only possible because he had survived the humiliation of Kolin and managed to hold his core territory together. Luna: So Kolin was the crucible that forged Rosbach. Lucas: In many ways, yes. It stripped away his illusions and forced him to adapt. Without Kolin, there is no Rosbach, no Leuthen, and perhaps no modern Prussia. It serves as a reminder that failure is often the precursor to the most significant turning points in history. Lucas: As we look back at the 18th century, it’s worth noting how fragile these states were. A single battle could redraw maps, topple dynasties, and shift the balance of power across continents. The story of Germany is deeply tied to these moments of crisis and resilience. Luna: It makes you wonder what happens when the unexpected breaks the plan. Lucas: That’s the question, isn’t it? When the plan fails, do you collapse, or do you rebuild? Frederick chose to rebuild, and in doing so, he laid the groundwork for the German Empire that would emerge centuries later. The road was paved with defeats as much as victories.
