1515 was an unusual year, the year of the death of Louis XII, and at the same time, the French and Switzerland turned against each other, and hired German mercenaries, united with the Italians, to defeat the invincible Swiss spearmen, forcing the Swiss League to declare permanent neutrality.

The Battle of Marignano, which changed history, announced the fall of the Swiss spear formation and symbolized the rise of French artillery. The Swiss lost 11,000 men in World War I and withdrew from the mainstream European battlefield stage, becoming a supporting actor.

Of course, in that war, the French did not face the main force of the entire Swiss army, but only the allied forces in eastern Switzerland. The western cantons of Switzerland, led by the canton of Bern, were bought by France with 700,000 gold coins because of their proximity to France, and a total of 12,000 Swiss mercenaries withdrew from the battlefield, leaving only 20,000 eastern Swiss mercenaries to face off against the French army, and were defeated in World War I, losing the prestige of Swiss mercenaries.

However, because of Marin's crossing, this war is doomed to be impossible. Because, France and Switzerland have not turned their backs. Under Marin's intervention, the Habsburgs, the weak chicken, actually occupied half of Switzerland. As a result, the Swiss could not be as arrogant as they had been in history, and they did not dare to turn against France. It even had to rely on the power of France to seek to expel the Habsburg army in Switzerland.

Since the return of 10,000 Swiss mercenaries to the Swiss battlefield, the balance of power on the Swiss battlefield has changed. Although the Habsburg army was larger, it was really no match for Switzerland in field warfare. Even a famous general like Frenzberg could not compete with the Swiss Resistance because his soldiers were too weak to fight.

The 15,000 horses of the headquarters trained by Frenzberg himself are all trained in the North Sea Country, and their combat effectiveness is naturally not under the Swiss mercenaries. However, the other more than half of the soldiers and horses were ordinary German mercenaries who had been collected and hired, and their combat effectiveness and fighting will were not very strong, and it was difficult to compete with the Swiss. So, despite the fact that there were more soldiers, the Habsburg army had to fall to the bottom and was forced to go on the defensive.

Fortunately, Marin took good care of the Habsburgs, provided a large amount of cement, and built dozens of cement fortresses on various main roads in the Swiss mountains, which were easy to defend and difficult to attack. In addition, the defenders were equipped with a number of arquebuses, which greatly increased the fort's defensive capabilities.

At this point, the weakness of the Swiss was exposed - the Swiss mercenaries mainly used spears, and although they were strong in the field, they were very poor in attacking fortifications.

The dozens of cement fortresses that Marin helped the Habsburgs build were easy to defend and difficult to attack on the east-west arteries of the Swiss mountains. Therefore, even if the commander of the Swiss Resistance is very capable, there is nothing he can do about it. It can't be helped, who called Switzerland full of mountains? Find a few passes in the valley and build a cement fortress that is larger than the devil's turret, which can withstand thousands of troops and horses, leaving the fierce Swiss spearmen in the field helpless.

In fact, the previous "Battle of Lübeck", which was defeated by Swiss mercenaries, has exposed the weakness of Swiss mercenaries - fear of firearms.

But the Swiss still didn't pay attention, and in that battle, Marin used too many means to make the Swiss mercenaries lose a little confused, but they didn't pay attention to the restraint of firearms against the Swiss spearmen.

After all, Swiss mercenaries are just a group of mountain people, who don't know a few big words, and they don't know what "restraint of arms" is. Just like the Swiss spearmen, it was by relying on the spearmen to overcome the advantage of the plate knights that they defeated and killed the Duke of Burgundy "Charles the Daring", who was dominated by the plate knights, which became famous in Europe.

From then on, the Swiss began to be confident that their spearmen could take out any opponent. Unbeknownst to them, muskets and artillery were the natural enemies of the Swiss spearmen......

Historically, the Swiss mercenaries have suffered two major setbacks – one was the Battle of Marignano in 1515, in which French artillery fired a cluster of 70 guns to defeat the Swiss spear charge.

Another battle that made the Swiss completely withdraw from the stage of history was that Frenzberg, who was originally known as the "father of German mercenaries" in history, led German mercenaries to repel the charge of Swiss spearmen with dense arquebuses in the Battle of Bicoca, and won the final victory. Subsequently, in the Battle of Pavia in 1525, German mercenaries, who used muskets in large numbers, directly defeated the French and Swiss mercenaries (the eastern Swiss mercenaries had already been crippled in the north at the Battle of Marignano), and even captured the French king François I.

After the Battle of Pavia, the Swiss mercenaries completely withdrew from the mercenary scene. Because, German mercenaries replaced them. The German mercenaries showed greater combat effectiveness and cheaper commissions (in fact, the Swiss had too high commissions), which naturally replaced the Swiss mercenaries and robbed them of their business......

……

But now, in a different time and space, Swiss mercenaries have not yet withdrawn from the stage of history. Because, they haven't been devastated. Even after the defeat of the Swiss at the Battle of Lübeck, Marin did not kill a few Swiss mercenaries. So, the roots of the Swiss are still there. Coupled with Marin's penchant for intrigue, the Swiss have always believed that they were losing by intrigue rather than tactical tactics.

For example, now, with more than 20,000 Swiss spearmen, Ziggy is thinking about how to attack the more than 30,000 Habsburg troops guarding the fortress......

Strange, right? 27,000 Swiss spearmen thought about how to break through the fortress guarded by 35,000 Habsburg troops. Obviously, the Swiss are not generally strong in self-confidence.

But no matter how fierce they were in the wilderness, the Swiss were helpless in the face of concrete fortresses. Then they thought of French artillery......

Originally, King Louis XII of France intended to send a large army to help Switzerland defeat and expel the Habsburg army in Switzerland after the autumn harvest.

Unfortunately, because the eastern and northeastern parts of France suffered from the autumn harvest rains, there was a shortage of military rations. Thus, the plans of the French to help the Swiss attack the Habsburg army were put on hold. Louis XII could only reluctantly say - next year.

Moreover, Louis XII also discovered that it seems that the German mercenary general Gudendorff, who was forced to accept his own employment, did not listen to his own commands. For example, Louis XII asked Goodendorff to lead a large army to storm the Müstair Valley, and took advantage of the situation to attack the Swiss region of Graubünden and attack the army of Frenzberg from behind......

As a result, Gudendorff's army did not work hard, and it seemed that it was attacking, but after a few months of attacking, the loss of soldiers and horses was only a few hundred (in fact, the hundreds of people lost were deliberately hidden by Gudendorff), which is obviously really good......

It wasn't just Louis XII who saw this, but even Ziggy. This also made Ziger realize that this year the French could not be counted on and had to rely on themselves.

And the Swiss don't want to wait until the end of the year, who knows what will happen at the end of the year? After all, the French and Spanish armies were facing off in Naples and might not have time to support Switzerland.

Therefore, Ziegy finally made a decision - to borrow artillery from the French, in order to use artillery to blast down the fortresses on the dozens of important roads, and clear the way for the Swiss army to march eastward.

Ziggy had fought many battles with the French and knew how powerful the artillery was. If you have more artillery, you should be able to break through the small fortresses on the mountain roads. When the time comes, the road to the east will be opened, and Ziggy will be able to walk behind the enemy with his men and horses, cutting off their supply lines.

As for the enemy going out of the city to obstruct it? When were Swiss mercenaries afraid of field battles?
