The birth of Prince Marin filled Zygmunt I's heart with excitement and fighting spirit.

"It looks like I have to snatch the Duchy of Mazovia for my son!"

The Duchy of Mazovia now does not have an official duke, but the wife of the former duke Conrad III, Anna. Regency of Radziwiu. Anna. Stanislav, the eldest son of Radzivius and former Duke Conrad III of Mazovia, is now only 11 years old, a year older than Caesar, and not yet old enough to be crowned duke. So, for the time being, it was under its regent.

And Anna. Radziviu is not small - her father Micarolios. Radziwius, a former prime minister of Lithuania, was also a former subordinate of Zygmunt I.

Micarroyos. Radziwiu was once a powerful lord and general in Lithuania, commanding an army of up to 10,000 men. At the beginning, he did not have a good relationship with Sigmunt I, who had just ascended the throne, and even relied on his strength to bully the new king. Therefore, after Sigismunt I ascended the throne, he did not live in Vilnius, the capital of Lithuania, like his brother Alexander, but returned to Krakow, Poland.

However, Micarolios. Radziwiu died in 1509. Had it not been for his death, Zygmunt I would not have dared to touch the principality of Mazovia, which was regent for his daughter Anna.

In fact, Anna. Radziwiu is not strong. Although she is the regent of the Duchy of Mazovia, the power is in the hands of the ministers. Before, it was also decided by her ministers who were strong against the Jagiellonian royal family. However, she has to carry this pot, who calls her the regent.

……

Moreover, Zygmunt I actually had the ambition to annex the Duchy of Mazovia for a long time. Historically, he annexed the Duchy of Mazovia in 1529. However, this was mainly due to the fact that Poland had fought a great war with the Teutonic states in 1525, forcing the Teutonic Knights to submit to their knees. After solving the great problem of the Teutonic state, he had the energy to take action against the Duchy of Mazovia, which did not obey the orders.

But in this time and space, the situation is different. With Marin's support, Prince Philip of the Lamarck family became Grand Master of the Teutonic kingdom and pursued a friendly policy with Poland. Therefore, Poland (including Lithuania) has been at peace with the Teutonic Knights for many years.

In this way, King Zygmunt I of Poland had the strength to clean up the opposition in his country......

It just so happened that the Duchy of Mazovia, because of the stupidity and short-sightedness of its internal vassals, was so desperate that it was loaded on the muzzle of Zygmunt I. Zygmunt I was worried that there was no excuse, how could he miss this great opportunity? So, without hesitation, he mobilized a large army and stormed the Duchy of Mazovia......

In fact, Zygmunt I was able to mobilize more than 15,000 men, but doubled his army. However, that kind of scale is what only needs to be dispatched to fight a national war. And the size of 15,000 people is sending a signal to the outside world - this is a personal feud between the royal family and the Duchy of Mazovia, so don't interfere......

Therefore, Zygmunt I did not look for helpers, but only dispatched the Jagiellonian royal family's own soldiers and horses. In this way, the nobles in Poland had no reason to send troops to help the Duchy of Mazovia.

Of course, the Duchy of Mazovia was not bad. Although they did not have an army of 15,000, they also made up an army of 13,000, and it looked like they were evenly divided.

But Zygmunt I knew that his side had the upper hand. Because, he has a killer weapon in his hand - hussars......

This was suggested to him by Marin a few years earlier when he was married, and at Marin's suggestion, Sigismunt I recruited 4,000 uninherited knights from Polish and Lithuanian noble families close to the Jagiellonian royal family to form 20 squadrons of Polish hussars.

Its tactics, and even its equipment, were exactly as Marlin suggested. Hussars abandoned their heavy horse armor for the sake of flexibility. And in order to facilitate the cavalry to get on the horse, the plate armor pants were abandoned, and only the upper body plate armor and helmet were retained.

As for the weapons, they also switched to spring-loaded cavalry guns supplied by the North Sea State instead of bulky oak cavalry rifles.

After several years of training, the combat effectiveness of the Polish hussars in 20 squadrons with a total of 4,000 people is already considerable. The only thing lacking is actual combat experience.

So, this time to attack the Duchy of Mazovia, Zygmunt I took out the secret weapon of hussars......

……

In order to lure the army of the Duchy of Mazovia out of the city for a decisive battle and avoid a strong battle, the army led by Zygmunt I deliberately hid it at first and fought evenly with the army of the Duchy of Mazovia.

It just so happened that the son of Zygmunt I was born, and the army of the Jagiellonian royal family simply set up camp in the southern part of the Duchy of Mazovia and stopped the attack.

And Zygmunt I, after accompanying his wife and children for a few days, also hurried back to the battlefield......

……

Because the army of the Jagiellonian royal family did not move, the army of the Duchy of Mazovia was a little unstable and took the initiative to provoke. Prince Zygmunt deliberately suffered a small defeat, which boosted the self-confidence of the army of the Duchy of Mazovia.

Then, Zygmunt I proposed that because of the birth of Prince Marin, he had no intention of fighting a war of attrition with the Duchy of Mazovia. Therefore, he proposed to fight a head-to-head battle on the plains outside Warsaw, and the battle would be decided by one defeat......

The Duchy of Mazovia is not far off, and the previous small victory has greatly boosted their self-confidence. Moreover, they also misjudged the situation, believing that Zygmunt I had just had a son and had no intention of fighting for a long time. So, the Duchy of Mazovia stupidly agreed to a head-to-head duel......

It was only after the war that the Duchy of Mazovia regretted it......

After the battle, Zygmunt I did not immediately show the hussars, but hid them behind the formation. At the front of the line is the most basic defensive spear formation. Then, there are the 1000 plate knights who decorate the façade.

"Ha, there aren't as many riders on the other side as we are!" Vazinsky, the general of the principality of Mazovia, said contemptuously. Because, the Duchy of Mazovia has a full 2,200 Plate Knights.

In traditional Polish warfare, the number of heavy cavalry often determined the outcome of the war. Therefore, the army of the Duchy of Mazovia could not help but be a little ......

As for the fear that Zygmunt I would hide the plate armor heavy rider behind? The generals of the Duchy of Mazovia were not worried. Why? Because the weight of the Plate Knight is too high, the time for the horse to charge once is limited. Therefore, it is not cost-effective to hide the Plate Knight behind the formation. Because, when the war horse carried the knight from the back of the formation to the front of the formation, he was out of breath, where would he have the strength to charge again?

Therefore, the general army will only put the plate knight at the front to save the physical strength of the horse and the knight. Therefore, the generals of the army of the Duchy of Mazovia also judged from this - the opponent had no more plate knights. Even if there were cavalry, it was light cavalry.

The light cavalry had little to do against the plate armor heavy cavalry, so they couldn't help but despise their opponents a little......

……

"Array, prepare to attack!" Zygmunt I ordered loudly. And the herald on the side, with a louder voice, loudly conveyed the orders of Zygmunt I. As the order was given, the banner of the Jagiellonian royal army began to wave, directing the army to line up......

On the side of the army of the Duchy of Mazovia, Vazinsky was not far behind and ordered:

"Tell our knight lads, get ready to charge! We must crush the opponent's cavalry once and take the lead! As long as we defeat their Plate Heavy, we've won! ”

But he didn't notice that after Zygmunt I on the opposite side gave the order to attack again, he waved his hand and sent a herald around the back of the line......
