In the middle of the night, Marin sent his men to cross the mountains and mountains overnight, bypassing the camp of Sienese reinforcements, and came to the mountain road leading to Grosseto in the southwest, and hurried southwest to contact Saqara in advance to form a cooperation.

The next morning, after a journey in the middle of the night, Marin's messenger finally met the Fourth Legion, which was on the march......

"What? There's an enemy reinforcement confronting the Grand Duke? Need me to lead the encirclement? Okay, all the attention of the whole army, speed up! ”

At noon, the Fourth Army finally arrived a few kilometers away from the south gate of Siena and blocked the retreat of Sienese reinforcements......

After stubbornly resisting for half a day, at night, seeing that the retreat was blocked and the enemy was strong, the commander of the Sienese reinforcements, Caramosi, who felt hopeless, had no choice but to surrender.

……

Marin attached great importance to the surrendered Caramossi, because he wanted to use Caramossi to deceive the gates of Siena......

But the Sienese defenders were too shrewd, and when Caramossi led a "remnant of the army" to the south gate in the middle of the night and asked to enter the city, the defenders refused to open the door. The reason for the refusal was simple - the city gates were blocked......

Then, the defenders offered to take them into the city with hanging baskets......

However, this "remnant army", except for a few leaders such as Karamosi, is all the army of the Beihai Kingdom. If you are pulled up by the hanging basket, you don't know it at first glance, and you won't be hacked to death with a knife? Therefore, Karamossi had no choice but to lead the people back in a foolish manner......

……

Marin was very disappointed and did not warm up to Caramossi. And Caramossi, knowing at this time that he had already boarded Marin's thief ship, and it was difficult to get off the ship, he simply tried his best to help Marin think about it. Because, he thought - this time the Holy See dispatched such a large army, the Republic of Siena will definitely be finished, it is only a matter of time. If he had made great contributions before the fall of Siena, when Siena was finished, he would be able to continue to help the Holy See and keep his wealth...... So, he offered his plan to Marin......

"What, you said you were going to open the gates of Radikofani?" Marin was a little surprised.

"Yes, Grand Duke, the defenders of the city of Siena were led by Governor Pandorf. Petruch personally commanded. Mr. Governor has always been cautious and suspicious, so it is not surprising that we have failed in our deception. But Radikofani's defender, General Sarimoe, was different, this general was of average intelligence and not so suspicious. If you use the trick of the Grand Duke and you pretending to be a rout in the middle of the night to deceive the city gate, the other party will be fooled nine times out of ten. Moreover, I was originally one of his most important generals, and I personally led people to deceive the city, and the possibility of the other party being deceived is extremely great! Karamothy said confidently.

"Radicofani......" Marin touched his chin, but fell into deep thought......

If others don't know, Marin must know it in his heart. Don't look at the 20,000-strong army of Maximilian I outside the Radicofani Pass, but they are actually only acting, not fighting. Even if you put them in the gate, it won't be of much use. Because, His Majesty the Emperor is not stupid and will not really make every effort to help.

Moreover, with the steep terrain of Siena City, even if another 20,000 troops come, it is actually useless. In other words, even if the Sienese army guarding the pass was defeated and the emperor's army was put in, it didn't seem to be of much help......

"No......" Marin suddenly thought of a question - although the emperor's army would not really help in the battle, if the Sienese army guarding the pass was eliminated, it would definitely be a major blow to the defenders of Siena City!

You must know that the defenders in Siena are probably also expecting more than 10,000 defenders at the Radikofani Pass. If they had learned that Radikofani's defenders had been wiped out, they would have felt despair, and their morale had plummeted......

In the end, Marin still made up his mind - to lead his troops to deceive the Sienese border pass of Radikofani and cut off the hope of the Sienese......

Therefore, Marin handed over the task of continuing the siege of Siena to the Fourth Army, and he himself rushed to the Radicofani Pass with the army, as well as Karamossi and other generals.

……

And after Marin left, Saqara took over the responsibility of the Mountain Infantry Corps and began to continue the siege of the city of Siena. Because the Fourth Army came by the main road, it brought all the baggage and deterioration artillery. Saqara simply ordered the artillery to be erected and began shelling each other with the enemy troops on the three gates.

Moreover, the purpose of the Saqqara shelling was not to break the city gates. After all, he brought a 6-pounder cannon, and it was impossible to break the cast-iron gates of Siena. He ordered artillery to bombard the Sienese defenders on the tower of the city gates, especially the artillery emplacements. The purpose of this was to consume the gunpowder of the defenders in the city. Because, Saqqara received a message from the captured Sienese reinforcements - the defenders of the city did not have much gunpowder. This was mainly due to the fact that the Sienese were poorly prepared for war and did not have time to stock up on sufficient gunpowder. So, Saqqara simply bombarded each other with each other in order to consume each other's gunpowder.

Moreover, in order to protect the artillery, Saqqara ordered the artillerymen to carry 6-pounder guns, and change places with one shot, so that the defenders on the head of the city did not have time to aim. Of course, in order to consume the gunpowder of the artillery at the head of the city, the artillery of the Fourth Army specially waited for the opponent to fire before withdrawing from the original position. The so-called calibration means that the first shot of the artillery is generally inaccurate and needs to be adjusted again. In the era of smoothbore guns, it was often necessary to adjust several times to hit (except for flat fire). Although the artillery at the head of the city has the advantage of being condescending and having a long range, the only problem is that it cannot fire directly at the front. Because, if the muzzle is lowered, the iron ball shell inside the barrel of the smoothbore gun is easy to roll out. Therefore, the artillery on the head of the city needed to be projectile. And the artillery under the city, firing from the top is not so much trouble. Of course, it is also necessary to take into account the situation of the ballistic bending of the shell, but it is much better than the city-head artillery. And the characteristics of the city's artillery are that the closer it gets, the more difficult it is to aim, unless it hits a crowd, as long as the muzzle is in the right direction, it can always kill a group of unlucky people......

If you shoot at the artillery under the city at close range, the artillery at the head of the city is a little blind. Smoothbore guns should not always be able to shoot at a large angle, and if they are fired at a distance and from a small angle, it is not easy for the shells to roll out. The artillery of the Fourth Army Corps was supported by the First Army Corps, and they were all old fritter artillery, and they were very familiar with the characteristics of the city defense artillery. So, they came directly to a distance of 100 meters below the city, which could not only avoid the opponent's bows and arrows (they also wore breastplate armor), but also easily hit the artillery at the head of the city, and also made the artillery at the head of the city very uncomfortable, and could not shoot directly down. The artillery of this era was fixed and could not be moved casually. Only the artillery of the Beihai Kingdom was pushed around because of Marin's invention of a movable gun mount, so that the artillery at the head of the city could not be aimed, and it was impossible for them to shoot slowly......

……

After three days of marching, Marin finally arrived at the foot of the city of Radicofani with Karamosi and other Sienese soldiers who had surrendered. According to Karamosi's introduction, because it is a pass, the defense force of the northwest gate of Radikofani is very small. Moreover, it did not block the hole in the city gate, so it was easier to open it.

In the middle of the night, Karamosi took a few surrendered Sienese officers and more than a hundred real Sienese soldiers to take the lead, and arrived at the gates of the city of Radicofani with more than 2,000 Beihai soldiers disguised as a rout.

"Open the door, I'm Caramossi!" Coming to the city gate, Karamossi took the lead, raised his head and shouted.

The officer guarding the city gate looked at it - ouch, it was General Caramossi. However, as a city gate official, he is not qualified to let people into the city in the middle of the night. After all, although the military discipline of the Italian army is not good, there are still basic rules. So, he hastened to report it to General Sarimoe.

Sarimoe was woken up in the middle of the night and was furious. But Caramossi led his troops back to Siena, and actually fled back, which frightened him very much. So he came to the gate tower and asked:

"Piero (Caramossi's full name is handed over to Piero. Morality. Karamosi), didn't you go back to the city of Siena, how did you come back? The enemy is strong? ”

"Yes, my lord, we have encountered the enemy army that attacked the city of Siena, they are German mercenaries, not ordinary Italian mercenaries, it is estimated that the 7,000 mercenaries of the North Sea Kingdom who are guarding Rome! We were defeated and had to flee back! Fortunately, the mountain road is narrow, and the other party can't spread it, otherwise we wouldn't be able to come back alive! Karamossi said aloud according to the "script" she had worked out with Marin.

General Sarimoe thought about it, and it seemed that the city of Rome did have Marin of the North Sea State. The 7,000 mercenaries that Hoffman provided to the Pope at the beginning were indeed more effective than the Italian mercenaries. However, he still had some doubts about Caramossi returning with his army in the middle of the night. So, he asked:

"Why did you come back in the middle of the night? Can't you wait until daytime? Of course, Sarimoe wasn't suspicious. Because, in the history of Europe, there is no precedent for this kind of midnight fraud, so he naturally will not be vigilant.

Karamothy had already taken a countermeasure, and he replied:

"My lord, the enemy will chase after you! If I hadn't come back with someone at night, I guess they would have been chasing after me. Tomorrow morning, they will find out that we have abandoned the camp and run away, and they will definitely catch up! ”

Karamothy answered without any questions, and the more than 100 people standing in the front row were all familiar faces. Sarimoe thought about it, and felt that there was nothing wrong with it, so he ordered the city gate to be opened and let him in...... As a result, Marin's army finally succeeded in deceiving the gates of the Radikofani Pass......
