Conyito, the ruler of Mecklenburg and the chieftain of the Slavic tribes, finally arrived under Stralsund five years later.

Standing on a high place, Otto can clearly see Kang Yituo's appearance with a telescope, golden hair and beard, young and majestic face, wearing leather armor, lined with chain mail, and wearing a gorgeous coat behind him, riding on a war horse is very heroic. ”

As more and more Slavic soldiers appeared in everyone's field of vision with battle axes and round shields, everyone's hearts suddenly rose, and even the Norman baron, who had been clamoring for a decisive battle out of the city, couldn't help but close his mouth and clenched the hilt of his sword tightly in his hand, obviously he was also a little nervous in the face of so many enemies.

"The next step is to build siege equipment and assemble the stone throwing machine?" Odo saw that the opposing army was in full swing assembling some equipment, and it seemed that he was about to launch a strong attack on the city of Stralsund.

"Launch a flare and order Robert to lead the cavalry to attack the flanks of the place, and destroy their siege engines." Odu commanded the herald beside him.

"Yes." After the soldiers received the order, a scream sounded, and a rocket that had been prepared for a long time exploded an orange firework in the air, and at the same time, two lucky flags, one red and one yellow, were waved on the city wall, signaling to Robert's headquarters outside the city.

Robert's unit was a mobile unit deployed by Odo outside the city, mostly valuable cavalry units in the army, with a total of about 1,000 men.

They had already followed Robert's instructions and set up an ambush in a jungle not far away, and when they heard the explosion of rockets, they immediately moved into action, and under Robert's leadership, they galloped out of the woods and unexpectedly appeared behind the enemy's flank.

Robert and his Norman cavalry suddenly appeared behind the Slavic army, which was really a bit unexpected for them, and they were not mentally prepared at all, and the chief Kangyituo Gengo, who was in front of the formation, had no time to send reinforcements to counterattack, so he could only watch Robert and his Norman cavalry wreak havoc in the rear of the army.

The most painful thing for him was that the precious craftsmen who had been recruited with great difficulty were slaughtered by the Norman cavalry who suddenly came to the rear, and most of the siege equipment that they had assembled was burned by the Norman cavalry.

After Kang Yituo finally organized the army to expel the Norman cavalry, looking at the messy rear camp, he only felt a feeling of tightness in his chest, and he almost vomited blood in public.

If it weren't for the long time of infantry in his army, and the cavalry were only wearing leather armor or light chain mail, the right amount was not enough, and it could not withstand the Norman cavalry, where would these despicable sneak attacks get away with it?

Chief Kangyito searched the entire rear camp and found only two stone throwers in good condition and thirty or so artisan slaves shivering behind the baggage wagons.

"Ming they will make siege equipment again, at least they will make a ladder that can climb the city, and all the soldiers will also help!" As a last resort, Chief Kangyituo gave an order to make a ladder.

After Kang Yituo learned a bloody lesson this time, he no longer arranged the craftsmen in the rear, but used a large number of troops to protect them at all times.

But the slave craftsmen, who had almost perished under the butcher's knives of the Norman Iron Horsemen, were unwilling to make engineering equipment for the Slavs, no matter how much they were beaten.

In desperation, Kang Yituo could only promise them that the slave craftsmen would get only and gain wealth after the war, which made these craftsmen overcome their fears and began to make ladders.

Outside the Slavs' formation, Robert roamed around with Norman cavalry, sometimes spotting gaps to make surprise attacks on weak points, or harassing the enemy with surrenders and bows and arrows.

Kang Yituo was so disturbed that he had to send the only cavalry in his hands to drive away the Norman knights, but he was unexpectedly eaten by the Norman cavalry who had been prepared, and most of these Slavic cavalry were annihilated, and only a few riders escaped back into the military formation.

These riders brought back not only news of defeat, but also fear of the Norman cavalry, which permeated the army like a nightmare.

Chief Kangyituo was clearly aware of this, and in order to prevent the morale of the army from collapsing, he beheaded the rout riders who disturbed the morale of the army, and then ordered the whole army to attack the city with all its might.

At this time, the situation was very clear, and the best way to deal with the Normans, who had the advantage of cavalry and water superiority, was to fight quickly, otherwise the situation would become more favorable to the Normans over time.

What's more, there are two hungry wolves behind Chief Kangyituo - the Danes and the Saxons, and these enemies also have to be defended, and they must be routed as soon as possible and return to defend against these two enemies.

With the sound of a low trumpet, the Slavs, carrying dozens of ladders, roared towards the city wall hundreds of meters away, under the orders of Chief Kangyito.

On the ramparts, Otto and Burchard were unhurried in the face of the swarming enemy, even though they had only 6,000 men at their disposal to defend Stralsund.

"Tell each one to roar and fire stone projectiles!" Otto commanded in a loud voice.

With Otto's order, a long filled counterweight stone thrower began to fire, the high raised counterweight suddenly hung down, under the effect of the lever principle, the grinding disc large stone projectile was driven by the tip of the cannon to shoot out.

In the corner outside the city, where the Slavs did not pay attention, there were markers that Otto had already arranged, which were used to calibrate the range of the stone throwing machine, and with the assistance of these markers, the stone projectiles thrown by the stone throwing machine smashed into the dense crowd with unmistakable accuracy, and suddenly rolled out more than a dozen alleys of flesh and blood.

Just talking about the salvo, the Norman trebuchets inflicted hundreds of casualties on the charging Slavic soldiers, and inflicted an even greater morale blow on them.

"Small catapults are ready, and the guns are loaded with shotguns." Seeing that most of the Slavic soldiers were still stubbornly approaching the walls, Odo had to use a second line of fire.

Different from other countries' catapults, their small catapults were specially improved by the Norman Royal Military Factory, not only the later five-shot guns, which could fire five basketball-sized stone projectiles at a time, but also the loading was very convenient, and the rate of fire was extremely fast, and it was affectionately called "five-shot guns" by the Normans.

The guns were small guns dismantled from naval gunboats, which were loaded with scattered bullets or iron chips and used to strike enemy troops close to the city walls, inflicting pieces of casualties on the enemy.

So why not install heavy naval guns, it is because the walls of Stralsund are mostly civil structures, which simply cannot withstand the recoil of heavy naval guns.

However, the network of five guns and small artillery alone was enough to make these Slavs trying to climb the city drink a pot.
