Osaka is located on the northern side of the Seto Inland Sea, and the naval fleet of the Tence Army floated into the sea, landed on the south coast of Osaka, and went straight to Osaka Castle.

The army that landed in Osaka was the 2nd Brigade of the Tence Army and two Security Brigade with 9,000 troops, and the other two Tence Army Brigade and four Security Army brigades were transported by the main fleet to the vicinity of Nagoya in Ise Bay to await reinforcements from the shogunate.

The tactic formulated by the General Staff was to encircle the point and send reinforcements, and the General Staff thought that instead of crossing hundreds of kilometers all the way to attack Edo, it was better to surround it and wait for the main force of the shogunate army to send it to the door.

Osaka, the largest city in western Japan, was once the old capital of Japan, and the shogunate had to come to the rescue.

Nagoya is also located in the heart of Japan, serving as a transportation hub for both eastern and western Japan. If you enter western Japan from the Kanto Plain, where Edo is located, you will definitely pass through Nagoya, which is the gateway for reinforcements.

Nagoya is also one of the six major cities in Japan in this time and space, and the residence of the lord of the Owari Domain, if you attack Nagoya, it will also become a pain point for the shogunate.

Encirclement and reinforcement requires accurate intelligence to understand the movement of the enemy army, which is not difficult for the Tiance army, because it is supported by aerial reconnaissance.

After defeating the enemy's reinforcements, the will of the besieged defenders will be shaken and forced to surrender.

However, the Tence army did not need to follow this path, and after confirming that Osaka Castle had sent messengers to Edo, the Tence army immediately surrounded Osaka Castle.

The defenders of the city were nervous, and the hundreds of thousands of residents of the city were panicking. There used to be a very lively market outside Osaka called Joshita Town, and people from outside the castle also ran into the castle.

From the castle tower in Osaka Castle, you can see the Tence Navy's warships, and the huge hull of the ship is the source of panic in the castle.

The Japanese seem to have learned the technique of the artillery carriage from the Dutch, and the Hongyi cannons on the city wall were able to move in the direction of the enemy's main attack, and the twelve heavy cannons at this time had already moved to the direction facing the Tiance army.

"Tong, Tong, Tong!" A few puffs of white smoke came out of the head of Osaka City, and the defenders actually took the lead in firing artillery, and the distance was three kilometers, which startled the Tiance army and made hidden actions one after another.

"Knock, knock, knock!" The cannonballs fired at the head of the city fell a kilometer in front of the Tiance army, and it turned out that the defenders of the city opened fire because of nervousness.

The counterattack of the Tiance Army immediately began, "All of them, all of them!" "Thirty-six self-propelled howitzers served as the main force in the siege, and the first to be hit was the battery on the walls of Osaka Castle.

Amid the deafening sound of artillery fire, the heavy grenade crossed a distance of three kilometers at high speed and slammed into the head of Osaka Castle, sending out a huge explosion.

The defenses made of boulders and lime were completely unable to withstand the bombardment of modern heavy artillery, and the masonry flew everywhere with the explosion of the shells, and a large amount of masonry fell into the water garden.

The first round of shelling caused serious damage to the battery, which temporarily protected the artillery inside, but could not protect the artillery inside.

This kind of fort that defends the bronze cannon of this time and space cannot stop the shock wave of modern heavy artillery. In the first round of shelling, hundreds of Japanese artillerymen were shocked to death and wounded, whether they were dead or wounded, their behavior was the same, blood oozed from their mouths, noses and ears, and most of them had their eyes protruding outward.

The wounded who did not die were actually worse than dead, and their internal organs had already been shaken.

The second and third rounds of shelling followed, and the forts made of huge stones in the Osaka Castle Wall finally collapsed because they could not withstand the heavy artillery bombardment.

Shells were fired into the fort one after another, and in the huge explosion, the heavy guns weighing more than a ton were blown over and blown away, and some were even collapsed into the moat from the city walls.

In just half a minute, Osaka Castle was bombarded by more than 200 heavy grenades, 12 heavy artillery pieces were completely destroyed, and the batteries located in the direction of the main attack of the Tiance Army had basically collapsed.

Subsequently, 48 Type 38 guns of 105 caliber from two brigades of the security army also joined the shelling. More than 60 85-millimeter antiaircraft guns on surface ships also dropped shells on Osaka Castle, five kilometers away.

The 60 mortars of the 2nd Brigade of the Tiance Army began to drop shells into the city, and the mortars were curved guns, which were sharp weapons against the enemy above and behind the city walls.

The entire city of Osaka boiled like porridge in a boiling pot, and the sound of explosions became the main theme of the city, and the smoke, rubble, and fire were like a raging storm.

Osaka Castle was already in a hellish situation on earth, and the broken city walls were full of dead and wounded soldiers, who were originally hiding behind the city walls to prevent the Tiance army from attacking the city, but instead of welcoming the Tiance army, they were greeted by a rain of shells.

Some of the dead and wounded soldiers had been hit by flying fragments of the city walls, or smashed by masonry, with severed limbs and shredded flesh strewn all over the floor, and the smell of blood was like a slaughterhouse.

Blood flowed like a spring from the wounds of the wounded and wounded soldiers, and was everywhere on the nearly one-kilometer-long southern wall of Osaka Castle.

Sticky blood flowed down the walls and into the moat beneath the walls, staining all the nearly kilometer-long moats south of the walls red. The moat, which was more than three miles long, looked like it was full of blood at this time.

The wounded lay on the ground groaning and convulsing, but the soldiers next to him had nothing to do, the shelling was like a raging storm, and the only thing the surviving soldiers could do was hold their heads and tremble.

Toyotomi Kunimatsu, the lord of Osaka Castle, was so shocked by the bombardment of the Tence Army that he couldn't imagine it.

As the grandson of Toyotomi Hideyoshi, what he left in his bones was an indelible pride, and the shelling was so fierce that it aroused his ruthlessness.

Rather than sit and wait for death, he decided to lead the soldiers of Osaka Castle out of the city.

Zhou Yan, the commander of the Second Brigade, was watching the shelling with a telescope, and this time he used so much artillery against Osaka City, and the bombardment was so fierce, it was completely arranged by Wang Yue, and he wanted to use ferocious firepower to break the backbone of the Japanese.

Just as I was watching the excitement, the south gate of Osaka Castle suddenly opened, and nearly 10,000 horses rushed out from inside, shouting and rushing towards the position of the Tiance Army.

This is the remnants of nearly 8,000 Osaka Castle led by Toyotomi Kunimatsu, the lord of Osaka Castle, who almost poured out.

The artillery bombardment was so fierce that the defenders of Osaka Castle had already killed and wounded nearly a third of their troops, and under such artillery fire, staying in the city was waiting for death, so Toyotomi Kunimatsu ordered the whole army to fight outside the city and fight with the enemy.

In comparison, the shogunate army was more of a regular army than the rebel army, and most of the soldiers had simple armor, while almost everyone in Toyotomi Kunimatsu's family army had armor.

This can also be seen that the Japanese daimyo had a certain amount of financial resources to arm the army, which is one of the reasons why the shogunate was able to hold off the two rebel forces.
