At the beginning of October, the autumn harvest was over, and after Dolgon sent cavalry to protect the grain, the autumn harvest was basically guaranteed, but just as he was preparing to go south to support Yangzhou, the Ming army, pretending to be a Japanese robber, changed the way of fighting, concentrated the Ming army that was originally scattered and harassed, and attacked the city along the coast.

The location chosen by the Ming army was mainly mountainous Shandong, Xie Qian guarded North Korea to prevent the Qing army from attacking Korea, Ruan Mei led more than 10,000 elite soldiers, and Zheng Chenggong's naval division, plundered in Laizhou Mansion and Dengzhou Mansion, and even broke Changyi, Weifang, Huangxian, Penglai and other places.

Thousands of miles of coastline, so that the Qing army can not be guarded, for this kind of enemy from the sea, completely unable to deal with, the Ming army looted a large number of supplies, transferred to North Korea, until the siege of Dengzhou capital Wendeng County, was blocked by the Qing general Wang Zhongqing

Dolgon cobbled together an army of 50,000 and went to Jinan, but had to leave 20,000 people to guard Shandong to prevent the Ming army from continuing to cholera in Shandong County, and finally could only let Gushan He Luo lead 30,000 people to the south first, and after converging the 20,000 green battalions in Xuzhou, and then go to rescue Yangzhou.

The Ming army of North Korea held back the Qing troops in Beizhi and Shandong for nearly a month, and during this time, Zhang Mingzhen had already perfected the defense on the front line of Huai'an and Sizhou, and naturally blocked He Luohui to the north of the Huai River.

Although the reinforcements from Hefei were defeated by Li Guo and fled back to Fei, and the reinforcements from Beijing were blocked in Huai'an, the Ming army under the city of Yangzhou still felt great pressure.

When the time arrives in October, it will enter winter in more than a month at most, and if this year is still as cold as last year, then the entire Yangzhou campaign will fail.

After more than a month of siege operations, a ditch more than ten miles long and five zhang wide has approached Yangzhou City under the day and night struggle of hundreds of thousands of people.

At this time, under the city of Yangzhou, there is a magnificent and magnificent war scene, the Ming army is under the city, piling up a platform of earth, erecting wooden planks on it, covered with wet cowhide, defending against the cannonballs and artillery of the Qing army.

The artillery mount of the Ming army was fired on it, and the cannon sound of "boom" sounded from time to time, and the head of the city rose up with white smoke, and the iron bullet flew out of the smoke with a whistling whistle, shooting straight to the city, and smashed the wooden plank erected, but because there was a layer of cowhide on the wooden board, it did not cause sawdust to splash.

In the artillery array of the Ming army under the city, the gunners will wrap the medicine bag with a cotton cloth and write a number in the smoke of gunpowder, take it out of the wooden box, push it into the cannon chamber with a wooden stick, and then load it with an iron bullet, and then use an awl to pierce the medicine bag from the fire door, pour the ignition powder, and the soldiers in front will put down a baffle that covers the muzzle of the gun, and the gunner will immediately put the torch close to the primer.

After a long illness into a good doctor, several years of war, so that the Ming army summed up a lot of experience, just like the ****** of the firecrackers, the use of small clay bottles in advance, so that the quantitative launch, to avoid the tension of the battlefield, more or less gunpowder, so that the probability of the Ming army's guns to explode greatly reduced, and the promotion of this experience, it became the Ming army's artillery medicine package.

The Ordnance Supervisor absorbs the experience of using the canister to quantify the gunpowder, conducts hundreds or thousands of test firings on each type of artillery, finds a reasonable range of medicine, and forms a standard, wraps the quantitative gunpowder with cotton cloth in advance, and numbers the different amounts of gunpowder.

These slight changes greatly increased the life of the Ming artillery, and the rate of fire was much faster than that of the Qing army.

With the flickering of sparks, a cloud of white smoke rose, and on the artillery position, a deafening cannon suddenly broke out, the cannon body retreated violently, and the soldiers resisted the wooden stakes of the cannon body, all of which were loosened, and the thick white smoke covered the fort, and the city was full of white clouds.

A cannonball weighing more than ten pounds hit the city wall, the dust on the west city was flying, the city wall was hit by iron bullets, the wall bricks were broken, deeply dented, countless gravel flew and splashed, and fell into the moat like raindrops, splashing dense white splashes.

At this time, above and below the city, artillery fire roared, and iron bullets were intertwined, as if playing a passionate music.

In the huge roar of the cannonballs, the cannonballs hit the city wall, the shock brought by the shock, and the terrifying atmosphere created, tens of thousands of people pushed wheelbarrows, from the deep ditch more than two feet deep, like a dense school of fish, to carry away the excavated soil.

The artillery bombardment of the Ming army was to cover the people digging ditches, and as they dug close to the moat, the artillery of the Qing army in the city could kill hundreds of people every day, which soon caused panic among the people, and Chen Bangyan had to mobilize heavy artillery to fight with the Qing army at the head of the city to cover the digging of the ditch.

At the same time, the Ming army absorbed the experience of Wang Yan's attack on Wanxian, and spread a layer of arm-thick logs on the ditch within the range of the Qing army's artillery, and covered it with wet cowhide, and the people dug underneath, which was much safer.

The Qing army was very clear about the intentions of the Ming army, and the artillery and artillery trucks in the city were all focused on here.

From time to time, there were burning fireballs in the sky, which were fired by the artillery carts of the Qing army hiding behind the city wall, made of bamboo into a circle, stuffed with cotton soaked in fire oil, wrapped in a layer of cotton cloth outside, poured with fire oil, and then ignited, thrown out of the city with a stone thrower, rolled on the logs laid by the Ming army, and ignited a raging fire.

However, the Ming army laid cowhide on the log, and the fire could not be burned through for a while, and the Ming soldiers who hid behind the baffles on both sides immediately rushed out in the gap between the Qing army's launches, picked up a long pole with a hook, and hooked the burning fireball away.

In addition to the fireball, the Qing army also fired artillery, and the 100-kilogram boulder was thrown out, smashed on the log, and broke immediately, but it was caught by the cowhide and did not hurt the people below.

In the offensive and defensive battle of Yangzhou, in addition to digging canals and fierce shooting, the most tragic was the battle for the high ground outside Xicheng.

Duoduo attacked Yangzhou that year, and was very impressed by the high slope outside the west city, it was precisely because he controlled the high slope at the beginning, so he easily bombarded the west city, and then attacked the city several times from here, until Wang Yan attacked the high slope, his strategy of attacking Yangzhou was changed from a hard attack to a long-term siege.

Therefore, Duoduo attached great importance to the high slope outside the west city, and sent the Qing Dynasty to lead 5,000 men and horses to garrison on the mountain, and built a stone village on it, which was very difficult to attack.

At this time, when tens of thousands of people were digging the canal, the cannonballs and arrows rained down the high slope of the west city were intertwined, forming a dense net.

The Ming soldiers were in this net, pushing the shield cart, holding the shield, and charging towards the high slope.

Behind the siege troops, hundreds of artillery pieces, hiding behind wooden planks, were raising their muzzles and pouring fire on the stone walled hillside.

Liu Shun, who was in charge of command, pressed the sword in one hand, walked back and forth in front of the formation, stopped from time to time, anxiously looked at the dense Ming army on the hillside and shouted to climb up, and people were constantly shot by the arrows of the Qing army and rolled down from above.
