In this battle, the Ming army defeated 300 Spanish soldiers by night attack.

Killed 91 Spaniards on the spot and captured 61.

Gil'an's troops lost more than half of their strength in one night, not counting the baggage weapons that had fled from the camp in a hurry.

After the First World War, the Ming army captured more than 40 smoothbore flintlock guns, more than 200 metal grenades, more than a dozen pairs of plate armor, and a large amount of gunpowder.

With the captured weapons of the Spaniards,

Liu Yu directly expanded the Third Association, and at the same time formed a grenadier association specializing in the use of hand grenades.

In just one day, the firepower of the Shenji Battalion has more than doubled.

The six nine-pounder Saiko guns and more than 40 Spanish artillerymen captured on the hill surprised Liu Yu even more.

A few hundred meters away from the lateral direction of the battalion is the mound where the Spanish artillery is located.

Due to the sudden rainstorm, the Spanish artillery responsible for supporting the artillery bombardment of Ming City was muted for a while, giving the Ming army time to breathe.

When Gilan ordered the withdrawal of the troops, it was too much trouble to drag them back to the camp because the artillery was too heavy, and Gilan threw them directly on the hill.

Along with the artillery, more than forty artillery men remained.

This allowed the Spanish artillery to be captured by the Ming army intact.

Officer Brewster was the commander of this Spanish artillery unit.

At this moment, he and more than forty subordinates were tied up by the Ming army and knelt on the ground.

The Spaniard looked at the Ming soldiers on the side with a horrified expression.

And Captain Brewster's face was not very good,

The reason is also very simple, there are twenty bloody heads at his feet.

Captain Brewster swore to God that he had never seen such a barbarian.

Just when he led the artillery to camp on the hill and prepare to rest,

These shameful Orientals went so far as to directly attack the camp of their own people.

Guarding this artillery was a grenadier.

But when hundreds or thousands of Orientals rushed over, a dozen or so grenadiers were overwhelmed by the sea of people in an instant.

The scene that followed was something that Lieutenant Brewster and the dozens of Spanish artillerymen present will never forget.

The black-pressed group of Orientals were red-eyed, screaming and desperately slaughtering, and went straight to engulf the grenadiers.

After the poor grenadiers were cut to the ground by these Orientals, they were directly dismembered by these crazy Orientals.

The Eastern demons went crazy and tore at the corpses of the grenadiers, cutting off their heads one by one, and then a group of people scuffled over them.

Thankfully, one of these Orientals looked like a general who stopped the massacre.

Otherwise, I still have dozens of subordinates now, and I am afraid that they are no different from these poor grenadiers.

"Why hasn't Colonel Gil'an come yet, there were bursts of gunfire in the camp last night, could it be possible?"

"Impossible," Captain Brewster shook his head,

That's the elite Spanish field troops,

Unlike other mercenaries hired by the colonies, he and Gir'an and many of the soldiers in this army were sent from within Spain.

How could it be possible to lose to these Oriental natives?

Just as Lieutenant Brewster was worried about the outcome of the battle, a young man approached.

"Which of you is the commander of this force?"

Suddenly, an unfamiliar voice came,

The Spanish artillery raised their heads,

Lieutenant Brewster also looked at him in surprise.

Standing in front of him was a delicate young man,

He is short in stature, and his face is much whiter and more tender than those raw.

Although he couldn't understand the young man's words, the gentle tone still made Captain Brewster secretly breathe a sigh of relief,

It seems that the other party is not a demon.

"Which of you is the commander of this force?" Suddenly, an inaccurate phrase came from Spanish.

Lieutenant Brewster was agitated and stood up straight from the ground.

"Oh, it's you." Liu Yu looked at the middle-aged officer in front of him who suddenly stood up.

The beard on his face was a head taller, and his blue eyes were staring at him restlessly.

"Captain Brewster, Artillery Captain of the 1st Field Battalion in Manila." Brewster had no choice, when the blunt Spanish words came just now, he subconsciously stood up, and now it was too late to squat, so he had to bite the bullet.

Liu Yu nodded, picked up the long knife and slashed it down.

The rope tied to the lieutenant's body was cut by Liu Yu.

"Thank you." Captain Brewster, for some reason, spat out a Spanish phrase softly.

Liu Yu naturally didn't understand, and he motioned to Captain Brewster to walk to the high ground together.

Surrounded by several Ming soldiers, Captain Brewster had no choice but to climb the high ground.

It is said to be a high ground, but in fact it is a hill, which is only more than ten meters from the ground.

Six nine-pounder Saiko cannons were placed on the mound at the moment.

Captain Brewster looked at the young man in front of him uneasily,

He didn't know what the identity of this young man in front of him was, so he couldn't be the commander of this Ming army.

"Captain, can I ask you a few questions?" Liu Yu turned to look at the Spanish artillery chief.

The interpreter translated Liu Yu's words to Lieutenant Brewster.

"How far is this from Mingcheng?" Liu Yu asked.

"After calculation, it is roughly about 900 yards, that is, about two miles." Captain Brewster said.

In the Ming and Qing dynasties, the basic unit of distance was li.

In the Zhou Dynasty system, six feet is one step, and the li is one hundred and eighty zhang, and after the Tang Dynasty, five feet is one step, until the Song, Ming and Qing dynasties, it is three hundred and sixty steps, and it is also one hundred and eighty zhang.

In the Ming Dynasty, one mile was probably less than 500 meters, and it should be about 400 meters.

In other words, the mound is less than two miles away from Mingcheng.

"How did you accurately shell Mingcheng?" Liu Yu stepped forward and looked at the Spaniard, who was a head taller than him, and asked.

Looking at the nine-pounder cannon in front of him, Liu Yu was a little puzzled, because the caliber of the cannon in front of him was still inferior to the red-coated cannon, why could it hit two miles away and destroy the red-coated cannon of the Ming army so accurately.

"When our artillerymen saw your long cannon bombarding the natives, they measured it with the gauge and fired at your wall." Looking at the young man's inquiry in front of him, Captain Brewster was a little surprised, but he still said it one by one.

"What is a cannon gauge?" After listening to the translator's words, Liu Yu asked.

"There are two kinds of gun gauges: rectangular and gun, which is used to measure the straight-line distance from the target to the gun, and gunnery is a tool for measuring the elevation angle required by the gun."

"Our gunner calculates the distance by moment of moment, calculates the desired pitch angle of the cannon according to the formula, and then uses the gun gauge to reach the desired elevation angle, and then fires."

After listening to Lieutenant Brewster's detailed introduction, Liu Yu couldn't come back to his senses for a long time.

In the seventeenth century, the European armies had already begun to calculate artillery shooting scientifically and systematically, and the soldiers of the Ming army, whether it was a Franc cannon or a redcoat gun, were still relying on the experience of veterans.

No wonder the Ming army will be defeated in the artillery battle of Mingcheng.

In fact, what Captain Brewster didn't say was,

The nine-pounder Cycko had an effective range of only 500 yards, or about a mile, but its maximum range was 4,000 yards.

Since the Spanish army used more than 10-pound cannons were too heavy to march and drag them under the Ming city, this time only the nine-pounder cannons were carried.

Thinking that the Ming army did not have advanced artillery, the Spanish army originally planned to place two artillery pieces on the hill to bombard the Ming army in the field.

Four artillery pieces were placed in the field one mile away from the city to shell the walls of Mingcheng,

Who would have thought that the Ming army would have so many artillery, especially after seeing the Ming army using large-caliber red-coated cannons, the Spanish artillerymen were also shocked,

The idea of piling the remaining four cannons on the position to bombard the Ming army city wall was rejected by Captain Brewster, and the artillery was dragged to the mound two miles away from the Ming city, originally just to listen to it and wish the natives under the city a blessing.

With his own experience and belief in God, he tried to shoot at Mingcheng, who would have wanted to hit one by one.

Then the Spanish artillerymen you look at me, I look at you,

Then put it on.

As a result, after the first shot, the uncontrollable Spanish artillerymen fired their guns vigorously.

If it weren't for the sudden heavy rain, it is estimated that Mingcheng would have been taken long ago.
