On 14 June, Abahai sent an elite Eight Banners to deliver a message to Fort Victory, and arrived outside the Victory Pass.

The entrance of the victory pass is a stone-brick city gate across the Great Wall, which is wide enough to pass a large car. There is a wooden building built on the mouth. Outside the mouth is the victorious mouth urn city and the horse market.

The side of the horse market is 50 zhang long, the south gate communicates with the victorious mouth Weng City, the north gate outside the mountain and builds a big store, covers an area of more than 10 acres, more than 20 rooms, called the North Zhiyuan store, specializes in the carriage and horse business of the merchants outside the mouth.

The North Zhiyuan store is backed by a flat-topped mountain, called "Sweeping Horse Terrace". There was a fire road pier standing on the platform, and the pier soldiers had already discovered the Eight Banners. At this time, the people of the North Zhiyuan store went to the empty building.

The narrow space between the victorious horse market and the horse sweeping platform could not place as many mighty divisions as the Eight Banners. The official of the Wenguan led by Kurzen, who led the interpreter, rode his horse to the city to loudly express his intention to the Ming army.

There is a big pier platform along the spine of the Great Wall along the east side of the victory mouth, the length and width are eight zhang each, the height is four zhang, the stone brick package, the buttress is provided, the arrow hole is arranged, and there is a house in the center of the pier. This is the place where the guards are on duty, and it is called the side pier.

The defenders of the side pier put down the hanging baskets, and Kurchan put in the seven letters.

One of the defenders checked the letter several times and shouted to the lower team Kurzen: "You wait. ”

The defenders carried seven letters, "Wait and so on", and ran east along the Great Wall and entered the pass of the Mashi Building. The Mashi Building is a high and a low building, which is not only the symbol of the Mashi, but also the place where the two chiefs of the station, one Wen and one Wu, are located.

The military attache "on duty" was a thousand households. Qianhu took the letter and shook it suspiciously, listened to it, and didn't read it, anyway, he didn't know a word.

"You go back and wait."

Qianhu ordered the defenders to go to the civil official with seven letters.

The civil official looked at the letterhead text and grinned: "Good guy, the military gate, the governor, the lieutenant officer, the general soldier, the general of the East Road, and the general of the North East Road have one letter." Fortunately, there is still a letter from the garrison here, so I will send it to Zhenqiang Fort first! ”

Fifty steps south of Mashilou is Zhenqiang Fort. But these fifty steps are a straight-line distance, and one has to go around it if you want to get there.

Thousands of households ran down the Great Wall and returned to the wide main street inside the victory mouth with seven letters.

In the north-south direction of this street, there are Lao Ye Temple, Jietai, Hu Shen Temple just at the entrance, and then there are many shops on both sides of the street, Nanjing grosgrain shop, Hangzhou silk shop, Luzhou forging shop, Linqing silk shop, velvet shop, grocery store, and so on.

After running half a mile south, Qianhu came to the crossroads. At the entrance of the street is a building called "Zisai Pavilion", with four gates in the south, east and west.

The east gate of the purple pavilion is less than twenty zhang is the town of Qiang Fort.

The south gate of Zisai Pavilion is the continuation of the commercial street, passing through the Nanzhiyuan store covering an area of more than 40 acres and more than 200 houses, and then passing through Erlidi is the victory fort.

Less than 20 zhang of the west gate of the Purple Pavilion is the market fort.

The so-called victory "one bite and three forts" are victorious mouth, victory fort, Zhenqiang fort and market fort.

The market fort city is three zhang high, the circumference is one hundred and eighty zhang, square, the stone brick package, open the east gate, and the top of the door is set up with the horse market building. The fort is empty and empty, and it is a large open-air market where trading is held. Every time the market opens, the city gate is opened as soon as the bell rings, and the merchants who live in the south and north Zhiyuan stores gather in the market fort to trade.

Zhenqiang Fort can be described as two sides on both sides. Because the Great Wall has turned a bend here, Zhenqiang Fort is the Great Wall 50 steps to the north and 50 steps to the east. The Great Wall defended by Zhenqiang Fort is a total of 22 miles, including 28 side piers and 7 fire road piers. The fort wall is three feet eight feet high, the circumference is one mile and seven minutes, and there is a garrison stationed in it, one thousand and fifty-three officers and soldiers, and two hundred and sixty-eight horses and mules.

Qianhu trotted into the garrison mansion.

The garrison was nervous, unsure whether to ask for reinforcements from Fort Victory.

The garrison opened the letter, read it several times, and instructed Qianhu: "You hurry back and guard the side wall and wait, I'll go to find the general." ”

The garrison took seven letters and mounted their horses, and galloped south out of the town of Qiangbao. Only two miles away, the garrison dismounted and entered the Victory Fort.

Desheng Fort is the general station of Datong Town's sub-patrol of North Hebei Road North East Road. The wall is three feet high and eight feet high, with a circumference of three miles and four minutes, and a stone brick package. There are eighteen enemy platforms on the city wall, and each one is equipped with a thousand-pound general cannon. There were 2,960 officers and 1,191 horses in the fort.

The crossroads of the victory fort are "Jade Emperor Pavilion", and the east of the Jade Emperor Pavilion is the General's Mansion. There are 300 gunpowder magazines, bomb rooms, arrow islands, and barracks around the General's Palace. To the west of the Jade Emperor Pavilion is the civil office, and there is a civil official stationed in the seventh grade.

The Zhenqiang Fort garrison went directly to the General's Mansion. In addition to controlling the Victory Fort, the Victory Fort Counselor can also dispatch the other seven forts, counting six garrisons and one integrity, which is the top boss of the garrison.

The general was informed of the warning and was waiting in the palace. After reading the letter, the general smacked his lips and said, "How dare you and my brother call the shots in this matter." The old man is in Hongci Fort, so I'll go over. You hurry back and keep your mouth and wait. ”

The general called the housekeeper, took seven letters, and rode out of Fort Victory all the way to the south.

Not long away, the staff will encounter another "Great Wall".

Datong Town can be described as a dense Great Wall.

From a macro point of view, Datong Town and Xuanzhen are located between the two Great Walls, which are called the first road side and the second road side respectively. Within the second border, the Ming Dynasty also had a second line of defense at the strategic level.

From a microscopic point of view, after the first road, you have to pass through two "rejection walls" to get to Datong City. The victorious mouth between the first wall and the first side wall is only the first tactical line of defense of Datong.

Passing through the secret gate of the wall, beating the horse for twenty miles, the general arrived at Hongci Fort. Hongci Fort is also the jurisdiction of the generals, but whenever there is military tension, such as the opening time of the horse market, the sub-patrol road or Datong Dao will be located in the town to assist in the defense.

Now that there has been chaos outside the border for so long, it is the general army of Datong who is the town of Hongci Fort.

The garrison of Hongci Fort hurriedly led the way, and the general saw the chief soldier and handed over the letter.

After reading the letters in the letter, the general soldiers of Datong read the letters, one was Dong Dazi asking for Chahar's reward, and the other was actually Dong Dazi asking for peace.

The chief soldier pondered for a moment and stood up.

Da Bingjia Ding lifted the net pot, and the chief soldier cleaned his hands with running water, put on a white hat, and groped for it. Call: "Pillars!" ”

The general hurriedly agreed: "Old man, I'll listen." ”

"Housheng, this matter is not something that we martial artists can get involved in. You go back to defend the Victory Fort first, and I'll go to Datong." ”

"Old man, what should I do if Dong Dazi urges?"

The general soldier of Datong frowned slightly: "Tell them to wait!" ”

The general army led a team of family members out of the city to the south through the second rejecting wall, and rode sixty miles to Datong City.

Datong City, with a circumference of thirteen miles, a wall four feet high and two feet high, 22,709 officers and soldiers, 16,992 horses, mules and donkeys, responsible for 42 fire road piers, stationed in the palace of the acting king, the governor of Datong, the general army of Datong and the emperor's monitoring eunuchs.
