On the position of the 312th Regiment on the position of the 2nd Battalion.

"Sir." Ma Yuan hurried here during the day. The Tocharians had not yet surrounded their positions, and it seems that the Tocharians were not very well armed, and their large forces did not rush up.

"How's it going?" Ma Yuan asked directly.

"Sir, yesterday, this morning, after several small, tentative attacks by the Tocharians, they stopped attacking. They began to follow our example, digging trenches and building fortifications. Li Lin replied.

"Hmm." Ma Yuan nodded.

"It seems that the Tocharian offensive has stopped." Ma Yuan nodded and said happily.

"Yes, sir, but sir, I'm still a little worried." Li Lin said at this time.

"What are you worried about?" Ma Yuan asked.

"Sir, it's like this, the mountainous terrain here is complicated, and I'm afraid that the Tocharians will adopt some roundabout tactics, for example, they will divert our attention and bypass us from a more flank position, and in some places there are still Yueshi people to control, but in some places there are no Yueshi people to control. It was easy for them to get around, the road here was not the only one, just cross the mountains to get into our rear. Li Lin said worriedly.

"If that's the case, there's no point in us defending here." Li Lin said.

"That's right, we need more reinforcements." Ma Yuan nodded and said.

"I think the domestic side may soon mobilize more troops to come here, rest assured, our rear will be safe." Ma Yuan patted his shoulder and said.

"Sir. Sir. "That's when it happened. The second company commander, Donner, ran over, he was followed by two soldiers, two Qin soldiers, Ma Yuan glanced at them, their armbands showed that they were communications troops, and a soldier dragged a long cable behind him. Both soldiers were carrying large iron boxes, and they were panting and looking very tired.

"They are?" Ma Yuan asked curiously.

"Sir, they're communications troops, they're coming from the rear, and they're saying, what's going on." Donner didn't know the explanation, just looked at Ma Yuan.

"Sir, we are a telephone unit, a field telephone unit. A new unit of communication. A corporal came up and explained.

"What's your name?" Ma Yuan asked.

"Ma Fei. Sir. The corporal said.

"Hmm. Corporal Ma Fei, can you tell us what you are here for? Ma Yuan asked.

"Sir, I'm in charge of communications here, and the phone lines are very well set up, so we just need to run all the way here." Ma Fei explained.

"Sir, wait a minute, maybe you'll understand what I mean." Saying that, Ma Fei waved his hand, and then asked another soldier to pick up the telephone line, their sending and receiving were very skillful, biting with their teeth, it was much better than a special line pliers, their fingers looked thick, but they were very flexible, and they quickly tied the copper wire. That kind of copper wire is finer than the copper wire of the cable. Ma Yuan knew that these cables must be expensive, because wire drawing is a very delicate job.

"Buzz." Corporal Ma Fei picked up the phone and shook the lever a few times. It's a magnet phone. The Ministry of Defense has received all kinds of reports on the new achievements of Qin's research on the battlefield, in which they are all very dissatisfied with the current communications, and there is an urgent need for a communication tool that can directly issue orders from the division or military headquarters to the regimental headquarters, and the telephone can meet such needs. As a result, the magnet phone was soon equipped with the first batch of combat troops, Wang Ben and Li Xin.

"Hey, hey. Here is the 312 regiment. Hey, hey. Ma Fei shouted loudly. Ma Yuan watched all this quietly, and he felt that this should be able to succeed.

"Hey, this is the field call center, please call back when you hear it. Please reply when you hear it.

"Good. I've received it here, done. Ma Fei replied.

"Any requests? Complete. Said on the other side of the phone.

"Give me, I'll tell you." Ma Yuan took the phone and said.

"Yes, sir." Ma Fei gave the phone to Ma Yuan.

"I am the commander of the 312th Regiment, Lieutenant Colonel Ma Yuan. Complete. Ma Yuan said.

"Hear, sir, I'm Major Song Qiao of the Field Telephone Center. Complete. Song Qiao replied.

"Can you receive a message directly from here and send it to the rear command?" Ma Yuan asked directly.

"Yes, sir. But I'm worried that the phone line has just been connected and there is some instability, sir. Song Qiao said.

"It's okay, I'll start making a report now, you record it, and then send it to the rear immediately." Ma Yuan said.

"Yes, sir." Song Qiao took the banknote and began to record.

"The 1st and 2nd Battalions of the 312th Regiment were attacked by the Tocharians. The Tocharians suffered heavy losses, and we got creative land and the battle went well, but it wasn't going well. We feel that the Tocharians will continue to enter the area, and we are only defending a strategic point, the Yueshi have an ambiguous attitude, the Tocharians can directly bypass our defense zone and enter our rear, our rear is very unstable, I need reinforcements. Ma Yuan said.

"Please continue, sir." Song Qiao recorded. His pencil was writing quickly.

"We need more troops to defend. We need more supplies, and I'm afraid the Tocharian attacks will continue, or besiege us. For the Tocharians, their offensive weapons were not very good, a small number of flintlock muskets, no artillery, in addition, their armament used a certain number of iron weapons. Limited ability to fight at night. Ma Yuan reported.

"In addition, after the operation of our regiment, there is a lot of room for improvement in combat effectiveness. We need a certain trimming and fighting. That's it. Ma Yuan thought for a moment and said.

"Alright, sir, I'll send this to the rear as soon as possible." Song Qiao said on the other side of the phone.

"Okay. As soon as possible, thank you, thank you very much. Ma Yuan said.

"You're welcome, sir." Song Qiao said.

In order to solve the communication problem on the battlefield, the Qin army decided to invest a lot of money in the connection of communication equipment, especially the use of telephones, which could allow the Qin army to shorten the urgent pressure on communication, so that the Qin army could get information in time and respond. The telegram was quickly sent to Wang Ben, and after Wang Ben read the telegram, he just nodded. Agreed. He didn't want to know too much about the details of the battle, he just wanted to know what the situation was on the battlefield. Only by understanding this can he react further and make decisions.
