Fight against the forces of the Japanese Pioneer Group.

At this time, the First Route Army had just been under the auspices of Deputy Commander-in-Chief Wei Zhengmin, and the Fourth and Fifth Divisions of the Second Army of the original First Route Army were formally reorganized into the Third Front Army of the First Route Army in Hanyanggou, Dunhua.

Wei Zhengmin was discussing with Chen Hanzhang the future direction of the three fronts in the wooden house, when there was a noise outside.

"Chief, chief, a message from the Second Route Army." Wei Zhengmin's guards shouted as they ran with a message sent by the General Headquarters of the Northeast Anti-Japanese Allied Army.

"Slow down, show it to me." Wei Zhengmin said with a smile as he took the message and looked at it carefully.

"Is there anything going on with the Second Route Army, Deputy Commander-in-Chief?" Chen Hanzhang asked curiously.

After reading it, Wei Zhengmin patted his thigh and said with a smile: "Of course there is something, it is a great joy, after the discussion and discussion of the party committee, the Second Route Army, the Third Route Army and our First Route Army have united to form the Northeast Anti-Japanese Allied Army Headquarters, and the Second Route Army has joined the Third Route Army." ”

"It's turn, so what do we do now? Are there any new directives from headquarters? ”

Let's report the members over. ”

"Ahh Isn't the Third Front Army, which we just formed, made up in vain? Chen Hanzhang said.

"It's okay, we have to obey the organizational arrangement, I think we will organize your three front armies into the 13th Regiment!"

"Oh my God! In less than two days, the establishment of the army was organized into a regimental level. ”

"Don't complain, I'll leave in a moment and tell the commander-in-chief the news, the headquarters now orders us to quickly reorganize the troops, and the Sanjiang area will advance to the second detachment."

"Then we don't want this place, but the base we have built after many years has been wasted like this?"

The guard who had just gone out ran over with a telegram and said, "Chief, chief, the headquarters is in an emergency." ”

Wei Zhengmin looked at it for a while, then quickly got up and said, "Lao Chen, you are now hurrying up and reorganizing the troops and waiting for my news here, and I will immediately go to the commander-in-chief." ”
