The guns and cannons on the front suddenly became denser, and the Austro-Hungarian army launched a counterattack.

They wanted to drag me here, but this strengthened his determination to retreat, and it must be fast!

He hung up Sturm, "Hey, man, I need to retreat."

"I know." The sound on the other side of the phone seemed very calm.

"I need to stop the Austrian army from crossing the Sava River." Spanternovitch said, "God knows, I just hope to retreat safely, damn Frenchman!"

"It's hard to do. The news I got is that the enemy has crossed the Sava River from two places and is very strong!" said Sturm. "I will also start retreating before dawn. I hope you can leave a way out for me."

The two Serbian generals worked together for many years, but they were able to cooperate sincerely and cooperate closely. Although there were some minor conflicts in normal times, they would never act voluntarily on major military issues. This is the key to their ability to win the Battle of Varevo, which is different from the Russians.

At the same time, the 1st and 2nd Marine Divisions of the Austro-Hungarian Empire had already crossed the Sava River in the Osayek area, with the two attack troops being 10 kilometers apart, which made the defensive Serbian troops lose sight of each other.

Armed swimming is a necessary training subject for the Marine Corps. The width of the Sava River is naturally not a problem in the eyes of the Marines who can arm the swimming twenty kilometers in the sea. In addition to the artillery units, including commander Brigadier General Clemens Bezel, they swam through the autumn river water, with a total of four infantry regiments.

There was only about one regiment of the Serbian defensive forces on this line. Two land divisions immediately launched an attack after crossing the river. After about an hour of fighting, the Serbs finally dispersed. Clemens left a regiment to defend the ferry and led the other three regiments to continue attacking in depth.

Before dawn, the engineers of the 7th Army of the Austrian Army had already set up five pontoon bridges. The main force of the 7th Army was continuously passing through the Sava River from the bridge. The Dalmatia runner-up to the south, the Tyrol army to the north, and the heavy artillery troops belonging to the various divisions of the army were in the middle.

Lee Haydn set up his command center by the river. Of course, he would not cross the river rashly. The victory or defeat of a battle is not enough to make him take risks with his life. He just wanted to get closer to the front line so that he could understand the situation and changes ahead in a timely manner.

The Serbian army had retreated from the city of Sermia and was moving quickly enough. Brigadier General Clemens commanded three land regiments to block the Serbians' retreat.

"Order the troops to speed up crossing the river and immediately go to the front line, and don't care about the heavy artillery troops!" Li Haidn issued an order. The troops that had already crossed the river were sorting out on the other side, and he needed them to join the battle as soon as possible.

The increasingly fierce gunfire sounds in the northeast made him feel that this would be a tragic battle.

"Damn it, where did they come from so many machine guns?!"

Szepannovic put down the telescope in his hand and clenched his right fist hard.

Just now, he invested a whole division of troops to attack the weakest right wing of the enemy's right wing, but he still failed.

In front of the position of the 3rd Austro-Hungarian Marine Corps, the bodies of Serbian soldiers were lying. At this moment, this green land with lush trees and crops on the day before had become a mess. The morning sun shone on this land covered with craters, with smoke filled with smoke everywhere, and the broken tree stumps and weeds burning, emitting green smoke.

The combat effectiveness of this Austro-Hungarian army can be regarded as tenacious and very tenacious. There can be clearly seen many broken bodies that were blown away on their positions, and they can still hold on under the blast of 50 cannons. Szepannovic once firmly believed that he could open a retreat before the Austro-Hungarian army completely crossed the Sava River. After all, it took time for the enemy's army to cross the river. Now, his determination has been a little shaken.

"A path must be opened, do whatever you want!" Szepannovic gave the order. Now he no longer cared about Sturm, who had already begun to retreat.

"Hiss..." Accompanied by the sharp whistling, the Serbian attack began again.

"Boom! Boom..."

The shells continued to explode on the position less than 5 kilometers defended by the Third Austrian Marine Regiment. The entire earth was shaken. Large groups of soil were thrown into the air and then poured down like rain. The soldiers lowered their bodies in the trenches more than one person, enduring the violent vibration and fear brought by the violent explosion.

The shelling lasted for nearly twenty minutes. This time, Sidepanovich fought his life and ordered the artillery troops to drain all the remaining shells. Anyway, he could no longer take these things away.

"The enemy is coming, come back to the shooting position!" The sound of cannons gradually stopped and became sparse. The officers were whistling their whistles and running back and forth in the trenches.

The Serbs rushed up like a tide. Stypannovic had no choice but to order his troops to press the entire line and rush to the Austro-Hungarian positions. The Third Land Regiment and the 2nd Dalmatia Division who came to reinforce were submerged, leaving only some mountain positions in their hands.

The Serbian army was not in a hurry to clear out these Austrian troops who were still defending in the stronghold. They rushed out of the gap. By the time the Austro-Hungarian Empire's subsequent reinforcements sealed the gap, 50,000 Serbs had already rushed through the defense line. The 1st Mountain Infantry Division of Tyrol, with the best physical strength, took on the pursuit mission, and more than 15,000 people were chasing the 50,000 Serbian troops behind them.

Sturm's Serbian Third Army and Second Army were surrounded by the Austro-Hungarian army, and no matter how hard it was, it would be useless.

Five days later, on September 6, Sturm, who had run out of ammunition and food, chose to surrender. In the Battle of Sermia, less than 40,000 Serbian troops escaped the Danube.

A huge victory was enough to slightly boost the decline and morale of the defeat in the Battle of Limburg. Condra was excited and ordered the Serbian front-line to start a full-scale attack.

Lee Haydn didn't even have time to deal with him. After a big victory, he ordered the troops to retreat and rest for replenishment and training, but ordered the defensive positions set up by Belgrade and Serbs along the Danube River with cannons every day.

"Why don't we continue?" Mayer was a little surprised. After a big victory, Lee Haydn retreated his command to Vitica. "We can take Belgrade and even the entire Serbia in one go."

"So what? Sville," said Leheiden. "Then they will retreat to Greece and continue to resist. Are we going to continue to march into Greece? Then our precious forces will be trapped in the entire Balkans and will also need to deal with the Serbian resistance groups in the defense. The focus of this war is not on the Balkans, but in the northeast."

"So we may be transferred to the Eastern Front?" Mayer said.

"It's not possible, but certain." Lee Hayden said, "Croatian local troops will be formed into the 13th Army and join the reorganized and broken 3rd Army. You will be the commander of the 1st Marine Army formed by the Marine Corps, and Bolojevic will be the commander of the 3rd Army. This has been confirmed. I will also lead the 6th and 7th Army to reinforce the Eastern Front, and these are in consultation with General Condra. Fortress Prèmere has been surrounded by the Russians and we need to go to rescue."

Now, although General Condra, the Chief of Staff of the Army, was a little angry that the crown prince had roughly interfered in his combat plans and command on the front line, he was not going to go against Lee Haydn.
