Not to mention that the three monarchs and ministers of the Austrian Empire were still dreaming, just say that the Prussian Fifth Army led by Prince William, the crown prince of the Kingdom of Prussia, marched to the Danish Jutland Peninsula north of Schleswig.

The Prussian Fifth Army, composed of 50,000 troops, marched at great speed, crushing thousands of scattered Danish defenders along the way, traveling dozens of miles a day, and running long distances to break through the border between Schleswig and Denmark in one fell swoop, and enter Denmark.

At the same time, nearly 30,000 troops were hastily assembled from the island and Jutland Peninsula, gathered in Aarhusburg, an important town in the east of Jutland, in order to delay the attack of the Prussian army by garrisoning the fortress, but unexpectedly, under the high-quality military ability and strong firepower of the Prussian army, 30,000 Danish troops did not hold out in Aarhusburg for 4 days, and they were quickly broken, killing more than 4,000 people, and nearly 20,000 fled to Aalborg, the northernmost important town of Jutland. The rest of the thousands surrendered and were taken prisoner.

And Prince William did not hesitate at all, and directly ordered the Fifth Army to quickly pursue. The Danish army in Jutland's last military stronghold, Aalborg, was even worse, failed to hold out for 3 days before abandoning the fort and fled, but when they arrived at the port, they found that the Danish fleet and the Prussian navy were fighting fiercely, although the Danish fleet was not defeated at once, but it was also entangled and difficult to get out, which nearly 20,000 Danish troops were besieged in the northernmost unnamed harbor of Jutland, unable to advance or retreat, and were forced to surrender in desperation.

In just over 8 days, the Prussian Fifth Army occupied all of Jutland, this achievement, as the commander, Prince William was also very shocked, to be honest, even he couldn't believe that this was true, he didn't know whether the Prussian army was so powerful all of a sudden, or the Danish army was really so vulnerable.

And Prince William was accompanied by a Chinese, but Zeng Jize had just arrived from the island of Ireland half a month ago. Guo Songtao left Prussia and went to the Ottoman Empire, Zeng Jize came to Prussia, coordinated in the middle, and observed the war launched by Prussia by the way.

"Report, Your Royal Highness the Prince, His Royal Highness Prince Albert led the navy to defeat the Danish fleet in the waters south of Sams Island, and the Danish navy was defeated and fled to the mainland of Zealand, His Royal Highness Prince Albert asked His Royal Highness the Prince, whether to send troops to pursue?" A correspondent arrived to ask for military orders.

Prince William did not answer the correspondent directly, but turned to the staff officer next to him and asked: "Have the Danish infantry units on Jutland been completely cleared?" ”

"Back to Your Highness, all of them have been cleaned up, they have all been disarmed, and they are being taken into custody." The staff officer hastened to answer.

Only then did Prince William say to the correspondent: "Prince Albert is instructed to lead the naval fleet to capture all the other islands of Denmark except for the island of Zealand, and there is no need to defend it, and it is enough to maintain the superiority of the sea area and be vigilant."

In addition, the Fifth Army left 10,000 troops to defend the west and north of Jutland, and the remaining 40,000 soldiers immediately regrouped and withdrew to the port of Kiel in three days. From there, hop on the train and head back to Berlin for the frontline battlefields of Saxony and Bohemia! ”

Prince William's order surprised Zeng Jize.

At this moment, the Fifth Army Corps was distributed in the northern and central parts of Jutland such as Aalborg and Aarhus, hundreds of kilometers or even two hundred kilometers away from the port of Kiel, and in order to arrive in three days, it was necessary to march urgently day and night.

Moreover, the most important thing is that Prince William's order behind him turned out to be to quickly rush the main force of the Fifth Army to the frontline battlefield in the south, which made everyone feel that they were delirious and that time and space were reversed. A few days ago, the northernmost Jutland Peninsula attacked Denmark, and a few days later appeared on the Bohemian battlefield, and Marshal Ron and they attacked Austria and its allies together.

It's just that this marching speed, can you be in time?

"Your Royal Highness, we rushed from Jutland to the Bohemian battlefield, and did we still have time to take part in the battle with the Austrian army there?" Seeing that Prince William had completed the order and was about to pack up and go on the expedition, Zeng Jize hurriedly took the time to ask.

Prince William replied casually: "It should be in time!" All you need to do is make a hasty march to the edge of Kiel Harbour. From the port of Kiel, there is a railway line that runs south through Hamburg and Berlin to Dresden in Saxony and east to the Silesian border. We, the Kingdom of Prussia, have been planning for this day for a long time, spending huge sums of money to build a criss-crossing railway line to transport troops, and a telegraph line in all directions to transmit orders.

Dear Mr. Zeng, you may not know that since two days ago, the 1st to the 4th Corps of our Prussian Army, which has been led by commanders led by Marshal Ron, has attacked on all fronts, raiding both Saxony and Bohemia. Therefore, the fighting on the front line is very fierce, and if our Fifth Army can rush to the front line, although it is only 40,000 troops, it will be a very strong force. It can give great morale and confidence to the allies, and destroy the will of the enemy. ”

Zeng Jize nodded and carefully wrote down what Prince William said.

Prince William didn't care about talking about it, so he hurriedly set out with his army and led his troops to the southern battlefield.

In fact, as Prince William said, as early as two days earlier, the Prussian army had made a surprise attack, attacking directly south without declaring war:

Prince Frederick Charles led the main force of the Prussian Army, the 85,000 men of the First Army Corps known as the East Prussian Army, to advance from Senftenberg and Görlitz to eastern Saxony, and directly attacked Dresden, the capital of the Kingdom of Saxony;

The 3rd Army (Elbe Army) led by Field Marshal Karl Shiffaf von Biedfeld with 40,000 men attacked Torgau in the Kingdom of Saxony and, after a slight build-up, attacked Dresden, the capital of Saxony;

General August Karl von Goebben led the 4th Army (Rhine Army) with 60,000 men to cross the Sudetenland on the border of Saxony and Silesia as the vanguard, directly capturing the Bohemian military town of Koenigretz.

Field Marshal Ron personally led the main force of the Prussian Army, the Second Army of 80,000 men named Brandenburg's Corps, to assemble at Niels in Silesia, and also attacked Bohemia in the southwest. The targets were Prague, the capital of Bohemia, and Vienna, the capital of the Austrian Empire further south.

And just three days later, just as Prince Wilhelm arrived in the port of Kiel and was about to transfer to Berlin by train, an urgent telegram from the front line reached him: the Kingdom of Saxony is completely occupied! The day after the outbreak of the war, the 80,000 troops of the Kingdom of Saxony were quickly routed, although there were few casualties, but more than 10,000 were captured, and the remaining Saxon army of less than 60,000 was forced to retreat into Bohemia to stop the defeat with Austrian protection.

The Austrian Empire was very slow to react. It was not until the army of the Kingdom of Saxony was defeated and the capital city of Dresden was abandoned that the Austrian Empire seemed to understand that Prussia had suddenly attacked and started the war, so it hurriedly mobilized its troops to the border between Bohemia and Saxony to support, and at the same time, the Austrian Emperor issued a statement calling on other members of the German League to denounce Prussia's aggression.

In this way, a few days after the assassination of the Tsar led to civil strife in Tsarist Russia and Prussia invaded Jutland in Denmark, Prussia brazenly launched an invasion of Saxony and Bohemia, aiming the war directly at the Austrian Empire.
