Here is the improved and more literary translation of your paragraph:
On the streets of Berlin, a convoy of trucks sped recklessly. Within these vehicles were soldiers of the Imperial Guard, fully armed and resolute. Yet, these soldiers no longer pledged their loyalty to the Emperor.
The trucks came to a halt outside the gates of the Imperial Palace, and swarms of guardsmen descended swiftly.
The palace sentries, realizing something was amiss, called out sternly, "Who are you? What is your purpose here?"
But the only response was the crack of rifle fire.
"Bang! Bang!" The sharp sounds of gunfire rang out, cutting through the stillness of the night and carrying far into the distance. The echoes reached even the furthest corners of the palace, sending waves of alarm rippling through its halls.
"Quickly, move faster! Secure the palace, sever the telephone lines, and search every room. Leave no stone unturned—ensure no one inside can communicate with the outside!" General Prittwitz, commanding in person, urged his troops on.
A tide of rebels flooded the palace, commencing a ruthless search.
In the heart of the Imperial Palace, the number of Imperial Guards assigned to its defense was minimal. No one had believed such an event would unfold. The Emperor's residence, the very symbol of the Empire, seemed impervious to attack. Moreover, with Imperial Guards stationed throughout Berlin and its surrounding areas, Kaiser Wilhelm II had always felt secure. Tragically, however, it was precisely the Imperial Guard that had turned against him.
The generals commanding these guards were among Wilhelm's most trusted confidants, his close friends. He never once considered that they might betray him.
The primary orchestrator of this betrayal, however, was none other than the Crown Prince Wilhelm. If his own son could turn against him, then how could he trust anyone else? Furthermore, with lavish rewards from the Crown Prince securing the loyalty of many, those of weak resolve had naturally abandoned their allegiance to the Kaiser.
The few loyal guards still remaining to Wilhelm had already been disarmed. As soon as the rebels struck, their forces had swiftly breached the barracks, catching the soldiers completely unprepared. In no time, the capital was firmly under the control of the insurgents.
Seeing his troops breach the palace gates, General Prittwitz could not suppress a satisfied smile. Tonight's operation had gone off without a hitch. It seemed success was within their grasp.
While the palace was under siege, the Navy and Army General Staff were also targeted. However, Admiral Tirpitz, the Navy Minister, had not been in Berlin; he had gone to Wilhelmshaven, where the German Navy was preparing to assist the army in an imminent invasion of Britain. With many critical matters to oversee, he had narrowly escaped the storm.
Army Minister and Chief of the General Staff, von Falkenhayn, however, was still at the headquarters. When the rebels launched their assault, there was no preparation. The defending guards were swiftly overwhelmed. Soon, von Falkenhayn and the other senior officers of the German Army had been captured by the insurgents.
The mastermind behind the attack on the General Staff was none other than Moltke. After being dismissed, he had left the headquarters in disgrace. Now, he was returning—but not in the manner he had once imagined. Though the means of his return were far from dignified, he found comfort in knowing that, once the Crown Prince ascended the throne, they would no longer be rebels, but victors.
"Count, I never thought I would see the day when you would lead a mutiny!" Von Falkenhayn exclaimed, his face a mixture of shock and fury upon seeing Moltke.
"Falkenhayn, I suppose you never thought your day would come either?" Moltke replied with a wry smile.
"Count, your conspiracy will fail. Even if you capture Berlin and imprison His Majesty, you will still be defeated. The army led by the Crown Prince will easily crush you," von Falkenhayn declared, his voice firm.
Moltke's brow furrowed. Indeed, their forces were still too weak. Should Qin Tian lead the army back to the capital, it would surely be no challenge to crush them utterly.
"Falkenhayn, you need not worry. We already have a plan for dealing with Prince Oscar," Moltke responded with a smile.
"Very soon, His Majesty will send a telegram to Prince Oscar, ordering his return to Berlin. When he arrives, the Emperor will issue a decree to depose him as Crown Prince," Moltke continued.
Falkenhayn's face paled as he realized the danger. If Qin Tian remained unaware of the unfolding events in Berlin, he would be easily deceived, leaving the fate of the Empire in Moltke's hands.
"You will not succeed. God will protect the Crown Prince!" Falkenhayn proclaimed loudly.
"Seize our Chief of Staff and lock him away, under strict guard," Moltke commanded.
Von Falkenhayn and the other senior officers of the General Staff were promptly arrested and confined to a meeting room.
Moltke stood in the office that had once been his, looking out towards the Imperial Palace.
"God help us. I hope everything proceeds smoothly," Moltke murmured. Though he was confident that all their plans had been set in motion, a lingering doubt gnawed at his heart. Beyond the Imperial Guard, their power relied heavily on the Fourth Army Corps under Duke of Württemberg. However, there was no guarantee that the Duke's forces would remain loyal. In contrast, Qin Tian commanded a vast, formidable army. If news of their coup were to leak, the consequences could be catastrophic.
Inside the Imperial Palace, the rebels had already infiltrated. With a few guards at his side, General Prittwitz entered the palace.
In days gone by, when his relationship with Wilhelm II had been close, he had often received invitations to dine with the Emperor within these very walls. But ever since Qin Tian had become the Crown Prince, such privileges had been denied him.
Now, however, as he stepped back into the Imperial Palace, General Prittwitz could not help but feel a deep sense of satisfaction.
"What's happening?" When the gunfire erupted, Wilhelm II awoke with a start. He quickly reassured the Empress, threw on his robe, and rushed to the door.
"Your Majesty, the palace is under attack by unknown armed assailants," his butler, Essen von Jonalett, reported anxiously.
"What? Unknown assailants? How could the palace be attacked? This is the Emperor's residence, the capital of the German Empire. Where are the Imperial Guards? What are they doing?" Wilhelm II bellowed in fury.
