In the midst of the ever-changing situation, many times, a very accidental thing often estimates the impact.

On August 1914, the German Navy light cruiser "Magdeburg" was mine-struck and sunk in the Baltic Sea, and the German sailors drifting at sea were discovered by the Russian Navy, and the Russians immediately announced: "Magdeburg" was sunk by the heroic and fearless Russian Navy. In order to confirm their success, a Russian diver dived to the bottom of the sea to search for the wreckage of the German cruiser, and in the underwater hull, the diver found the body of a German lieutenant, holding only a sealed metal box, which the diver took out of the water out of curiosity. When people opened the box, they found that the box actually contained the password and signal book used by the German ship, as well as a square area map of the North Sea. Copies of these things were immediately sent to the Allied Britain, and after trials, the British Navy discovered that they had been able to decipher the classified radio communications of the German Navy - the British quickly set up a secret service called the "Mole" to intercept and decipher the radio communications of the German Navy, in addition, they used radio receivers to determine the location of the sending enemy ships.

This coincidental "Magdeburg Fortune" soon showed its value in the Battle of Dogger Sandbank on 23 January 19151, when Vice Admiral von Hipper, commander of the First Reconnaissance Fleet of the German Navy's Ocean Fleet, led three battle cruisers and one destroyer out of Wilhelmshaven and headed straight for the Dogger Block, intending to take a knife at the British fishing boats there - and if possible, eat a few destroyers and other "knick-knacks" that came to the rescue.

The British Admiralty had accurate information through the "Mole", and Jericho immediately made a decision to send Vice Admiral Betty's battle cruiser force to intercept the German ** ship, and the main fleet would move later. Attempting to swallow the ground battlecruisers of the High Seas Fleet with a knife and killing chickens.

The Betty fleet consists of 4 powerful "Lion"-class battlecruisers - "Lion", "Tiger" and "Celestial Princess", 2 "Indefatigable" class battlecruisers - "New Zealand" and "Indefatigable", as well as 7 light cruisers and 35 destroyers, which is far superior to the Hipper's fleet.

In the early morning of January 24, the two fleets met unexpectedly near the Dogger sandbar, and the Betty fleet swooped down on the Hippel fleet at a high speed of 27 knots, and Hipper saw a huge disparity in strength - the battlecruiser 35 large-caliber guns 2840, .:.+|. The armored cruiser "Blucher" held back the Hipper fleet, and Hipper was unwilling to give up the "Blucher" easily, but wanted to take the opportunity to test the actual combat effectiveness of the British battle cruisers, so he ordered the fleet to turn to the attack.

After half an hour of fierce fighting between the two sides, a large explosion occurred in the rear turret of Hipper's flagship "Seydlitz", and the fire once engulfed half of the ship's hull, and Betty's flagship "Lion" was hit by three shells in a row, the cabin was flooded, the speed plummeted, and it temporarily withdrew from the battle. The short-legged "Blucher" was paralyzed on the surface of the sea by intensive artillery fire. Hipper had to abandon it and lead the other ships to evacuate at full speed towards Helgoland Bay.

Rear Admiral Moore, deputy commander of the British fleet, left the immobile "Blucher". Lead the team to continue the pursuit. Soon, a group of "Dujuan" attack planes from the aircraft carrier unit of the main fleet arrived on the battlefield and dropped nearly 20 torpedoes on the dead fish-like "Blucher", hitting nine of them, and soon the displacement of this ship was as high as 17200 ~: the bottom of the sea.

Hipper's fleet fought and retreated, but in any case could not escape the faster British war patrols, and the "Seydlitz" was hit by many bullets, and the deck was getting closer and closer to the waterline, and the speed fell again and again, so that it could not move.

Betty, who switched to the "Celestia" to catch up, ordered the "Seydlitz", which was almost paralyzed, to be spared. Continue the pursuit of the two German battle cruisers "Moltke" and "Von der Tann" 42, 32 135-inch and 12-inch guns against 1811-inch guns, 27 knots formation speed against 24 knots top speed. The outcome of the battle should have been one-sided, but the German ship gave Betty a wake-up call with unusually accurate artillery fire - the ammunition depot of Rear Admiral Moore's "New Zealand" suddenly exploded after several bullets, and the whole ship was instantly broken in two. In just two or three minutes, he completely disappeared from the sea with nearly a thousand crew members.

Betty was unmoved, and ordered the fleet to continue the pursuit, first hitting the "Moltke" everywhere, all the main guns failed, and then the "von de Tann": = slower than the turtle......

At this time, in order to cover the evacuation of the battle patrol, the German destroyer forces swarmed up in an attempt to drive back the British ships with dense lightning strikes, but were driven back by a burst of fierce blows by the destroyer forces in which the British army was dominant.

During this period, the British carrier-based aircraft fleet searched for the "Seidlitz", which had lost all power, drifted with the waves, and was in flames, and fired more than 20 torpedoes at it, hitting 13 of them, and the "Seidlitz" quickly capsized and sank, and Vice Admiral Hipper was martyred with the flagship.

By the time Jerichodi's main fleet arrived on the battlefield, the Moltke and von der Tann, though still floating on the surface, had lost most of their firepower and had become "bellies ready to be slaughtered."

Jericho quickly cleaned up the battlefield, he didn't use all 24 battleships + the remaining German ships, only sent 4 "Elizabeth Battleships and 16 Large Destroyers" of the 5th Column Squadron, the 15-inch main guns of the Queen-class and the inch torpedoes on the large destroyers, and it didn't take much effort to dismember the two dead fish. ”

Finally, when a German airship arrived on the battlefield to reconnoiter the battle situation, two "SEAL Cub" fighters that took off from the aircraft carrier "Hundred-Eyed Giant" exploded it into a huge and dazzling fireball with several incendiary bombs.

The Battle of Dogel Sandbank came to an end, the most elite 3 battlecruisers and 1 armored cruiser of the German Navy were destroyed, 2,961 generals under Vice Admiral Hipper were killed, captured and missing, and the British battle cruisers were sunk and wounded, with 1,137 casualties and missing.

In the face of this tragic defeat, the Kaiser, on the one hand, dismissed Admiral Ingnoll from his post as commander of the High Seas Fleet and replaced him with the more modest Chief of Naval Staff, Admiral Bohr, and on the other hand ordered large ships not to sail beyond 50 nautical miles of the Gulf of Helgoland without his approval, and more than a dozen of them had retreated through the canal to the port of Kiel.

On the British side, this glorious victory gave Churchill a decisive decision......
