In the middle of the night on July 23, 457 AD, the fleet of Balhan's Marine Cavalry Division quietly arrived at the mouth of the Black Sea in the Bosphorus, and silently tried to approach the naval port of Poiraz in the strait.

A year ago, when Qin Dong used the Persians to blackmail a large number of seamen, shipbuilders and technicians in the Eastern Empire, the Eastern Empire guessed that Qin Dong might want to build a port and fleet on the Black Sea, but the top leaders of the Eastern Empire did not take this seriously, because they knew that the navy could not be built in a day or two, nor could it be formed in a day or two. Officials and noblewomen also made fun of Qin Dong and the barbarism and ignorance of the Huns on various social occasions and banquets, but they did not know that today and tomorrow they would have to pay a heavy price for their carelessness.

"General, the Bosphorus is ahead! There are no patrol ships at the mouth of the strait, and the general's fleet can go straight in and kill them without leaving a single piece of armor," Severus said viciously.

It stands to reason that Severus, as an Eastern Roman, should not unreservedly help Balhan to attack his homeland, but it is a pity that Severus is a very small-minded person who is eager to repay him, he hates the Eastern Roman Empire for giving away these seamen, shipbuilders and technicians to the Hun Empire as goods, since the Eastern Empire does not want them as subjects, then why should he be loyal to this rotten dynasty? Severus's mentality was the same as that of Zhongxingyue, who was once sent to the Xiongnu by the Han Dynasty, and he vowed to help the Xiongnu Empire against the Eastern Roman Empire for the rest of his life. Until the fall of the Eastern Empire.

Standing on the bow of the warship commanding the warship, Balhan looked at the mouth of the strait in front of him like the mouth of the blood of a giant beast, and held the hilt of the sword at his waist and ordered without looking back: "Give orders to all warships." Enter in three formations, forbid anyone to make a sound, take care of the cattle in the cabin, order all the archers to climb the tower and prepare for the attack, carry the rockets as well, and all the warriors wait for my orders! ”

"Yes, General!"

The herald immediately lit a torch and ran up to the ship's arrow tower, brandishing it to convey Balhan's order. If it is during the day, it is generally relied on flags or trumpets to convey orders, but at night the sea breeze is strong and it is invisible. It is not yet possible to make a sound, so the signal can only be signaled with a torch, although there is a risk of exposure, but it is also the safest and safest way.

The Bosphorus is simply a stretch of the Black Sea Strait close to the Black Sea. The Black Sea Strait was also called the Turkish Strait and the Istanbul Strait in later generations. The Black Sea Straits, including the Bosphorus, Marmara and Dardanelles (also known as the Canakkale Strait), have been battleground for military battles throughout the ages and are strategically important.

The Black Sea Strait, known as the "throat of the world", is the only strait leading from the Mediterranean Sea to the Black Sea, with a total length of 345 kilometers, and the entire strait is in a northeast-southwest direction, which is the dividing line between Asia and Europe. The Bosphorus is bordered to the northeast and the Dardanelles to the southwest. Between the two straits is the Sea of Marmara, Turkey's inland sea.

The Black Sea Strait is the only outlet to the sea for the countries surrounding the Black Sea, and the gorge has a Mediterranean climate. For most of the year, the sea is calm, the currents are slow, the beaches and reefs are scarce, and the shipping conditions are excellent, so the sea shipping is very busy. Among them, the Dardanelles Strait is 65 kilometers long, 1.7~7.5 kilometers wide, and 57~70 meters deep. The Sea of Marmara is an inland sea, about 70 kilometers wide from north to south, about 266 kilometers long from east to west, with an area of 11,800 square kilometers, an average water depth of 357 meters, and a maximum depth of 1,355 meters. The Bosphorus Strait is about 30 kilometers long, 3.7 kilometers wide in the northeast, only 747 meters in the narrowest part in the middle, and 27.5~124 meters deep.

Due to the fact that the total amount of atmospheric precipitation and runoff from several large rivers in the Black Sea greatly exceeds the evaporation of the sea surface, as well as the constraints imposed by the outlet of the narrow strait, the sea level of the Black Sea is 50 cm higher than that of the Aegean Sea, while the salinity is lower than that of the Aegean Sea, only about 12. In this way, the surface sea water with low salinity (10~20 meters underwater) flows from the Black Sea to the Aegean Sea, and the deep sea water with high salinity flows from the Aegean Sea to the Black Sea.

Since the Bosphorus is only 747 meters at its narrowest point, in 480 BC the Persian Empire Zexis I (son of Darius I) built a pontoon bridge here and set out for Greece. Alexander the Great, King of Macedon, crossed the strait in this way when he set out for Persia in 334 BC, and it can be seen that despite the wide strait, it could not stop the invaders.

The huge fleet slowly entered the Bosphorus, it was already late at night, there were no ships sailing on the strait, even the small fishing boats on both sides of the strait had turned off their lights, and the fishermen fell asleep, no one knew that a huge fleet had come in.

An hour later, the moonlight and starlight of the moon and stars in the sky of the fleet were able to see the navigation lights in the watchtower and spire in the port of Boiraz, and although the navigation lights could be faintly extinguished at any moment, they could still be clearly seen from a distance.

As the fleet gradually entered the harbor, dozens of Raven warships were moored in the harbor of Poiraz, which were moored in an orderly manner, and the whole harbor was completely dark, except for the lights in the spires of the observation towers that towered into the clouds, and was so quiet that only the faint sound of the sea breeze blowing and the waves lapping against the shore.

"One Rory!"

"300 Rom"

"One Hundred Beams"

Severus kept reporting the distance of the fleet to the Eastern Empire fleet anchored in the harbor, and the more he reported, the more excited he became, as if the Eastern Empire naval soldiers and officers in the harbor had been killed to the point of blood.

When he was about fifty meters, Barhan drew his saber from his waist and shouted: "Warriors of the Great Huns, control the warship and rush over, kill-".

"Kill-kill-kill-"

Three loud roars broke the silence of the whole port, and the port immediately boiled, and the various warships ran out to close the crew, they didn't know what was going on, but they seemed to hear the shouts of the Huns in their sleep, so they ran out of the cabin naked to see what was going on, and when they ran on the plywood, they found that the port was brightly lit, and a large number of strange warships appeared out of thin air, and those warships were rushing over quickly.

Suddenly, the moon and stars in the sky seemed to be obscured by something, and before the crew members who had woken up from their sleep could react, they only heard a "buzz" sound, and realized that the moon and stars were covered by a rain of arrows.

"Ahhh......h

After three consecutive waves of arrow rain, every warship in the entire Eastern Empire fleet was full of arrows, and some powerful arrows were shot into the cabin.

"Bang" "Bang" "Bang......

The soldiers and crew of the Eastern Empire Navy, who were hiding in the cabin and were not injured by arrows, had just escaped the call of death from the brink of death, when they suddenly felt a huge vibration from the entire hull, as if the warship had been hit by something.

The officers and soldiers of the Eastern Empire Navy who reacted quickly immediately knew that the enemy had begun to engage in a white-knuckle battle, and on a ship, an officer of the Eastern Empire Navy immediately shouted: "All the warriors take your spears, shields, and short swords and go out to meet them!" ”

The Eastern Roman naval officer was seen wearing an Eastern Persian tunic and a linen cloak decorated with reddish-purple strips of cloth from the shoulders downwards, a sign of rank. The loose Persian trousers are sewn with a deep purple pattern, and the blouse is fastened from the waist with two cloth belts, which are fastened from the waist with a unique button on the front left side of the body, and a pair of dark red leather boots of the same color as the trousers are placed on the feet.

The sailors in the cabins were dressed in back-wool cloak-style overcoats and Oriental trousers, belts of leather, spears in their hands, and the outer surface of their shields was covered with animal skins.

Under the command of this naval officer, the soldiers and sailors all rushed out of the cabin and fought with the soldiers of the Hun Empire who had just rushed up, after all, the soldiers of the Hun Empire were violent, and the soldiers of the Eastern Empire were in a panic, after a series of casualties, the seamen and soldiers of the Eastern Empire were quickly driven back to the cabin, and the Hun soldiers rushed into the cabin and rushed to the hungry wolf to kill the soldiers of the Eastern Empire who were blocked inside, None of these Eastern Empire navy officers, warriors, and sailors wore armor, and their defensive capabilities were much worse than those of the Huns in cowhide armor.

However, the navy of the Eastern Empire is experienced in the white-knuckle battle, although they were occupied by the Hun soldiers in the first period of time, most of the battlefield was killed, but later, under the command of the officer, the soldiers of the Eastern Empire began to stabilize their positions, because the soldiers behind were wearing heavy armor, and one by one holding swords on the plywood lined up in a neat phalanx, the Hun soldiers encountered such a dense heavy infantry phalanx, and were killed for a while.

"Report - General, the big thing is not good, the rear warships of the Eastern Empire have stabilized their positions, and now they are sending heavy infantry to form a phalanx, our army can not advance at all, and they have been killed and retreated, not only losing most of the previously occupied warships, but also suffering heavy casualties, what should I do next, please show the general quickly!" A herald came to report to Balhan on the orders of the regimental commander at the front.

Balhan frowned, it was the first time he commanded a naval battle, and in the face of such a situation, he really didn't know how to deal with it, so he had no choice but to turn his head to look at Charlie Cao: "Dao Chief, how do you think you should fight next?" (To be continued......)
