Due to the constant wars of the Empire in recent years, either civil wars or battles with the Romans, the Sassanid Empire continued to expand to the surrounding areas after its establishment, so that the trade routes from the two river basins to the Roman Empire were threatened, and the trade routes connecting the east and west had to be transferred from the two river basins to the Red Sea coast, and through the Egyptian provinces or Arab provinces to the Mediterranean coast.

The rise of the Red Sea trade routes brought not only a large number of pirates, but also the rampant piracy forced caravans to take the land route, which brought wealth and prosperity to the cities along the Red Sea coast.

Pirates are an ancient profession.

Now, Gao Shun cut off trade with the Roman Empire, and the trade routes through Palmyra were cut off, which stimulated the prosperity of the trade routes along the Red Sea coast.

The word "Arab" in the Roman population originally meant desert, desert. Often, it can also refer to a region or ethnic group, namely the Arabian desert and the nomadic people who live in the desert.

The arid "tropical desert climate" of the Arab region as a whole is a well-known reality. However, excluding the fertile crescent, the Arabian Peninsula is not all barren land that cannot be inhabited by large populations. As the saying goes, "where there are mountains, there is water", no matter how harsh the overall climatic conditions, mountains are always able to collect more water vapor and form precipitation. Looking at the topography of the entire Arabian Peninsula, the whole presents a three-step shape with high in the west and low in the east. From west to east, it includes: the Sierra Range, the Najd Plateau, and along the Persian Gulf-Indian Ocean Plain. Among them, the highest altitude and relatively good living environment is the "Serat Mountains", which run through the western edge of the peninsula and almost connect with the Red Sea.

Judging from the internal structure of the Cerat Mountains, it shows a trend of "high in the south and low in the north". With the holy place "Mecca" in the minds of the world's best people today, it can be clearly divided into two sections of mountains, north and south. Among them, the southern section has a higher altitude (2000-3000 meters) and a larger volume called "Asir Mountain"; The lower altitude (1,000-2,000 meters) and smaller volume in the north are called the "Hejaz Mountains" (also known as the "Hijaz Mountains"). Obviously, the living environment of the Asir Mountains in the south will be significantly better than that of the Hejaz Mountains in the north.

Not only does the Asir Mountains receive abundant precipitation (1,000 mm per year at the highest altitude), but they also provide fertile soil for their inner valley oases. This has allowed the Asir Mountains to appear in this barren land for a long time as the core agricultural region of Arabia, and thus become the birthplace of Arab civilization before the first era. In contrast, the situation in the Hejaz Mountains is much worse, with almost no seasonal rivers (only springs in the desert). This environment made it a nomadic area like the central and eastern Arabian Peninsula.

It was in this environment that many towns were formed on the eastern shore of the Red Sea, and Gao Shun and others exterminated the pirates in the Red Sea while clearing the towns on land.

Open the system map, all the alien races are extremely clear on the map, sweeping all the way through, and no one can escape.

Gao Shun adopted a policy of extermination, leaving no women and children behind, all of them were killed, wealth was taken away, villages and towns were burned, and the east coast of the Red Sea, within a few hundred miles, became a no-man's land.

Originally, Gao Shun also wanted to build a city here and leave an army, but the local fresh water resources were too poor to support subsequent development, so he gave up this idea.

Over the course of several months, the crowd reached the junction of the Arab and Egyptian provinces, southwest of the Sinai Peninsula, where they landed.

The Romans had long learned that the Han Chinese had overthrown the newly established Sassanid Empire and rebuilt the Sabbatical Empire, and they estimated that it would take at least a few years for the Han Chinese to digest and assimilate, and they were now in civil strife and could not afford to take the opportunity to conquer the Sabbatical Empire, but fortunately there was no threat to the eastern frontier for the time being.

Therefore, the Roman Empire did not defend against the Rest Empire, and the place remained the same.

The alluvial plain in the northwest corner of the Sinai Peninsula belongs to the provinces of Egypt, and most of it belongs to the Arab provinces; The northern contiguous region was originally a province of Judea, but after the rebellion of the Jews was put down, a province of Palestine was established in its area.

Subsequently, Gao Shun released 30,000 high-ranking infantry and 30,000 high-ranking cavalry, and Ma Gui led Zhao Xiong, Cao Shan, Xiang Rong and other four people to conquer the provinces of Egypt and the coastal provinces in the west, all the way to the Strait of Gibraltar.

There were only two Roman legions in that land, and each Roman legion had less than 6,000 infantry and 600 cavalry, plus some local infantry pairs, which were absolutely vulnerable.

The rings of Ma Gui and the others are also filled with food, arrows and other materials, and they can move forward lightly.

This will be the territory of Ma Gui's son from now on, so Ma Gui is extremely concerned.

Gao Wei led the fleet back to blockade the Gulf of Aqaba and cooperate with Gao Shun to eliminate the garrisons of the Arab provinces.

Gao Shun led Qin Guan, Fang Liang, Zhou Fei and other four people to the north, preparing to take the opportunity to conquer the Arab provinces and the Palestinian provinces; The intelligence of the surrounding garrisons has been clearly understood.

The Third Cyrenaica Regiment (legio III Cyrenaica) was stationed in the Arab provinces.

The 6th Ferta Regiment (legio VI Ferrata) and the 10th Freitensis Regiment (legio X Fretensis) were stationed in Palestine.

The Third Gallic Regiment (legio III Gallica) was stationed in Phoenicia, a newly established province in western Syria.

The 4th Scythian Regiment (legio IIII Scythica) and the 16th Flavia. The Legio XVI Flavia firma remained in Syria.

The enemies Gao Shun faced were much stronger than the enemies that Ma Gui and the people he to; But their garrisons are scattered and can easily be broken by each one.

The reason for the battle to conquer this area is because of the geographical advantages of the region, the coast is plain, to the north is the Mediterranean, to the west is Egypt, to the east is the Great Rift Valley of West Asia and the parallel mountains along the direction of the rift valley, and then to the desert; And the rift zone and the Mediterranean form a triangle, the further north, the narrower, very easy to defend, the battle territory here, can form a closed area.

The area where Gao Shun and others landed was Suez in later generations, and Aqaba, the capital of the Arab provinces, was on the other side of the Sinai Peninsula, so Gao Shun and his men bypassed the high mountains, followed the highway in the plains, turned to the road of Trajan, and reached the north of the city of Aqaba.

Aqaba is located at the top of the Gulf of Aqaba at the top of the Gulf of Aqaba, thanks to its strategic location at the intersection of trade routes in Asia, Africa and Europe, and became an important port city and shipbuilding center of the Roman Empire;

Gao Shun released 5,000 high-ranking cavalry and 5,000 high-ranking infantry, surrounded the city of Aqaba, and cut off their escape route by land, while by sea, Gao Wei blocked the bay from which Aqaba departed.

First, cut off the internal and external connections of the city, and force the opponent to go out of the city to face the battle.

The Roman legions were very high, and the honor of the soldiers made them not retreat, and they stayed behind to defend the city with the auxiliary infantry brigade, and the 3rd Cyrenaica Legion all went out of the city to meet them.

This is exactly what Gao Shun means.

However, Gao Shun didn't want to fight hard with his opponent, let alone fight with him.

The Roman legion is known for its well-defended hoplite phalanx (that is, the turtle shell formation of the landlord), the European plain is vast, and its tactics are basically that the infantry relies on the overall defensive effect of the phalanx, gradually advancing, and after the short hand, the phalanx can be constantly changed, dividing and digesting the enemy. This method of warfare dominates Europe, but it has its weaknesses that cannot be ignored, and the marching speed of the phalanx will be slower due to the overall movement.

So Gao Shun asked the cavalry to surround the Roman legions on all sides, constantly harassing with cavalry, and the infantry met the enemy head-on.

After approaching, Gao Shun suddenly released thirty bed crossbows in the rear of the army, and the infantry quickly retreated, making way for space; Thirty bed crossbows fired arrows larger than javelins in turn, and the shields of the Roman legions were shattered and shot through the soldiers behind them.

The tortoise shell array was in disarray, and the sharp arrows of the cavalry came quickly, inflicting great damage on the poorly protected Roman soldiers.

The power of the Romans frightened them, and they were too sharp to resist.

The high-ranking infantry in the rear, with bed crossbows, also constantly fired arrows with bows and arrows to prevent the enemy from resuming formation.

The bed crossbow fired constantly, constantly inflicting casualties on the Roman army.

The Roman soldiers soon could not withstand this blow, and fell into collapse, the formation was disorganized, and some even tried to escape, but they were easily killed by the cavalry.

The war lasted all morning, and the Arab governors had no choice but to surrender, otherwise they would have no escape and would be annihilated.

Gao Shun successfully led the Arab provinces, but also showed him the power of the Roman army.

Gaoshun set up Sinai County here, which would henceforth be owned by the Egyptian Empire.

The city of Aqaba was both the seat of the Sinai County and the main port facing the Red Sea and the seas to the east.

After leaving behind the Taishou and the commander and the defensive forces, Gao Shun and the others continued north along Trajan's Road.
