It wasn't until the Dionian Frontier Legion stationed on the Etruscan border and began to contain the frequent attacks of the Senones that they realized that the new force that had emerged in northern Italy was not as weak as they thought, but they believed that it was mainly because the raids were organized by the tribes themselves, and the main focus was on raiding, and there were no special personnel to deal with the Dionian attacks.

However, the fact that the Dioonians assisted the Etruscans in defending the border attracted the attention of the Senones, who feared that the strengthening of the alliance between the Dioonians and the Etruscans would cause problems for their southward invasion, so they originally wanted to wait for a few years before fully recovering their strength before moving south, but now the sudden change in the situation forced them to act in advance. Just in case, the Senones persuaded the Knomenes to go south with them.

Since this invasion was larger than the last, the Gallic chieftains were full of confidence, and after more than a year of fighting, they knew that the Dionians' barracks were well defended, but they were not numerous, so they made a special effort to bypass them during the raid.

At first, the attack went very well, capturing Florentia and Arettitum in succession, but then they suffered a disaster, and the main invasion forces of the Senones and Knomani were routed by the Dionian reinforcements, and under their non-stop pursuit, the remnants of the defeated Gallic army could not organize effective resistance at all.

In the terrible situation of interception in front and pursuers, the remnants of the demoralized Gallic army were either crushed, killed or captured, or fled into Vernorentia and Aretium in a hurry, and then were surrounded by the Dionian army, and only some of the soldiers escaped into the mountains.

It didn't take long for the Gauls in the territory south of the Po River to learn the news of the "crushing defeat of the Gallic army going south", they were very panicked, they were not worried that their territory would be attacked by the enemy, after all, since the Gauls settled here for a hundred years, they have always invaded others, and no other race has ever dared to invade their territory, they are relatives who are worried about life and death in Etrunia, so the elders of Senonese and Knomani gathered to discuss and decided to ask Salves for help, He begged him to send an army to Etruscan territory to rescue the besieged and captured Gallic people.

While the three tribal leaders were discussing, early in the morning, the slaves of Weavei who lived in the city of Amirium were going out to sea to fish with fishing boats, but suddenly saw countless huge warships appear on the sea in the distance, although they had occasionally seen one or two similar warships sailing over the sea near Arminium City, knowing that they were the warships of the Dionian Kingdom in the south, but this time the number of warships was so large that they covered the entire sea, which really frightened them at a loss.

Heading for the coast near the city of La Aminium, it was the battleships of the First Fleet of Dioonia laden with legionnaires.

Since the last war, except for the Kingdom of Dionya itself, there has been no maritime power in the western Mediterranean, so under the instructions of King Davers, the Ministry of War has reorganized the Dionian navy, from the original 4 fleets to 3: the 1st Fleet is mainly stationed in Brindisi, and the other naval base is in the port of Tarantum, which is responsible for defending the waters of the east and south coasts of Italy, and at the same time monitoring the eastern Mediterranean.

The 2nd Fleet, with its main base in Liliba and another naval base in Catania, was tasked with defending the waters of Sicily and monitoring the waters of Africa, and its fleet commander was Midorades;

The 3rd Fleet, with its main base in Alenia and another base in Trina, oversaw the security of the seas off the west coast of Italy, Corsica, and Sardinia, and guarded the remaining western Mediterranean seas.

Among them, the 1st Fleet was the strongest, with a total of 550 warships; The 2nd Fleet was slightly smaller, with a total of 500 ships; The 3rd Fleet was the weakest, with 150 ships. This is mainly based on the tasks they undertake, the strength of the enemies they may face.

The reason why the number of warships in the Dionian Navy has increased a lot is mainly because in the early stage of the Western Mediterranean War, both Dionya and Carthage, which were seriously damaged by the navy, were stepping up the construction of warships in order to gain maritime superiority.

However, after Carthage surrendered to the Kingdom of Dionia, some Phoenician city-states also joined the Ionian League one after another, resulting in the Kingdom of Dionya having no enemies in Africa, and the reduction of the Second Fleet was already under the consideration of Davers and the Ministry of War.

At this moment, one after another Dionian warships quickly passed by the already frightened fishing boats of Veneti, and approached the flat beach in front of them, and thus began what became known as "the most terrible day of the Gauls of the mountain......

…………………………………………

The day before landing in Gaul, the envoys of Dioonia sent to Liguria and Veneti one after another.

The Veneti were more interested in attacking the Gallic territory, but the ferocity of the Gauls apparently left a terrifying memory on them, and they finally stated that as long as the Dionian army did not invade the territory of the Veneti, they would not interfere with the actions of the Dionian army, and would also provide them with some material assistance.

The Ligurians, on the other hand, argued over the proposal of the Dionian emissaries and could not reach an agreement: some of the chieftains opposed the Dionian attack on Gaul because it would undermine the existing stability in northern Italy; Others stated that they would not interfere in the Dionian military operations as long as the Dionian army did not enter Ligurian territory; Only a handful of chieftains expressed their willingness to join the Dionian army in attacking the Gauls and thus capture some fertile land......

Regardless of the response of the two races, the Dionian army set sail at Brindisi as planned, and after two days and two nights of sailing, landed on the coast near Alimium, and immediately captured the unsuspecting city of Alimium, followed by a rapid westward advance.

The Dionyse army was overwhelmed along the way, capturing the cities of Boloma and Parma, and then the army turned north and approached Cremona (now Cremona), at which point the Señez hastily gathered all the young and middle-aged people about 10,000 men to defend on the north bank of the Po River, trying to prevent the Dionian army from continuing northward, and at the same time urgently asked for help from the Salves and Knomani tribes.

Leoticides led his army to camp on the south bank, and ordered all engineering battalions to speed up the construction of bridges and prepare for the crossing of the river, and at the same time sent troops down the river in an attempt to cross the river in an alternative location.

While preventing the Dionian army from building bridges near Cremona, the Senones also sent troops to follow the enemy's movements, and even went so far as to enter the territory of the Veneti, which had some conflicts with the Beneti (the territory of the Beneti was originally in the entire lower Po River, and later the land on the southern bank was occupied by the Sesenonesians).

During the confrontation between the two sides across the river, Salves and Knomani sent as many reinforcements as possible, whether out of comradeship or out of bitter feelings, so that the number of Gallic warriors on the north bank of the Pou River increased to nearly 70,000, and for a time the confidence of the Senones was greatly increased.

At the same time, Patroclus, who had largely wiped out the remnants of the Gallic army in Etruscan, led the Third, Twelfth, and Fourteenth Legions, led by the Frontier Corps, passed through the Lucca barracks, marched first on the seaside road, then trekked through the passes of the valley in the mountains, and finally reached Parma, and then quickly marched eastward, encircling the unguarded Gallic town of Placentia (present-day Piacenza), east of Cremona and on the south bank of the Po River.

After capturing it, the engineering battalion quickly began to build bridges as well. Due to the fact that there are several islands in the middle of the river near Piacentiia, the bridge was built very quickly. It took only a day and a half for the bridge to be built, and Patroclus quickly crossed the Po River with four legions and made it to the central town of Salves, Midiolan.

After the Gauls received the urgent report, they realized that they had been fooled, and hurriedly led their troops to the rescue.

Patroclus stopped his advance when he reached Lodi, a small town halfway through, and ordered his soldiers to rest well and wait for battle.

By the time the Gallic coalition had hurried to Lodi, Patroclus was already leading his army in a line outside the town.

At the same time, the main force led by Leotizides also crossed the river from Piacentia and rushed to the vicinity.

The two Dionian armies, one south and one north, pressed on the Gallic coalition, which was unable to advance or retreat and had to be forced to fight.

Thus began the only battle between Dioonia and Memanouchi Gaul on the Po Plain.

Although some nearby Gauls rushed to join the battle during the battle, the Gallic side was in danger of being flanked from both sides from the outset, and was still far outnumbered by their opponents, but the Gallic warriors fought to the death and even used chariots against the Dionian army for the first time.

Nearly 200 two-horse chariots galloped towards the approaching main Dionian army, trying to disrupt the enemy's dense formation first, and then let the warriors charge with their swords.

However, the Dionian military ministry had already studied the tactics of the Gauls, and Leotizides and Patroclus had also trained in this, so first the light infantry of the legion outside the array attacked the horses carrying the carriages from a distance, and then the phalanx of the heavy infantry quickly turned into a checkerboard array, widening the gap between the detachments, and reserving a passage for the remaining Gallic chariots, so that even if they rushed into the formation, they could not have a great impact on the entire formation, and were quickly eliminated.
