Unlike the ordinary shooters in the new guard battalion, the 500 or so officers and men in charge of the recoilless gun mounts were able to effectively communicate with the reconnaissance hot air balloons and use more effective archery skills when the troops were advancing because they were more fully trained and specialized.

Therefore, in the first firing in the advance, 2,000 recoilless cartridges loaded with ammunition were first used as Franco-style sub-guns to fire and focus on attacking the front row of the besieging enemy, and to a certain extent, form a side fire.

It is different from the previous attack on a target that is close to a distance of about two miles. When firing at a target of about a mile, tens of thousands of joules and even a pound of steel bullets with strong momentum almost indestructibly destroyed the vast majority of shields and even car shields that were trying to effectively resist, and 2,000 black powder shelled steel arrows once again caused about 15,000 casualties when facing targets dominated by heavily protected infantry and cavalry.

Almost at the same time, 200 medium field guns, which had been firing one after another, also opened fire with more than 100,000 heavy shotguns, killing and wounding thousands. After the main force in the front row suffered another blow and casualties of significantly more than 10%, the entire Ottoman army began to gradually retreat again.

At this time, with the help of the effective command of the reconnaissance hot air balloon, the gunners of the new guard battalion began to continuously use the other auxiliary gunners to fill the forehead canisters and launch a continuous firepower again, but the focus of the attack was not on the targets in the front row or the front part, but on those elite forces behind the enemy line.

Perhaps because of the distance, the casualties caused by the 3,000 or so steel arrows again were less than 10,000, but such a blow undoubtedly signaled to the enemy that even at this distance, there was no safety at all. The elite forces of the Warlords and the Suppressors are not safer than others just because they are further behind.

And it was at this time that the momentum from the retreat in front also began to act on the back. Under the continuous firepower, the Ottomans, who had paid a total of about 60,000 or 70,000 casualties from the beginning to the end, completely lost the determination and courage to continue fighting, and even lost the courage to continue to carry out the encirclement mission, and continued to retreat backwards.

Xiao Xuan also did not give the order to waste firepower and spread fire in a farther direction. After all, because of the total number of people and even the cost, the recoilless gun with high combat effect is something that Xiao Xuan also needs to pay attention to the amount of ammunition and the duration of firepower.

Of course, after the rout of the Ottoman army as the main body, because the difference in strength between the two sides was too large, there were still some enemy troops who had better luck in the previous battle and felt that the victory of the previous opponent may be largely just the reason for the three-board axe, and if they continue to stay and persist in fighting at this time, they may be able to have a better effect?

However, at this time, more than 200 fireloads belonging to Baotou steel breech guns that continued to fire with fierce shotguns in just a few minutes, and hundreds of thousands of shotguns fired hundreds of thousands of shotguns in more than ten rounds of fire in just a few minutes, brought serious pressure to the remnants of the enemy in the distance, and finally caused the only remaining Ottomans on the battlefield to gradually retreat.

At the end of the day, the massive Ottoman attack only left the corpses of more than 100,000 horses and even 70,000 soldiers on the battlefield. The size of the Ottoman horses captured in such battles, and even after simple identification, they were not wounded and were barely usable, and the size was about thousands. There are also a lot of baggage vehicles and even artillery left behind by the Ottomans.

If it was during the first expedition to the west before, perhaps Xiao Xuan would have thought of making effective use of these artillery pieces and ammunition. After all, the gunpowder, ammunition and even armor of the Ottomans can be regarded as high-grade according to the standards of the previous Ming army. However, at this time, for the current new guard battalion and its affiliated forces, it has completely risen to another level in terms of firepower and equipment strength. It probably only cost about three or four percent of high-grade ammunition, and the main force of the Ottomans was easily routed in this situation.

Xiao Xuan did not decide that the expedition would end there, but after repelling the siege of the main Ottoman force, he quickly launched an overland attack along the Black Sea coast against the Ottoman Turkish mainland. Although it seems that there is no absolute certainty in the previous operations that the high-quality ammunition carried by the Ottomans will kill the remnants of the entire Middle East generation, according to Chen Xin's rough estimates, this is mainly due to the lack of understanding of the nature of the Ottoman armed forces. If the most suitable artillery shotguns were used to carry out the attack, and if the attack was more daring in the attack, and the attack was carried out at a closer distance rather than a mile or two, the consumption should be much less.

Although the whole army is equipped with a lot of artillery, mules, horses and even baggage, but because the total strength is not large, the logistical problem is much simpler than that of an army of tens of thousands to 100,000 people, using some improvised small boats that can be easily inspected as auxiliary means of marching and logistics, even if some terrain on the Black Sea coast does not seem to be suitable for the passage of too large an army, there is no major obstacle for the army of thousands of people after all. In the winter months after the autumn harvest, it is much easier to obtain provisions by plundering in situ.

In this way, after about a month's march, Xiao Xuan's team made a detour from the eastern shore of the Black Sea to a place near the Ottoman hinterland and began to advance. During this period, they also encountered many local armed forces and forces that tried to resist, but most of them were only a small force ranging from a few thousand to 10,000 people, and often almost some of the troops were able to defeat the opponent in a single round of fire. Perhaps the previous battle was too much of a blow to the enemy, and after the previous defeat, the Ottomans' heavy army group did not seem to dare to face the army, but could only avoid it as much as possible.

It was not until the army led by Xiao Xuan approached Ankara in the hinterland that it had long been concentrated here, and after replenishing a lot of local armed forces, the main group of Ottomans, whose total strength had been re-expanded to about 200,000 people, finally formed a joint force with the reinforcements of the Safavid Dynasty.

In fact, the Safavid Dynasty was also hesitant on the issue of whether to deal with Xiao Xuan's headquarters, but the team led by Xiao Xuan went deep alone with a small team after just experiencing a major war, which gave many people confidence.
