Because of the defeat last time, Mosingen was indeed a lot more careful this time. Moreover, having learned the lesson of being flanked by the enemy's cavalry last time, Mosingen also brought a lot of wheelbarrows with him this time, which were used to block the impact of the enemy's cavalry in formation.

However, in the desert, the wheelbarrow is very difficult to walk. Because the sand is too soft, the wheels are prone to sagging. Fortunately, a capable carpenter under Governor Cotton of Laayoune modified the wheels to create wide ones. In this way, the wheelbarrow will not easily sink into the sand in the desert.

In addition, in order to reduce the physical strength required for the cart, the wheelbarrows brought by Mosingen this time did not carry anything too heavy, except for the four spears on the cart to resist the impact of the war horses, and each cart did not carry more than 200 pounds of goods. Moreover, most of these goods are water......

These are freshwater that has been sterilized at high temperatures and does not deteriorate easily. The method of high-temperature disinfection is very simple - that is, after filling the fresh water into the skin bag, it is directly thrown into the cauldron and boiled. Of course, the wooden stopper of the water bladder cannot be tightened. Because, the heat expands and contracts coldly, and the water bladder after boiling is easy to burst. Therefore, the mouth of the water bladder will be clamped by a clamp and lifted above the water surface of the steamer. When the steamer is boiling and the water in the water bladder is almost sterilized at high temperature, then let the worker wearing leather gloves pick up the water bladder with a clamp, and quickly plug the mouth of the bag with a cork and plug it tightly. Then, put some mud on it and tumble dry. In this way, a bag of water that can be stored for several months without spoilage is processed like this......

This time, Mosingen brought a total of 400 Yu Dayou's wheelbarrows with spears, wide-wheeled ones. On the march, Mosingen would take an additional 400 slaves with him, and he would follow the 800 cavalry and 100 musketeers in the desert with this broad-wheeled wheelwheel. There wasn't much on the wheelbarrow, but it was all very important food and water. Moreover, food can be replenished as it passes through the oases that replenish fresh water.

According to the principle of the desert march, Mosingen demanded that the specially treated fresh water should not be used if it could not be used. When passing through areas where fresh water can be replenished, try to drink fresh water that is available locally. Of course, it is cooled by boiling water in a large pot. Only when walking in the depths of the desert and really unable to replenish fresh water can you use the water bag on the wheelbarrow.

In fact, this wide-wheeled Chinese wheelbarrow was not only used by Mosingen to transport fresh water and to defend against enemy cavalry, but was also intended to be used to transport black slaves in the future.

Of course, it is somewhat inappropriate to say that it was "transporting" black slaves. Because, Mosingen's plan was to let the black slaves push their own wheelbarrows with fresh water. In this way, there was no need to tire the camels to help carry the fresh water needed by the black slaves.

The price of black slaves in the Songhai Empire was very cheap, and a small bag of salt could be exchanged for a strong and honest black slave, which was much cheaper than the black slaves of the Portuguese. But the problem was that it was very difficult to cross the Sahara Desert with black slaves. The challenge was how to transport the fresh water needed by the slaves.

If the camel were to carry the water in the traditional way, the burden on the camel would be very heavy. Moreover, you can't bring many black slaves at one time. After all, camels have a limited capacity to carry up to 300 pounds of stuff.

And let the black slaves push the cart themselves, it will be more convenient. They pushed their own wheelbarrows with what they needed to eat and drink, and they didn't have to work their camels. As many wheelbarrows as there are, you can bring back as many black slaves as you can.

In the past, it was difficult to cross the desert because there were no unicycles with wide wheels. However, since Cotton's great carpenter, Collier, invented this wide wheel that could move freely across the desert, it was no longer difficult for the wheelbarrow to carry things on the desert. As long as you don't pack too many things, it's hard to get stuck in the sand. For example, a Chinese-style unicycle that can hold five or six hundred pounds can only hold more than two hundred pounds, so that people can push it easily and it is not easy to fall into the sand.

In addition to this, Mosingen also came up with a trick - that is, the black slaves were chained to the wheelbarrow. In this way, there is no need to worry about black slaves running away in the middle of the night. Mainly, in the territory of the Songhai Empire, those black slaves are easy to take advantage of the unpreparedness and run away quietly in the middle of the night. After all, most of them were unlucky people in the neighborhood, prisoners of war or forcibly taken into slavery by the nobles of the Songhai Empire. As long as they left the territory of the Songhai Empire, those black slaves became honest. After all, not locals, dare not be arrogant......

……

However, on this expedition, Mosingen did not want to bring many black slaves, but brought a group of slaves himself to help push fresh water, a strategic material in the desert, in order to cope with the possible outbreak of fighting in the desert. Moreover, these slaves were also simply trained in combat. If necessary, you can also draw one of the four spears from the car, hide behind the car, and poke the enemy's scimitar cavalry with the spear.

But that was usually an emergency, and Mossingen didn't think his 800 Mamluk slave cavalry could defeat the cavalry of the bearded North African merchants. Because, those scimitar cavalry, most of them were irregular tribal cavalry, and they seemed to be brave, but in fact they were far inferior to those Egyptian slaves who had received regular Mamluk cavalry training.

What's more, in the past few months, Mosingen has also trained these Egyptian slaves who have been trained in Mamluk cavalry in discipline and tactics, making these slave cavalry more disciplined than the authentic Mamluk cavalry. In the words of the Emperor, the level of team combat of these Egyptian slave Mamluk cavalry was no worse than that of the authentic Circassian Mamluk cavalry. They may not be the opponents of the authentic Mamluk cavalry in individual and skirmishes, but they are outnumbered, and they are no worse than the authentic Mamluk cavalry, relying on the discipline and formation they have repeatedly trained over the past few months.

As for the Arab tribal cavalry led by the bearded men of North Africa...... Just ask if you are afraid of the Egyptian Mamluk cavalry who can charge against the wall......

In order to facilitate the direct stabbing during the wall charge, all the Mamluk cavalry from the Egyptian slave background were changed to use relatively straight Type 65 cavalry knives, which could stab and slash. Although they were a little unfamiliar at first, these people were also trained for many years, proficient in a variety of weapons, and even learned the use of European knights' straight swords, so it was not difficult to get started. Over the course of a few months, the 800 Egyptian Mamluk slave cavalry had adapted to the use of Type 65 cavalry sabers.

Completely crushed in terms of personal force and tactics, Mosingen did not think that these 800 men would lose to the one or two thousand bearded North African tribal cavalry......

You know, in history, Austria has never lost a cavalry duel to Turkey since it learned to launch a wall charge with a knight's straight sword. And the Austrian cavalry of the 18th and 19th centuries could only be considered second-rate in Europe, inferior to the French cavalry and the Prussian cavalry. Even, not necessarily the cavalry of Tsarist Russia......

However, they are the traditional scimitar cavalry that can abuse Turkey, and since then they have beaten Turkey, the "European bulldozer", into a local chicken......

Of course, it was not the Austrians who really brought Turkey into decline, but the fierce Tsarist Russia. Starting from Peter the Great, Tsarist Russia launched a number of Russian-Turkish wars in succession, and brutally crippled Turkey, the "European bulldozer".

But it is undeniable that Austria, which had been besieged by Turkey many times in Vienna, since mastering the wall charge, no longer had the upper hand in the conflict between the Balkans and Turkey, but began to take advantage......

However, Austria was too busy annexing Italy and competing with Prussia for the position of the German boss that it did not have the energy to engage Turkey. Later, he finally realized the reality, abandoned Italy and began to turn around and annex the Balkans, only to be defeated because of the assassination in Sanajevo, which triggered the First World War......
