Mongol invasion of Russia | Battle of the Vozha River 1378

In the second half of the 14th century, the Mongolian Empire became an extremely loose state entity that lost its internal unity. The decline of the Yuan Empire, which was ruled by the descendants of Kublai and of Hulagu, began. Chagatai Khanate burned out in an incessant civil war. Over the 70 years, more than 20 khans changed there, and only under Timur, order was restored. Golden Horde, which included a significant part of Russia, was also not in the best position. During the reign of Khan Uzbek and his son Jani Beg, the Golden Horde reached its peak when the root trade from the Black Seas to Yuan region flourished. However, after the death of Jani Beg in 1357, things spiraled out of control. For almost 20 years, from 1359 to 1381, the Horde was consumed by civil wars. Leaders kept changing, one after another no less than 24 khans, possibly even more, ascended the throne. That period became notorious as the Great Troubles. It was a mess. The political structure was collapsing, and the military was struggling to keep order. In far-off regions, like the Rus' principalities, the chaos was even worse. They were practically abandoned by the central government. Now, this is where Mamai enters the scene. Mamai emerged as a formidable leader. He wasn't just any local commander. He held the title of Beklarbegi, essentially the military governor of Crimea and the northern Black Sea region. While the central power of the Horde was collapsing, Mamai was cleverly consolidating his own influence. By the time the 1370s rolled around, he had expanded his control over a vast area, stretching from Crimea all the way to the Volga River, an incredibly strategic and valuable region. This area was critical for the trade routes connecting Europe, the Middle East, and Central Asia, through which goods like silk, spices, and slaves flowed. Mamai used this economic power to strengthen his position. Despite his growing power, Mamai had a problem. He couldn't claim the title of Khan. He didn't have the right bloodline. He wasn't a descendant of Genghis Khan. And in the world, that was a big deal. You couldn't just claim the throne without Genghis Khan's blood running through your veins. So, he played it smart and put an eight-year-old boy named Muhammad Bolak on the throne. This kid had the right bloodline, being from the Mongol aristocracy, and that made him a legitimate Khan. But of course, at eight years old, Muhammad wasn't ruling anything. Mamai used the boy as a puppet Khan, keeping the facade of legitimacy while he held all the real power behind the scenes. After solidifying the power in Crimea and the western parts of the Golden Horde, his eyes turned toward the Russian principalities in the northeast. It's important to note that these regions had been paying tribute to the Golden Horde ever since the Mongol invasion in the 13th century, a sign of their submission to the Khans. But things were changing. With unrest within the Khanate, the Russian principalities, especially Moscow, began seeking to assert more autonomy and reduce their dependence on the Khanate. Mamai knew that in order to control the entire Golden Horde, he needed to keep the Russian principalities under his influence and ensure they continued to pay tribute, because tribute payments from Russia were an extremely important source of financial revenue for his military activities. So, back in 1371, Mamai decided to play a dangerous game to strengthen his grip over the Russian lands. He granted the title of Grand Duke of Vladimir to Prince Mikhail II of Tver. Now, you might be wondering, why did he choose Mikhail of all people? Well, during this period, Mikhail was a strong rival to Prince Dmitry Donskoy of Moscow, another rising power in Russia, with the support of the Grand Duchy of Lithuania, which was also expanding its territory and directly competing with Moscow for dominance over regions like Tver. From 1368 onwards, Moscow continuously fought against Tver and Lithuania, and Novgorod also became involved in the conflict. This was understandable, because Dmitry Donskoy had previously taken the ruling title of the Grand Duchy of Vladimir, which rightfully belonged to Prince Dmitry Konstantinovich of Nizhny Novgorod, a title he had been given multiple times before. Konstantinovich feared that Moscow's rapid expansion was threatening the independence of Novgorod. So, by giving Mikhail this title, Mamai was hoping to stir up division among the Russian principality and weaken Moscow's growing influence. He also believed that Mikhail could bring in more tribute, which was of course crucial for Mamai's plans. But honestly, this turned out to be a huge mistake. You see, Dmitry of Moscow wasn't the kind of guy to just sit back and accept it. To him, the title of Grand Duke of Vladimir symbolized the highest authority among the Russian principalities. He saw Mamai's move as an outright challenge to Moscow's power, and there was no way he was going to let that slide. What followed was a military showdown between Moscow and Tver. And let me tell you, Moscow didn't hold back. Dmitry's army was strong, well-organized, and funded by the wealth they'd been collecting through tribute from other principalities. Tver, on the other hand, didn't stand much of a chance. Mikhail had hoped for Mongol support, but none came. So, in the end, Moscow crushed Tver, forcing Mikhail not only to renounce his claim to the Grand Duke title, but also to recognize Moscow as the dominant power in the region, simultaneously agreeing to help Moscow in case of war against the Mongols. This was a unique development in the history of the principalities, because it was the first time since the Mongol conquest that Rus princes were deciding matters on their own, in defiance of the will of the Khans in Sarai, Golden Horde's capital city. It's also a sign that Moscow was now strong enough to stand on its own against both internal rivals and the Mongols. So, Prince Dmitry decided to go all-in. In 1374, he made a bold, risky decision. He straight-up refused to pay tribute to Mamay. The situation was further aggravated when Moscow assassinated Mamay's ambassadors in Nizhny Novgorod while they were on a mission to collect tribute, as directed by the Khan. Now, you and I both know that challenging a Mongol ruler like that was playing with fire, but Dmitry wasn't acting on a whim. He could see that Mamay was in trouble with power struggles left and right, and Mamay's finances were hurting. Dmitry probably figured that Mamay wasn't strong enough anymore to make Moscow keep paying. That's the moment Dmitry started seeing a chance. A chance to totally break free from Mongol rule and finally assert their independence. And Moscow was leading the way. Now, Mamay wasn't about to just let this slide. By 1375, he was feeling the pressure. Constant battles to hold on to power were bleeding him dry. You know how wars go. They're insanely expensive, and Mamay needed cash. So, he sent an ambassador to Moscow, along with a thousand soldiers, to persuade Dmitry to cough up the tribute he owed. But Dmitry? Not only did he refuse to pay, he even kept all tribute collected from other Russia principalities for himself and Moscow instead of giving it to Horde. And let's be real, he wasn't doing it for fun. He was gearing up, strengthening Moscow's military and financial power, preparing for the inevitable showdown with Mamay. This wasn't just a slap in the face from Mamay. It was a direct challenge to his authority, and it made him look weak in front of other lords who were already eyeing rebellion. In 1378, as a warning and to retaliate, Mamay sent troops, led by his commander Murza Begich, to strike at Moscow. The Horde had previously launched a punitive expedition against Nizhny Novgorod and defeated them, perhaps in retaliation for envoys being killed in this region. Prince Dmitry Konstantinovich was forced to take refuge in Gorodets and plead for peace. But to no avail. After receiving reinforcements, the Mongols crossed the Volga and invaded the borders of the Ryazan Principality. Cities such as Pronsk and Ryazan were burned to the ground, and the land was covered in blood. The scene of destruction recalls the period of Batu Khan's previous invasion. It seemed that history was about to repeat itself, with Russia once again in danger of being crushed under the boot of the Golden Horde. Moscow's army played a key role during this period. Dmitry Ivanovich managed to organize a serious and effective army, composed of several Russian principalities, including Serpukhov-Borovsk, Rostov, Yaroslavl, Suzdal, Bryansk, Kashinsky, Smolensk, Obolensky, Molozhsky, Tarusa, Novosilsky, Gordetsky, and Starodubovsky. The 14th century Russian army was a feudal one, where the territorial principle was the basis of organization. This meant that in times of military need, the Grand Duke, Lord, would summon all his vassals under his banner, organized by their respective principalities, cities, and inherited lands. By 1375, a total of 22 separate detachments had been merged into regiments, with a unified structure and leadership. These units were commanded by feudal lords, including boyars and princes. Military service became mandatory, leading to stricter discipline and better organization. The smallest military unit was called a spear, which was led by a notable warrior, and consisted of around ten warriors. Several spear were grouped together to form a banner, a larger unit commanded by boyars or smaller princes. A banner typically ranged in size from 500 to 1,500 soldiers, and had its own distinctive flag, making it easy to identify in the chaos of battle. These banners could operate independently or be part of larger groups. For example, groups of three to nine banners would form a regiment which was led by princes or military commanders, called voivodes. The Russian army had several types of regiments, similar to the Mongol Tumans, including the big regiment, and regiments known as the left and right hands, which were traditional divisions of the Russian army. These units also included specialized front and guard regiments for different roles during battle. In the 14th century, Russia saw a unique revival of infantry tactics. Dense formations of infantry, armed with spears and supported by archers and crossbowmen in the rear ranks, became a formidable force capable of halting enemy cavalry. This allowed the Russian cavalry time to regroup and prepare for a counter-attack. The front lines were occupied by heavily armed warriors, equipped with long spears with leaf-shaped tips, swords, daggers, shields, scale armor, and quality helmets. Behind them, medium-armed warriors took position, armed with swords, combat knives, axes, hammers, and shields for protection. Ranged weapons played a growing role in warfare, with crossbowmen and archers becoming increasingly important in Russian armies. Crossbowmen were equipped with simple crossbows that featured a footrest and a hook to help draw the bowstring. They carried a cleaving knife, an axe, and a long fighting dagger, with their arrows stored in a leather quiver hanging from their waist. The soldiers' protection was provided by conical, rounded helmets, scale armor often decorated with trims and braids, and a short coat with sleeves that reached their elbows. They also wore knee guards for added defense. A key feature of the crossbowmen's equipment was a large vertical shield, which not only protected them fully, but also served as a stable base for shooting their crossbows. This shield allowed them to remain hidden while still firing at the enemy. Together, these tactics and the use of ranged weapons helped the Russian army weaken their enemies from a distance, providing an advantage before close combat began. If the Russians relied on dense defensive formations and long-range attacks with crossbows, the Mongol army conquered with mobility of its cavalry and the superior power of its mounted archers, making them unlike any opponent the Russians had ever faced. These guys didn't just pick up a bow one day. No. From a young age, both boys and girls were thrown into competitions. Horse racing, wrestling, archery. By the time they grew up, they were masters of all sorts of weapons. Battle axes, spears, lances, daggers, even short swords. Speed was the hallmark of Mongol armies. They could move faster and farther than almost any other force of their time, often covering up to 75 miles a day, a feat that left their enemies scrambling. The backbone of this mobility was their small yet incredibly resilient horses. Mongol horses were bred for endurance and could thrive in harsh conditions with minimal sustenance. Each warrior brought 10 to 16 spare horses, zrenya, rotating between them to keep the animals fresh. In desperate times, they even drank the blood of their horses, showcasing their extraordinary adaptability and resourcefulness. The composite bow was the Mongol warrior's most iconic weapon. Unlike typical bows, these were masterfully constructed from layers of wood, horn, and sinew, giving them incredible strength and flexibility. Mongol bows had a range of up to 350 yards. Far surpassing most contemporary weapons, and their archers could fire with devastating accuracy while galloping at full speed. They even mastered the art of shooting backward during a retreat, turning what seemed like a retreat into a deadly trap. Mongol arrows were equally sophisticated. The shafts were made of wood or reed, while the tips were crafted from bone or metal, designed for various purposes. Some arrows pierced armor, others carried signals or emitted whistling sounds to confuse enemies. Each warrior carried an arsenal of around 60 arrows, ensuring they were never short of ammunition. Mongol warriors were equipped for both survival and battle. In addition to their bows, they carried lassos, battle axes, tools for repairing arrows, food supplies, and leather bottles for water or fermented drinks. Their lightweight yurts, one for every 10 riders, provided shelter on the move, ensuring that their armies could camp almost anywhere without slowing down. Armor was a critical consideration for the Mongols, but they prioritized mobility over heavy protection. Most warriors wore thick felt or leather armor, often reinforced with iron or bone plates. This combination provided sufficient defense while allowing them to move quickly and fight with agility. Helmets were made of iron or hardened leather, sometimes featuring neck guards or decorative plumes. Even their horses wore padded armor, giving both rider and steed an added layer of protection without sacrificing speed. For several days, the two armies stood facing each other on opposite banks. The horde began to cross the river. The Moscow prince, luring the enemy into a pre-prepared trap, began to withdraw his troops from the river. On August 11, 1378, the horde forces including 10,000 warriors, led by the commander Bagich, crossed the Voza River and engaged the Muscovite army. Initially, Bagich had a straightforward strategy. He relied on the sheer power and aggression of his heavy cavalry to break Moscow's defensive lines. With the horde's numerical superiority, Bagich believed his swift and overwhelming assault would cause Moscow's forces to collapse in panic. The battlefield, positioned near the river, seemed to play to the strengths of his cavalry. Bagich planned to use their mobility to encircle Moscow's troops or drive them toward the riverbank, leaving them no room to regroup. The strategy focused on a quick, crushing attack to shatter Moscow's formations, exploit weak points, and ultimately annihilate their main forces. However, this plan unraveled due to unforeseen challenges. Moscow's forces, led by Grand Prince Dmitry Donskoy, had meticulously prepared for the confrontation. Dmitry's scouts were instrumental in the lead-up to the battle. Their intelligence-gathering efforts provided vital information, including Bagich's intention to use the ford to cross the river. Armed with this knowledge, Dmitry positioned his troops strategically, turning the terrain to his advantage. At the heart of the battlefield, within a dense forest, Moscow's forces had defensive measures. Trenches and ramparts were built, and infantry and crossbowmen were stationed there, ready to repel the horde's cavalry. On either flank, heavily armed units were placed. One wing was commanded by Daniel Pronsky, while the other was under Timofey Velyaminov. Dmitry himself led the central regiment, positioned to respond to the main assault. As the Tatar horde began crossing the Voza River, Dmitry Donskoy put his meticulously-crafted plan into action. He had prepared his troops not just to hold their ground, but to turn the horde's aggression against them. The first step was an active defense. In the center of the Moscow formation stood archers and crossbowmen, who unleashed a relentless barrage of fire upon the advancing horde cavalry. The horde, renowned for their swift and devastating charges, found themselves slowed by the terrain. Dense forests flanked the battlefield, and the riverbanks and marshes further restricted their movements. Their prized cavalry, typically unstoppable on open ground, struggled to maneuver in these conditions. While the horde's frontal assault faltered, Dmitry bided his time. The Moscow troops stood firm, their discipline and positioning holding back the enemy's advance. Then, at the decisive moment, Dmitry led the main regiment in a counterattack. The troops surged forward with precision, striking at the horde with a calculated ferocity that caught them off guard. But Dmitry's strategy did not stop there. Seeing the enemy already disorganized, he signaled his wing regiments to move. These regiments, positioned strategically on either side, launched devastating flank attacks. The horde, accustomed to being the hunters, found themselves surrounded. The center and flanks of their forces were now under attack, splitting their ranks and creating chaos. For the horde, the situation quickly spiraled out of control. The dense forest and marshes, combined with the unrelenting attacks from Moscow's troops, left them unable to regroup. Panic spread like wildfire through their ranks. Soldiers who had once been fierce warriors now fought to escape, abandoning any semblance of order. The river, which had been their crossing point, now became their greatest obstacle. Many tried to retreat, only to be driven into the water. Laden with heavy armor and weapons, they stood little chance. Some drowned in the river's depths, while others were struck down by pursuing Moscow soldiers. To make matters worse, as the fleeing horde forces reached the opposite riverbank, they encountered an unexpected obstacle – the Russian supply train. This wasn't just a convoy carrying provisions. It was part of Dmitriy's broader strategy. Positioned on the far side of the river, the train served as both a rearguard and a barrier, ensuring the horde couldn't escape easily. The train's escorts, which included heavily armed infantry, wasted no time. They attacked the disorganized horde soldiers who had managed to cross the river, cutting down anyone who posed a threat. For those still trying to escape through the marshes, the situation was even more dire. Many got stuck in the mud, unable to move, becoming easy targets for Moscow's relentless soldiers. It was a complete rout. Among the dead were Begich, their leader, along with several high-ranking commanders, known as Mirzas, and Temniki, cavalry corps commanders, including Kazibei, Koverga, Karuluk, and Kastrok. The scale of the loss was extraordinary. Typically, horde commanders stayed away from the battlefield, directing their troops from a safe distance. But this time, nearly all of their leadership was wiped out in a single battle, a clear sign of just how devastating their defeat was. As night fell, the darkness brought an end to the pursuit. Moscow's troops regrouped, unable to chase the remaining enemy forces further in the pitch-black conditions. However, Dmitriy was not ready to let the survivors escape without consequence. At dawn, he ordered his forces to cross the river and resume the chase. Unfortunately, the remnants of the horde had already retreated too far. Their swift flight made further pursuit impractical. Although the fleeing horde troops evaded capture, they left behind a treasure trove of supplies. Moscow's soldiers found abandoned tents, carts, and provisions, filled with goods that the horde had no time to carry. It was a rich reward for their efforts, and a clear sign of just how desperate the enemy had been to escape. The Moscow forces also took time to honor their fallen comrades. Burial mounds were erected on the battlefield, marking the site where Moscow's warriors had stood their ground and turned the tide against the Golden Horde. After the battle, Mamay's army was almost completely destroyed, and he had to replenish mercenaries for the Battle of Kulikovo in 1380. Moscow's losses were considerably lighter, estimated to be in the hundreds rather than the thousands. The exact number remains unclear. The Battle of Vozha is considered one of the first major victories of the Russian principalities against the Golden Horde. Before that, the Russian principalities had often suffered defeats or had to accept submission and pay tribute. This was considered an important test, helping Moscow better understand the tactics and weaknesses of the Tatar cavalry and prepare for larger battles. Thanks to that, two years after the Battle of Vozha, Dmitry Donskoy continued to lead the Russian army to a resounding victory at the Battle of Kulikovo, one of the most famous battles in Russian history.
