The Mongol Conquests 1206 - 1368
The Mongol invasion of Europe in the 13th century was the conquest of Europe by the Mongol Empire, by way of the destruction of East Slavic principalities, such as Kiev and Vladimir. The Mongol invasions also occurred in Central Europe, which led to warfare among fragmented Poland, such as the Battle of Legnica (9 April 1241) and in the Battle of Mohi (11 April 1241) in the Kingdom of Hungary.
The operations were planned by General Subutai (1175–1248) and commanded by Batu Khan (c. 1207–1255) and Kadan. Both men were grandsons of Genghis Khan; their conquests integrated much European territory to the empire of the Golden Horde. Warring European princes realized they had to cooperate in the face of a Mongol invasion, so local wars and conflicts were suspended in parts of central Europe, only to be resumed after the Mongols had withdrawn
Invasions and conquest of Rus' lands
Ögedei Khan ordered Batu Khan to conquer Rus' in 1235. The main force, headed by Jochi's sons, and their cousins, Möngke Khan and Güyük Khan, arrived at Ryazan in December 1237. Ryazan refused to surrender, and the Mongols sacked it and then stormed Suzdalia. Many Rus' armies were defeated; Grand Prince Yuri was killed on the Sit River (March 4, 1238). Major cities such as Vladimir, Torzhok, and Kozelsk were captured.
Afterward, the Mongols turned their attention to the steppe, crushing the Kypchaks and the Alans and sacking Crimea. Batu appeared in Ukraine in 1239, sacking Pereiaslav and Chernihiv. Most of the Rus' princes fled when it became clear resistance was futile.
The Mongols sacked Kiev on December 6, 1240, and conquered Galich and Volodymyr-Volynskyi. Batu sent a small detachment to probe the Poles before passing on to Central Europe. One column was routed by the Poles while the other defeated the Polish army and returned
Invasion of Central Europe
The attack on Europe was planned and executed by Subutai, who achieved perhaps his most lasting fame with his victories there. Having devastated the various Rus' principalities, he sent spies into Poland and Hungary, and as far as eastern Austria, in preparation for an attack into the heartland of Europe.
Having a clear picture of the European kingdoms, he prepared an attack nominally commanded by Batu Khan and two other familial-related princes. Batu Khan, son of Jochi, was the overall leader, but Subutai was the strategist and commander in the field, and as such, was present in both the northern and southern campaigns against Rus' principalities.
He also commanded the central column that moved against Hungary. While Kadan's northern force won the Battle of Legnica and Güyük's army triumphed in Transylvania, Subutai was waiting for them on the Hungarian plain.
The newly reunited army then withdrew to the Sajo River where they inflicted a decisive defeat on King Béla IV of Hungary at the Battle of Mohi. Again, Subutai masterminded the operation, and it would prove one of his greatest victories.
Invasion of fragmented Poland
The Mongols invaded Central Europe with three armies. One army defeated an alliance which included forces from fragmented Poland and their allies, led by Henry II the Pious, Duke of Silesia in the Battle of Legnica. A second army crossed the Carpathian mountains and a third followed the Danube. The armies re-grouped and crushed Hungary in 1241, defeating the Hungarian army at the Battle of Mohi on April 11, 1241.
The devastating Mongol invasion killed half of Hungary's population. The armies swept the plains of Hungary over the summer, and in the spring of 1242, regained impetus and extended their control into Dalmatia and Moravia. The Great Khan had, however, died in December 1241, and on hearing the news, all the "Princes of the Blood," against Subotai's recommendation, went back to Mongolia to elect the new Khan.
After sacking Kiev, Batu Khan sent a smaller group of troops to Poland, destroying Lublin and defeating an inferior Polish army. Other elements—not part of the main Mongol force—saw difficulty near the Polish-Galich border.
The Mongols then reached Polaniec on the Czarna Hańcza, where they set up camp. There, the Voivode attacked them with the remaining Cracovian knights, which were few in number, but determined to vanquish the invader or die. Surprise gave the Poles an initial advantage and they managed to kill many Mongol soldiers.
When the invaders realized the actual numerical weakness of the Poles, they regrouped, broke through the Polish ranks and defeated them. During the fighting, many Polish prisoners of war found ways to escape and hide in the nearby woods. The Polish defeat was partly influenced by the initially successful Polish knights having been distracted by looting
Invasion of Czech lands
After the defeat of the European forces at Legnica, the Mongols then continued pillaging throughout Poland's neighboring kingdoms, particularly Silesia and Moravia. King Wenceslaus I of Bohemia fled back to protect his kingdom after arriving late and discovering the devastation the Mongols caused in those places; gathering reinforcements from Thuringia and Saxony as he retreated.
He stationed his troops in the mountainous regions of Bohemia where the Mongols wouldn't be able to utilize their cavalry effectively.
By that time, the Mongolian forces had divided into two, one led by Batu and Subutai who were planning to invade Hungary, and another led by Baidar and Kadan who were ravaging their way through Silesia and Moravia. When they arrived to attack Bohemia, the kingdom's defenses discouraged them from attacking and they withdrew to the town of Othmachau.
A small force of Mongolians did attack Kłodzko but the Bohemian cavalry under Wenceslaus managed to fend them off. The Mongols then tried to take the town of Olomouc, but Wenceslaus managed to get the aid of the Duke of Austria and they repulsed the raid.
A Mongol commander was captured in a sortie near Olomouc. Under Wenceslaus' leadership during the Mongol invasion, Bohemia remained one of a few European kingdoms that were never conquered and molested by the Mongols even though most kingdoms around it such as Poland and Moravia were ravaged.
Such was his success that chroniclers sent messages to Emperor Frederick II of his "victorious defense". After these failed attempts, Baidar and Kadan continued raiding Moravia before finally going southward to reunite with Batu and Subutai in Hungary
Invasion of the Kingdom of Hungary
The Hungarians had first learned about the Mongol threat in 1229 when King Andrew II granted asylum to some fleeing Russian boyars. Some Magyars (Hungarians), left behind during the main migration to the Pannonian basin, still lived on the banks of the upper Volga. In 1237 a Dominican friar, Julianus, set off on an expedition to lead them back and was sent back to King Béla with a letter from Batu Khan. In this letter,
Batu called upon the Hungarian king to surrender his kingdom unconditionally to the Tatar forces or face complete destruction. Béla did not reply, and two more messages were later delivered to Hungary. The first, in 1239, was sent by the defeated Cuman tribes, who asked for and received asylum in Hungary. The second was sent in February 1241 by the defeated Polish princes.
Only then did King Béla call upon his magnates to join his army in defense of the country. He also asked the papacy and the Western European rulers for help. Foreign help came in the form of a small knight-detachment under the leadership of Frederick II, Duke of Austria, but it was too small to change the outcome of the campaign. The majority of the Hungarian magnates also did not realize the urgency of the matter.
Some may have hoped that a defeat of the royal army would force Béla to discontinue his centralization efforts and thus strengthen their own power.
Although the Mongol danger was real and imminent, Hungary was not prepared to deal with it; in the minds of a people who had lived free from nomadic invasions for the last few hundred years, an invasion seemed impossible.
And Hungary was no longer a predominantly soldier population. Only rich nobles were trained as heavy-armored cavalry. The Hungarians had long since forgotten the light-cavalry strategy and tactics of their ancestors, which were similar to those now used by the Mongols. The Hungarian army (some 60,000 on the eve of the Battle of Mohi) was made up of individual knights with tactical knowledge, discipline, and talented commanders.
Because his army was not experienced in nomadic warfare, King Béla welcomed the Cuman King Kuthen (also known as Kotony) and his fighters. However, the Cuman invitation proved detrimental to the Hungarians because Batu Khan considered this acceptance of a group he considered rebels as justifications for his invasion of Hungary. After rumors began to circulate in Hungary that the Cumans were agents of the Mongols, some hot-headed Hungarians attacked the Cuman camp and killed Kotony.
This led the enraged Cumans to ride south, looting, ravaging the countryside, and slaughtering the unsuspecting Magyar population. The Austrian troops retreated to Austria shortly thereafter to gain more western aid. The Hungarians now stood alone in the defense of their country.
The 1241 Mongol invasion first affected Moldavia and Wallachia. Tens of thousands of Wallachians and Moldavians lost their lives defending their territories from the Golden Horde. Crops and goods plundered from Wallachian settlements seem to have been a primary supply source for the Golden Hordes
The invaders killed up to half of the population and burned down most of their settlements, thus destroying much of the cultural and economic records from that period. Neither Wallachians nor the army of Hungary offered much resistance against the Mongols. The swiftness of the invasion took many by surprise and forced them to retreat and hide in forests and the enclosed valleys of the Carpathians.
The Hungarian army arrived and encamped at the Sajó River on April 10, 1241, without having been directly challenged by the Mongols. The Mongols, having largely concealed their positions, began their attack the next night; after heavier-than-expected losses inflicted by Hungarian crossbowmen, the Mongols adjusted their strategy and routed the Hungarian forces rapidly.
A major Hungarian loss was imminent, and the Mongols intentionally left a gap in their formation to permit the wavering Hungarian forces to flee and spread out in doing so, leaving them unable to effectively resist the Mongols as they picked off the retreating Hungarian remnants. While the king escaped with the help of his bodyguard, the remaining Hungarian army was mercilessly killed by the Mongols or drowned in the river as they attempted escape.
Following their decisive victory, the Mongols now systematically occupied the Great Hungarian Plains, the slopes of the northern Carpathian Mountains, and Transylvania. Where they found local resistance, they ruthlessly killed the population. Where the locale offered no resistance, they forced the men into servitude in the Mongol army.
Still, tens of thousands avoided Mongol domination by taking refuge behind the walls of the few existing fortresses or by hiding in the forests or large marshes along the rivers. The Mongols, instead of leaving the defenseless and helpless people and continuing their campaign through Pannonia to Western Europe, spent the entire summer and fall securing and pacifying the occupied territories.
On Christmas day 1241, the costly siege of Esztergom destroyed the capital and economic center of the Kingdom of Hungary, forcing the capital to be moved to Budapest.
During the winter, contrary to the traditional strategy of nomadic armies which started campaigns only in spring-time, they crossed the Danube and continued their systematic occupation, including Pannonia. They eventually reached the Austrian borders and the Adriatic shores in Dalmatia. The Mongols appointed a darughachi in Hungary and minted coins in the name of Khagan.
According to Michael Prawdin, the country of Béla was assigned to Orda by Batu as an appanage. At least 20%-40% of the population died, by slaughter or epidemic. Rogerius of Apulia, an Italian monk, and chronicler who witnessed and survived the invasion pointed out not only the genocidal element of the occupation but also that the Mongols especially "found pleasure" in humiliating local women.
But while the Mongols claimed control of Hungary, they could not occupy fortified cities such as Fehérvár, Veszprém, Tihany, Győr, Pannonhalma, Monson, Sopron, Vasvár, Újhely, Zala, Léka, Pozsony, Nyitra, Komárom, Fülek and Abaújvár. Learning from this lesson, fortresses came to play a significant role in Hungary. King Béla IV rebuilt the country and invested in fortifications.
Facing a shortage of money, he welcomed the settlement of Jewish families, investors, and tradesmen, granting them citizenship rights. The King also welcomed tens of thousands of Kun (Cumans) who had fled the country before the invasion. Chinese fire arrows were deployed by Mongols against the city of Buda on December 25, 1241, which they overran.
The Mongolian invasion taught the Magyars a simple lesson: although the Mongols had destroyed the countryside, the forts, and fortified cities had survived. To improve their defense capabilities for the future, they had to build forts, not only on the borders but also inside the country. In the siege of Esztergom, the Spanish defenses manage to hold off the Mongolians despite having overwhelming numerical superiority and 30 siege machines which they had just used to reduce the wooden towers of the city.
During the remaining decades of the 13th century and throughout the 14th century, the kings donated more and more royal land to the magnates with the condition that they build forts and ensure their defenses.
Invasion of the Kingdom of Croatia
When routed on the banks of the Sajo River in 1241 by the Mongols, Béla IV fled to today's Zagreb in Croatia. Batu sent a few times (roughly 20,000 men at arms) under Khadan in pursuit of Bela. The major objective was not the conquest but the capture of the Arpad king.
The poorly fortified Zagreb was unable to resist the invasion and was destroyed, its cathedral burned by Mongols. In preparation for a second invasion, Gradec was granted a royal charter or Golden Bull of 1242 by King Béla IV, after which citizens of Zagreb engaged in building defensive walls and towers around their settlement.
The Mongols' pursuit of Béla IV continued from Zagreb through Pannonia to Dalmatia. While in pursuit, the Mongols under the leadership of Kadan (Qadan) suffered a major defeat at Klis Fortress in Croatia in March 1242. The Mongols pursued Béla IV from town to town in Dalmatia, while Croatian nobility and Dalmatian towns such as Trogir and Rab helped Béla IV to escape.
After their defeat against the Croatian soldiers, the Mongols retreated and Béla IV was awarded Croatian towns and nobility. Only the city of Split did not aid Béla IV in his escape from the Mongols.
Some historians claim that the mountainous terrain of Croatian Dalmatia was fatal for the Mongols because of the great losses they suffered from Croat ambushes set up in mountain passes. In any case, though much of Croatia was plundered and destroyed, long-term occupation was unsuccessful.
Invasion of Austria
The subjugation of Hungary opened a pathway for the Mongol Horde to invade Vienna. Using similar tactics during their campaigns in previous Eastern and Central European countries, the Mongols first launched small squadrons to attack isolated settlements in the outskirts of Vienna in an attempt to instill fear and panic among the populace.
In 1241 the Mongols raided Wiener Neustadt and its neighboring districts, located south of Vienna. Wiener Neustadt took the brunt of the attack and like previous invasions, the Mongols committed horrible atrocities on the relatively unarmed populace.
The Duke of Austria, Frederick II, had previously engaged the Mongols in Olomouc and in the initial stages of the Battle of Mohi. Unlike in Hungary however, Vienna under the leadership of Duke Frederick and his knights, together with their foreign allies, managed to rally quicker and annihilate the small Mongolian squadron.
After the battle, the Duke estimated that the Mongols lost over 300 to 700 men while the Europeans only lost 100. Austrian knights also subsequently defeated the Mongols at the borders of the River March in the district of Theben. After the failed initial raids, the rest of the Mongols retired back into Russia after learning of the Great Khan Ögedei's death.
Invasion of Bulgaria
During his withdrawal from Hungary back into Russia, part of Batu Khan's army invaded Bulgaria. A Mongolian force was defeated by the Bulgarian army under Tsar Ivan Asen II. A larger force returned to raid Bulgaria again the same year, though little is known of what happened. According to the Persian historian Rashid-al-Din Hamadani, the Bulgarian capital of Tarnovo was sacked.
This is unlikely, but the rumor of it spread widely, being repeated in Palestine by Bar Hebraeus. The invasion of Bulgaria is mentioned in other contemporary sources, such as Philippe Mouskès, Thomas of Cantimpré and Ricoldo of Montecroce. Contemporary documents indicate that by 1253, Kaliman I was a tribute-paying vassal of the Mongols, a status he had probably been forced to accept during the invasion of 1242.
European tactics against Mongols
The traditional European method of warfare of melee combat between knights ended in catastrophe when it was deployed against the Mongol forces as the Mongols were able to keep a distance and advance with superior numbers. The New Encyclopædia Britannica, Volume 29 says that "Employed against the Mongol invaders of Europe, knightly warfare failed even more disastrously for the Poles at the Battle of Legnica and the Hungarians at the Battle of Mohi in 1241.
Feudal Europe was saved from sharing the fate of China and Muscovy not by its tactical prowess but by the unexpected death of the Mongols' supreme ruler, Ögedei, and the subsequent eastward retreat of his armies."
However, during the initial Mongol invasion and the subsequent raids by the divided Mongol Empire afterward, heavily armored knights and cavalry proved more effective at fighting the Mongols than their light-armored counterparts.
During the Battle of Mohi for example, while the Hungarian light cavalry and infantry were decimated by Mongol forces, the heavily armored knights in their employ (such as the Knights Templar) fought significantly better (likely due to their better armor, equipment, and training).
During the Battle of Legnica, the Knights Templar that numbered between 65-88 during the battle lost only three knights and 2 sergeants. Austrian knights under Duke Frederick also fared better in fighting the Mongol invasion of Vienna.
King Béla IV hired the help of the Knights of St. John, as well as training his own better-armed local knights, in preparation for the Second Mongol invasion of Hungary. In the decades following the Mongolian raids on European settlements, Western armies (particularly Hungary) have started to adapt to the Mongol tactics by building better fortifications against siege weapons and improving their heavy cavalry.
After the division of the Mongol Empire into four fragments, when the Golden Horde attempted the next invasion of Hungary, Hungary had increased their proportion of knights (led by Ladislaus IV of Hungary) and they quickly defeated the main Golden Horde Army in the hills of western Transylvania.
By this time as well, many Eastern and Central European countries had ended their hostilities with one another and united to finally drive out the remnants of the Golden Horde. Guerrilla warfare and stiff resistance also helped many Europeans, particularly those in Croatia and Dzurdzuketia, in preventing the Mongols from setting a permanent hold and driving them off
Mongol diffusion of Chinese gunpowder to Europe
Several sources mention Chinese firearms and gunpowder weapons being deployed by the Mongols against European forces at the Battle of Mohi in various forms, including bombs hurled via catapult. Professor Kenneth Warren Chase credits the Mongols for introducing gunpowder and its associated weaponry into Europe.
A later legend arose in Europe about a mysterious Berthold Schwarz who is credited with the invention of gunpowder by 15th- through 19th-century European literature. However, it is known that William of Rubruck, a Flemish missionary who visited the Mongol court of Mongke Khan at the Karakorum and returned to Europe in 1257.
Was a friend of English philosopher Roger Bacon, who recorded the earliest known European recipe for gunpowder in his Opus Majus of 1267. This came more than two centuries after the first known Chinese description of the formula for gunpowder in 1044
End of the Mongol advance
But Asia too was marching against the West. At one moment it had seemed as if all Europe would succumb to a terrible menace looming up from the East. Heathen Mongol hordes from the heart of Asia, formidable horsemen armed with bows, had rapidly swept over Russia, Poland, Hungary, and in 1241 inflicted simultaneous crushing defeats upon the Germans near Breslau and upon European cavalry near Buda.
Germany and Austria at least lay at their mercy. Providentially in this year, the Great Khan died in Mongolia; the Mongol leaders hastened back the thousands of miles to the Karakorum, their capital, to elect his successor, and Western Europe escaped.
During the summer and autumn of 1241, most of the Mongol forces were resting on the Hungarian Plain. In late March 1242, they began to withdraw. The most common reason given for this withdrawal is the Great Khan Ögedei's death on December 11, 1241.
Ögedei Khan died at the age of fifty-six after a binge of drinking during a hunting trip, which forced most of the Mongolian army to retreat back to Mongolia so that the princes of the blood could be present for the election of a new great khan.
This is attested to by one primary source: the chronicle of Giovanni da Pian del Carpine, who after visiting the Mongol court, stated that the Mongols withdrew for this reason; he further stated that God had caused the Great Khan's death to protect Latin Christendom
By Carpini's account, a messenger would have to be able to make the journey from Mongolia to Central Europe in a little over 3 months at a minimum; according to Carpini, the messenger actually arrived in January, meaning he took about 1 month in the middle of winter.
Carpini himself accompanied a Mongol party in a much shorter journey (from Kiev to Mongolia) during the summer and fall of 1246, where the party "made great speed" in order to reach the election ceremony in time, and made use of several horses per person while riding nearly all day and night. It took five months.
Rashid Al-Din, a historian of the Mongol Ilkhanate, explicitly states in the Ilkhanate's official histories that the Mongols were not even aware of Ogedei's death when they began their withdrawal. Rashid Al-Din, writing under the auspices of the Mongol Empire, had access to the official Mongol chronicle when compiling his history. John Andrew Boyle asserts, based on the orthography, that Rashid Al-Din's account of the withdrawal from central Europe was taken verbatim from Mongolian records.
Another theory is that weather data preserved in tree rings points to a series of warm, dry summers in the region until 1242. When temperatures dropped and rainfall increased, the local climate shifted to a wetter and colder environment. That, in turn, caused flooding of the formerly dry grasslands and created a marshy terrain
Those conditions would have been less than ideal for the nomadic Mongol cavalry and their encampments, reducing their mobility and pastureland, curtailing their invasion into Europe west of the Hungarian plain, and hastening their retreat.
The true reasons for the Mongol withdrawal are not fully known, but numerous plausible explanations exist. The Mongol invasion had bogged down into a series of costly and frustrating sieges, where they gained little loot and ran into stiff resistance.
They had lost a large number of men despite their victories (see above). Finally, they were stretched thin in the European theater and were experiencing a rebellion by the Cumans in what is now southern Russia, and the Caucasus Other argue Europe's bad weather had an effect: Hungary has a high water table so it floods easily.
An analysis of tree rings there found that Hungary had a cold wet winter in early 1242, which likely turned Hungary’s central plain into a huge swamp; so, lacking pastures for their horses, the Mongols would have had to fall back to Russia in search of better grasslands.
Some historians believe that the reason for Batu's stopping at the Mohi River was that he never intended to advance further. He had made the Russian conquest safe for the years to come, and when the Great Khan died and Batu rushed back to Mongolia to put in his claim for power, it ended his westward expansion.
Subutai's recall at the same time left the Mongol armies without their spiritual head and primary strategist. Batu Khan was not able to resume his plans for conquest to the "Great Sea" (the Atlantic Ocean) until 1255 after the turmoil after Ögedei's death had finally subsided with the election of Möngke Khan as Great Khan. Though he was capable of invading Western Europe, he was no longer interested.
Against Byzantine Thrace Against Bulgaria Against Hungary (1285)Against Serbia (1291)
During the reign of Berke, there was also a raid against Thrace. In the winter of 1265, the Bulgarian czar, Constantine Tych, requested Mongol intervention against the Byzantines in the Balkans.
Nogai Khan led a Mongol raid of 20,000 cavalries (two tumens) against the territories of Byzantine eastern Thrace. In the spring of 1265, Michael VIII Palaeologus confronted the Mongols, but his smaller squadron apparently had very low morale and was quickly routed. Most of them were cut down as they fled. Michael was forced to retreat to Constantinople on a Genoese ship while Nogai's army plundered all of Thrace.
Following this defeat, the Byzantine emperor made an alliance with the Golden Horde (which was massively beneficial for the latter), giving his daughter Euphrosyne in marriage to Nogai. Michael also sent much valuable fabric to Golden Horde as a tribute.
In 1285 Nogai Khan led a raid of Hungary alongside Talabuga. Nogai leads an army that ravaged Transylvania with success: Cities like Reghin, Brașov, and Bistrița were plundered and ravaged. However, Talabuga, who led the main army in Northern Hungary, was stopped by the heavy snow of the Carpathians and the invading force was defeated near Pest by the royal army of Ladislaus IV and ambushed by the Székely in the return.
Nogai's own column suffered serious casualties at the hands of the local troops (Saxons and Vlachs) and was harried on his withdrawal by the royal army, fresh from their victory over Talabuga.
As with later invasions, it was repelled handily, the Mongols losing much of their invading force. The outcome could not have contrasted more sharply with the 1241 invasion, mostly due to the reforms of Béla IV, which included advances in military tactics and, most importantly, the widespread building of stone castles, both responses to the defeat of the Hungarian Kingdom in 1241.
The failed Mongol attack on Hungary greatly reduced the Golden Horde's military power caused them to stop disputing Hungarian borders.
In 1291 a large Mongol-Bulgarian alliance raided into Serbia, where Serbian king Stefan Uroš II Milutin defeated them. However, the Serbian king acknowledged Nogai's supremacy and sent his son as hostage to prevent further hostility when Nogai threatened to lead a punitive expedition himself.
Counter-Invasions of Europe
By the mid-14th century, the grip of the Golden Horde over Central and Eastern Europe has started to weaken. Several European kingdoms started various incursions into Mongol-controlled lands with the aim of reclaiming captured territories as well as add new ones from the Empire itself.
The Kingdom of Georgia, under the leadership of King George V the Brilliant, restored Georgian dominance in their own lands and even took the Empire of Trebizond from Mongol hands.
Lithuania, taking advantage with the internal strifes in the Golden Horde, started an invasion of their own, defeating the Mongols at the Battle at Blue Waters, as well as conquering territories of the Golden Horde such as the Principality of Kiev all the way to the Dnieper River, before being halted after their defeat at the Battle of the Vorskla River.
Russia has also started to reclaim many Rus lands. In 1345, the Kingdom of Hungary took the initiative and launched their own invasion force into Mongolian territory, capturing what would become Moldavia.
By this point, some Western European armies have also started to meet the Mongols in their conquered territories. In Caffa for example, when the Mongols under Janibeg besieged it after a large fight between Christians and Muslims began, a relief force of an Italian army came and defeated the Mongols,
Killing 15,000 of their troops and destroying their siege engines. A year later, the Italians blockaded Mongol ports in the region, forcing Janibeg to negotiate, and in 1347 the Italians were allowed to re-establish their colony in Tana
