Battle of Grobnik field

The Battle of Grobnik field is a battle that occurred in 1242 between the Croats and the Tatars. The battle was a focus of an early romantic poem Grobnik field (near Rijeka) written in 1842 by Dimitrija Demeter for the 600th anniversary of the battle. Legend has it that, in a last-ditch struggle, Croats from all over the region gathered there and killed thousands of Mongols, who withdrew, never to return.

Historical background
The Mongols began attacking Europe in the 1220s. They conquered most of Russia and then headed west in the late 1230s. In almost every battle the Christian armies were destroyed and much of Hungary, Poland, Austria and the Balkans were laid waste by Batu Khan, grandson of Genghis Khan. It is known that the Mongols overran Zagreb and swept through Lika and Dalmatia but were unable to take Vinodol. The extent of death and destruction dealt out by the Mongols was compared to an epidemic of the black plague.

Battle
Arriving at the Grobnik field, Tatars encountered a native Croatian army that tried to stop their advantage and invasion. In the battle that followed, Tatars were destroyed, losing an entire army of 30,000 people led by the notorious army leader Batu Khan. They were beaten by units from all the corners of Croatia, and so natives ensured peace. It was one of the last battles of the Mongols in Europe, after which they retreated to their homeland in far Asia. There seems to be no certain evidence of the battle uncovered on the battlefield.

It is believed that Grobnik (English: field of graves) got its name from the many graves that were used after the battle due to great casualties.

Controversy and history
Some scholars and historians have long doubted and still are arguing if the battle ever took place. Most of them acknowledge that battle didn't occur. There has been no physical evidence of a battle uncovered on the supposed battlefield, nor is the battle mentioned in any document from that time. The first accounts about this battle are mentioned in the documents from the 14th century, but some claim that they were either a hoax or not verifiable. Legend also has it that the Croats also fought off a Turkish invasion at Grobnik field several centuries later by wearing the heads of cows and other animals (see zvončari), scaring the enemy.
