Battle of Maritsa

The Battle of Maritsa, or Battle of Chernomen (Маричка битка, бој код Черномена, Битката при Марица, битката при Черномен, Çirmen Muharebesi, İkinci Meriç Muharebesi in tr. Second Battle of Maritsa) took place at the Maritsa River near the village of Chernomen (today Ormenio in Greece) on September 26, 1371 between the forces of Ottoman commanders Lala Şâhin Paşa and Gazi Evrenos and Serbian commanders King Vukašin Mrnjavčević and his brother Despot Jovan Uglješa   who also wanted to get revenge of First Battle of Maritsa.

Battle
The Serbian army numbered 20,000 -70,000    men. Despot Uglješa wanted to make a surprise attack on the Ottomans in their capital city, Edirne, while Murad I was in Asia Minor. The Ottoman army was much smaller Byzantine Greek scholar Laonikos Chalkokondyles and other sources give the number of 800 men, but due to superior tactics, by conducting a night raid on the Serbian camp, Şâhin Paşa was able to defeat the Serbian army and kill King Vukašin and despot Uglješa. Thousands of Serbs were killed, and thousands drowned in the Maritsa river when they tried to regroup for counter-attack. Heavy armor became a disadvantage in the river water. After the battle, the Maritsa ran scarlet with blood.

Aftermath
Macedonia and parts of Greece fell under Ottoman power after this battle. The battle was a part of the Ottoman campaign to conquer the Balkans and was preceded by the Ottoman capturing of Sozopol and succeeded by the capture of the cities of Drama, Kavála and Serrai in modern Greece. The battle preceded the later 1389 Battle of Kosovo, and was one of many in history of the Serbian-Turkish wars.
