Battle of IconiumKonya, Turkey
After reaching Anatolia, Frederick was promised safe passage through the region by the Turkish Sultanate of Rum, but was faced instead with constant Turkish hit-and-run attacks on his army. A Turkish army of 10,000 men was defeated at the Battle of Philomelion by 2,000 Crusaders, with 4,174–5,000 Turks slain. After continued Turkish raids against the Crusader army, Frederick decided to replenish his stock of animals and foodstuffs by conquering the Turkish capital of Iconium. On 18 May 1190, the German army defeated its Turkish enemies at the Battle of Iconium, sacking the city and killing 3,000 Turkish troops.
