The secondBattle of Dorylaeum took place nearDorylaeum in October 1147 during theSecond Crusade. The battle consisted of a series of encounters over several days. The German Crusader forces ofConrad III were defeated by theSeljuk Turks led by SultanMesud I.

Following escalating friction between theByzantine Empire and the German Crusader army, including armed clashes, the Germans were ferried from the environs ofConstantinople to the Asiatic shores of theBosporus. With inadequate supplies, the Crusaders moved to the interior ofAnatolia, intending to take an overland route to theHoly Land.[4]
As the Crusaders crossed into the Anatolian plateau they entered an area of debatable frontier districts between the Byzantines andSeljuk Turks. Once beyond effective Byzantine control, the German army came under harassing attacks from the Turks, who excelled at such tactics. The poorer and less well-supplied infantry of the Crusader army were the most vulnerable to hit-and-runhorse archer attack and began to take casualties and lose men to capture. The area through which the Crusaders were marching was largely barren and arid; therefore the army could not augment its supplies and was troubled by thirst.
When the Germans were about three days march beyondDorylaeum, the nobility requested that the army turn back and regroup. As the Crusaders began their retreat, on 25 October the Turkish attacks intensified, and order broke down, the retreat then became a rout with heavy casualties. Conrad was wounded by arrows during the rout. The Crusaders lost virtually all of their baggage and, according to the Syriac Chronicle, "The Turks grew rich for they had taken gold and silver like pebbles with no end."[4][5]
On regaining lands under firm Byzantine control Turkish attacks ceased. The failure of the Crusaders was partly blamed on Byzantine treachery by the contemporary chroniclerWilliam of Tyre; the Greek guides and local population were accused of being in league with the Seljuks. However, convincing evidence or motivation for this scenario is lacking, though the Byzantine EmperorManuel I had hurriedly arranged a peace treaty with the Seljuk sultan. German losses are difficult to estimate, William of Tyre stating that only a remnant of the army was left. Of the 113 named men in the army, 22 are recorded to have died on the crusade, 42 survived and 49 were unaccounted for.[4] However, the named men would have been of the knightly and noble class, who being better armoured and provisioned than the infantry were more likely to survive. The detailed fate of a significant proportion of the German army shows that the notion of it being completely destroyed near Dorylaeum is untenable. Nicolle states that the 'professional core' of Conrad's army, i.e. the knights and other cavalry, remained largely intact, though with shaken morale.[6]
The Germans subsequently joined forces with the French Crusaders, led byLouis VII of France, atNicaea before proceeding along the coastal route around western Anatolia. The joint forces came under renewed Seljuk attack, and Conrad and the elite of his force took ship atEphesus. Conrad returned by sea to Constantinople, where he was reconciled with the Byzantine emperor. The remainder of the German crusaders, in company with the French, moved on toAttalia, where some were shipped toAntioch. Of those who attempted the overland route to Antioch there is no accurate record of the number of survivors. Manuel later provided ships to take Conrad and his entourage toPalestine. The Second Crusade eventually failed in itsattempt to take the city ofDamascus.[7][8]
The anonymous German author ofAnnales Herbipolenses, a native ofWürzburg, speaks of meeting many returned soldiers, presumably of the wealthier section of the army. They had been captured by the Turks, and had been ransomed by, or through the mediation of, theArmenians of Cilicia.[9]39°47′N30°31′E / 39.783°N 30.517°E /39.783; 30.517
