Rather than taking the coastal road around Anatolia through Christian-held territory, by which he sent most of his noncombatants, Conrad took his army across Anatolia. On 25 October 1147, they were defeated by the Seljuk Turks at the Battle of Dorylaeum. Conrad and most of the knights escaped, but most of the foot soldiers were killed or captured. The remaining 2,000 men of the German army limped on to Nicaea, where many of the survivors deserted and tried to return home. Conrad and his adherents had to be escorted to Lopadium by the French, where they joined the main French army under Louis. Conrad fell seriously ill at Ephesus and was sent to recuperate in Constantinople, where his host the Emperor Manuel I acted as his personal physician. After recovering, Conrad sailed to Acre, and from there reached Jerusalem. He participated in the ill-fated Siege of Damascus and after that failure, grew disaffected with his allies. Another attempt to attack Ascalon failed when Conrad's allies did not appear as promised, then Conrad returned to Germany, through Constantinople, where he met Emperor Manuel I to discuss the problem of two emperors, and to renew their alliance against Roger II of Sicily.
