The next stop on the way to retaking the Holy Land from the Seljuk Turks was Antioch in modern day Syria. This battle took longer than the siege of Nicaea. On the long road to Antioch the crusaders were attacked along the way by the Seljuk Turks. The Seljuk armies were not keen on simply giving up the areas they had worked so vigorously to obtain. Eventually, the crusaders defeated the Seljuk Turks that plagued them during their convoy. Anna Komnena describes this defeat, “This so terrified the Turks that it made them turn their backs. Remembering the Emperor's advice, they did not pursue them far, but reached the Turks' lines and, after resting there a little, overtook them again near Augustopolis, and attacked and routed them utterly. After that the barbarian power collapsed; the survivors dispersed, one here, one there, leaving their wives and children behind them, as for the future they did not dare meet the Latins face to face, but tried to find safety for themselves in flight” (Comnena 2001).
Once the crusaders reached the city of Antioch, they were full of spirit and prepared to conquer another city in the name of the Church. This battle was won with a bit of subterfuge. The leader of the crusaders, Bohemund, spoke often with one of the guards at the walls of Antioch. After some persuasion, the guard agreed to open the gates to Bohemund when asked. After the armies were ready, Bohemund told the guard to open the gates and the crusaders entered the city and overtook it quickly. Anna Komnena offers an interesting description of the conquer, “And then indeed a strange sight was to be seen, the Turks, panic-stricken fled without delay through the opposite gate, and the only ones of them who stayed behind were a few brave men who defended the Cula [*= The citadel]; and the Franks from outside ascended the ladders on the heels of Bohemund, and straightway took possession of the city of Antioch” (Comnena 2001). With this quick thinking and swift action, the crusaders took Antioch.
