First Crusade participant Tatikios
Siege of Nicaea
The Crusader armies crossed over into Asia Minor during the first half of 1097, where they were joined by Peter the Hermit and the remainder of his relatively small army. In addition, Alexios also sent two of his own generals, Manuel Boutoumites and Tatikios, to assist the crusaders. The first objective of their campaign was Nicaea, a city once under Byzantine rule, but which had become the capital of the Seljuk Sultanate of Rûm under Kilij Arslan. Arslan was away campaigning against the Danishmends in central Anatolia at the time, and had left behind his treasury and his family, underestimating the strength of these new crusaders.Subsequently, upon the Crusaders' arrival, the city was subjected to a lengthy siege, and when Arslan had word of it he rushed back to Nicaea and attacked the crusader army on 16 May. He was driven back by the unexpectedly large crusader force, with heavy losses being suffered on both sides in the ensuing battle. The siege continued, but the crusaders had little success as they found they could not blockade Lake İznik, which the city was situated on, and from which it could be provisioned. To break the city, Alexios had the Crusaders' ships rolled over land on logs, and at the sight of them the Turkish garrison finally surrendered on 18 June.There was some discontent amongst the Franks who were forbidden from looting the city. This was ameliorated by Alexius financially rewarding the crusaders. Later chronicles exaggerate tension between the Greeks and Franks but Stephen of Blois, in a letter to his wife Adela of Blois confirms goodwill and cooperation continued at this point. The fall of Nicaea is viewed as a rare product of close co-operation between the Crusaders and the Byzantines.Battle of Dorylaeum
At the end of June, the crusaders marched on through Anatolia. They were accompanied by some Byzantine troops under Tatikios, and still harboured the hope that Alexios would send a full Byzantine army after them. They also divided the army into two more-easily managed groups—one contingent led by the Normans, the other by the French. The two groups intended to meet again at Dorylaeum, but on 1 July the Normans, who had marched ahead of the French, were attacked by Kilij Arslan. Arslan had gathered a much larger army than he previously had after his defeat at Nicaea, and now surrounded the Normans with his fast-moving mounted archers. The Normans "deployed in a tight-knit defensive formation", surrounding all their equipment and the non-combatants who had followed them along the journey, and sent for help from the other group. When the French arrived, Godfrey broke through the Turkish lines and the legate Adhemar outflanked the Turks from the rear. The Turks, who had expected to destroy the Normans and did not anticipate the quick arrival of the French, fled rather than face the combined crusader army.The crusaders' march through Anatolia was thereafter unopposed, but the journey was unpleasant, as Arslan had burned and destroyed everything he left behind in his army's flight. It was the middle of summer, and the crusaders had very little food and water; many men and horses died. Fellow Christians sometimes gave them gifts of food and money, but more often than not, the crusaders simply looted and pillaged whenever the opportunity presented itself. Individual leaders continued to dispute the overall leadership, although none of them were powerful enough to take command on their own, as Adhemar was always recognized as the spiritual leader.
