Answer:
This army was led by Kerbogha, who was the Atabeg of Mosul.
Explanation:
- Kerbogha, after obtaining approval from the Caliph in Baghdad, mustered a large army and went to war.
- However, he made the crucial mistake of not going immediately to Antioch but to Edessa.
- In Edessa, Baldwin Bouillon established his principality after separating from the Crusade.
- Kerbogha therefore wanted to conquer Edessa first and then to Antioch. Edessa was a tough nut after all, and after three lost weeks trying to conquer Kerbogha, he gave up and headed for Antioch.
- Because of this, he was late and came when the city had already fallen into the hands of the cruisers.
