Final answer:
The Crusaders likely experienced a mix of emotions, including a sense of betrayal, frustration, and anger due to the failure of the promised assistance from the Byzantine Empire, undermining their mission and objectives.
Step-by-step explanation:
The Crusaders embarked on their expedition with expectations of Byzantine support, promised in exchange for their aid in recapturing territory from the Seljuk Turks. The absence of the anticipated reinforcement and the diversion of their efforts towards a different objective likely left them feeling betrayed and frustrated. Their cause, initially aligned with the Byzantine Empire's interests, was compromised, leading to a sense of abandonment and potentially instigating anger among the Crusaders. This betrayal could have strained their morale and trust in future alliances, affecting their fervor and dedication to the overall mission.
