What problems did the crusaders have on their journey?

The Crusaders faced numerous challenges on their journeys, including harsh weather conditions, difficult terrain, and inadequate supplies, which often led to hunger and disease. They also encountered hostile local populations and rival factions, which impeded their progress and sometimes resulted in conflict. Additionally, the lack of coordinated leadership and differing motivations among various factions created internal strife and weakened their efforts. These obstacles significantly hindered their ability to achieve their goals.
