Why do you think the crusaders traveled by both land and sea?

Crusaders traveled by both land and sea to maximize their strategic options and adapt to different challenges along their journey. The sea routes allowed them to bypass heavily fortified regions and reduce the risk of ambushes, while land routes provided direct access to key territories and resources. Additionally, using both methods helped to transport troops and supplies more efficiently, ensuring better coordination and support during military campaigns. Ultimately, this dual approach enhanced their chances of success in reaching and capturing their objectives in the Holy Land.
