Final answer:
During the First Crusade, the Crusaders were organized into different groups and contingents led by various leaders for their march down the coast to Jaffa. These groups coordinated their movements to proceed together.
Step-by-step explanation:
The Crusaders were organized into armies for their march down the coast to Jaffa during the First Crusade. The armies consisted of different groups and leaders who led their own contingents. The crusaders traveled in a linear fashion, rather than in a single unified group, due to the large number of people involved and the need to gather supplies and avoid ambushes.
Some of the groups included the armies of Godfrey of Bouillon, Raymond of Toulouse, Bohemond of Taranto, and Tancred. Each group had their own leaders and strategies, but they ultimately coordinated their movements to proceed down the coast together.
