Answer/Explanation:
Four armies of Crusaders were formed from troops of different Western European regions, led by Raymond of Saint-Gilles, Godfrey of Bouillon, Hugh of Vermandois and Bohemond of Taranto (with his nephew Tancred). These groups departed for Byzantium in August 1096.
After Louis and Conrad managed to assemble their armies at Jerusalem, they decided to attack the Syrian stronghold of Damascus with an army of some 50,000 (the largest Crusader force yet).
