 On 22 September 1197 a substantial German army under the command of Archchancellor Conrad of Mainz and Marshal Henry of Kalden landed at Acre, where their presence aroused the displeasure of the French forces of Queen Isabella of Jerusalem.As the German Princes denied the authority of Henry of Kalden, they elected Duke Henry of Brabant their commander and the crusaders proceeded to Tyre, initiating a campaign to expel the Muslims from Beirut and to subject the Levant coast up to Tripoli.They captured the wealthy and important city of Sidon and on October 24 entered Beirut.
