Berthold withdrew by spring 1191 and returned home, but Werner remained in the Holy Land.
In May 1206 one Otto von Henneberg issued a certificate with "Wernerus de Egisheim" as a witness.
[2] From September 1210 Werner and Philip of Ibelin were responsible for the defence of Acre whilst the rest of the Crusader nobility attended the coronation of Maria of Montferrat and John of Brienne in Tyre.
In 1218 he and troops from the Republic of Genoa unsuccessfully tried to defend Caesarea from an Ayyubid assault.
[3] Before Frederick II (who took the regency of the Kingdom of Jerusalem in his son's name) ended his crusade and returned to Italy, he appointed Werner and Balian of Sidon his deputies or bailiffs in the Kingdom, with Werner in Acre and Balian in Tyre.
