Foulque of Anjou, after having re-established peace among his neighbours, found, on his return, that discord not only prevailed in his states, but had even made its way into his own house. Walter, count of Cæsarea, accused Hugh, count of Jaffa, of the crime of treason towards his king. This latter noble had drawn upon himself the hatred of the king and the principal people of the kingdom, some say by his pride and disobedience, and others by his guilty connection with the queen Melisende. When the barons had heard Walter of Cæsarea, they decided that a battle, _en champ clos_, should take place between the accused and the accuser; and as the count of Jaffa did not appear in the lists on the day nominated, he was declared guilty. Hugh was descended from the famous lord of Puyset, who raised the standard of revolt against the king of France, and who, conquered in the end by Louis le Gros,[255] despoiled of his possessions and banished his country, had taken refuge in Palestine, where his exploits had secured him the county of Jaffa, which he had transmitted to his son. Hugh possessed the turbulent and impetuous character of his father, and, like him, could neither pardon an injury nor submit to an act of authority. On learning that he was condemned without being heard, he set no bounds to his anger, but hastened immediately to Ascalon, to implore the aid of the infidels against the Christians. The Mussulmans, highly pleased with the division which had sprung up among their enemies, at once took the field, and ravaged the country as far as the city of Asur. Hugh, after having contracted a criminal alliance with the Saracens, shut himself up in Jaffa, where he was soon besieged by the king of Jerusalem.
