When Pope Eugene III called for a Second Crusade in 1148 after the fall of Edessa, France and Germany responded. It would seem to be easier now, since the First Crusade established a foothold in the Middle East. The German forces were led by King Conrad III. They arrived in Jerusalem in April and met Baldwin (a male needed to lead the military, so this was one official function Melisende could not perform), along with the Templars.
Because Edessa had been so thoroughly damaged that it would be difficult to defend if re-taken, the Crusaders decided to attack and conquer Damascus instead. Damascus was controlled by Unur, an ally of the Kingdom of Jerusalem, so Melisende should have been against this course of action. If Baldwin could lead the army along with the Crusade on a successful military mission, his people would see his value and he could become more popular than his mother.
Melisende went with the army to Palmarea, one of their cities near Acre, where on 24 June 1148 they met up with the French contingent led by King Louis VII, who was accompanied by his wife, Eleanor of Aquitaine. All agreed to lay siege to Damascus.
They first approached Darayya, a city a few miles southwest from Damascus, but for some reason did not conquer it, deciding instead to move southeast of Damascus. This new location had little in the way of provisions or even water, and behind them Muslim forces prevented them from going back to Darayya. With the news that more Muslim forces were approaching, and with constant attacks on their hastily constructed defenses, the Crusaders started to panic. They retreated in disorder to save their lives.
Accusations of betrayal arose. Michael the Syrian (1126 - 1199), the Syriac Orthodox Patriarch of Antioch, wrote that Damascus had offered Baldwin 200,000 gold dinars if he could get the Crusade to withdraw from Damascus. The story continues that the dinars were delivered, only to turn out to be gold-plated copper. (There is no proof of this story.)
The failure of the attempted Siege of Damascus (pictured) gave Melisende the opportunity to further reduce Baldwin's authority. Charters after this do not even carry his name.
It was only a year later that he tried, again, to manage a military campaign. Would it surprise you that he was unsuccessful? His mother's confidence in him was steadily deteriorating. A serious clash was forthcoming, which we will see forming tomorrow.
