In 1215, Pope Innocent III held a council on November 1215 to declare a new crusade, calling to liberate the Christian prisoners and to capture the Muslim fortress at Mount Tabor.

The Hungarian king, Andrew II, and the Austrian Duke, Leopold VI, answered the call and began assembling and equipping their armies.

[3] The Austrian and Hungarian armies, along with the King of Jerusalem, Cyprus, Antiochian troops, and the three military orders, launched an offensive to enhance the security of Acre.

It was regarded by Muslims as unconquerable, and only the help of a local convert boy who knew a hidden path to the fort encouraged the Crusaders to attack it.

[7][8][9][10] Upon their descent, King John held a council with the Master of Hospitallers and Bohemond, along with the Syrian Barons, who both had disputes regarding the continuation of the siege.

Disheartened by this failure, the Crusaders decided to abandon the siege, and on December 7, they withdrew from Mount Tabor and headed to Acre.
