Battle of Ba'rin

In the Battle of Ba'rin (Mont Ferrand) in 1137, a Crusader force commanded by King Fulk of Jerusalem was scattered and defeated by Zengi, the atabeg of Mosul and Aleppo. This setback resulted in the permanent loss of the Crusader castle of Baarin.

Background
When Zengi became ruler of Mosul in 1127 and Aleppo in 1128, the Crusaders were faced with a dangerous opponent. For several years afterward, Zengi gained power at the expense of neighboring Muslim states. By occasionally allying itself with the Latin Kingdom of Jerusalem, the Muslim emirate of Damascus successfully resisted Zengi's efforts to conquer that city.

Battle
In early 1137, Zengi invested the castle of Ba'rin, about 10 miles northwest of Homs. When King Fulk marched with his host to raise the siege, his army was attacked and scattered by Zengi's forces. Nothing is known about the battle. The Christian chronicler William of Tyre "gave no tactical information, and neither did the Arab historians."

After their defeat, Fulk and some of the survivors took refuge in Ba'rin castle, which Zengi surrounded again. "When they ran out of food they ate their horses, and then they were forced to ask for terms." Meanwhile, large numbers of Christian pilgrims had rallied to the army of Byzantine Emperor John II Comnenus, Raymond of Antioch and Joscelin II of Edessa.

With this host approaching the castle, Zengi suddenly granted Fulk and the other besieged Franks terms. In return for their freedom and evacuation of the castle, a ransom was set at 50000 dinar. The Franks, unaware of the imminent arrival of the large relieving army, accepted Zengi's offer.

Aftermath
In April 1137, John Comnenus laid siege to Shaizar but his efforts came to nothing when Zengi relieved the city in May. Ba'rin was never recovered by the Franks.
