Siege of Jacob's Ford

History

Jacob's Ford is approximately one hundred miles north of Jerusalem at the Jordan River and was a key river crossing on one of the main roads between Acre and Damascus. Jacob's Ford was also one of the safest crossings of the Jordan and, because of its location and importance, was utilized by Christian Palestine and Muslim Syria as a major intersection between the two civilizations. In the twelfth century, Baldwin and Saladin continually contested over the area on which Jacob's Ford was situated. As a bold strategic move and as a result of his military victory at Montgodard, Baldwin decided to march to Jacob's Ford and build a defensive fortress on its territory. The King Baldwin IV of Jerusalem and his Crusaders theorized that such a fortification could protect Jerusalem from a northern invasion and put pressure on Saladin's stronghold at Damascus.

Between October 1178 and April 1179, Baldwin IV began the first stages of constructing his new line of defense, a fortification called Chastelet. While construction was in progress, Saladin became fully aware of the task he would have to overcome at Jacob's Ford if he were to protect Syria and conquer Jerusalem. At the time, he was unable to stop the erection of Chastelet by military force because a large portion of his troops were stationed in northern Syria, putting down Muslim rebellions. As one author writes, "Saladin was always at pains to portray himself as the champion of Islam against the European intruders, although in fact he spent much of, if not more, of his career involved in a war against other Muslims." Consequently, the sultan turned to bribery and offered Baldwin 60,000 dinars to halt construction. Baldwin declined, but Saladin made a counter-offer of 100,000 dinars. The Christian King Baldwin IV of Jerusalem refused again and continued to build Chastelet. By the summer of 1179, Baldwin's forces had constructed a stone wall of massive proportions. "The Castle now had a formidable ten met[er] high wall – what one Arabic contemporary later described as ‘an impregnable rampart of stone and iron’ – and a single tower, but it was still a work in progress." In April 1179, Baldwin gave command of Jacob's Ford to the Knights Templar.

Plans and tactics

After Baldwin IV refused both bribes, Saladin turned his attention away from the uprisings in northern Syria and focused on Jacob's Ford and the Castle of Chastelet. He was fully aware that any further bargaining or negotiations would only be in vain and that the more time he wasted, the more time Baldwin IV would have to complete his massive fortification. In 1179, only a few months after construction of Chastelet began, Saladin summoned a large Muslim army to march southeast towards Jacob’s Ford. The plan was simple: lay siege to the castle and its inhabitants before any reinforcements from Jerusalem or any of its neighboring territories could arrive.

Baldwin IV of Jerusalem, on the other hand, was situated at Tiberias, a province situated on the Sea of Galilee, approximately a half day's march from Jacob's Ford. Tiberias was 65–75 km away by road or path. If any attack were to befall his project, reinforcements would be able to arrive relatively quickly. Moreover, the fortification at Jacob’s Ford, at least what was completed of it, was relatively strong and was likely able to hold out until relief could arrive in case of siege. As one Crusades author asserts and inquisitively asks, "[t]he siege was effectively a race – could the Muslims crack the stronghold's defenses before the Latin forces arrived?"

Siege

On 23 August 1179, Saladin arrived at Jacob's Ford and ordered his troops to shoot arrows at the castle, thus initiating the siege. While the archers distracted the men inside the fortification, miners were digging a tunnel to breach the stone and iron walls at the north-east corner of Chastelet. Once the tunnel was dug, Saladin's forces placed large amounts of wood inside and set it alight. This process, called sapping, was a method in which the tunnel's supports were burnt away forcing the walls to eventually collapse under their own weight. The walls didn't collapse, because the tunnel was too narrow. Sapping initially failed for Saladin and his troops, so the troops were forced to put out the fire with buckets of water and were paid one gold piece per bucket to do so. After the fire was extinguished, the miners were instructed to broaden the tunnel and eventually relight the fire. At the same time, King Baldwin IV, having learned of this attack, called for reinforcements from Jerusalem. However, communications between Baldwin and Chastelet were slow and, by this time, the siege had been under way for several days. The identity of the Templar Castellan remains unknown.

The Templar Castellan's forces inside the castle began to reinforce the main gates around the Castle. Shortly after, the Muslims relit the fire in the tunnel under the castle, and the walls collapsed. As a result, the Crusaders' attempts to refortify the castle were in vain and, approximately six days after the siege began, Saladin and his troops entered Chastelet. By 30 August 1179, the Muslim invaders had pillaged the castle at Jacob's Ford and killed most of its residents. On the same day, less than one week after reinforcements were called, Baldwin IV of Jerusalem and his supporting army set out from Tiberias, only to discover smoke permeating the horizon directly above Chastelet. Obviously, they were too late to save the 700 Knights, architects, and construction workers who were killed and the other 800 who were taken captive. Baldwin and his reinforcements turned back towards Tiberias and Saladin ordered the remains of the fortification to be torn down.

Aftermath

Although Saladin claimed a military victory at Chastelet, his troops fell victim to another enemy. Directly after the siege, the bodies of the 700 Crusaders killed at Jacob's Ford were placed into a pit. The corpses in the pit began to decay in the August heat and, as a result, a plague ensued, killing approximately ten of Saladin's senior officers. However, this setback did not diminish Saladin's military prowess. In 1180, Saladin and Baldwin signed a truce. Seven years after this peace treaty between the Muslims and the Christians, Saladin captured Jerusalem from the Crusaders after the Battle of Hattin in 1187.

Some scholars suggest that, following Saladin's victory at Jacob's Ford in 1179, Jerusalem was extremely vulnerable to capture because "the entry into the Kingdom of Jerusalem by way of the Jordan crossing immediately south of Lake Tiberias, used [by] Saladin in 1182, 1184, and 1187 was virtually undefended". However, that crossing has nothing to do with the more northerly Jacob's Ford, and beside that it was only some ten kilometres south from the fortified and garrisoned Crusader town of Tiberias, capital of the Principality of Galilee, this being one among several Crusader strongholds in the eastern Galilee and Jordan Valley, which leaves space for debate.

After the capture of Jerusalem, Saladin remained militarily and politically successful in the Near East until a military encounter with Richard the Lionheart, after which he was forced to make peace in 1192. He died the next year. Meanwhile, King Baldwin IV, afflicted with leprosy, died in 1185 at age twenty-three.
