Jacob's Ford, 1179

In 1178–79 King Baldwin IV of Jerusalem and the Knights Templar raised a new castle, Chastellet, at Jacob's Ford on the upper Jordan, the main crossing between Damascus and Galilee. Saladin, who had tried to buy the work off, besieged it on about 24 August 1179 with a large army. His archers swept the walls while miners dug under the north-eastern corner; after one failed fire the mine was widened and re-fired, and at dawn on 29 August the wall collapsed. The garrison — perhaps 1,500 people including builders — was killed or taken; about 700 prisoners are recorded. Baldwin's relief army from Tiberias arrived too late, and Saladin pulled the unfinished castle down. Its excavation, with the bones of its defenders still in the ruins, is one of the most vivid archaeological records of a crusader-era siege. Numbers are uncertain: medieval figures are often inflated.

The battle, stage by stage

  1. October 1178 – August 1179

    A castle at the ford

    In October 1178 King Baldwin IV of Jerusalem and the Knights Templar began a castle on a low tell on the west bank of the upper Jordan, overlooking Jacob's Ford (Vadum Iacob) — the crossing of the main road from Damascus into Galilee, a day's march from Saladin's capital. William of Tyre calls it a square fortress of solid masonry of marvellous thickness, built in six months; Saladin reportedly offered 60,000 and then 100,000 dinars to have the work stopped, and was refused. The excavation shows it was still a building site: an outer curtain about 128 x 61 m with walls rising toward 10 m, a gate in the south wall, a postern on the east and one small tower, the inner vaults barely begun, tools and a heap of lime left where the workers stood. In April 1179 the king handed it to the Templars. In June, after Saladin's victory at Marj Ayyun (10 June), where the Templar Master Odo of Saint-Amand was captured, the castle was more exposed than ever.

  2. 23–24 August 1179

    Saladin comes to the ford

    Saladin brings his field army south from the Banias district to the ford; chroniclers on both sides call it large but give no reliable figure. Imad al-Din says parties were sent into the Safad district to cut vine-poles and timber for palisades to shield the mangonels. Inside the castle, by the account of al-Qadi al-Fadil, were 80 knights with their squires, fifteen captains each with fifty men, artisans and about 100 Muslim captives — perhaps 1,500 people in all. King Baldwin was gathering an army at Tiberias, about half a day's march to the south.

  3. Saturday 24 August 1179

    The outer compound falls

    Saladin's archers open the siege from both banks; hundreds of arrowheads have been found along the east and west fronts. On the first day the outer works were taken — Ibn al-Athir credits a commoner in a ragged tunic with being first onto the wall — and the defenders pulled back inside the curtain. To hold the entrances they lit fires behind the gates. The south gate faced the ford about 200 m away; the Jordan, here narrow and shallow, ran along the east side.

  4. 25–28 August 1179

    Mining the north-east corner

    While the archers kept the defenders' heads down, Saladin's miners dug under the north-eastern corner of the wall (the excavated breach; some readers of Imad al-Din place the mine under a tower). By Sunday night they packed the gallery with timber and fired it, but the wall — reportedly some nine cubits thick — held. Saladin is said to have paid a gold dinar for every skin of water brought to douse the fire so the miners could go back in, widen the tunnel and fire it again.

  5. Dawn, Thursday 29 August 1179

    The wall comes down

    At daybreak the props burned through and the north-eastern corner collapsed into the mine. Imad al-Din writes that the fire spread to the Franks' tents inside, and Saladin's troops poured through the breach. By al-Fadil's account the Templar commander threw himself into the flames rather than be taken. The excavators found skeletons of men killed in the fighting — a skull with three sword cuts, an arm severed above the elbow, wounds from arrows — along with dead horses and mules. Saladin had apostates and the bowmen among the prisoners put to death; about 1,000 mail coats were taken as plunder.

  6. 29–30 August 1179

    Too late from Tiberias

    Baldwin's relief army had only just set out from Tiberias when the smoke rising over the ford told them the castle had fallen; the Latin sources blame slow muster and slow messages, and the king turned back (how far north he came is not recorded). Imad al-Din counts about 700 prisoners; many were killed on the road by volunteers before the rest reached Damascus. Figures differ — some modern accounts give about 800 dead and 700 captured.

  7. September – mid-October 1179

    Pulling down the castle

    Saladin stayed to dismantle the walls stone by stone. The dead were thrown into the castle's cistern (never located; a pit about 4 m across has been found some 50 m north of the walls); in the late-summer heat disease broke out in his camp and reportedly killed ten of his emirs. A truce followed in 1180. The ruin was split by the 1202 earthquake — the north and south walls are offset by about 2 m along the Jordan fault — and from 1993 Ronnie Ellenblum's excavation (published by Kate Raphael, Israel Exploration Society, 2023) recovered the arrowheads, tools, coins and the bones of the garrison.

Weapons

Ayyubid army (Saladin)

Turkish composite bow

Turkish composite bow

Recurved composite bow · in use for many centuries

At Jacob's Ford: Hundreds of arrowheads were recovered along the castle's east and west fronts.

Small, very strong recurved bows built up from horn, wood and sinew. Mounted archers could shoot them at the gallop and wheel away before a charge reached them, the tactic that wore down Crusader columns on the march.

Build
horn, wood and sinew, glued and bound
Use
shot from horseback at the gallop
Range
effective to about 100–150 yd; farther for volleys

Trebuchet and mangonel

Trebuchet and mangonel

Stone-throwing siege engine · traction type from the 6th c.; counterweight type from the 12th c.

At Jacob's Ford: Mangonels were set up behind palisades of vine-poles cut in the Safad district.

A long throwing arm on a pivot hurled stones from a sling. Crews hauling on ropes powered the older traction engines; the counterweight trebuchet, spreading in the late 12th century, threw much heavier stones and could bring down walls.

Power
crew hauling ropes (traction) or a heavy counterweight
Missile
stones of several kilograms up to over 100 kg
Use
battering walls and towers

Straight Islamic sword (sayf)

Straight Islamic sword (sayf)

Straight, mostly double-edged sword · in use for centuries; curved sabres spread later

At Jacob's Ford: The storming parties went through the breach with sword and shield.

Saladin's horsemen fought with straight swords much like the Franks', alongside lance, mace and bow. The curved sabre popularly linked with the Crusades became widespread in the Middle East mainly after the 13th century. This sword is a 13th-century Mamluk example.

Blade
straight, about 80–90 cm
Use
cavalry and infantry sidearm
Note
the curved scimitar of legend became common only after this period

Templar garrison (Kingdom of Jerusalem)

Crossbow

Crossbow

Mechanical bow · about 1100–1500 in Western armies

At Jacob's Ford: The garrison's crossbowmen were singled out for execution after the castle fell.

A short, powerful bow mounted on a stock and spanned with the feet or a hook, shooting a heavy bolt. It took less skill than a longbow and outranged the Turkish horse archer's bow at close quarters, so Crusader armies used crossbowmen to screen their knights.

Draw
spanned by foot stirrup or belt hook
Range
effective to about 150–200 yd
Rate
about 2 bolts a minute

Mailed knight and couched lance

Mailed knight and couched lance

Heavy cavalry · 11th–13th centuries

At Jacob's Ford: About 1,000 mail coats were taken as plunder; the excavated skeletons show sword and arrow wounds.

With the lance couched under the arm, a knight put the weight of man and horse behind the point. A massed charge could break almost any enemy that stood to receive it, so Muslim commanders tried to avoid it, scattering and shooting at the horses instead.

Armour
mail hauberk, helmet, kite or heater shield
Weapon
lance held under the arm, then sword or mace
Weakness
unarmoured horses; heat and thirst

Mail hauberk and kite shield

Body armour and shield · 11th–13th centuries

At Jacob's Ford: About 1,000 mail coats were taken as plunder from the garrison.

A knee-length shirt of riveted iron rings over a padded coat, with a long shield covering the left side. It stopped most cuts and many arrows; chroniclers describe Crusader foot soldiers marching on with arrows stuck in their mail. Heat and thirst were its cost.

Mail
thousands of riveted iron rings, about 10–15 kg
Shield
tall, kite- or flat-topped, wood faced with leather
Under
a padded gambeson

Knightly sword (arming sword)

Knightly sword (arming sword)

Straight, double-edged sword · 10th–14th centuries

At Jacob's Ford: The excavated skeletons show sword cuts, including a skull struck three times.

The knight's sidearm once the lance had broken: a broad, double-edged cutting blade with a simple cross guard and a disc or brazil-nut pommel. Swords were costly, prized and often blessed, and the cross shape of the hilt was not lost on men who had taken the cross.

Blade
about 75–90 cm, broad and fullered
Weight
about 1–1.4 kg
Use
one-handed, with a shield, on foot or horseback
