Camp, Garrison and Siege Life in the Crusader Era

From the First Crusade’s passage through Anatolia and the Levant in 1096–1099 to the siege of Acre in 1189–1191, Crusader armies spent much of their time moving, encamping, or waiting outside fortified places. These settings were not interchangeable. A mobile host had to find food and water along its route; a siege camp might remain in one place for months; and a garrison, the force assigned to defend a city or fortress, had to hold its position under attack. Long sieges turned obtaining provisions, protecting supply routes, constructing defences and caring for sick companions into daily work.

Temporary camps and the people in them

Crusading armies included more than knights and foot soldiers. Non-combatants travelled with the forces, and the estimated numbers at Antioch in 1097 included them as well as armed participants. The groups making up an army could also differ in experience and resources. The poorly supplied People’s Crusade of 1096 was distinct from the later expedition led by princes and their followings; both faced the practical demands of feeding and moving large groups.

Accounts place camps in relation to nearby gates, rivers and roads. During the siege of Antioch, which began in October 1097, the Crusader contingents camped at different points outside the city. At Jerusalem in 1099, Godfrey of Bouillon and Tancred camped north of the city, while Raymond of Toulouse established his force to the south. The separate camps followed the armies’ contingent leadership and divided responsibility for watching the approaches and carrying out assaults.

Participants who took the crusading vow usually wore a cross sewn onto their clothing. The sewn cross made the wearer’s religious commitment visible. People, animals and equipment travelled together: obtaining food and fodder could determine how long an army remained able to operate in one place.

Finding supplies and doing the work

Foraging was a recurring task, but it became harder when an army had exhausted the nearby countryside. At Antioch, the Crusaders initially gathered food in the surrounding area. As supplies dwindled, their parties had to range farther and faced greater danger from nearby defenders. Local Christians sometimes brought food, but charged high prices. Supplies also arrived by sea through ports including St Symeon, and from areas such as Cilicia and Edessa. These routes could ease shortages, but moving goods from a port to the camp still exposed people and supplies to attack.

The need to obtain provisions affected soldiers and animals alike. During the First Crusade’s march through Anatolia, the army suffered from shortages of both food and water, and many people and horses died. At Antioch, by early 1098 the Crusaders had lost so many horses that only about 700 remained, making continued campaigning more difficult. The poorest members of the force were particularly exposed to hunger.

Camp life also involved building and repair. In 1099, Genoese mariners who arrived at Jaffa brought skilled engineers and timber taken from their ships. The material helped the Crusaders construct siege engines for the assault on Jerusalem. At Antioch, Crusaders built a fortification near Saint Paul’s Gate and another position intended to block the Bridge Gate. They also repaired an abandoned monastery west of the Gate of Saint George and used it to help protect a supply route. Such work required materials and skilled labour as well as the effort of the larger force.

Waiting and hardship at Antioch

The siege of Antioch lasted from October 1097 until June 1098, followed by a second siege in which the Crusaders, now inside the city, were themselves surrounded. The city’s defences made a quick assault seem unlikely, while the Crusaders did not have enough men to seal every approach. For months, the army had to maintain positions, seek supplies and respond to attacks from the garrison. The defenders sometimes sallied out from the city, making the nearby camp a dangerous place to forage and work.

Winter brought cold rain as well as shortages. Food became so scarce that starvation killed many Crusaders; contemporary accounts give differing estimates of the scale. The bishop Adhemar of Le Puy ordered a three-day fast as a religious response to the army’s distress. Some people deserted, including Peter the Hermit, but were brought back. This was not simply a pause between military actions: maintaining the army’s strength, securing supplies and keeping people from leaving were ongoing concerns.

After the Crusaders entered Antioch on 3 June 1098, they did not control the entire city. Turkish defenders held the citadel, and Kerbogha’s relief army surrounded the Crusader-held part of Antioch later that month. The city’s changing status shows how quickly a besieging force could become a besieged garrison. The Crusaders eventually left the city to fight Kerbogha’s army on 28 June, after which the citadel’s defenders surrendered.

Acre’s double siege and garrison life

At Acre, Guy of Lusignan’s Crusader force arrived in August 1189 and established a camp outside the city after its defences resisted an initial assault. As reinforcements arrived, the Crusaders tightened their land and sea blockade. Saladin’s army, in turn, surrounded the Crusader camp. The result was a prolonged double siege: the defenders in Acre faced the Crusaders, while the Crusaders had to defend their own encampment against Saladin’s forces.

The sea remained a vital route for both sides. Ships brought food and weapons into Acre at points during the siege, while Crusader reinforcements and supplies also arrived by sea. The fighting did not prevent the work of maintaining equipment and fortifications. Siege engines were built or brought to the camp, and attacks that damaged Acre’s walls were followed by efforts from the defenders to repair them. In January 1191, Saladin’s troops broke through the Crusader lines and replaced some of the city’s exhausted defenders with fresh men.

Conditions deteriorated in both the city and the Crusader camp. Food was limited, water was contaminated by human and animal corpses, and disease spread. Many people died from illness rather than in combat. When Acre surrendered in July 1191, the Crusaders repaired its defences. The contrast with the improvised camp outside the city was sharp: the besieging force had become a garrison responsible for holding the captured port.

How camp, siege and garrison life differed

On the march, a Crusader host depended on movement and on finding provisions along its route. A siege fixed the army in place, turning foraging, construction, supply transport and the protection of camp positions into persistent demands. A garrison’s task was different: it had to defend walls and gates, endure shortages, and repair damage while relief forces or besiegers pressed the city. Antioch and Acre illustrate these changes particularly well, with defenders inside walls and besiegers outside facing different tasks and supply routes. In each setting, daily survival depended not only on fighting, but also on whether people could secure food, maintain defences and remain in place through long periods of uncertainty.
