Siege of Almería (1309)

Preparation

Aragon's naval preparation was noticed by Granada and at the end of February 1309, and Muhammad III queried James II of Aragon (r. 1291–1327) about the target of the operation. James II responded on 17 March, assuring Granada that it was for his conquest of Sardinia. As tensions rose and Castile's vassals began attacking Granada's borders, the governor of Almería, Abu Maydan Shuayb, arrested Catalan merchants based in his city and confiscating their goods, while the Granadan fleet prepared for war. James II and his ally Ferdinand IV asked Pope Clement V—without mentioning their collaboration with the Marinids—to grant a crusading bull and financial support from the church. The pope granted James II two thirds of the decima—a tenth of church revenues, which can be collected by the monarch if authorized by the pope—for the upcoming crusade against Granada, and declared indulgences for those participating in the war.

To wage war against Granada, James II raised an army with the planned total of 12,000 including 1,000 knights and 2,000 archers. He also raised funds and strengthened the defenses of the Kingdom of Valencia, his realm closest to Granada. His target was Almería, in the southeastern coast of the Emirate of Granada and about 90 miles (140 km) from the capital. James brought along a relic of Indaletius, a saint from the ancient Urci on whose ruins Almería was believed to stand. Aragon did not have an immediate border with the Emirate, so a part of the force was transported by sea and others had to march overland through Castilian territories and then from the Castile–Granada frontiers to Almería via hostile territories.

The city of Almería prepared against a siege by stockpiling food, implementing a ration and strengthening the city's defenses. A Muslim account emphasized the importance of the food supplies, saying that "one of the signs of Allah's protection of the city's inhabitants was that great quantities of barley were in the storehouses at the beginning of the siege". The city's governor, Abu Maydan Shuayb and the naval commander Abu al-Hasan al-Randahi organized the improvement of the city's defense. They strengthened the walls, closed various gaps and demolished outer buildings that might be used by the attackers.

Siege

James II and his forces sailed from Valencia on 18 July 1309 and landed on the coast of Almería on 11 August. A Muslim account emphasized the forces' rich and colorful clothing, and the military instruments played by their musicians. His forces included siege engines such as mangonels and trebuchets. Such a display initially demoralized the defenders, but as time went by and various incidents took place, they became more optimistic.

The besiegers spread their troops to blockade the city by land and sea, and established palisades and ditches. The defenders manned the walls with archers and infantrymen, and barred all the gates with stonework except for some which were to be used for sorties. The late summer arrival was a major disadvantage for the invaders. It meant that there was a short time before the weather got cooler, and if the siege lasted until winter it would be an advantage for the defenders who did not have to be out in the field.

Apart from Almería in the east, the Emirate of Granada had to defend itself from multiple fronts. In North Africa, the Marinids attacked Ceuta in 12 May 1308 and took it on 21 July, while in Granada's western flank, Castile besieged Algeciras (31 July 1309 – January 1310) as well as Gibraltar (August – September 1309). Nevertheless, Nasr sent a relief forces to Almería, which were defeated by the Aragonese in an open battle on 23 August. A Christian account mentioned that the Muslims lost 6,000 men, but modern historian Joseph F. O'Callaghan considered this figure to be exaggerated. Upon hearing the news, Pope Clement V congratulated James on the victory. The defeated relief forces remained in the vicinity, and continued to harass the besiegers.

In late August or early September, the city defenders repelled an assault by the Aragonese forces. The attackers used scaling ladders and siege towers which were loaded with troops and moved by wheels. The defenders resisted by pouring boiling oil and other flammables on the assailants. As a result, one of the siege towers was burnt and the assault was aborted. During the retreat, many assailants were left behind and captured by the Muslims. After this failure, the Aragonese continued to lob rocks weighing up to thirty pounds into the city. The attackers also employed sappers to dig tunnels with the goal of undermining the foundation of the walls, but the defenders employed counter-sappers who found the tunnels. An underground combat ensued which resulted in the destruction of the attackers' tunnels.

In mid or late September, Granada made peace with the Marinids, in exchange for surrendering the western towns of Algeciras (besieged by Castile) and Ronda. Not only did this mean that there was one less enemy for Granada, but the Marinids also took over the responsibilities for defending Algeciras, freeing Nasr to strengthen his eastern flank. On 17 September a Volunteers of the Faith contingent sent from Granada under Uthman ibn Abi al-Ula arrived in Marchena near Almería and defeated a small Aragonese force. This relief contingent camped nearby and continuously frustrated the besiegers by harassing their foraging parties. On 15 October, the Aragonese reported a victory against a Muslim army of 60,000, killing 2,000 and taking others prisoners, numbers considered "surely [..] an exaggeration" by O'Callaghan. James sent warnings of Muslim counter-attacks to his cities of Murcia and Lorca.

As the siege continued, the invaders tried to use a stratagem to trick the defenders. A group of Christian soldiers slipped out in the darkness and then approached the city dressed in burnouses to make the defenders think that they were Muslims. Another group of Christian knights then pretended to give them a chase and to leave their tents unguarded. The tents were made to look as a tempting target for pillage while in fact they were set up for an ambush. A group of riders then came out of the city to pillage the tents, but the Christians came out of their concealed positions too soon, allowing the riders to escape. Most of them managed to reenter the city via the side entrance that happened to be made ready to open the day before, but some were left behind. They then had to stay at the foot of the walls, protected by covering fire from the city. When the fighting died down they reentered the city.

The siege's progress was dominated by the exchange of shots from siege engines. According to Ibn Al-Qadi 22,000 rocks were thrown throughout the siege. The attackers had eleven catapults or other such engines. The Muslims initially had just one, but when this was destroyed by enemy fire they built three more. At the end of December, a section of the walls was breached and the Christians rushed to attack it, but a Muslim force defended the section and stopped them from entering the city.

Truce and Aragonese withdrawal

At the end of the year, the prospect for an Aragonese victory faded. Winter was coming and would endanger their forces in the field. The concurrent siege of Algeciras by Castile was weakening, which allowed Granada to deploy more forces against Aragon. In addition, winds blew from the west and prevented the besiegers from receiving supplies which came by sea from Aragon. The Granadan commander, Uthman ibn Abi al-Ula not only successfully harassed the attackers, but served as a diplomat in negotiations with James II. At the end of December, a parley took place in the Aragonese camp and both sides agreed to a truce. Under the terms of the truce, the Aragonese were to lift the siege and withdraw from Granadan territories. Due to logistical difficulties, such as a lack of vessels to bring the troops home, evacuation took place gradually and some men were left behind under Muslim protection. Some of the demoralized Aragonese tried to go home without authorization and suffered ambushes and attacks along the way, with many captured by the Muslims. At one point during the evacuation, Nasr wrote to James that the city's defenders had to put the remaining Aragonese troops under detention because they were pillaging Granadan territories. Nasr further noted that the Muslims gave them housing and food at their own expense "because some of them were starving" while waiting for the Aragonese ships to pick them up. A rumour of a renewed attack by James II circulated in the city but never materialized. The citizens of Almería removed leftover siege works outside the city walls as precautions. The Aragonese prisoners were later released in the peace settlement.

Aftermath

The defeat of the Aragonese in Almería, as well as the simultaneous defense of Algeciras from Castile, were major successes for Granada. Both Castile and Aragon made peace with Granada by early 1310. According to the historian L. P. Harvey, the particularly humiliating defeat and evacuation of the Aragonese "taught [the Aragonese] a lesson" and delayed the progress of the reconquista for decades. José Ramón Hinojosa Montalvo wrote that "the material and morale failure of the Granada enterprise" caused James II to subsequently redirect his attention to the central Mediterranean, away from Granada. For Granada, the successes in Almería and Algeciras were tempered by the loss of Gibraltar to Castile, as well as the cession of Algeciras and Ronda to the Marinids. Nasr himself became unpopular and faced the rebellion of his brother-in-law Abu Said Faraj and nephew Ismail in 1311, which resulted in his dethronement and the accession of Ismail in 1314.
