Above and beyond any reliance on castles, however, Sultan Baybars regarded the army as the bedrock of the Mamluk state. Adopting and extending the existing system of mamluk recruitment, he purchased thousands of young male slaves, drawn from Kipchak Turkish and, later, Caucasian stock. These boys were trained and indoctrinated as mamluk troops, and then at the age of eighteen freed to serve their masters within the Mamluk sultanate. This approach created a constantly self-rejuvenating military force–what one modern historian has called a ‘one-generation nobility’–because children born of mamluks were not regarded as being part of the martial elite, although they were permitted to enrol in the army’s second-tier halqa reserves.

Baybars ploughed massive financial reserves into building, training and refining the Mamluk army. In total, the number of mamluks was increased fourfold, to around 40,000 mounted troops. The core of this force was the 4,000-strong royal mamluk regiment–Baybars’ new elite, schooled and honed in a special practice facility within the citadel of Cairo. Here recruits were taught the arts of swordsmanship–learning to deliver precise strikes by repeating the same cut up to 1,000 times a day–and horse archery with powerful composite recurve bows. The sultan emphasised rigid discipline and rigorous military drilling across every section of the Mamluk host. In the course of his reign, two massive hippodromes were constructed in Cairo–training arenas where the essential skills of horsemanship and combat could be perfected. Whenever in the capital, Baybars himself came daily to practise the warrior craft, setting a standard of professionalism and dedication. His mamluks were encouraged to experiment with new weapons and techniques, some archers even attempting to use arrows doused in Greek fire from horseback.10

Once of adult age, mamluks were paid, but also were expected to maintain their own horses, armour and weaponry. To ensure his forces were outfitted properly, Baybars instituted troop reviews, in which the entire army, in full martial regalia, would parade past the sultan in a single day (in part to ensure that equipment was not being shared). Failure to attend these displays was punishable by death. Fear was also used to maintain order while on campaign. The drinking of wine was banned on many expeditions, and any soldier caught contravening this injunction was summarily hanged.

To reinforce the human component of the Mamluk armed forces, Baybars invested in some forms of heavier armament. Close attention was paid to the development of siege weaponry, including sophisticated counter-weight catapults, or trebuchets. These engines became the mainstay of Mamluk siegecraft. Capable of being dismantled, borne to a target and then readily reconstructed, the largest could propel stones weighing in excess of 500 pounds. In addition to raw military power, Baybars also placed great value upon accurate and up-to-date intelligence. He therefore maintained an extensive network of spies and scouts across the Near East and received reports from agents embedded in Mongol and Frankish societies. The sultan also showed generous patronage to the nomadic Bedouin Arabs of the Levant, and thereby won their valuable support, both in military conflicts and in the gathering of information.

Through these diverse methods, Baybars constructed the most formidable Muslim army of the crusading era; a force more numerous, disciplined and ferocious than any yet encountered in the war for the Holy Land–the perfect military machine of its day.11 Having carefully legitimised and consolidated his hold on power, the sultan turned in 1265, with a united Islamic Near East behind him, to wield this deadly weapon in the name of jihad.

THE WAR AGAINST THE FRANKS

Unlike his Ayyubid predecessors, Sultan Baybars showed little or no interest in reaching an accommodation with Outremer. Rather than appease the Franks to preserve commercial links and stave off a western European crusade, he sought simply and completely to eradicate the Latin presence in the Levant. Baybars calculated that, by this means, the flow of trade might be forced back through Mamluk Egypt and that, with no bridgehead in the Holy Land, any attempts by the West to mount an invasion would surely fail. The sultan was always conscious of the need to maintain a watchful eye on the Mongol threat, but this did not prevent him from initiating a series of merciless strikes against the crusader states.

While the work of preparation proceeded apace in the Mamluk world through the early 1260s, Baybars carried out a number of incidental exploratory raids into Frankish Palestine, the only notable product of which was the destruction of the church in Nazareth. To preclude any premature outbreak of full-scale hostilities, the sultan agreed to some limited truces with various factions within the Latin kingdom–a realm that was now in an appallingly disunited and feeble state. The most useful pact was that forged with John of Ibelin, count of Jaffa, one of the last great barons of Outremer. In 1261, Baybars accepted John’s entreaties for peace, and in return used the port at Jaffa to transport grain supplies from Egypt to Mamluk territories in Palestine. By 1265, however, with the Mongol siege of al-Bira having faltered, Baybars’ offensive against the Franks began in earnest.

A path of destruction

For the next three years, Sultan Baybars prosecuted a brutal campaign of conquest and devastation, waging war on a scale not witnessed since the days of Hattin in 1187. To provide a formal justification for his attack, the sultan accused the Franks of encouraging the recent Mongol invasion of Mamluk territory to the north. Then, in early 1265, he initiated his own assault. In the past, Baybars’ first objective might have been to confront the Frankish field army, but now only a tattered remnant of this force remained. The sultan thus was free to begin the task of eliminating Latin settlements relatively unhindered.

In February the Mamluk host made camp in the woods near the fortified coastal town of Arsuf. Baybars had a massive tent erected next to the royal pavilion, within which five trebuchets were reassembled in secret. With the siege train prepared, the army marched on the Latin port of Caesarea on 27 February. Appearing suddenly and unheralded, the Muslims quickly secured control of the lower town, while the Christian populace retreated into the citadel–one of those recently refortified with the aid of King Louis IX. The sultan deployed his trebuchets, commencing heavy bombardment with stones and Greek fire, while a siege tower was raised, upon which he himself fought. By 5 March, the battered defenders had taken flight in a number of ships sent from Acre, abandoning Caesarea, and Baybars ordered the town and citadel to be razed to the ground.

Again, without announcing his target, the sultan moved south on 19 March and laid siege to Arsuf, which by this date was encircled by a major moat and possessed a sturdy keep. At first, Mamluk units under the direction of Qalawun tried to create a path to Arsuf’s walls by filling sections of its moat with vast quantities of wood (felled from local forests), but the defenders managed to burn these piles of timber during the night. After this initial setback, Baybars subjected the town to an incessant aerial barrage, and the garrison eventually capitulated on 30 April 1265 and was taken captive. In the face of this terrifying offensive, the hopelessly outnumbered Franks based in Acre were all but impotent. Even when the nominal ruler of the kingdom of Jerusalem, Hugh of Lusignan, arrived from Cyprus on 23 April with a small party of reinforcements, no move was made to counter the Mamluk invasion. In early May Baybars instructed his troops to demolish Arsuf, and, in triumph, led his Christian prisoners back to Egypt, forcing them to enter Cairo with broken crosses hung around their necks. That summer, the sultan wrote to inform Manfred of Sicily of these successes. In a stark demonstration of the casual disregard for Outremer’s future now prevalent in some western circles, Manfred responded by sending congratulatory gifts to Egypt. Others, including the papacy, began to consider action upon hearing of the Mamluk aggression.
