'' showing Romanos III encamped near Azaz with his army In March 1030, Romanos departed
Constantinople, leading in person the campaign against Aleppo. According to Psellos, Romanos was so confident of his success that he prepared special crowns for his triumph to come, and staged a grandiose entry into Antioch, which he reached on 20 July. Nasr, learning of the Byzantines' approach, sent envoys, led by his cousin
Muqallid ibn Kamil, and offered to recognize Byzantine suzerainty and to restart the payment of tribute. According to Psellos, Nasr's envoys "declared they had not wanted this war, nor had they given him [Romanos] any pretext for it", but "seeing that he was now adopting a policy of threats, and since he insisted in parading his strength" they would prepare for war should Romanos not change direction. Romanos was encouraged by the
Jarrahid chieftain of the
Banu Tayy tribe,
Hassan ibn Mufarrij, to continue his march; the Jarrahid hoped to use the Emperor's assistance in regaining the pasture territories in Palestine that the Tayy had been forced to give up after their defeat alongside the Mirdasids at al-Uqhuwanah. According to Skylitzes, the Emperor's own generals counselled him to accept Nasr's offer so as to avoid the hazards of campaigning in the arid Syrian desert in the summer, especially as their troops were unaccustomed to such conditions and were encumbered by their heavy armour. This is also reflected in the opinions of modern scholars, who point out that the Kilab, accustomed to the swift movement of the
Bedouin nomads, had a distinct advantage over the heavier, slower-moving Byzantine armies. Persuaded that the expedition against Aleppo would be easily successful, the Emperor rejected his generals' advice: he detained Muqallid and led his army towards Azaz (Azazion in Greek) on 27 July. At the same time, he sent Hassan a spear as a sign of his authority, and ordered him to stand by with his men and await his arrival. Psellos commented on this decision that Romanos "thought war was decided by the big battalions, and it was on the big battalions that he relied". The Byzantine army encamped on a barren plain in the vicinity of Azaz and dug a deep defensive trench around their position. Meanwhile, Nasr and Thimal made their own preparations; they evacuated their families from Aleppo, mobilized the warriors of Kilab and other Bedouin tribes, particularly the
Banu Numayr, and, under the call for
jihad (holy war), the Muslim inhabitants of Aleppo and its countryside. The majority of the mobilized forces were commanded by Thimal, who safeguarded Aleppo and its
citadel. The remaining troops, composed entirely of lightly-armoured Kilabi and Numayri horsemen, were led by Nasr, who set out to confront the Byzantine force. Arabic accounts of Nasr's troops vary: the Aleppine chroniclers Ibn al-Adim and
al-Azimi (d. 1160s) recorded 923 horsemen,
Ibn Abi'l-Dam (d. 1244) counted 700, the Egyptian
al-Maqrizi (d. 1442) recorded 2,000, while
Ibn al-Jawzi (d. 1200) counted 100 horsemen and 1,000 infantry. In Zakkar's view, the latter figure is highly questionable as nearly all sources hold that Nasr's force was made up entirely of cavalry. The Byzantine army is estimated by modern scholars at some 20,000 men and contained many foreign
mercenaries. In contrast to their precise counts of Nasr's forces, the Arabic chroniclers record the fantastical figures of 300,000 or 600,000 Byzantine troops. ==Battle==
