The reinforcements he expected from the Turcoman tribes failed to materialize, and morale was low, but Burhan al-Din remained in place, and even defeated a detachment sent by Bayezid to win over the tribes.[15] Although likely true, this victory may have been exaggerated by Ibn Ardashir, for Manuel reports that the Ottoman army continued its advance deep into the central Anatolian plateau, advancing beyond Ankara. According to Manuel, Bayezid was satisfied with his progress, and with the Byzantines' contributions, promising to reward them.[17]
