. With Theodore gone, Heraclius appointed Trithyrius to take lead as the commander of his brother's army. In 635, however, things were beginning to take a serious toll when the Byzantine armies failed considerably at other battles. This partly due to financial setbacks and the Byzantine empire failing to provide salaries for the troops, Trithyrius found himself in another role. For most times, Trithyrius's role with the army served as a constant reassurance. A certain lassitude had filled the air and Heraclius had to disband many regiments for economy's sake.
