This forced Abdal-Latif Mirza's hand to take action which he did by attacking Mirza Saleh who then escaped to Herat. On this Ala al-Dawla Mirza marched from Herat with his army and besieged Balkh in the winter of 1447 C.E. Abdal-Latif Mirza sent a letter to his father Ulugh Beg for reinforcements. In response Ulugh Beg sent an envoy to Ala al-Dawla Mirza to admonish him and to let him know to address his grievances to Samarkand in the future rather than go to war.
