Siege and Aftermath
The year before, Eucratides had usurped the power in Greco-Bactria while one of its rulers, Demetrius II, was conquering parts of northern India. Demetrius then made his way back into Bactria and besieged Eucratides. at the site of Eucratideia. Demetrius had an army supposedly numbering 60,000 troops, although this is unlikely.
