(some 60 km from the city), as well as a direct assault on Galata. This was a large-scale affair, supervised personally by Michael from a conspicuous elevated place, with siege engines and attempts at undermining the wall. Galata however held due to the determined resistance of its inhabitants and the reinforcements shipped over from the city in rowboats. In the face of this, and worried by news of imminent relief for the besieged, Michael lifted the siege.Macrides (2007), p. 368 The difference in the two accounts is attributed by modern scholars to Akropolites' known tendency to minimize the failures of Michael VIII. The two narratives, which both feature an attempt against Galata, are clearly referring to the same event, and the plot of Asel may indeed reflect a genuine episode of the siege which was given undue prominence by Akropolites.
