In page Bitola:

"

During the battle of Bitola in 1015 between a Bulgarian army under the command of the voivode Ivats and a Byzantine army led by the strategos George Gonitsiates, the Bulgarians were victorious and the Byzantine Emperor Basil II had to retreat from the Bulgarian capital Ohrid, whose outer walls were by that time already breached by the Bulgarians. Afterwards Ivan Vladislav moved the capital from Ohrid to Bitola, where he re-erected the fortress. However, the Bulgarian victory only postponed the fall of Bulgaria to Byzantine rule in 1018.[citation needed]
