Despite some probing attacks, the Ottoman fleet under Baltoghlu could not enter the Golden Horn due to the chain across the entrance. Although one of the fleet's main tasks was to prevent any foreign ships from entering the Golden Horn, on 20 April, a small flotilla of four Christian ships managed to get in after some heavy fighting, an event which strengthened the morale of the defenders and caused embarrassment to the Sultan. Baltoghlu was most likely injured in the eye during the skirmish. Mehmed stripped Baltoghlu of his wealth and property and gave it to the janissaries and ordered him to be whipped 100 times.^[12]
