The Byzantines observed strange and ominous signs in the days leading up to the final Ottoman assault on the city. On 22 May, there was [[May 1453 lunar eclipse|a lunar eclipse]] for three hours, harkening to a prophecy that Constantinople would fall when the moon was on [[Lunar phase|wane]].<!-- Verbatim from the source?
 --> In order to encourage the defenders, Constantine commanded that the icon of [[Mary, mother of Jesus|Mary]], the city's protector, was to be carried in a procession through the streets. The procession was abandoned when the icon slipped from its frame and the weather turned to rain and hail. Carrying out the procession on the next day was impossible as the city became engulfed in a thick fog.{{Sfn|Nicol|1992|p=|pp=66–67}}

On 26 May, the Ottomans held a war council. Çandarlı Halil Pasha, who believed western military aid to the city was imminent, counseled Mehmed to compromise with the Byzantines and withdraw whereas [[Zagan Pasha]], a military officer, urged the sultan to push on and pointed out that [[Alexander the Great]] had conquered almost the entire known world when he was young. Perhaps knowing that they would support a final assault, Mehmed ordered Zagan to tour the camp and gather the opinions of the soldiers.{{Sfn|Nicolle|Haldon|Turnbull|2007|p=229}} On the evening of 26 May, the dome of the Hagia Sophia was lit up by a strange and mysterious light phenomenon, also spotted by the Ottomans from their camp outside the city. The Ottomans saw it as a great omen for their victory and the Byzantines saw it as a sign of impending doom. 28 May was calm, as Mehmed had ordered a day of rest before his final assault. The citizens who had not been put to work on repairing the crumbling walls or manning them prayed in the streets. On Constantine's orders, icons and relics from all the monasteries and churches in the city were carried along the walls. Both Catholics and Orthodox defenders joined in prayers and hymns and Constantine led the procession himself.{{Sfn|Nicol|1992|p=|pp=66–67}} Giustiniani sent word to Loukas Notaras to request that Notaras' artillery be brought to defend the land walls, which Notaras refused. Giustiniani accused Notaras of treachery and they almost fought each other before Constantine intervened.{{Sfn|Nicolle|Haldon|Turnbull|2007|p=229}}

In the evening, the crowds moved to the [[Hagia Sophia]], with Orthodox and Catholic Christians joining and praying, the fear of impending doom having done more to unite them than the councils ever could. Cardinal Isidore was in attendance, as was Emperor Constantine. Constantine prayed and asked for forgiveness and remission of his sins from all the bishops there before he [[Eucharist|received communion]] at the church's altar. The emperor then left the church, going to the imperial palace and asking his household there for forgiveness and saying farewell to them before again disappearing into the night, going to make a final inspection of the soldiers manning the city walls.{{Sfn|Nicol|1992|p=|pp=67–69}}

Without warning, the Ottomans began their final assault in the early hours of 29 May.{{Sfn|Nicol|1992|p=|pp=69–70}} The service in the Hagia Sophia was interrupted, with fighting-age men rushing to the walls to defend the city and the other men and women helping the parts of the army stationed within the city.{{Sfn|Carr|2015|p=256}} Waves of Mehmed's troops charged at Constantinople's land walls, hammering at the weakest section for more than two hours. Despite the relentless attack, the defense, led by Giustiniani and supported by Constantine, held firm.{{Sfn|Nicol|1992|p=|pp=69–70}} Unbeknownst to anyone, after six hours of fighting, just before sunrise,{{Sfn|Nicol|1992|p=|pp=69–70}} Giustiniani was mortally wounded.{{Sfn|Nicolle|Haldon|Turnbull|2007|p=233}} Constantine begged Giustiniani to stay and continue fighting,{{Sfn|Nicol|1992|p=|pp=69–70}} allegedly saying:

{{blockquote|quote=My brother, fight bravely. Do not forsake us in your distress. The salvation of the City depends on you. Return to your post. Where are you going?{{sfn|Nicolle|Haldon|Turnbull|2007|p=233}}|title=|source=}}

Giustiniani was too weak, however, and his bodyguards carried him to the harbor and escaped the city on a Genoese ship. The Genoese troops wavered when they saw their commander leave them, and though the Byzantine defenders fought on, the Ottomans soon gained control of both the outer and inner walls. About fifty Ottoman soldiers made it through one of the gates, the ''[[Kerkoporta]]'', and were the first of the enemy to enter Constantinople; it had been left unlocked and ajar by a Venetian party the night before. Ascending up the tower above the ''Kerkoporta'', they managed to raise an Ottoman flag above the wall. The Ottomans stormed through the wall and many of the defenders panicked with no means of escape. Constantinople had fallen.{{Sfn|Nicol|1992|p=|pp=69–70}} Giustiniani died of his wounds on his way home. Loukas Notaras was initially captured alive before being executed shortly after. Cardinal Isidore disguised himself as a slave and escaped across the Golden Horn to Galata. Orhan, Mehmed's cousin, disguised himself as a monk in an attempt to escape, but was identified and killed.{{Sfn|Nicolle|Haldon|Turnbull|2007|p=234}}
