One has described it well--Florentius of Buda.

I can only repeat a few of his words:--"On the appointed day, Hunyadi, with two hundred vessels, attacked the Turkish flotilla in front, whilst Szilagy, with forty vessels, filled with the men of Belgrade, assailed it in the rear; striving for the same object, they sunk many of the Turkish vessels, captured seventy-four, burnt many, and utterly annihilated the whole fleet.

After this victory, Hunyadi, with his army, entered Belgrade, to the great joy of the Magyars.

But though the force of Mahomed upon the water was destroyed, that upon the land remained entire; and with this, during six days and nights, he attacked the city without intermission, destroying its walls in many parts.

His last and most desperate assault was made on the 21st day of July.
