A clay tablet that says this: From Wiki on Nebu.
Following the pacification of Tyre, Nebuchadnezzar turned again to Egypt. A clay tablet,[7] now in the British Museum, states: "In the 37th year of Nebuchadnezzar, king of the country of Babylon,
he went to Mitzraim (Egypt) to wage war. Amasis, king of Egypt, collected [his army], and marched and spread abroad." Having completed the subjugation of Phoenicia, and a campaign against Egypt, Nebuchadnezzar set himself to rebuild and adorn the city of Babylon, and constructed canals, aqueducts, temples and reservoirs.

Here's what the Jewish Encyclopedia says on Neb.
Ihe king and his sons were brought before Nebuchadnezzar at Riblah; the sons were slain, and the king's eyes bored out; and he was carried in chains to Babylon. Nebuchadnezzar caused Jerusalem to be destroyed, and the sacred vessels of the Temple to be carried to Babylon. He placed Gedaliah in authority over the Jews who remained in the land. In the twenty-third year of his reign Nebuchadnezzar's captain of the guard carried away 745 Jews, who had been gathered from those scattered through the land. Nebuchadnezzar entered Egypt also (Jer. xlvi. 13-26; Ezek. xxix. 2-20),
according to his own inscriptions about 567, and dealt a severe blow to its supremacy and power.
