2 Kings 25:1

In the ninth year ... - As the final catastrophe approaches, the historian becomes more close and exact in his dates, marking not only the year, but the month and the day, on which the siege began, no less than those on which it closed 2 Kings 25:3. From Ezekiel 24:1 we find that on the very day when the host of Nebuchadnezzar made its appearance before Jerusalem the fact was revealed to Ezekiel in Babylonia, and the fate of the city announced to him Ezekiel 24:6. The army seems to have at first spread itself over all Judaea. It fought, not only against Jerusalem, but especially against Lachish and Azekah Jeremiah 34:7, two cities of the south 2 Chronicles 11:9, which had probably been strongly garrisoned in order to maintain the communication with Egypt. This division of the Babylonian forces encouraged Hophra to put his troops in motion and advance to the relief of his Jewish allies Jeremiah 37:5. On hearing this, Nebuchadnezzar broke up from before Jerusalem and marched probably to Azekah and Lachish. The Egyptians shrank back, returned into their own country Jeremiah 37:7; Ezekiel 17:17, and took no further part in the war. Nebuchadnezzar then led back his army, and once more invested the city. (It is uncertain whether the date at the beginning of this verse refers to the first or to the second investment.)

Forts - Probably moveable towers, sometimes provided with battering-rams, which the besiegers advanced against the walls, thus bringing their fighting men on a level with their antagonists. Such towers are seen in the Assyrian sculptures.
