+    <History>Even after the fall of the Neo-Assyrian Empire, the Assyrians themselves remained active in events. Under the Achaemenids they served in their own national regiments together with the Chaldeans. Naturally, they continued to employ the siege skills that made Assyria so famous in Persian service.</History>
