I have found a good image of armoured cavalrymen attacking a fortress, from Semireçye in Central Asia, 9th-10th century, State Hermitage Museum, St. Petersburg, S-46 (http://www.warfare.altervista.org/6-10/Plate-Semirecye-St_Petersburg.htm)
(http://i1368.photobucket.com/albums/ag197/druzhina345/Ancient/th/Plate-Semirecye-St_Petersburg_th.jpg)
It is probably the siege of Jericho even though the man holding an ark and the seven trumpeters are on the lower lover of the fortification.
There are three standards shown, various maces, one perhaps an animals head, the bowcases are for unstrung bows, the quivers for arrows point upwards. The helmets have knobs or points on top and a hint of a nasal similar to illustrations of helmets from the Tarim basin (http://www.warfare.altervista.org/6-10/Tarim-helmets.htm).
