Moko Shurai Ekotoba

A larger image with other Mongol Auxiliary infantrymen
Mongol warriors depicted on a Japanese emakimono. The Moko Shurai Ekotoba was created by Takezaki Suenaga to press his claims for reward after the war against the Mongols.
Source: A site with the 13th century original and later versions. Sections 6, 7 & 8 of the 'Guided View' tab shows that the 3 Mongol soldiers & the bursting shell were later additions to the 13th century scroll.
Other illustrations of North Chinese and Manchurian troops also show helmets with feathers. The Song Chinese had wings on their helmets. The helmet and clothes are characteristic of Mongols, Khitan & Turks, so the 3 figures may be dismounted cavalry. Ceramic shells called Zhen tian lei (thunder crash bombs) in Chinese, or tetsuhau in Japanese, were discovered on the sea bottom. Tests indicated that the had held gunpowder.
