Mongol ships, drawn from Korea and the remnants of the Sung navy, were far superior to the primitive Japanese boats. They were capable of bringing thousands of troops over several hundred miles of ocean to Japan. Nevertheless, supplies ran low, and contributed to the Mongol defeat. Ships have been excavated from Takashima, but because they were so light―most of their provisions having been exhausted―they did not sink deeply into the mud. Hence, little of their wooden structures survive. Anchor stones remain, however. Some intact wooden anchors have been excavated, while other anchor stones grace the compounds of local shrines, such as those depicted here.
