How did the japanese forces defeat the invading mongols in the 13th century?

Around nightfall, a severe storm caused the Mongol ship captains to suggest that the land force re-embark on the sailing vessels in order to avoid the risk of being marooned on Japanese soil. By daybreak, only a few ships had not set out to sea. Those that had were destroyed by the storm. Some accounts offer casualty reports that suggest 200 Mongol ships were lost. However, Japanese small boats were  more maneuverable than Mongol ships, and the Japanese were able to board the remaining Mongol ships.
