In preparation for an ambush of the Mongol invaders in 1288, general Tran Hung Dao (also called Tran Quoc Tuan) had hard wood stakes hidden in the grotto and planted in the bed of the Bach Dang River to cut off the retreat of the enemy. Earlier in 1287, the grotto had seved as a shelter for general Tran Khanh Du’s troop lying in ambush awaiting the food supply fleet of the Mongols.
