The lord had fiery arrows loosed to ignite the grass and trap Yamato Takeru in the field so that he would burn to death.
Desperately, Yamato Takeru used the Ame-no-Murakumo-no-Tsurugi to cut back the grass and remove fuel from the fire, but in doing so, he discovered that the sword enabled him to control the wind and cause it to move in the direction of his swing.
