Mitsuhide, who was irritated by the prolonged battle, ended the tact of holding the castle by promising to save Hideharu and Hidenao under the condition that Mitsuhide would give his own mother (this could have been his aunt who brought him up) as a hostage to Hideharu and Hideharu and Hidenao would surrender and open the castle.
