Azuchi Castle
According to a record kept by Oda clan, Mitsuhide offered his mother as a hostage to allow to Hideharu surrender with dignity. Hideharu complied knowing that he could not hold out indefinitely. However, after arriving at Azuchi Castle to offer an apology, Hideharu was executed by Nobunaga. His troops in Yakami Castle, hearing that Hideharu had been executed, killed Mitsuhide's mother. This incident strained the relationship between Nobunaga and Mitsuhide, eventually culminating in Mitsuhide killing Nobunaga at Honnō-ji in 1582. However, there is little evidence that these events actually happened and it is unlikely Mitsuhide would offer such questionable truce. After Hideharu's death, no one rose to hold together the Hatano clan and it disappeared completely.
