"Concerning the night assault of Lord Asano's ronin, the fact that they did not commit seppuku at the Sengakuji was an error, for there was a long delay between the time their lord was struck down and the time when they struck down the enemy. If Lord Kira had died of illness within that period, it would have been extremely regrettable."
—Tsunetomo Yamamoto in The Hagakure, trans. William Scott Wilson
