 The plot stretched longer than a year, and Tamekage's patience grew thin.It is believed that Tamekage "arranged" for correspondence between himself and the brothers to be discovered by an ally of Yoshimune, which would lead to their executions, perhaps a quicker route to weakening the Jinbo than the possibly ill-conceived plot with Nagakiyo.The Jinbo brothers were executed, and the Jinbo weakened.
