It revealed from this letter that Muneshige borrowed some money from his vassal for the travelling expenses for his mother to go to the Tokugawa family as a hostage. He mentioned in the letter that he would repay the money until the next autumn even if he would be transferred from Yanagawa to another domain. This indicates that he was prepared for transference of his fief but never thought to be deprived of his fief and position at that time.
