On March 15, Governor Wallace replied, agreeing to a secret meeting to discuss the situation. Bonney met with Wallace in Lincoln on March 17, 1879. During the meeting and in subsequent correspondence, Wallace promised Bonney protection from his enemies and clemency if he would offer his testimony to a grand jury. [b] On March 20, Wallace wrote to Bonney, "to remove all suspicion of understanding, I think it better to put the arresting party in charge of Sheriff Kimbrell [sic] who shall be instructed to see that no violence is used". [c] Bonney responded on the same day, agreeing to testify and confirming Wallace's proposal for his arrest and detention in a local jail to assure his safety.  On March 21, Bonney let himself be captured by a posse led by Sheriff George Kimball of Lincoln County. As agreed, Bonney provided a statement about Chapman's murder and testified in court.
