Chief Wallace Boden has long been the cornerstone of Firehouse 51,

but now fans must adjust to a new leadership dynamic as he bids

farewell to Chicago Fire. After 12 seasons, actor Eamonn Walker

has officially exited the series, leaving fans to wonder why Boden left and if this marks the end of his story.

Chicago Fire, produced by Dick Wolf, first premiered in 2012 and follows the personal and professional lives of firefighters, paramedics, and rescue personnel at the fictional Firehouse 51. As the flagship of the One Chicago franchise, which includes Chicago P.D., Chicago Med, and the now-canceled Chicago Justice, the series has captivated audiences with its intense drama and character development.

What Happened to Chief Wallace Boden on Chicago Fire?

Boden, portrayed by Eamonn Walker since the series’ inception, has served as the Deputy District Chief of District 4 and the former Battalion Chief of Firehouse 51. After over 40 years with the Chicago Fire Department, he has become a beloved figure and one of the last original characters on the show, alongside Kelly Severide (Taylor Kinney), Christopher Herrmann (David Eigenberg), Joe Cruz (Joe Minoso), and Randall “Mouch” McHolland (Christian Stolte).

In May 2024, it was announced that Walker would be leaving Chicago Fire after his last full-time appearance in the Season 12 finale, titled “Never Say Goodbye.” In this episode, Boden accepts a new position as Deputy Fire Commissioner for the Chicago Fire Department, effectively stepping down from his role at Firehouse 51 and appointing Senior Firefighter Christopher Herrmann as the new captain.

Boden’s exit had been anticipated throughout Season 12, especially after he learned about Deputy Fire Commissioner Gloria Hill’s (J. Nicole Brooks) upcoming retirement and discovered that his name was on the shortlist for her position. Complications arose when Paramedic Field Chief Robinson (Laura Allen) actively tried to sabotage Boden’s chances, leading to a tense series of events that ultimately ended with him accepting the new role.

Why Did Eamonn Walker Leave Chicago Fire?

While Boden’s departure marked a significant change for the series, it aligns with a trend of character exits in Season 12. Alongside Walker, other characters such as Sylvie Brett (Kara Killmer), Blake Gallo (Alberto Rosende), and Derrick Gibson (Rome Flynn) also departed. However, Walker is expected to return in a recurring role, allowing for a potential continuation of Boden’s storyline.

Showrunner Andrea Newman addressed the wave of exits, citing the need for freshness and evolving dynamics in a show that has been running for over a decade. “Longevity is really just part of it,” Newman explained. “You want new characters and new dynamics. Twelve years is a long time, and nobody expects to stay in one role that long in television.”

Newman also hinted that Boden’s personal life, particularly his relationship with his stepson James, played a role in his decision to step back from Firehouse 51. As Boden navigated personal and professional changes, the finale promised to reveal how his leadership would be affected by these shifts.
