Hail & Farewell is the 20th episode of NCIS Season 16 and also the 374th episode of the entire NCIS series.


NCIS investigates the murder of a Marine Major believed to have been killed in the 9/11 attack on the Pentagon after human remains are discovered at a construction site with a personal history with the victim soon driving Gibbs to solve her crime.

Major Events

  • Gibbs is revealed to have been engaged to Major Wallace at some point before her death, an engagement he ultimately broke off due to feeling it was better off for her if she didn't marry him in the long run.
    • Gibbs is also revealed to have felt guilty since he did not answer the phone in what was ultimately her last call to him.
  • McGee invokes Rule 10 and removes Gibbs from the case briefly, when his relationship becomes a focus of the case.


  • This episode shares its title with two episodes of JAG, Hail and Farewell Part 1 which was the JAG Season 8 finale episode and Hail and Farewell Part 2 which was the JAG Season 9 premiere episode.
