The Fighting 69th (1940) is an American war film starring James Cagney, Pat O'Brien, and George Brent. The plot is based upon the actual exploits of New York's 69th Infantry Regiment during the First World War. The regiment was first given that nickname by opposing General Robert E. Lee during the Civil War.

The plot centers on misfit Jerry Plunkett, played by Cagney, and his inability to fit into the unit due to a mixture of bravado and cowardice. O'Brien plays Father Francis P. Duffy, a military chaplain who attempts to reform Plunkett. "Wild Bill" Donovan, played by Brent, is the regimental commander, who ultimately orders Plunkett to be court-martialed. One of the characters portrayed in this film is Sgt. Joyce Kilmer, the poet. Alan Hale, Sr. plays Sgt Wynn, who loses both his brothers due to Cagney's blunders.

While Jerry Plunkett was a fictional character, Father Duffy, Colonel Donovan and Joyce Kilmer were all part of the actual regiment.

"The Fighting 69th" is a First World War regiment of mostly New York-Irish soldiers. Amongst a cocky crew, perhaps the cockiest is Jerry Plunkett, a scrappy fellow who looks out only for himself. The officers and non-coms of the regiment do their best to instill discipline in Plunkett, and the chaplain, Father Duffy, tries to make Plunkett see the greater good, all to no avail. Behind the lines or in the trenches, Plunkett acts selfishly and cowardly, eventually costing the lives of many of his fellow soldiers. A final act of cowardice leads to terrible consequences, but Plunkett sees in them a chance to redeem himself...if only he can. Written by Jim Beaver
