Context paragraphs:
Handy Writers' Colony: The Handy Writers' Colony, often called simply the Handy Colony or The Colony, was a writers' colony located in Marshall, Illinois, which operated from 1950–1964.  The Handy Colony was founded in 1950 by Lowney Turner Handy and her husband, Harry Handy, along with Lowney's student (and then-lover), best-selling novelist James Jones.  Lowney Handy was the Colony's quirky teacher and mentor, with financial support coming from her husband and Jones, particularly after the sale of Jones' first novel, "From Here to Eternity".  A unique aspect of Handy's approach was to have her students spend many hours simply copying, by hand or typewriter, materials from authors whose work she admired.

It portrays soldiers of C Company, 1st Battalion, 27th Infantry Regiment, 25th Infantry Division, played by Sean Penn, Jim Caviezel, Nick Nolte, Elias Koteas and Ben Chaplin.  Although the title may seem to refer to a line from Rudyard Kipling's poem "Tommy", from "Barrack-Room Ballads", in which he calls foot soldiers "the thin red line of heroes", referring to the stand of the 93rd Regiment in the Battle of Balaclava of the Crimean War, it is in reality a quote from Jones's book which reads, "they discover the thin red line that divides the sane from the mad... and the living from the dead..."
