Nichols (Sir Laurence Olivier) makes a comment to Roberts (Adolphe Menjou) along the lines of "The Old Guard dies, but never surrenders its shower".

Cambronne said afterwards that his reply was, "Merde," (sh*t). For years afterwards, the word "merde" was referred to by the French as "le mot de Cambronne" (Cambronne's word).
