I saw this movie accidentally on 2/22/2004 from Cinemax. Then the story of this cavalry movie really touched me. I wondered very much how the cavalry soldiers felt when they were to be replaced with mechanized units. It must be a very difficult time for them. Because I didn't remember the title of this movie after I saw it, I had tried very hard to find out more history behind this movie. For example, I found one thesis titled¡§GREASY AUTOMATONS AND THE HORSEY SET : THE U.S. CAVALRY AND MECHANIZATION, 1928-1940", written by VINCENT J. TEDESCO III for his Master Degree at THE PENNSYLVANIA STATE UNIVERSITY, THE GRADUATE SCHOOL, COLLEGE OF THE LIBERAL ARTS in May 1995. I tried to study if this movie story was real. Eventually I searched IMDb today and got some information about this movie. I feel very happy that IMDb provides such useful data of all movies. I would appreciate very much if people can tell me any more true history of those characters in this movie.
