May I butt in. Warhorse is a book,and I think a musical,concerning the life of a horse during the 1914-1918 war.It has been made into a film to be released in Dec.
A real tear jerker if ever there was one.
Thanks TJ for responding to Sylvia's post(I had closed down for the night when the question came in) Yes, the musical Warhorse is based on the book and is an immensely moving story of the bond between a WW1 soldier and his horse. The stage version is at the New London Theatre until at least October 2012.
