Have you ever seen "The Horse Soldiers" I think it was called (not the Civil War John Wayne) about Anzac mounted infantry charging Turkish guns? I have only seen it once, would like to see it again.
I always visit this thread too late, a few of those movies above I have never heard of before and would like to see.
I'll have to keep my eye open for that one as the only Horse Soldiers I have seen is the John Wayne version.
It is called "The Light Horsemen"
"Set in 1917 during the British campaign in Palestine, this is the true and epic story of the
800 young Australian horsemen who obey the seemingly impossible order to gallop their
horses across 3 miles of open desert into shell-bursts and deadly machine-gun crossfire."
