Hi folks,
A few decades ago (early70's) I remember seeing a WW1 film about the person who came up with mustard gas and how it finaly was introduced to the trenches. This film was not a documentary. The most striking seen was the closing segment when what looked like many hundreds of cloaked and gas masked cavalry advanced through no mans land with infantry support. I'd love to get a copy of this old TV? film on DVD. Needless to say, this has been eating at me for a long, long time.
Thanks in advance
