Hi Steve,
I'm not sure of the worst order ever drafted - however Raglan's (4th Order, was it?) was vague, Airey was ambiguous, Lord 'Look-On' hated the 'Noble Yachtsman', who in turn despised 'That Indian Officer', Cathcart was having breakfast and Scarlett probably short sighted.....
It was the perfect storm of military incompetence.....
However the Old Rag, new what he meant......and where the cavalry was sposed to go......
Hay ho... c'est le guerre.....
