Charge Of The Light Brigade: Britain's most famous Military Disaster

We have our (when Texas let's us borrow it) Alamo. The Brits have the "Charge of the Light Brigade".

Remember having to remember and recite the poem, never could recite the whole thing.

"Cardigan knew it was a suicidal charge", hmmm@@. I'm not a die-hard lover of history, but there has to be a back story as to why in their leadership confusion, that a Commander would knowingly sacrifice them all including himself.
