Well, you might want to read about what acctually happened at Balaclava. It's an interesting story, more then a poem or a movie........
Oh, I have read a bit. Classic example of what happens when a commission is bought. Money cannot buy leadership abilty or experience. Also shows what happens when ego and blind obedience collide. Look at the War Between the States, many times an individual that couldn't get into the military raised a volunteer unit and suddenly was a combat commander.
Incidentially, from what I have read, the majority of the casualties were inflicted after the force abandoned the cannons and headed back to their lines. Misunderstanding orders and not being able to capitalize on unexpected victories often leads to defeat.
