I don't think he was that different from today's soldiers, and there certainly was no unseemly shuffle to get in the back rank! They had huge pride in their achievements! They were professionals, and far from facing certain death, they reckoned they were being led to certain victory. Death rates in battle were not that different from, say, the rates in an infantry platoon of the Second World War. It may seem ludicrous to us that they wore bright colours and stood in close rank, but that's a product of the inadequate weaponry they faced and, as soon as those weapons became more accurate (and death more certain) the tactics changed. There was war-weariness, and Sharpe shows it in the books, and only an idiot would not have felt fear in battle, but that is a constant in history. Interestingly it is the French, with their conscript army, who are forced into using columns, from which it's hard to escape. Why didn't they crack? Well some did. But most kept going and, I'm certain, that had nothing to do with King and Country, and everything to do with not letting down your mates . . . how often have we heard of the bonds between men in battle? Tighter than family, and that, I think, is what inspired them and gave them the necessary courage . . . . which was bolstered by discipline, training and a genuine confidence (in Wellington's army, at least) in the quality of the leadership being provided.
