An interesting question and one that demands some reflection on the recording of history as a whole. One must remember that just because something is written in a book,or several, it is not necessarily fact. Much of the info out there about the villans of history such as Nero, Vlad and Stalin are pure propaganda, and so much of the truth is lost in this.
Which group are using the works of a certain person at any one time can also be a factor. The teachings of Nietzsche, and, to a lesser extent, Darwin, were manipulated by the Nazis to sure up their own philosophies, which leds many to belive, wrongly, that they in turn were Nazis or right wing.
The perspective of the person who is writing the history is, perhaps, more important then the actual facts. For example; in my country Michael Collins is seen as a great man. A man who helped from the IRA, a man who fought the British Empire to a sandstill with a handful of rifles. A freedom fighter, a man to aspire to. A hero. However, to the British he is, was and all ways will be a terrorist. Who is right?
Anyhow, just for fun, here is mine.
Archibald Wavell. Commander of the British forces in N. Africa 1939-41(I think, cant remember) Defeated a army of 100,000's of Itallians with c40,000 men, Operation Compass. Lost out badly when the Germans came to N.Africa though. He had been order to send a good chunk of his forces to help repell the Germans in Greec, an order he disagreed with, but carried out non the less. This left him undermaned and under equiped to fight the Germans. Despite this Rommel classed him as a good General. I feel he often gets a bad run cause of Monty's suceuss not long after. However by that stage the situation in N.Africa was very diffrent.
