我在网络上找不太到"西方四大名将"这个称号的来源，
但是我找到拿破仑的一句话(下面是英文版的其中一种翻译) :
Read over and over again the campaigns of Alexander, Hannibal, Caesar,
Gustavus, Turenne, Eugene, and Frederic. Make them your models. This is the
only way to become a great general and to master the secrets of the art of
war. With your own genius enlightened by this study, you will reject all
maxims opposed to those of these great commanders.
里面提到的七位将领是亚历山大、汉尼拔、凯撒、古斯塔夫、蒂雷纳、欧根、腓特烈
除了拿破仑本人之外，西方四大名将常见版本的另外三人都名列其中，
可见至少他们确实是拿皇钦点的顶尖将帅
这句话我也有找到中文版本，但是后半句和英文版不同...
