Who are the great generals?

[William F. Owen]

Every single one of them spoke English, and three out five from the UK and Ireland. Four out of five served in the last century. This list seems to be rather biased.

Sure it's biased. I make no excuse. You might also note they were all on the winning side!
They are the guys that work for me, in terms of what can be learnt. Comparing Generals is essentially a fashion statement. It says far more about me, than it does the Generals.

The useful element here is finding out WHY folks think certain generals are great, not WHO!

Petraeus: Petraeus inherited a lost cause in what has to be one of the most complex civil wars in history and implemented COIN operations that drastically reduced casualties and violence. All this while public support was on the decline and in the face of a hostile government.

....and I disagree with nearly every single item of that description - as would a few other denizens of this board
