Karl XII.
Pretty beast Swedish king who pretty much beat 3 Great Powers on his own.
Sadly, like most of our more prominent kings, he manages to stupidly get himself killed in battle.
Gustav Adolf, looking at you here.
They were just Vikings ^.^
Anyway a lot of great gen, had only luck, that they didnt die on the battlefield. For me the best one is gen Lee.
Gettysburg, his biggest fault, he didnt blame tactic or soldiers only himself. Also, Union lost more men in battle against smaller army:P
