Ignorance? Read about him, like you did Rommel. There is much there to this phenomenal leader and human being. Clearly evident that Lee was arrived at by Davis quite late— too late really. And Lee had courtesy toward Davis but not his leadership decisions.
Rommel was implicated in the plot on Hitler, hence his “suicide”. Rommel was a superior trained fighting soldier. And Hitler... a lunatic wannabe artist.
My dad fought in the pacific during WW2, and he hated the ‘Japs’, but he respected Admiral Isoroku Yamamoto. Yamamoto did not want war with the US, but he was loyal to his Emperor. Lee and Yamamoto were both in wars that neither one wanted.
