Generals Washington, Grant and Patton would disagree.
No way to prove it, but strongly suspect that both Grant and Patton understood that Lee was their better.
Would they? I wouldn't want to speak ill of any of those in this group. But arm chair warriors arguing over who was the best General is almost always a completely pointless and futile exercise. There are a large number of men who were the very highest caliber leaders many whom gave their lives in defense of our Republic. The vast majority are now almost completely forgotten
How many people these days even know the name of General Rose the leader of the 3rd Armored Division during WWII and the the highest-ranking American killed by the Nazis? Most people these days believe that Patton was the leader of Spearhead, the 3rd Armored Division during WWII. That is what a full length movie and a gravelly voiced portrayal by a fine actor accomplishes. Patton gets credit for everything.
That said there are few who would argue on behalf of the woke bunch of idiots who make up our current top brass. In July of 2017 President Trump famously called the group to their faces a ‘Bunch of Dopes and Babies’ who were ‘all losers’. He told them, “You don't know how to win anymore. I want to win. We don't win any wars anymore. We spend $7 trillion, everybody else got the oil and we're not winning anymore.” After this accurate assessment, almost the entire group of thin skinned oversensitive babies devoted themselves to stabbing President Trump in the back for the rest of his time in office.
It is completely irresponsible to tear down monuments erected many years ago dedicated to any of the great men who fought valiantly to shape our country.
