It’s so funny how the American Revolution is virtually the same. Even in your description.
Washington doesn’t get the credit he deserves. His situation was MUCH worse than the noted “rag-tag” Confederate army. He dealt with much worse, including trying to ensure Congress had a say in how the war was run so he was not a military dictator. Once Washington threw off that concern his natural genius becomes even more apparent. And it’s not all due to the French, despite constant refrains that it was. They hardly did anything besides supply. Washington had to hold it together with almost nothing, and wear them down also. He did so.
I agree that historian short change Washington’s military abilities. One key thing he had was the ability to learn from mistakes !
I guess I rate him a little below Lee only because he did not skillfully wield large armies as Lee did (Washington didn't have any!). I read a 4-volume biography of Washington about a year ago and was kind of surprised how much less fighting occurred in the Revolution as opposed to the Civil War. However, Washington was the man for the job. His inspirational qualities as a leader held the Continental Army together. I think he would have been bitterly disappointed in Lee for deserting the cause of the Union.
