This man has enjoyed a reputation resembling something of a secular sainthood, yet historians disagree as to what his greatest blunder was. Here is one view:
George Washington’s largest blunder was surely his signing a surrender document with the French at Ft. Necessity that acknowledged the assassination of French officers by Washington and his Indian Allies. That was the justification for the French to start a world-wide war.
Washington’s conduct during the Battle of Long Island was incredibly risky and the only thing that saved the Americans from annihilation was the lack of action by the British commanders.
He also spent most of his life in debt to the British as his tobacco crops experienced numerous failures. Historians do agree that one of his great virtues was the ability to learn from his mistakes
