There is the famous boast attributed to him by Horace Walpole.

In a despatch which Washington sent back to the Governor after the little skirmish in which Jumonville was killed, Washington said: "'I heard the bullets whistle, and, believe me, there is something charming in the sound.' On hearing of this the King said sensibly, 'he would not say so if he had been used to hear many.'" This reply of George II deserves to be recorded if only because it is one of the few feeble witticisms credited to the Hanoverian Kings.
Years afterward, Washington declared that he did not remember ever having referred to the charm of listening to whistling bullets.
Perhaps he never said it; perhaps he forgot.

He was only twenty-two at the time of the Great Meadows campaign.

No doubt he was as well aware as was Governor Dinwiddie, and other Virginians, that he was the best equipped man on the expedition, experienced in actual fighting, and this, added to his qualifications as a woodsman, had given him a real zest for battle.

In their discussion over the campfire, he and his fellow officers must inevitably have criticized the conduct of the expedition, and it may well be that Washington sometimes insisted that if his advice were followed things would go better.
