“Washington did not really outfight the British. He simply out-spied us.”
"False Intelligence Seldom remembered as a trickster, Washington was also fond of spreading disinformation. He encouraged members of the Culper Ring to exaggerate the size and strength of his forces in their conversations with British supporters. He would also spread false messages about military movements and attacks on various forts, sending them via regular post to ensure that they would be intercepted. He also turned to less-formal networks for intelligence-gathering, frequently relying on scouts to collect and convey information."
