However, both Howe and Washington made many mistakes during the Battle of Brandywine. Washington left his right flank open, allowing the British to flank the American defenses. He came very close to being captured, saved from that fate by Howe's cautious nature, which caused him to hesitate for two hours after flanking Washington's army. This timeline will explore what would have happened had Howe committed to his attack immediately, rather than waiting for two hours. September 11, 1777 will demonstrate that one minor edit to history can have significant ramifications over the course of history itself.
