When the local commander, Lt. Col. Jameson, heard about the situation, he immediately reported it to his commanding officer: Benedict Arnold. By the time events were reported to General Washington, Arnold had
escaped. He boarded the Vulture and was taken to British lines.
Concerned about the safety of his wife, Benedict Arnold wrote to General Washington. Recognizing how his actions would appear, he tried to explain he did it for the love of country:
I have ever acted from a principle of love to my country since the commencement of the present unhappy contest between Great Britain and the Colonies.
With wounded pride still part of his psyche, Arnold raised the issue of “the ingratitude of my country” toward himself. He begged Washington, however, not to let “the mistaken vengeance of my country” fall on Mrs. Arnold when “it ought to fall only on me.”
He wanted safe passage for Peggy. Unaware of her role in the treason, the Commander-in-Chief had the necessary paperwork prepared. Following specific instructions, Mrs. Arnold joined her husband. One week later, the former American hero wrote to Washington, thanking him for his kindness toward Peggy.
In the meantime, however, John Andre faced a different reaction from Washington.
