On February 10, 1812, Anne wrote the following in her journal:
February 10th: Captain C. returned from the United States. This was the second time my Father had sent him to make observations and judge what probability there was of a War. I remember Captain C. telling a ridiculous anecdote of the French Ambassador speaking to him at one of the President's Levees, supposing him an American, and when he was introduced as a British Officer the Frenchman turned away, as if afraid of contamination.
