From Diary of the American Revolution, Vol II. Compiled by Frank Moore and published in 1859.
November 23.—This morning Major-General Conway set out from Philadelphia on his return to France. The history of the treatment this gentleman has received is so singular, that it must make a figure in the anecdotes of mankind. He has lost his commission, and he has been refused the common certificate which every officer receives at the expiration of his service, unless his delinquencies have been very substantial indeed. His crime was being accused of writing a letter to a confidential friend, communicating an opinion that the commander-in-chief (General Washington) was not equal to the great task he was charged with.
The above is extracted from a late Pennsylvania paper, and said to be written by Major-General Lee.1
