On the whole, I have annoyances to bear, of which you can hardly form a conception. One of them is the mutual jealousy of almost all the French officers, particularly against those of higher rank than the rest. These people think of nothing but their incessant intrigues and backbitings. They hate each other like the bitterest enemies, and endeavor to injure each other wherever an opportunity offers. I have given up their society, and very seldom see them. La Fayette is the sole exception; I always meet him with the same cordiality and the same pleasure. He is an excellent young man, and we are good friends... La Fayette is much liked, he is on the best of terms with Washington.
