October 22, Thursday. Went this afternoon by invitation of General Barnard to visit Fort Foote, just completed, some eight miles below the city. A pleasant party, — Chase, Generals Barnard, Augur, Barry, Admiral Davis, etc., with ladies. It is a strong position and a vast amount of labor has been expended, — uselessly expended. In going over the works a melancholy feeling came over me, that there should have been so much waste, for the fort is not wanted, will never fire a hostile gun. No hostile fleet will ever ascend the Potomac.
