Flat Top Mountain. — A clear, hot, healthy summer day. General McClellan telegraphs that he has had a “desperate battle”; a part of his army across the Chickahominy, is attacked “by superior numbers”; they “unaccountably break”; our loss heavy, the enemy's “must be enormous”; enemy “took advantage of the terrible storm.” All this is not very satisfactory. General McClellan's right wing is caught on the wrong side of a creek raised by the rains, loses its “guns and baggage.” A great disaster is prevented; this is all, but it will demonstrate that the days of Bull Run are past.
