It is perhaps due to a chance conversation, held some seventeen years ago in New York, that this Diary of the Civil War was saved from destruction. A Philadelphian had been talking with my mother of North and South, and had alluded to the engagement between the Essex and the Arkansas, on the Mississippi, as a brilliant victory for the Federal navy. My mother protested, at once; said that she and her sister Miriam, and several friends, had been witnesses, from the levee, to the fact that the Confederates had fired and abandoned their own ship when the machinery broke down, after two shots had been exchanged: the Federals, cautiously turning the point, had then captured but a smoking hulk.
