"On arriving in Isle of Wight County, on the 2d of August, we learned of immense supplies of stores being landed at City Point; and for the purpose, by stratagem, of introducing our machine upon the vessels there discharging stores, started for that point. We reached there before day-break on the 9th of August last, having travelled mostly by night, and crawled upon our knees to pass the east picket line. Requesting my companion to remain behind about half a mile, I approached cautiously the wharf, with my machine and powder covered by a small box. Finding the captain had come ashore from a barge then at the wharf, I seized the occasion to hurry forward with my box. Being halted by one of the wharf sentinels, I succeeded in passing him by representing that the captain had ordered me to convey the box on board. Hailing a man from the barge, I put the machine in motion, and gave it in his charge. He carried it aboard. The machine contained about twelve pounds of powder. Rejoining my companion we retired to a safe distance to witness the effect of our effort. "In about an hour the explosion took place. Its effect was communicated to another barge beyond the one operated upon, and also to a large wharf building containing their stores (enemy's), which was totally destroyed. The scene was terrific, and the effect deafened my companion to an extent from which he has not recovered. My own person was severely shocked, but I am thankful to Providence that we have both escaped without injury. We obtained and enclose slips from the enemy's newspapers, which afford their testimony of the terrible effects of the blow. The enemy estimate the loss of life at fifty-eight killed and one hundred and twenty-six wounded, but we have reason to believe it greatly exceeded that. "The pecuniary damage we heard estimated at four millions of dollars; but of course we can give you no account of the extent of it exactly. I may be permitted, Captain, here to remark _that a party of ladies_, it seems, were killed by this explosion. It is saddening to me to realize the fact that the terrible effects of war [he should have added as thus conducted] induce such consequences; but when I remember the ordeal to which our own women have been submitted, and the barbarities of the enemy's crusade against us and them, my feelings are relieved by the reflection that whilst this catastrophe was not _intended_ by us, it amounts only, in the providence of God, to _just retribution_." Hear the pious scoundrel salving his conscience with the old cry of "just retribution!" The following will explain the agency by which boats on the Ohio and Mississippi rivers, and the United States Hospital at Louisville, Ky., were burned. It is the testimony of Edward Frazier before the Commission:--
