We commenced the chase at 4.30 p.m. Unfortunately our decks were loaded with coal; however, we made a clean thirteen knots. At first it seemed as if we were coming up with the chase, so much so that I felt inclined to fire the long bow gun at her. But I always think and I say from blockade-running experience that firing more or less injures a vessel's speed; so I refrained from doing so. As night closed in a beautiful moon rose and made everything as clear as day. The equality of our speed was most remarkable, inasmuch as the distance between us did not vary a hundred yards in an hour. All night we were watching, measuring distances with nautical instruments, &c., hoping at moments that we were nearer, despairing at others that she was gaining from us. We threw overboard fifty or sixty tons of coal, to no avail; we could not get within shot of the 'Livadia,' to capture which I would have given all I possessed. As day broke we saw the crew of the 'Livadia' busily employed throwing overboard coal and water. Sebastopol was in sight, and she was running for dear life to that haven of safety. Lightening her had certainly a good effect, for it was sadly evident to me that on doing so she drew ahead a little, but very little. Now I hoped she would burst her boiler or break down ever so little; but so it was not fated, and the Emperor's yacht escaped by the skin of her teeth into Sebastopol, under the protection of batteries that opened a tremendous fire on my ship on my approaching, forgetful of their existence. I was obliged to clear out of that pretty sharply or we should have been sunk. An ironclad corvette that accompanied me, though some miles astern at the finish, ran so close in that she had her rudder shot away, and we had the unpleasant task of towing her out under a fire more like a hailstorm of shot and shell than anything I can compare it to. I am told the 'Livadia' would have shown fight. I have no doubt she would; Russians always fight well: but I think the result would not have been doubtful, and the Emperor's crockery and glass, to say nothing of the magnificent gettings-up in the cabins, would have lost much of their lustre during an engagement. So the glory of taking the Emperor's yacht into the Bosphorus was not to be mine. I cannot express my disappointment at losing such a chance. The only consolation I have is that I really believe the brave Russians would have blown her up, rather than allow such a disgrace to fall on their flag.
