well supported by the buoys, the slack line (three fathoms of which was kept in hand for safety) thrown overboard, and all set adrift within 800 yards of the ship, and 400 yards of the battery on the bluff above the point. So near were we that voices were heard on the shore and Mr. Moore reported a boat about 100 yards off, which, however, I did not see, being too much engaged in preparing the magazine for its service. Pulling back a short distance and hearing no explosion we returned to the ship which we found cleared for action and ready to cover us in event of being attacked, and the boats had just been hoisted up when signal lights were observed flashing in the vicinity of the point with considerable rapidity, indicating a suspicion on the part of the enemy that an attacked of some kind was intended. Leaving our anchorage we steamed rapidly up the river and took up our former position off this place about 12:30 at night. On going to the crosstrees this morning two ships were seen at anchor off the point, and later in the day when seen from Warwick River, where Commander Tucker and I went to get a better view of them, they were apparently unharmed, and I concluded that the magazine could not have fouled them, though planted fairly and in good drifting distances and with an interval between of some 200 feet, perhaps somewhat less as the line became entangled while playing out.
I have thus minutely described to you, sir, the whole operation, believing, as its originator, it would be interesting to you, and, perhaps, serve as a guide in the further prosecution of this mode of warfare.
I beg leave to return my sincere thanks to Commander Tucker, Lieutenant Powell and other men of the "Patrick Henry," for their hearty co-operation, and I particularly desire to call your attention to the
