or become too much scattered, or you will be lost. Do not allow any personal gain to lead you off, which would only bring you to an ignominious death at the hands of citizens. Keep well together and obey orders strictly and all will be well; but on no account scatter too far, for in union there is strength. With strict obedience to orders and fearlessness in the execution you will be sure to succeed. We will join the main force on the other side of the city, or perhaps meet them inside. Many of you may fall; but if there is any man here not willing to sacrifice his life in such a great and glorious undertaking, or who does not feel capable of meeting the enemy in such a desperate fight as will follow. let him step out, and he may go hence to the arms of his sweetheart and read of the braves who swept through the city of Richmond. We want no man who cannot feel sure of success in such a holy cause. We will have a desperate fight, but stand up to it when it does come and all will be well. Ask the blessing of the Almighty and do not fear the enemy.

U. DAHLGREN,

Colonel, Commanding.

[Sub-inclosure Numbers 2.]

HEADQUARTERS THIRD DIVISION, CAVALRY CORPS, -- - --, 1864.

Guides, pioneers (with oakum, turpentine, and torpedoes), signal officer, quartermaster, commissary, scouts, and picket men in rebel uniform. Men will remain on the north bank and move down with the force on south bank, not getting ahead of them, and if the communication can be kept up without giving an alarm it must be done; but everything depends upon a surprise, and no one must be allowed to pass ahead of the column. Information must be gathered in regard to the crossing of the river, so that should we be repulsed on the south side we will know where to recross at the nearest point. All mills must be burned and the canal destroyed; and also everything which can be used by the rebels must be destroyed, including the boats on the river. Should a ferry-boat be seized and can be worked, have it moved down. Keep the force on the south side posted of any important movement of the enemy, and in case of danger some of the scouts must swim the river and bring us information. As we approach the city the party must take great care that they do not get ahead of the other party on the south side, and must conceal themselves and watch our movements. We will try and secure the bridge to the city, 1 mile below Belle Island, and release the prisoners at the same time. If we do not succeed they must then dash down, and we will try and carry the bridge from each side. When necessary, the men must be filed through the woods and along the river bank. The bridges once secured, and the prisoners loose and over the river, the bridges will be secured and the city destroyed. The men must keep together and well in hand, and once in the city it must be destroyed and Jeff. Davis and cabinet killed. Pioneers will go along with combustible material. The officer must use his discretion about the time of assisting us. Horse and cattle which we do not need immediately must be shot rather than left. Everything on the canal and elsewhere of service to the rebels must be destroyed. As General Custer may follow me, be careful not to give a false alarm.
