YORKTOWN, April 30, 1862
(Received Trenches between Redoubt A and Battery 5,
12.30 a.m., May 1, 1862.)

Colonel LANSING:
Man your redoubts and parallels; push forward men to watch the motions of the enemy; have the guns in Batteries 5 and 3 and Redoubt A ready to open in case of attack. I think the object is to cause us to unmask the batteries. I will have field artillery in your rear. Man your parapets and keep the men cool, and you need fear nothing. I have asked for two field batteries and two regiments to be posted in your rear near my old headquarters as a reserve. Unless the enemy advances in force I don't want the Batteries 5 and 2 to open. It is only to compel us to show what we are about that he is now working. Keep your men cool--don't let them be stampeded. If anything be done it will be just at daybreak, when the new guards will be there. Any other party coming

Garrison--Captain Arnold's light company, one hundred and twenty men, and Seventeenth New York, Colonel Lansing. The supply of ammunition for these forts, although not complete, is sufficient for an emergency, averaging about one hundred rounds per gun, and the amount is being increased as rapidly as possible. The field batteries are in a very unsatisfactory condition, many of them, but as fast as the materials can be procured they are refitting.

General FITZ JOHN PORTER:
Have you provided the field batteries Lansing asks for? I will have the regulars ready before daybreak and some of Hunt's batteries harnessed up. Shall I do more than this?

Brig. Gen. SETH WILLIAMS
Asst. Adjt. Gen., Headquarters Army of the Potomac:

GENERAL:
In my recommendations for promotions by brevet, presented in July last, I unintentionally omitted the name of Col. Henry S. Lansing, Seventeenth New York Volunteers and captain Twelfth U.S. Infantry, for gallant and meritorious conduct at the battle of Hanover Court-House, May 27, 1862. He was conspicuous there in handling his regiment, which, with others, drove the enemy from their ground and captured one field piece and many prisoners.

HEADQUARTERS FIFTH CORPS
October 14, 1862

Brig. Gen. SETH WILLIAMS
Asst. Adjt. Gen., Headquarters, Army of the Potomac:

GENERAL:
I respectfully present to the consideration of the commanding general the following recommendations for promotions, with the hope that they may be favorably presented to the honorable Secretary of War: Col. H. S. Lansing, Seventeenth New York Volunteers (captain Twelfth U.S. Infantry), to the rank of brigadier-general. The activity and energy of this officer from the commencement of the war commend him to the consideration of the commanding general for reward. His efficient services in the field, commanding his regiment and at times a brigade or an expeditionary force, prove his soldierly qualities and his ability to fill the position. I would like to have him command a brigade of this corps.

I am, general, very respectfully, your obedient servant,
F. J. PORTER
Major-General, Commanding
