HEADQUARTERS THIRD DIVISION, THIRD CORPS,

Fair Oaks, June 18, 1862.

General BARNARD,

Chief Engineer and Aide-de-Camp, Army of the Potomac:

GENERAL: If you could possibly find leisure I wish that you would ride over to examine my position. It is a line echeloned on the left rear of Hooker's position. Our left is weak, as it depends solety on the swamp, which, if it dries, can be passed; still, I am strong. The meaning of my echelon is this, that I am near enough to cover with artillery (and by advancing, by rifle firing) the ground that the enemy would have to pass over in attacking Hooker's flank. My pieces are at the same time safe, and in doing this I have also an echelon protection for myself from Hooker. But Lieutenant McAlester, to whom General Heintzelman gives a carte blanche, is about constructing a redoubt midway between Hooker's redoubt and a battery that I have on my left. This thus converts my position from an echelon to an oblique potence, deprives me of an echelon defence from Hooker, and invetes attack on me as a principal face; against the desirableness of which two things oppose, viz, that this new redoubt is placed too near woods. If these woods are sufficiently cut down in front, it will oblige us in so doing to project even beyond Hooker's line of pickets, brings the work too near certain dangerous roads and debouches (open grounds) which the enemy possess in the rear, and exposes us to the same things that Heintzelman has already been punished for in the case of Casey's redoubt, surprised and captured by an unseen line of the enemy established in the woods too near him. The left as held by me is strong as a secondary position. The moment that it is converted into a primary one it is fearfully weak. Please, therefore, to visit these parts, and call on me or on General Berry, the senior brigadier in first line, for an explanation of the roads and debouches by which an enemy can advance. The second point, perhaps, is this-we possibly may be called on to act by this flank, and I should say that the enemy's attention is not to be taken from the Williamsburg road.

With best regards, yours, truly,

P. KEARNY,

Brigadier-General, Commanding Division, Third Corps.
