On June 3, just after the battle of Fair Oaks, while this army lay north of the Chickahominy, the pickets of the left wing, which was then south of the Chickahominy, and the position of which was not before known to be at any point visible from the right wing, were discovered at a distance of 3 miles across the swamp by the signal officer on duty at Hogan's house. Communication was had over the swamp and the fact established that part of our left wing was visible. The swamp was then impassable between the points, and the enemy held the ground between them. This communication was kept up for many days by officers exposed to and often under the artillery fire of the enemy. The records will show the importance of the messages transmitted and the bearing they had upon the movements of this army. The communication was between the general commanding the army, Generals W. B. Franklin, F. J. Porter, and W. F. Smith.

The officers most exposed on these stations have been once mentioned. Others who served faithfully will be mentioned hereafter.
