Major-General WARREN,

Commanding Fifth Corps:

The major-general commanding directs me to inform you that a detachment of 500 cavalry is posted on our right flank, which the commander of the brigade of infantry on this side of the Ny should communicate with. The pickets of the infantry should be well thrown out and well extended around the right. Tyler's division of infantry is massed in the vicinity of these headquarters, and is held ready for any service required of it.

I believe no one knows here who is in charge of the cavalry picket line, or where he is to be found. My line laps over his a little.
