BRIGADIER-GENERAL S. R. CURTIS

DEAR SIR:—On receipt of this, with the accompanying inclosures, you will take safe, certain, and suitable measures to have the inclosure addressed to Major-General Fremont delivered to him with all reasonable despatch, subject to these conditions only: that if, when General Fremont shall be reached by the messenger—yourself or any one sent by you—he shall then have, in personal command, fought and won a battle, or shall then be actually in a battle, or shall then be in the immediate presence of the enemy in expectation of a battle, it is not to be delivered, but held for further orders. After, and not till after, the delivery to General Fremont, let the inclosure addressed to General Hunter be delivered to him.

Your obedient servant,

A. LINCOLN.
