FORT LYON, COLO. TER., June 3, 1864.
Lieutenant J. S. MAYNARD,
            Actq. Asst. Adjt. General, District of Colorado:
    SIR: I have the honor to report, for the information of the colonel commanding, that I have just received a dispatch from Lieutenant Wilson, on outpost duty, to the effect that he had certain information of the approach of a body of Texans toward this post. From a Government wagon-master he had learned of the capture of a train on the Cimarron, by what is supposed to be an advance guard of the rebels. The two sections of the independent battery left here this morning for Fort Larned. I have sent an order for them to halt until further orders. I will send by this express for any detachments en route to this post from the west to make all haste. I have no guns, the two howitzers belonging to Lieutenant Eayre's command having been detained at Larned by the commanding officer of that post. I will be as vigilant as possible--give them another taste of Pigeon's Ranch and Apache Ca�on and see how they like it. I can hold my own against twice my number, from the fact of my men and horses being fresh, while theirs must be the contrary. Will send forward dispatch when anything of importance transpires.
        I am, sir, with respect, your obedient servant,
                                                                E. W. WYNKOOP,
    Major, Commanding Fort Lyon.
