I had sent my aide, Mr. Coughlan, with the orders to Byrd, and when the line was extended and skirmishers partly covered the front, he came back to me by a direct course from Byrd to Cameron and Reilly, with the daring and intelligence which made him a model staff officer, and reported that a continuous ridge connected the brigades so that pickets could be well placed in the interval to give warning of any hostile attempt to pass between. [Footnote: Official Records, vol. xxxviii. pt. iv. pp. 620, 621. Lieutenant Coughlan was afterward killed in the heroic performance of duty at the battle of Franklin. See "Franklin," p. 114.] A small hill a few hundred yards in front of the main line better commanded the Marietta road, and upon this I directed Reilly to build a lunette for an advanced guard of a regiment and a battery. The whole affair was one of the minor class in war, but it had a special interest, in our ignorance of the topography of the country, because it revealed a way to Johnston's line of communications, which could not be seen and was not suspected when Sherman made the reconnoissance with us on the 25th, and saw the Confederate lines crossing the Powder Springs road and stretching away far beyond our right. In my field dispatch to General Schofield I said: "The possession of the end of the ridge, if we can hold it, I am now sure will prevent the enemy from extending his line along it, since it would be necessarily flanked and enfiladed by our positions. The only objection is the extension relatively to the strength of my command and the distance from supports. Upon carefully re-examining the ground my conviction is strengthened that it is exceedingly desirable to hold all we have gained, and if Hascall's place could possibly be filled by troops drawn from other parts of the line, it would give all the force needed to make a _point-d'appui_ which would be safe and exceedingly available for future movements in this direction if they become necessary. I only suggest this by way of indicating the impression made on my own mind by the position." [Footnote: Official Records, vol. xxxviii. pt. iv. p. 621.]
