The discretionary authority given to General Gaines to cross the Sabine and to occupy a position as far West as Nacogdoches, in case he should deem such a step necessary to the protection of the frontier and to the fulfillment of the stipulations contained in our treaty with Mexico, and the movement subsequently made by that officer have been alluded to in a former part of this message. At the date of the latest intelligence from Nacogdoches our troops were yet at that station, but the officer who has succeeded General Gaines has recently been advised that from the facts known at the seat of Government there would seem to be no adequate cause for any longer maintaining that position, and he was accordingly instructed, in case the troops were not already withdrawn under the discretionary powers before possessed by him, to give the requisite orders for that purpose on the receipt of the instructions, unless he shall then have in his possession such information as shall satisfy him that the maintenance of the post is essential to the protection of our frontiers and to the due execution of our treaty stipulations, as previously explained to him. Whilst the necessities existing during the present year for the service of militia and volunteers have furnished new proofs of the patriotism of our fellow citizens, they have also strongly illustrated the importance of an increase in the rank and file of the Regular Army. The views of this subject submitted by the Secretary of War in his report meet my entire concurrence, and are earnestly commended to the deliberate attention of Congress. In this connection it is also proper to remind you that the defects in our present militia system are every day rendered more apparent. The duty of making further provision by law for organizing, arming, and disciplining this arm of defense has been so repeatedly presented to Congress by myself and my predecessors that I deem it sufficient on this occasion to refer to the last annual message and to former Executive communications in which the subject has been discussed.
