The follotwing pnges are designed to record, in a brief manner, those facts in reference to the war in Mexico, worthy of preservation. It com prehends the substarlce ot larger works, and ismore convenient for reference. Lists of killed and wounded are given as fully and accurately as the oificial and authoritive reports would admit. It Is painft l to contemplate, and especially dcs cribe the scenes of the battle field-the streams of blood-the groans of the wounded and dying-the hundreds or thousailds slain-the gasp of death-the crushed hopes-undying spirits thus ushered sudden ly and awfulfy into the presence of their Judge, per haps unprepared-it is npalling and we would turn nway and weep for poor, depraved humanity. Still it is desirable that the facts hould b e laid before the public. How many wives, at the commencement of the war, parted with their companions never to meet again in this world, and are now eager to know all thc circumstances connected with the war How many parcnts, bereft of dear children, how many brothers and sisters, deprived of those whom they loved, are intensely anxious to hear all the particulars of each battle We present these pages to the public hoping the tragical scenes here described may deter others from imbibing a war spirit.

In order to accomplish this object, as Mexico was opposed to it, it was agreed between our government and that of Tcxas, that the former should send upon the borders of Tcxas, an armed force suficient to put down any opposition from hlexico. Accordingly Zachary Taylor, Col. of the 6th Regiment of Infantry, was appointed to take command of these forces. IIe repaired to Fort Jessup, Louisana, and found that post garrisoned by seven companies of the 2d regiment of Dragoons, under the command of Col. D. E. Twiggs. hIay loth, 1844, eight companies of the 3d Kegi ment of Infantry, stationed at Jefferson Barracks, MissouriS repaired to thc same place, commanded by Lieutenant Col. E. A. Hitchcock.
