PREFACE
2. A second reason for preparing this history was that a number of important topics — such as the conditions existing in the two countries just before the war, the war in American politics, our conduct and methods in occupied territory, the finances of the war, its foreign relations, etc. — had been treated most superficially or not at all, In the third place it was hoped to handle more carefully the material previously used. The bound volumes entitled "Archive de Guerra" in the Archive General y Público at Mexico occupy some 200 feet of shelf room, and the papers examined in the Archive de Guerra y Marina, which had to be examined one by one, would probably, if placed one on another, make a pile sixty feet high.
As will be seen from the detailed account of the MS. sources (appendix), the author did not visit the archives of all the Mexican states and cities. This was because nothing further of local value could he hoped for, and because the practice of communicating from state to state copies of important documents made it seem unnecessary to continue in those directions. The results in Peru and Colombia were negative, but this fact had a positive significance, for there were reasons to look for an active sympathy and correspondence with Mexico in those quarters The author planned to examine the Prussian archives, but the outbreak of the great war prevented him from doing so. From other trustworthy sources, mostly unpublished, he fully understood the attitude of that government, however (chap. xxxv). The reports of the Prussian representative at Mexico cannot have been reliable, both because of his personal characteristics and because for several reasons he did not stand within the inner circle, and probably, since his government felt scarcely any interest in the war, they were not full. Hence it is not believed that anything of material value has been lost through the impossibility of examining them Of some of the newspaper files only scattered portions were found. Many newspapers, as well as many books and pamphlets, were read to ascertain the general temper, social state, and political conditions of the two countries, and it appeared unnecessary to set down references which would have been almost innumerable — to such literature, The author contemplated at one time a critical discussion of the sources, but he soon found that this would require too much space. It would in fact make a volume. For additional information regarding the sources one may consult an article of the author's that appeared in The Military Historian and Economist, vol. i, no. 1.
