Officers in Mexico have no thorough military and scientific education. There is a military school at Chapultepec, near the capital, but it has never been carefully and completely organized, nor has it furnished many men who have distinguished themselves in the field. The politicians, relying on the dramatic power of the army, made that army the means of reward and influence in civil life, by selecting its officers of all grades from every employment or occupation. Merchants, tradespeople, professional men, children of wealthy or ambitious families, all attained rank in the army by this unwise means, and the consequence has been that the majority of company, and perhaps even of field officers, was rather fitted to display the magnificent uniforms to which their grades entitle them than to discipline the rank and file when organized in battalions, regiments and divisions. The picturesque and scenic efficiency of such an army will be easily admitted, and the causes of its failure in the late war will be quite as easily understood. What can be more deplorable in battle, even for the victors, than to behold an undisciplined man badly led or driven into conflict? What can be more disastrous for an officer than to stand in the midst of blood and carnage, without knowing what to do in the moment of trial when knowledge and presence of mind are imperatively needed? Can it be surprising, therefore, to observe that the columns of Mexican gazettes and pages of Mexican pamphlets published during the war, are filled with the basest crimination and recrimination or the lamest attempts at exculpation from disgraceful defeat? A writer in the Monitor Republicano, speaking of the Mexican army, says, you have nothing to do but to read the writings of its generals from the commencement of the campaign, through the different actions and skirmishes in chronological order, and it will be seen that they have mutually called one another traitors, cowards, and imbeciles. He gives the following list of recriminations:--"Arista accused Torrejon, Ampudia and others; Torrejon Ampudia, while Uraga charged Arista; Jarregui accused Carrasco and various chiefs; Carrasco accused Jarregui and other generals; Mejia brought charges against Ampudia; Ampudia against him and several leaders, as Carrasco, Enciso and others, principal officers of the army. Urrea and others charged Parrodi with cowardice and treason; Parrodi accused Urrea and Romero, and Romero accused the famous Miramon of Mazatlan, the speculator in the goods taken by the troops of Urrea from those of Gen. Taylor.
