The Alamo, as late as 1870, was used for military purposes by the United States government, but of recent years it has been preserved purely as a monument to those brave men who lost their lives in it fighting bravely to the last a battle which they knew to be hopeless from the first. Upon the front of the building has been placed an inscription which reads, “Thermopylæ had its messenger of defeat. The Alamo had none.” The building, itself, is a low structure of the familiar Spanish mission type, and its main walls, though constructed in 1744, are almost as solid to-day as when new. The chapel of the Alamo bears the date 1757, but this was of later building than the rest of the place. The city of San Antonio owes its foundation to the establishment in 1715 by Spain of the mission of San Antonio de Valero, which in accordance with the custom of that country combined priestly enterprise with military prerogative. The Alamo was a quadrangular, central court structure built to house the troops of Spain and to sound the call to worship. It was acquired by Mexico with the rest of the Spanish possessions when this southern neighbor of the United States, in 1824, finally secured its independence from the parent country. At the time of the siege, San Antonio was a town of about 7,000 inhabitants, the vast majority Mexican. The San Antonio river which, properly speaking, is a large rivulet, divided the town from the Alamo, the former on the west side and the latter on the east. South of the fort was the Alamo village, a small suburb of San Antonio. The fort itself was in the condition in which it had been left by Cos, the Mexican general, when it had been surrendered in the fall of 1835. It contained twelve guns which were of little use in the hands of men unskilled in their use, and owing to the construction of the works most of the guns had little width of range. In command of the place at the beginning of the winter of 1835 was Colonel Neill, of Texas, with two companies of volunteers, among whom was a remnant of the New Orleans Greys. Early in 1836 Lieutenant Colonel William B. Travis, a brave and careful officer, was appointed by the Governor of Texas, which had as yet only a provisional government, to relieve Colonel Neill of his command.
