1000 (under Parrodi) from Tula, 6000 cavalry in four brigades (Torrejón at Las Bocas near S. L. P., Juvera at Venado, Andrade at Cedral, and Miñón at La Encarnación), and 900 engineers, artillery and sappers — a total of 21,400 including officers. These numbers are taken from Ráida Ojeada and from a San Luis letter (the figures of which were stated positively to have come from a member of Santa Anna's staff) printed in El Republicano of February 12, which substantially agree. Santa Anna's figures were smaller but perhaps did not include Miñón's and Parrodi's troops. Those of the Spanish minister were somewhat larger. There seem to have been seventeen guns (three 24-pounders and three 16's, all of which were siege or fortress guns, and for field pieces five 12's, five 8's and a 7-inch howitzer) which, as well as most of the ammunition, appear to have gone forward January 27. Urrea was at the same time to pass from Tula into Tamaulipas, strike at Taylor's communications and threaten Monterey. Probably there were bodies of irregulars at points not named above.
It occurs to the author at this point to remark that consistency in the use of the article in geographical names is hardly practicable. Even Mexican maps have not been consistent; and for us it would (e.g.) be an affectation to use the article with such well-known names as Puebla and Saltillo.
12. At certain points in the desert there were large wells; and in each of these a wide wheel, carrying buckets, was turned by mule power.
13. The main part of the army arrived Feb. 17-19 (Apuntes, 96). Taylor thought he could not move more than about 6000 men some 125 miles (supposed to be about 140) from a well-stocked base, Camargo, through a region supplied with water, subsistence and forage, and could not transport 18-pounders (chap. xi, note 5). After Miñón advanced to Potosí, Andrade occupied La Encarnación (night of Feb. 11). The wheel pumps were then set in operation, but by Feb. 19 they were worn out. The only ample supply of water was then seven or eight miles away, but it had to be used for the animals. The distance from S. L. Potosí to Agua Nueva by rail is about 223 miles.
14. Feb. 19 two brigades of cavalry had not arrived. The figures may or may not have included these and Miñón's force. Probably they did include many whose duties kept them from the firing line (Republicano, May 3, 1847). The original reports of the officers regarding numbers and operations have disappeared from 76.
