Note 11 — XIX SANTA ANNA PREPARES TO STRIKE September, 1846—February, 1847

The forces taking part in the campaign seem to have been 9500 infantry from San Luis, 4000 (under Mejía) stationed at Matehuala, and 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 Rápida 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.
