exceed 20,286. This number was believed by the adjutant general to be "much beyond" the number of effectives.
There were supposed to be in the field 19,818 regulars and (aside from 803 on California service) 21,124 volunteers (officers and men); en route 1691 regulars, 100 volunteers: total (including the California men), 43,536. Scott's army (regulars) was figured as 15,071 in the field, 1396 en route, 555 at Vera Cruz, 79 at Tampico; (volunteers) in the field and at Tampico, 14,955. His operating army, including the sick and the disabled, was estimated as about 30,209. Wool's army was figured as (regulars) 3,642 in the field, 295 en route and (volunteers) 2790: total, 6727. Price was believed to have 255 regulars (dragoons), 2902 volunteers; and Mason (California) 216 regulars (one company of dragoons and one company of artillery), 803 volunteers (adj. gen.'s report, Sen. 1; 30, 1, p. 72). All the figures were approximate and there were discrepancies in the reckoning.
Nov. 20 the adjutant general stated the regulars sent to Scott as reinforcements thus: of the old establishment (absent companies, reorganized companies and recruits), 5564; new establishment (troops raised and organized after March 4, 1847), five companies of Third Dragoons, the Ninth, Eleventh, Twelfth (nine companies), Fourteenth and Fifteenth Infantry, the Voltigeurs, and recruits for the same, 6345 (62to Scott); and also six companies (360) of Marines under Lieut. Colonel Watson. Scott's returns were infrequent or were lost on the way. Perhaps he dared not run the risk of exposing them to guerillas. Hence as a rule one must accept general statements. Quitman's division, being now very small, was broken up, and he was permitted to report at Washington for a new command (Claiborne, Quitman, i, 395). Asa rule no officer was permitted to leave the army except "with a view to the good of the service or the recovery of health" (61Scott to Patterson, Oct. 28, 1847). Oct. 22 even leaves of absence that had been granted or promised were cancelled. The government ordered the reinforcements to leave Vera Cruz promptly, and Bankhead was put in the place of Wilson there in order to obtain more efficient management (62adj. gen. to Scott, Nov. 9). After about the middle of October the troops at Mexico were thoroughly drilled, and by the middle of November came to be better disciplined than ever before.
April 29, 1847, although the 12-months army was about to disband, Marcy requested Patterson and Butler to remain in the service as major generals, and Marshall, Lane and Shields to remain as brigadier generals. Marshall arrived at Mexico City January 21, 1848. It is not possible to state how many troops came with each of the officers. Col. Hays brought five companies of Rangers. Lt. Col. Johnston had about 1300 men when at Puebla. In general about half of a command fell out from sickness and other causes between Vera Cruz and Mexico (125Bonham to mother, Dec. 7, 1847). Fruits, liquor, insufficient clothing and at this time the measles were the chief causes of sickness.
Scott's announcement (65gen. orders 376) was dated Dec. 15. Jan. 6 Scott had 14,964, of whom 11,162 were effectives (Ho. 60; 30,1, p. 1061). By Feb. 13 his rank and file amounted to 26,910, and 2000 recruits were en route (62adj. gen. to Cass, Mar. 9, 1848). Though 5546 of the rank and file and 181 officers were then sick, he had been for some time strong enough to occupy Zacatecas and San Luis Potosí, but the peace negotiations (chap. xxxii) affected his plans. The new posts were at Río Frio (between Mexico and Puebla), and the national bridge and San Juan
