Scott now had about 14,000 men, some 2500 of whom lay, however, in the hospitals, while about six hundred were convalescents too feeble for an ordinary day's march. The cavalry, led by Colonel Harney, included portions of the three dragoon regiments under Captain Kearny, Major Sumner and Major McReynolds. For artillery, besides the siege train, there were the field batteries of Duncan, Taylor, Steptoe and others,[24.28] and the howitzer and rocket battery of Talcott. Brevet Major General Worth's division of infantry, known as the First, consisted of Brevet Colonel Garland's brigade (Second and Third Artillery, Fourth Infantry and a light battalion) and the brigade of Colonel Clarke, which included the Fifth, Sixth and Eighth Infantry. The Second Division, commanded by Brigadier General Twiggs, was composed of the regiments under Brevet Brigadier General Persifor F. Smith (Mounted Riflemen, First Artillery and Third Infantry) and Brevet Colonel Riley (Fourth Artillery, Second and Seventh Infantry). Major General Pillow, higher in rank than the brave, able and experienced Worth, a professional soldier, had the Eleventh and Fourteenth Infantry and the Voltigeur regiment under Brigadier General Cadwalader, a polished veteran of Chestnut Street parades, Philadelphia, and the Ninth, Twelfth and Fifteenth Infantry under the gentlemanly Franklin Pierce, a social and political hero of Concord, New Hampshire; while General Shields's brigade (New York and South Carolina volunteers) and Lieutenant Colonel Watson's, consisting of three hundred marines and a detachment of the Second Pennsylvania, made up the division of Quitman, an excellent person and politician, who had now reached the highest military grade.[24.29]
