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.[1]
The troops that had been waiting at Puebla were by this time in fine training; and the new men, besides receiving the soldier's baptism on the way up, had learned at least the value of discipline and skill. The former had become to a large extent acclimated, and they felt an entire confidence in their commander, which, fully accredited by his victories, extended promptly to the reinforcements. The essential clothing had been purchased or manufactured. Thanks to indefatigable exertions a large stock of provisions had been accumulated, and at a cost of 15 per cent funds for the march to the capital had been raised. Although time had permitted the friendly sentiments and reasonable arguments of Scott's proclamation to leaven the people, and association with the Americans had refuted the calumnies previously effective against them, our officers and men expected hard fighting. Thoughts of distant homes and of near perils were silvering many a fine head. There were no good laughers in the army now. But in an equal degree hearts were nerved. Mentally the cost of success, figured without discount, was already paid. All felt eager to advance. And when, anticipating Pierce's arrival by one day, Scott gave the order, a soldier's joy lighted up their bronzed features.[2]
