Reaching the higher lands, Gen. Scott found the flower of the Mexican army entrenched among the cliffs of Churubusco. To leave the enemy in the rear was to hazard everything; and in the dangerous task of dislodging and utterly routing them the New England regiment bore a conspicuous part. In his report of the battle, Gen. Scott placed the name of Lieut. Pierce on the list of those recommended for promotion on account of gallant and meritorious conduct. The storming of Chepultepec soon followed, in which the New England regiment had literally to cross a succession of ridges and ravines, exposed to a deadly fire from the enemy among the crags. The assault was successful, and the surrender of the Mexican capital immediately followed. In this action, and in the details of patrol service during the winter, while the city was occupied by the American army, Lieut. Pierce was officially commended for the vigilant discharge of his duties. The campaign in Mexico, with its varied experiences, had, without doubt, a marked and favorable effect upon the subject of this sketch. The novelty of climate and productions, the grandeur of the scenery, and the immense natural resources of that region were not lost upon him. But of still greater value was the experience gained from association with men of large attainments, positive ideas, strong will, and comprehensive views. The majority of the army officers in that campaign were of this character; and the young soldier, at the close of the war, returned home in March, 1848, with higher aims and a better and truer estimate of the duties and responsibilities of life. Col. Pierce again engaged in business at his trade, in Manchester, which, in the meantime, had been incorporated a city. In 1849 he became a member of the city government; and in the same year was appointed a member of Gov. Dinsmoor's staff. Upon the inauguration of Gen. Franklin Pierce as president, in March, 1853, he was appointed postmaster at Manchester. This position, in the largest and most prosperous city of the state, was one of unusual labor and responsibility. Col. Pierce filled the office for eight years, and to the entire satisfaction of the citizens of all parties. On the breaking out of the rebellion, in 1861, Col. Pierce was selected by Gov. Goodwin as commander of the Second New Hampshire regiment, of the three months' troops. Having satisfactorily discharged his duties, he retired after the term of enlistment was changed to three years. The next year, September, 1862, unexpected difficulties having arisen, Gov. Berry telegraphed to Col. Pierce to take command of the Twelfth New Hampshire regiment, then completing its organization at Concord. How well he accomplished the duty assigned him was expressed in a statement, signed by the officers of the regiment, at the time of his withdrawal, in the following words:--
