Previous to the offer of the attorney-generalship, the appointment of United States Senator had been tendered to Pierce by Governor Steele, and declined. It is unquestionable that, at this period, he hoped and expected to spend a life of professional toil in a private station, undistinguished except by the exercise of his great talents in peaceful pursuits. But such was not his destiny. The contingency to which he referred in the above letter, as the sole exception to his purpose of never being separated from his family, was now about to occur. Nor did he fail to comport himself as not only that intimation, but the whole tenor of his character, gave reason to anticipate. During the years embraced in this chapter,--between 1842 and 1847,--he had constantly taken an efficient interest in the politics of the state, but had uniformly declined the honors which New Hampshire was at all times ready to confer upon him. A democratic convention nominated him for governor, but could not obtain his acquiescence. One of the occasions on which he most strenuously exerted himself was in holding the democratic party loyal to its principles, in opposition to the course of John P. Hale. This gentleman, then a representative in Congress, had broken with his party on no less important a point than the annexation of Texas. He has never since acted with the Democracy, and has long been a leader of the free soil party. In 1844 died Frank Robert, son of Franklin Pierce, aged four years, a little boy of rare beauty and promise, and whose death was the greatest affliction that his father has experienced. His only surviving child is a son, now eleven years old. CHAPTER IV. THE MEXICAN WAR. When Franklin Pierce declined the honorable offer of the attorney-generalship of the United States, he intimated that there might be one contingency in which he would feel it his duty to give up the cherished purpose of spending the remainder of his life in a private station. That exceptional case was brought about, in 1847, by the Mexican War. He showed his readiness to redeem the pledge by enrolling himself as the earliest volunteer of a company raised in Concord, and went through the regular drill, with his fellow-soldiers, as a private in the ranks. On the passage of the bill for the increase of the army, he received the appointment of colonel of the Ninth Regiment, which was the quota of New England towards the ten that were to be raised. And shortly afterwards,--in March, 1847,--he was commissioned as brigadier-general in the army; his brigade consisting of regiments from the extreme north, the extreme west, and the extreme south of the Union.
