The fearless stand of Preston King in supporting the Wilmot Proviso[86] took root among the Radicals, as Seward prophesied, and the exclusion of slavery from territory obtained from Mexico, became the dominant Democratic issue in the State. Because of their approval of this principle the Radicals were called "Barnburners." Originally, these factional differences, as noted elsewhere, grew out of the canal controversy in 1838 and in 1841, the Conservatives wishing to devote the surplus canal revenues to the completion of the canals—the Radicals insisting upon their use to pay the state debt. Under this division, Edwin Croswell, William C. Bouck, Daniel S. Dickinson, Henry A. Foster, and Horatio Seymour led the Conservatives; Michael Hoffman, John A. Dix, and Azariah C. Flagg marshalled the Radicals. When the Conservatives, "hankering" after the offices, accepted unconditionally the annexation of Texas, they were called Hunkers. In like manner, the Radicals who sustained the Wilmot Proviso now became Barnburners, being likened to the farmer who burned his barn to get rid of rats. William L. Marcy, Silas Wright, Benjamin F. Butler, and the Van Burens took no part in the canal controversy; but after Martin Van Buren's defeat in 1844 Marcy became a prominent Hunker and entered Polk's Cabinet, while Wright, Butler, and the Van Burens joined the Barnburners.
Hostilities between the Hunkers and Barnburners, growing out of the slavery question, began at the Democratic state convention, which convened at Syracuse, September 7, 1847.[87] Preceding this meeting both factions had been active, but the Hunkers, having succeeded in seating a majority of the delegates, promptly voted down a resolution embodying the principle of the Wilmot Proviso. Then the Barnburners seceded. There was no parleying. The breach opened like a chasm and the secessionists walked out in a body. This action was followed by an address, charging that the anti-slavery resolution had been defeated by a fraudulent organisation, and calling a mass convention for October 26, "to avow their principles and consult as to future action." This meeting became a gathering of Martin Van Buren's friends. It did not nominate a ticket, which would have defeated the purpose of the secession; but, by proclaiming the principles of Free-soil, it struck the keynote of popular sentiment; divided the Democratic party, and let the Whigs into power by thirty thousand majority. It made Millard Fillmore comptroller, Christopher Morgan secretary of state, Alvah Hunt treasurer, Ambrose L. Jordan attorney-general, and Hamilton Fish lieutenant-governor to fill the vacancy occasioned by Addison Gardiner's election to the new Court of Appeals. The president of this seceders' mass-meeting was Churchill C. Cambreling, an old associate of Martin Van Buren, but its leader and inspiration was John Van Buren. He drafted the address to the people, his eloquence made him its chief orator, and his enthusiasm seemed to endow him with ubiquity.
John Van Buren was unlike the ordinary son of a President of the United States. He did not rely upon the influence or the prestige of his father.[88] He was able to stand alone—a man of remarkable power, who became attorney-general in 1845, and for ten years was a marked figure in political circles, his bland and convulsing wit enlivening every convention and adding interest to every campaign. But his chief interest was in his profession. He was a lawyer of great distinction, the peer and often the opponent of Charles O'Conor and William H. Seward. "He possessed beyond any man I ever knew," said Daniel Lord, "the power of eloquent, illustrative amplification, united with close, flexible logic."[89]
John Van Buren had, as well, a picturesque side to his life. In college he was expert at billiards, the centre of wit, and the willing target of beauty. Out of college, from the time he danced with the Princess Victoria at a court ball in London at the age of twenty-two, to the end of his interesting and eventful life, he was known as "Prince John." His remarkable gifts opened the door to all that was ultra as well as noble. He led in the ballroom, he presided at dinners, he graced every forum, and he moved in the highest social circles. Men marvelled at his knowledge, at his unfailing equanimity, and at his political strength; but even to those who were spellbound by his eloquence, or captivated by his adroit, skilful conduct of a lawsuit, he was always "Prince John." There was not a drop of austerity or intolerance or personal hatred in him. The Dutch blood of his father, traced from the Princes of Orange to the days of the New Netherland patroons, kept him within the limits of moderation if not entirely unspotted, and his finished manners attracted the common people as readily as they charmed the more exclusive.
John Van Buren's acceptance of Free-soilism did not emanate from a dislike of slavery; nor did Free-soil principles root themselves deeply in his nature. His father had opposed the admission of Texas, and the son, in resentment of his defeat, hoping to make an anti-slavery party dominant in the State, if not in the nation, proclaimed his opposition to the extension of slavery. But, after the compromise measures of 1850 had temporarily checked the movement, he fell back into the ranks of the Hunkers, aiding President Pierce's election, and sustaining the pro-slavery administration of Buchanan. In after years Van Buren frequently explained his connection with the Free-soil revolt by telling a story of the boy who was vigorously removing an overturned load of hay at the roadside. Noticing his wild and rapid pitching, a passer-by inquired the cause of his haste. The boy, wiping the perspiration from his brow as he pointed to the pile of hay, replied, "Stranger, dad's under there!"
But whatever reasons incited John Van Buren to unite with the Free-soilers, so long as he advocated their principles, he was the most brilliant crusader who sought to stay the aggressiveness of slavery. From the moment he withdrew from the Syracuse convention, in the autumn of 1847, until he finally accepted the compromise measures of 1850, he was looked upon as the hope of the Barnburners and the most dangerous foe of the Hunkers. Even Horatio Seymour was afraid of him. He did not advocate abolition; he did not treat slavery in the abstract; he did not transcend the Free-soil doctrine. But he spoke with such power and brilliancy that Henry Wilson, afterward Vice President, declared him "the bright particular star of the revolt."[90] He was not an impassioned orator. He spoke deliberately, and rarely with animation or with gesture; and his voice, high pitched and penetrating, was neither mellow nor melodious. But he was marvellously pleasing. His perennial wit kept his audiences expectant, and his compact, forceful utterances seemed to break the argument of an opponent as a hammer shatters a pane of glass. So great was his popularity at this time, that his return to the Democratic party became a personal sorrow to every friend of the anti-slavery cause. "Indeed, such was the brilliant record he then made," says Henry Wilson, "that had he remained true to the principles he advocated, he would unquestionably have become one of the foremost men of the Republican party, if not its accepted leader."[91]
Several historic conventions followed the secession of the Barnburners. Each faction held a state convention to select delegates to the Democratic national convention which met in Baltimore on May 22, 1848, and, on the appointed day, both Hunkers and Barnburners presented full delegations, each claiming admission to the exclusion of the other.[92] It was an anxious moment for Democracy. New York held the key to the election; without its vote the party could not hope to win; and without harmony success was impossible. To exclude either faction, therefore, was political suicide, and, in the end, the vote was divided equally between them. To the politician, anxious for party success and hungry for office, perhaps no other compromise seemed possible. But the device failed to satisfy either side, and Lewis Cass was nominated for President without the participation of the State that must elect or defeat him.
Returning home, the Barnburners issued an address, written by Samuel J. Tilden, who fearlessly called upon Democrats to act independently. This led to the famous convention held at Utica in June. Samuel Young presided, Churchill C. Cambreling was conspicuous on the stage, David Dudley Field read a letter from Martin Van Buren condemning the platform and the candidate of the Baltimore convention, and Benjamin F. Butler, Preston King, and John Van Buren illuminated the principles of the Free-soil party in speeches that have seldom been surpassed in political conventions. In the end Martin Van Buren was nominated for President.
This assembly, in the ability and character of its members, contained the better portion of the party. Its attitude was strong, defiant, and its only purpose apparently was to create a public sentiment hostile to the extension of slavery. Nevertheless, it was divided into two factions, one actuated more by a desire to avenge the alleged wrongs of Van Buren, than to limit slavery. To this class belonged Churchill C. Cambreling, Samuel J. Tilden, John A. Dix, Sanford E. Church, Dean Richmond, John Cochrane, Benjamin F. Butler, and the Van Burens. On the anti-slavery side, Preston King, David Dudley Field, James S. Wadsworth, and William Cullen Bryant were conspicuous. Seven years later, these men were quick to aid in the formation of the Republican party; while the former, for the most part, continued with the Democratic party. But, whatever the motives that prompted them, their action strengthened the Buffalo convention[93] which met on August 9, 1848, giving an impetus to the anti-slavery cause too strong for resentment or revenge to guide it.
There have been many important meetings in the history of American politics, but it may well be doubted if any convention, during the struggle with slavery, ever exalted the hearts of those who took part in it more than did this assembly of fearless representatives of the Free-soil party in Buffalo, the Queen City of the Lakes. The time was ripe for action, and on that day in August, men eminent and to grow eminent, sought the shade of a great tent on the eastern shore of Lake Erie. Among them were Joshua R. Giddings, the well-known Abolitionist; Salmon P. Chase, not yet famous, but soon to become a United States senator with views of slavery in accord with William H. Seward; and Charles Francis Adams who had already associated his name with that of his illustrious father in the growth of anti-slavery opinions in New England. Chase presided over the convention and Adams over the mass-meeting. At the outset, it was boldly asserted that they had assembled "to secure free soil for a free people;" and in closing they thrilled the hearts of all hearers with the memorable declaration that rang throughout the land like a blast from a trumpet, "We inscribe on our banner Free Soil, Free Speech, Free Labour, and Free Men." It was a remarkable convention in that it made no mistakes. Lewis Cass represented the South and its purposes, while Zachary Taylor lived in the South and owned four hundred slaves. Neither of these men could be supported; but, in the end, rather than put a fourth candidate into the field, it was resolved unanimously to indorse Martin Van Buren for President and Charles Francis Adams for Vice President. Daniel Webster ridiculed the idea of "the leader of the Free-spoil party becoming the leader of the Free-soil party;" but Charles Sumner, whose heart was in the cause, declared that "it is not for the Van Buren of 1838 that we are to vote, but for the Van Buren of to-day—the veteran statesman, sagacious, determined, experienced, who, at an age when most men are rejoicing to put off their armour, girds himself anew and enters the list as a champion of freedom."[94] To give further dignity and importance to the Free-soil movement, the nomination of John P. Hale, made by the Abolitionists in the preceding November, was withdrawn, and John A. Dix, then a Democratic senator, accepted the Barnburners' nomination for governor.[95]
