A bill was introduced August 8, 1846, which authorized the placing of $2,000,000 at the disposal of President Polk for the purpose of negotiating peace with Mexico and the crucial hour in our history had arrived. The prospect of the erection of future slave States out of Mexican territory aroused the anti-slavery sentiment of the North, and among the most pronounced of the dozen or more anti-slavery Democrats was David Wilmot.
At a conference of anti-slavery Democrats was presented what became known as the Wilmot proviso, of which the text was a repetition of the Jefferson proviso to the ordinance of 1787, except that it was framed for the present situation. The following is the full text: “Provided, that as an expressed and fundamental condition to the acquisition of any territory from the Republic of Mexico by the United States, by virtue of any treaty that may be negotiated between them, and to the use by the Executive of the moneys herein appropriated, neither slavery nor involuntary servitude shall ever exist in any part of such territory, except for crime whereof the party shall be first duly convicted.”
When offered by Wilmot the proviso produced the utmost consternation in the House, as many members had become alarmed at the anti-slavery sentiment in their districts. The House was in committee of the whole, and to the surprise of both sides the proviso was adopted by a vote of 83 to 64, the Democrats of the North supporting it with but three exceptions.
An effort was made in the Senate to remove the proviso, but the last day of the session the gavel fell while the proviso was being debated, the first instance in which a bill was defeated by speaking against time in the Senate.
Wilmot was vehemently assailed by most of the leaders of his party, but the growing anti-slavery sentiment in the North only served to inspire Wilmot in his great battle, and he developed wonderful power as a public disputant.
Wilmot’s contest for re-election in 1848 attracted the attention of the whole Nation, and his triumph did much to strengthen the anti-slavery movement throughout the North.
Opposition to the Wilmot Proviso was finally forced as a cardinal doctrine of the party. When Wilmot came up for re-election in 1850 he was nominated at the Democratic primaries, but the newspapers opposed him and his defeat was regarded as one of the first duties of those who desired the success of the Democracy against him, and it appeared as if a Whig was sure to be elected.
Conservative Democrats suggested that both the Democratic candidates withdraw and select another upon whom all could unite. Wilmot promptly agreed on condition that the one nominated would sustain his anti-slavery faith and be personally acceptable to himself. He was asked to suggest a man, and he named Galusha A. Grow, then a young member of the bar in Susquehanna County, who had studied law with him.
Grow was found by a committee in his mountain retreat and hurried back to make his battle. He was elected and became the Speaker of Congress in the trying days of the Civil War.
The year Wilmot retired from Congress he succeeded Hon. Horace Willston on the bench of the judicial district then composed of Bradford, Susquehanna and Sullivan Counties, and ably served in that capacity until 1857, when he resigned to become a candidate for the governorship against William F. Packer, by whom he was defeated. After his defeat, Wilmot, by appointment of Governor Pollock, resumed his place on the bench and served until 1861.
