calling for the annexation of Texas, the entire South Carolina
delegation voted "aye." During the congressional battle several South Caro-

Calhoun was of more significance. True, Calhoun's pro-slavery letter to
Lord Aberdeen was partly instrumental in the defeat of annexation in
April, 1844. Later that year, however, his advice and counsel to President

English abolitionist schemes in Texas, addressed to Aberdeen, the British foreign

became known publicly, it antagonized the antislavery forces in the North and thus set
back the cause of annexation.
