It was in May, 1862, that Bingham's opposition to Colonel Jennison began. We find this notice in the Missouri Statesman for May 16: “Mr. Geo. C. Bingham, State Treasurer, and as honorable and loyal a citizen as ever lived, is out in a scathing expose of the robberies, raids, murders and jayhawking
of Jennison. It is a long but terribly severe and, we doubt not, a truthful document and cannot fail to have a very damaging effect upon this prince of buckanies.” In writing to her sister June 20, 1863, Mrs. Bingham says: “Have you seen the resolutions adopted by the Emancipation Convention convened here some days since? Mr. Gratz Brown and Mr. Bingham came almost to blows during its sitting. Mr. Brown made a speech attacking with furious onslaught Governor Gamble, the State Officers, Mr. Bingham in particular, and upholding Jennison. Mr. Bingham replied telling him if he did not upon the instant take back the lies he had uttered, he would have satisfaction and that speedily before leaving the Hall, whereupon Mr. Brown backed down and came to his senses in double-quick time."
